Incompatible/important changes |
11 |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
12 |
|
13 |
- Adding disks with 'gnt-instance modify' now waits for the disks to sync per |
14 |
default. Specify --no-wait-for-sync to override this behavior. |
15 |
- The Ganeti python code now adheres to a private-module layout. In particular, |
16 |
the module 'ganeti' is no longer in the python search path. |
17 |
|
18 |
New features |
19 |
~~~~~~~~~~~~ |
20 |
- KVM hypervisors can now access RBD storage directly without having to |
21 |
go through a block device. |

|
29 |
Incompatible/important changes |
30 |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
31 |
|
32 |
- hroller now also plans for capacity to move non-redundant instances off |
33 |
any node to be rebooted; the old behavior of completely ignoring any |
34 |
non-redundant instances can be restored by adding the --ignore-non-redundant |
35 |
option. |
36 |
- The cluster option '--no-lvm-storage' was removed in favor of the new option |
37 |
'--enabled-disk-templates'. |
38 |
- On instance creation, disk templates no longer need to be specified |
39 |
with '-t'. The default disk template will be taken from the list of |
40 |
enabled disk templates. |
41 |
- The monitoring daemon is now running as root, in order to be able to collect |
42 |
information only available to root (such as the state of Xen instances). |
43 |
- The ConfD client is now IPv6 compatible. |
44 |
- File and shared file storage is no longer dis/enabled at configure time, |
45 |
but using the option '--enabled-disk-templates' at cluster initialization and |
46 |
modification. |
47 |
- The default directories for file and shared file storage are not anymore |
48 |
specified at configure time, but taken from the cluster's configuration. |
49 |
They can be set at cluster initialization and modification with |
50 |
'--file-storage-dir' and '--shared-file-storage-dir'. |
51 |
- Cluster verification now includes stricter checks regarding the |
52 |
default file and shared file storage directories. It now checks that |
53 |
the directories are explicitely allowed in the 'file-storage-paths' file and |
54 |
that the directories exist on all nodes. |
55 |
- The list of allowed disk templates in the instance policy and the list |
56 |
of cluster-wide enabled disk templates is now checked for consistency |
57 |
on cluster or group modification. On cluster initialization, the ipolicy |
58 |
disk templates are ensured to be a subset of the cluster-wide enabled |
59 |
disk templates. |
60 |
|
61 |
New features |
62 |
~~~~~~~~~~~~ |
63 |
|
64 |
- DRBD 8.4 support. Depending on the installed DRBD version, Ganeti now uses |
65 |
the correct command syntax. It is possible to use different DRBD versions |
66 |
on different nodes as long as they are compatible to each other. This |
67 |
enables rolling upgrades of DRBD with no downtime. As permanent operation |
68 |
of different DRBD versions within a node group is discouraged, |
69 |
``gnt-cluster verify`` will emit a warning if it detects such a situation. |
70 |
- New "inst-status-xen" data collector for the monitoring daemon, providing |
71 |
information about the state of the xen instances on the nodes. |
72 |
- New "lv" data collector for the monitoring daemon, collecting data about the |
73 |
logical volumes on the nodes, and pairing them with the name of the instances |
74 |
they belong to. |
75 |
- New "diskstats" data collector, collecting the data from /proc/diskstats and |
76 |
presenting them over the monitoring daemon interface. |
77 |
- The ConfD client is now IPv6 compatible. |
78 |
|
79 |

~~~~~~~~~~~~~~~~ |
81 |
The following new dependencies have been added. |
82 |
|
83 |
Python |
84 |
|
85 |
- ``python-mock`` (http://www.voidspace.org.uk/python/mock/) is now a required |
86 |
for the unit tests (and only used for testing). |
87 |
|
88 |
Haskell |
89 |
|
90 |
- ``hslogger`` (http://software.complete.org/hslogger) is now always |
91 |
required, even if confd is not enabled. |
92 |

Version 2.9.0 beta1 |
103 |
------------------- |
104 |
|
105 |
*(Released Thu, 29 Aug 2013)* |
106 |
|
107 |
This was the first beta release of the 2.9 series. All important changes |
108 |
are listed in the latest 2.9 entry. |
109 |
|
110 |
|
111 |
Version 2.8.0 |
112 |
------------- |
113 |
|
114 |
*(Released Mon, 30 Sep 2013)* |
115 |
|
116 |
Incompatible/important changes |
117 |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
118 |
|
119 |
- Instance policy can contain multiple instance specs, as described in |
120 |
the “Constrained instance sizes” section of :doc:`Partitioned Ganeti |
121 |
<design-partitioned>`. As a consequence, it's not possible to partially change |
122 |
or override instance specs. Bounding specs (min and max) can be specified as a |
123 |
whole using the new option ``--ipolicy-bounds-specs``, while standard |
124 |
specs use the new option ``--ipolicy-std-specs``. |
125 |
- The output of the info command of gnt-cluster, gnt-group, gnt-node, |
126 |
gnt-instance is a valid YAML object. |
127 |
- hail now honors network restrictions when allocating nodes. This led to an |
128 |
update of the IAllocator protocol. See the IAllocator documentation for |
129 |
details. |
130 |
- confd now only answers static configuration request over the network. luxid |
131 |
was extracted, listens on the local LUXI socket and responds to live queries. |
132 |
This allows finer grained permissions if using separate users. |
133 |
|
134 |
New features |
135 |
~~~~~~~~~~~~ |
136 |
|
137 |
- The :doc:`Remote API <rapi>` daemon now supports a command line flag |
138 |
to always require authentication, ``--require-authentication``. It can |
139 |
be specified in ``$sysconfdir/default/ganeti``. |
140 |
- A new cluster attribute 'enabled_disk_templates' is introduced. It will |
141 |
be used to manage the disk templates to be used by instances in the cluster. |
142 |
Initially, it will be set to a list that includes plain, drbd, if they were |
143 |
enabled by specifying a volume group name, and file and sharedfile, if those |
144 |
were enabled at configure time. Additionally, it will include all disk |
145 |
templates that are currently used by instances. The order of disk templates |
146 |
will be based on Ganeti's history of supporting them. In the future, the |
147 |
first entry of the list will be used as a default disk template on instance |
148 |
creation. |
149 |
- ``cfgupgrade`` now supports a ``--downgrade`` option to bring the |
150 |
configuration back to the previous stable version. |
151 |
- Disk templates in group ipolicy can be restored to the default value. |
152 |
- Initial support for diskless instances and virtual clusters in QA. |
153 |
- More QA and unit tests for instance policies. |
154 |
- Every opcode now contains a reason trail (visible through ``gnt-job info``) |
155 |
describing why the opcode itself was executed. |
156 |
- The monitoring daemon is now available. It allows users to query the cluster |
157 |
for obtaining information about the status of the system. The daemon is only |
158 |
responsible for providing the information over the network: the actual data |
159 |
gathering is performed by data collectors (currently, only the DRBD status |
160 |
collector is available). |
161 |
- In order to help developers work on Ganeti, a new script |
162 |
(``devel/build_chroot``) is provided, for building a chroot that contains all |
163 |
the required development libraries and tools for compiling Ganeti on a Debian |
164 |
Squeeze system. |
165 |
- A new tool, ``harep``, for performing self-repair and recreation of instances |
166 |
in Ganeti has been added. |
167 |
- Split queries are enabled for tags, network, exports, cluster info, groups, |
168 |
jobs, nodes. |
169 |
- New command ``show-ispecs-cmd`` for ``gnt-cluster`` and ``gnt-group``. |
170 |
It prints the command line to set the current policies, to ease |
171 |
changing them. |
172 |
- Add the ``vnet_hdr`` HV parameter for KVM, to control whether the tap |
173 |
devices for KVM virtio-net interfaces will get created with VNET_HDR |
174 |
(IFF_VNET_HDR) support. If set to false, it disables offloading on the |
175 |
virtio-net interfaces, which prevents host kernel tainting and log |
176 |
flooding, when dealing with broken or malicious virtio-net drivers. |
177 |
It's set to true by default. |
178 |
- Instance failover now supports a ``--cleanup`` parameter for fixing previous |
179 |
failures. |
180 |
- Support 'viridian' parameter in Xen HVM |
181 |
- Support DSA SSH keys in bootstrap |
182 |
- To simplify the work of packaging frameworks that want to add the needed users |
183 |
and groups in a split-user setup themselves, at build time three files in |
184 |
``doc/users`` will be generated. The ``groups`` files contains, one per line, |
185 |
the groups to be generated, the ``users`` file contains, one per line, the |
186 |
users to be generated, optionally followed by their primary group, where |
187 |
important. The ``groupmemberships`` file contains, one per line, additional |
188 |
user-group membership relations that need to be established. The syntax of |
189 |
these files will remain stable in all future versions. |
190 |
|
191 |
|
192 |

311 |
Incompatible/important changes |
312 |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
313 |
|
314 |
- Instance policies for disk size were documented to be on a per-disk |
315 |
basis, but hail applied them to the sum of all disks. This has been |
316 |
fixed. |
317 |
- ``hbal`` will now exit with status 0 if, during job execution over |
318 |
LUXI, early exit has been requested and all jobs are successful; |
319 |
before, exit status 1 was used, which cannot be differentiated from |
320 |
"job error" case |
321 |
- Compatibility with newer versions of rbd has been fixed |
322 |
- ``gnt-instance batch-create`` has been changed to use the bulk create |
323 |
opcode from Ganeti. This lead to incompatible changes in the format of |
324 |
the JSON file. It's now not a custom dict anymore but a dict |
325 |
compatible with the ``OpInstanceCreate`` opcode. |
326 |
- Parent directories for file storage need to be listed in |
327 |
``$sysconfdir/ganeti/file-storage-paths`` now. ``cfgupgrade`` will |
328 |
write the file automatically based on old configuration values, but it |
329 |
can not distribute it across all nodes and the file contents should be |
330 |
verified. Use ``gnt-cluster copyfile |
331 |
$sysconfdir/ganeti/file-storage-paths`` once the cluster has been |
332 |
upgraded. The reason for requiring this list of paths now is that |
333 |
before it would have been possible to inject new paths via RPC, |
334 |
allowing files to be created in arbitrary locations. The RPC protocol |
335 |
is protected using SSL/X.509 certificates, but as a design principle |
336 |
Ganeti does not permit arbitrary paths to be passed. |
337 |
- The parsing of the variants file for OSes (see |
338 |
:manpage:`ganeti-os-interface(7)`) has been slightly changed: now empty |
339 |
lines and comment lines (starting with ``#``) are ignored for better |
340 |
readability. |
341 |
- The ``setup-ssh`` tool added in Ganeti 2.2 has been replaced and is no |
342 |
longer available. ``gnt-node add`` now invokes a new tool on the |
343 |
destination node, named ``prepare-node-join``, to configure the SSH |
344 |
daemon. Paramiko is no longer necessary to configure nodes' SSH |
345 |
daemons via ``gnt-node add``. |
346 |
- Draining (``gnt-cluster queue drain``) and un-draining the job queue |
347 |
(``gnt-cluster queue undrain``) now affects all nodes in a cluster and |
348 |
the flag is not reset after a master failover. |
349 |
- Python 2.4 has *not* been tested with this release. Using 2.6 or above |
350 |
is recommended. 2.6 will be mandatory from the 2.8 series. |
351 |
|
352 |
|
353 |
New features |
354 |
~~~~~~~~~~~~ |
355 |
|
356 |
- New network management functionality to support automatic allocation |
357 |
of IP addresses and managing of network parameters. See |
358 |
:manpage:`gnt-network(8)` for more details. |
359 |
- New external storage backend, to allow managing arbitrary storage |
360 |
systems external to the cluster. See |
361 |
:manpage:`ganeti-extstorage-interface(7)`. |
362 |
- New ``exclusive-storage`` node parameter added, restricted to |
363 |
nodegroup level. When it's set to true, physical disks are assigned in |
364 |
an exclusive fashion to instances, as documented in :doc:`Partitioned |
365 |
Ganeti <design-partitioned>`. Currently, only instances using the |
366 |
``plain`` disk template are supported. |
367 |
- The KVM hypervisor has been updated with many new hypervisor |
368 |
parameters, including a generic one for passing arbitrary command line |
369 |
values. See a complete list in :manpage:`gnt-instance(8)`. It is now |
370 |
compatible up to qemu 1.4. |
371 |
- A new tool, called ``mon-collector``, is the stand-alone executor of |
372 |
the data collectors for a monitoring system. As of this version, it |
373 |
just includes the DRBD data collector, that can be executed by calling |
374 |
``mon-collector`` using the ``drbd`` parameter. See |
375 |
:manpage:`mon-collector(7)`. |
376 |
- A new user option, :pyeval:`rapi.RAPI_ACCESS_READ`, has been added |
377 |
for RAPI users. It allows granting permissions to query for |
378 |
information to a specific user without giving |
379 |
:pyeval:`rapi.RAPI_ACCESS_WRITE` permissions. |
380 |
- A new tool named ``node-cleanup`` has been added. It cleans remains of |
381 |
a cluster from a machine by stopping all daemons, removing |
382 |
certificates and ssconf files. Unless the ``--no-backup`` option is |
383 |
given, copies of the certificates are made. |
384 |
- Instance creations now support the use of opportunistic locking, |
385 |
potentially speeding up the (parallel) creation of multiple instances. |
386 |
This feature is currently only available via the :doc:`RAPI |
387 |
<rapi>` interface and when an instance allocator is used. If the |
388 |
``opportunistic_locking`` parameter is set the opcode will try to |
389 |
acquire as many locks as possible, but will not wait for any locks |
390 |
held by other opcodes. If not enough resources can be found to |
391 |
allocate the instance, the temporary error code |
392 |
:pyeval:`errors.ECODE_TEMP_NORES` is returned. The operation can be |
393 |
retried thereafter, with or without opportunistic locking. |
394 |
- New experimental linux-ha resource scripts. |
395 |
- Restricted-commands support: ganeti can now be asked (via command line |
396 |
or rapi) to perform commands on a node. These are passed via ganeti |
397 |
RPC rather than ssh. This functionality is restricted to commands |
398 |
specified on the ``$sysconfdir/ganeti/restricted-commands`` for security |
399 |
reasons. The file is not copied automatically. |
400 |
|
401 |
|
402 |
Misc changes |
403 |
~~~~~~~~~~~~ |
404 |
|
405 |
- Diskless instances are now externally mirrored (Issue 237). This for |
406 |
now has only been tested in conjunction with explicit target nodes for |
407 |
migration/failover. |
408 |
- Queries not needing locks or RPC access to the node can now be |
409 |
performed by the confd daemon, making them independent from jobs, and |
410 |
thus faster to execute. This is selectable at configure time. |
411 |
- The functionality for allocating multiple instances at once has been |
412 |
overhauled and is now also available through :doc:`RAPI <rapi>`. |
413 |
|
414 |
There are no significant changes from version 2.7.0~rc3. |
415 |
|
416 |
|
417 |
Version 2.7.0 rc3 |
418 |
----------------- |
419 |
|
420 |
*(Released Tue, 25 Jun 2013)* |
421 |
|
422 |

Version 2.7.0 rc2 |
433 |
----------------- |
434 |
|
435 |
*(Released Fri, 24 May 2013)* |
436 |
|
437 |
- ``devel/upload`` now works when ``/var/run`` on the target nodes is a |
438 |
symlink. |
439 |
- Disks added through ``gnt-instance modify`` or created through |
440 |
``gnt-instance recreate-disks`` are wiped, if the |
441 |
``prealloc_wipe_disks`` flag is set. |
442 |
- If wiping newly created disks fails, the disks are removed. Also, |
443 |
partial failures in creating disks through ``gnt-instance modify`` |
444 |
triggers a cleanup of the partially-created disks. |
445 |
- Removing the master IP address doesn't fail if the address has been |
446 |
already removed. |
447 |
- Fix ownership of the OS log dir |
448 |
- Workaround missing SO_PEERCRED constant (Issue 191) |
449 |
|
450 |
|
451 |
Version 2.7.0 rc1 |
452 |
----------------- |
453 |
|
454 |
*(Released Fri, 3 May 2013)* |
455 |
|
456 |
This was the first release candidate of the 2.7 series. Since beta3: |
457 |
|
458 |
- Fix kvm compatibility with qemu 1.4 (Issue 389) |
459 |
- Documentation updates (admin guide, upgrade notes, install |
460 |
instructions) (Issue 372) |
461 |
- Fix gnt-group list nodes and instances count (Issue 436) |
462 |
- Fix compilation without non-mandatory libraries (Issue 441) |
463 |
- Fix xen-hvm hypervisor forcing nics to type 'ioemu' (Issue 247) |
464 |
- Make confd logging more verbose at INFO level (Issue 435) |
465 |
- Improve "networks" documentation in :manpage:`gnt-instance(8)` |
466 |
- Fix failure path for instance storage type conversion (Issue 229) |
467 |
- Update htools text backend documentation |
468 |
- Improve the renew-crypto section of :manpage:`gnt-cluster(8)` |
469 |
- Disable inter-cluster instance move for file-based instances, because |
470 |
it is dependant on instance export, which is not supported for |
471 |
file-based instances. (Issue 414) |
472 |
- Fix gnt-job crashes on non-ascii characters (Issue 427) |
473 |
- Fix volume group checks on non-vm-capable nodes (Issue 432) |
474 |
|
475 |

476 |
Version 2.7.0 beta3 |
477 |
------------------- |
478 |
|
479 |
*(Released Mon, 22 Apr 2013)* |
480 |
|
481 |
This was the third beta release of the 2.7 series. Since beta2: |
482 |
|
483 |
- Fix hail to verify disk instance policies on a per-disk basis (Issue 418). |
484 |
- Fix data loss on wrong usage of ``gnt-instance move`` |
485 |
- Properly export errors in confd-based job queries |
486 |
- Add ``users-setup`` tool |
487 |
- Fix iallocator protocol to report 0 as a disk size for diskless |
488 |
instances. This avoids hail breaking when a diskless instance is |
489 |
present. |
490 |
- Fix job queue directory permission problem that made confd job queries |
491 |
fail. This requires running an ``ensure-dirs --full-run`` on upgrade |
492 |
for access to archived jobs (Issue 406). |
493 |
- Limit the sizes of networks supported by ``gnt-network`` to something |
494 |
between a ``/16`` and a ``/30`` to prevent memory bloat and crashes. |
495 |
- Fix bugs in instance disk template conversion |
496 |
- Fix GHC 7 compatibility |
497 |
- Fix ``burnin`` install path (Issue 426). |
498 |
- Allow very small disk grows (Issue 347). |
499 |
- Fix a ``ganeti-noded`` memory bloat introduced in 2.5, by making sure |
500 |
that noded doesn't import masterd code (Issue 419). |
501 |
- Make sure the default metavg at cluster init is the same as the vg, if |
502 |
unspecified (Issue 358). |
503 |
- Fix cleanup of partially created disks (part of Issue 416) |
504 |
|
505 |
|
506 |
Version 2.7.0 beta2 |
507 |
------------------- |
508 |
|
509 |
*(Released Tue, 2 Apr 2013)* |
510 |
|
511 |
This was the second beta release of the 2.7 series. Since beta1: |
512 |
|
513 |
- Networks no longer have a "type" slot, since this information was |
514 |
unused in Ganeti: instead of it tags should be used. |
515 |
- The rapi client now has a ``target_node`` option to MigrateInstance. |
516 |
- Fix early exit return code for hbal (Issue 386). |
517 |
- Fix ``gnt-instance migrate/failover -n`` (Issue 396). |
518 |
- Fix ``rbd showmapped`` output parsing (Issue 312). |
519 |
- Networks are now referenced indexed by UUID, rather than name. This |
520 |
will require running cfgupgrade, from 2.7.0beta1, if networks are in |
521 |
use. |
522 |
- The OS environment now includes network information. |
523 |
- Deleting of a network is now disallowed if any instance nic is using |
524 |
it, to prevent dangling references. |
525 |
- External storage is now documented in man pages. |
526 |
- The exclusive_storage flag can now only be set at nodegroup level. |
527 |
- Hbal can now submit an explicit priority with its jobs. |
528 |
- Many network related locking fixes. |
529 |
- Bump up the required pylint version to 0.25.1. |
530 |
- Fix the ``no_remember`` option in RAPI client. |
531 |
- Many ipolicy related tests, qa, and fixes. |
532 |
- Many documentation improvements and fixes. |
533 |
- Fix building with ``--disable-file-storage``. |
534 |
- Fix ``-q`` option in htools, which was broken if passed more than |
535 |
once. |
536 |
- Some haskell/python interaction improvements and fixes. |
537 |
- Fix iallocator in case of missing LVM storage. |
538 |
- Fix confd config load in case of ``--no-lvm-storage``. |
539 |
- The confd/query functionality is now mentioned in the security |
540 |
documentation. |
541 |

543 |
Version 2.7.0 beta1 |
544 |
------------------- |
545 |
|
546 |
*(Released Wed, 6 Feb 2013)* |
547 |
|
548 |
This was the first beta release of the 2.7 series. All important changes |
549 |
are listed in the latest 2.7 entry. |
550 |
|
551 |
|
552 |
Version 2.6.2 |
553 |
------------- |
554 |
|
555 |
*(Released Fri, 21 Dec 2012)* |
556 |
|
557 |
Important behaviour change: hbal won't rebalance anymore instances which |
558 |
have the ``auto_balance`` attribute set to false. This was the intention |
559 |
all along, but until now it only skipped those from the N+1 memory |
560 |
reservation (DRBD-specific). |
561 |
|
562 |
A significant number of bug fixes in this release: |
563 |
|
564 |
- Fixed disk adoption interaction with ipolicy checks. |
565 |
- Fixed networking issues when instances are started, stopped or |
566 |
migrated, by forcing the tap device's MAC prefix to "fe" (issue 217). |
567 |
- Fixed the warning in cluster verify for shared storage instances not |
568 |
being redundant. |
569 |
- Fixed removal of storage directory on shared file storage (issue 262). |
570 |
- Fixed validation of LVM volume group name in OpClusterSetParams |
571 |
(``gnt-cluster modify``) (issue 285). |
572 |
- Fixed runtime memory increases (``gnt-instance modify -m``). |
573 |
- Fixed live migration under Xen's ``xl`` mode. |
574 |
- Fixed ``gnt-instance console`` with ``xl``. |
575 |
- Fixed building with newer Haskell compiler/libraries. |
576 |
- Fixed PID file writing in Haskell daemons (confd); this prevents |
577 |
restart issues if confd was launched manually (outside of |
578 |
``daemon-util``) while another copy of it was running |
579 |
- Fixed a type error when doing live migrations with KVM (issue 297) and |
580 |
the error messages for failing migrations have been improved. |
581 |
- Fixed opcode validation for the out-of-band commands (``gnt-node |
582 |
power``). |
583 |
- Fixed a type error when unsetting OS hypervisor parameters (issue |
584 |
311); now it's possible to unset all OS-specific hypervisor |
585 |
parameters. |
586 |
- Fixed the ``dry-run`` mode for many operations: verification of |
587 |
results was over-zealous but didn't take into account the ``dry-run`` |
588 |
operation, resulting in "wrong" failures. |
589 |
- Fixed bash completion in ``gnt-job list`` when the job queue has |
590 |
hundreds of entries; especially with older ``bash`` versions, this |
591 |
results in significant CPU usage. |
592 |
|
593 |
And lastly, a few other improvements have been made: |
594 |
|
595 |
- Added option to force master-failover without voting (issue 282). |
596 |
- Clarified error message on lock conflict (issue 287). |
597 |
- Logging of newly submitted jobs has been improved (issue 290). |
598 |
- Hostname checks have been made uniform between instance rename and |
599 |
create (issue 291). |
600 |
- The ``--submit`` option is now supported by ``gnt-debug delay``. |
601 |
- Shutting down the master daemon by sending SIGTERM now stops it from |
602 |
processing jobs waiting for locks; instead, those jobs will be started |
603 |
once again after the master daemon is started the next time (issue |
604 |
296). |
605 |
- Support for Xen's ``xl`` program has been improved (besides the fixes |
606 |
above). |
607 |
- Reduced logging noise in the Haskell confd daemon (only show one log |
608 |
entry for each config reload, instead of two). |
609 |
- Several man page updates and typo fixes. |
610 |
|
611 |
|
612 |
Version 2.6.1 |
613 |
------------- |
614 |
|
615 |
*(Released Fri, 12 Oct 2012)* |
616 |
|
617 |
A small bugfix release. Among the bugs fixed: |
618 |
|
619 |
- Fixed double use of ``PRIORITY_OPT`` in ``gnt-node migrate``, that |
620 |
made the command unusable. |
621 |
- Commands that issue many jobs don't fail anymore just because some jobs |
622 |
take so long that other jobs are archived. |
623 |
- Failures during ``gnt-instance reinstall`` are reflected by the exit |
624 |
status. |
625 |
- Issue 190 fixed. Check for DRBD in cluster verify is enabled only when |
626 |
DRBD is enabled. |
627 |
- When ``always_failover`` is set, ``--allow-failover`` is not required |
628 |
in migrate commands anymore. |
629 |
- ``bash_completion`` works even if extglob is disabled. |
630 |
- Fixed bug with locks that made failover for RDB-based instances fail. |
631 |
- Fixed bug in non-mirrored instance allocation that made Ganeti choose |
632 |
a random node instead of one based on the allocator metric. |
633 |
- Support for newer versions of pylint and pep8. |
634 |
- Hail doesn't fail anymore when trying to add an instance of type |
635 |
``file``, ``sharedfile`` or ``rbd``. |
636 |
- Added new Makefile target to rebuild the whole distribution, so that |
637 |
all files are included. |
638 |

640 |
Version 2.6.0 |
641 |
------------- |
642 |
|
643 |
*(Released Fri, 27 Jul 2012)* |
644 |
|
645 |
|
646 |
.. attention:: The ``LUXI`` protocol has been made more consistent |
647 |
regarding its handling of command arguments. This, however, leads to |
648 |
incompatibility issues with previous versions. Please ensure that you |
649 |
restart Ganeti daemons soon after the upgrade, otherwise most |
650 |
``LUXI`` calls (job submission, setting/resetting the drain flag, |
651 |
pausing/resuming the watcher, cancelling and archiving jobs, querying |
652 |
the cluster configuration) will fail. |
653 |
|
654 |
|
655 |
New features |
656 |
~~~~~~~~~~~~ |
657 |
|
658 |
Instance run status |
659 |
+++++++++++++++++++ |
660 |
|
661 |
The current ``admin_up`` field, which used to denote whether an instance |
662 |
should be running or not, has been removed. Instead, ``admin_state`` is |
663 |
introduced, with 3 possible values -- ``up``, ``down`` and ``offline``. |
664 |
|
665 |
The rational behind this is that an instance being “down” can have |
666 |
different meanings: |
667 |
|
668 |
- it could be down during a reboot |
669 |
- it could be temporarily be down for a reinstall |
670 |
- or it could be down because it is deprecated and kept just for its |
671 |
disk |
672 |
|
673 |
The previous Boolean state was making it difficult to do capacity |
674 |
calculations: should Ganeti reserve memory for a down instance? Now, the |
675 |
tri-state field makes it clear: |
676 |
|
677 |
- in ``up`` and ``down`` state, all resources are reserved for the |
678 |
instance, and it can be at any time brought up if it is down |
679 |
- in ``offline`` state, only disk space is reserved for it, but not |
680 |
memory or CPUs |
681 |
|
682 |
The field can have an extra use: since the transition between ``up`` and |
683 |
``down`` and vice-versus is done via ``gnt-instance start/stop``, but |
684 |
transition between ``offline`` and ``down`` is done via ``gnt-instance |
685 |
modify``, it is possible to given different rights to users. For |
686 |
example, owners of an instance could be allowed to start/stop it, but |
687 |
not transition it out of the offline state. |
688 |
|
689 |
Instance policies and specs |
690 |
+++++++++++++++++++++++++++ |
691 |
|
692 |
In previous Ganeti versions, an instance creation request was not |
693 |
limited on the minimum size and on the maximum size just by the cluster |
694 |
resources. As such, any policy could be implemented only in third-party |
695 |
clients (RAPI clients, or shell wrappers over ``gnt-*`` |
696 |
tools). Furthermore, calculating cluster capacity via ``hspace`` again |
697 |
required external input with regards to instance sizes. |
698 |
|
699 |
In order to improve these workflows and to allow for example better |
700 |
per-node group differentiation, we introduced instance specs, which |
701 |
allow declaring: |
702 |
|
703 |
- minimum instance disk size, disk count, memory size, cpu count |
704 |
- maximum values for the above metrics |
705 |
- and “standard” values (used in ``hspace`` to calculate the standard |
706 |
sized instances) |
707 |
|
708 |
The minimum/maximum values can be also customised at node-group level, |
709 |
for example allowing more powerful hardware to support bigger instance |
710 |
memory sizes. |
711 |
|
712 |
Beside the instance specs, there are a few other settings belonging to |
713 |
the instance policy framework. It is possible now to customise, per |
714 |
cluster and node-group: |
715 |
|
716 |
- the list of allowed disk templates |
717 |
- the maximum ratio of VCPUs per PCPUs (to control CPU oversubscription) |
718 |
- the maximum ratio of instance to spindles (see below for more |
719 |
information) for local storage |
720 |
|
721 |
All these together should allow all tools that talk to Ganeti to know |
722 |
what are the ranges of allowed values for instances and the |
723 |
over-subscription that is allowed. |
724 |
|
725 |
For the VCPU/PCPU ratio, we already have the VCPU configuration from the |
726 |
instance configuration, and the physical CPU configuration from the |
727 |
node. For the spindle ratios however, we didn't track before these |
728 |
values, so new parameters have been added: |
729 |
|
730 |
- a new node parameter ``spindle_count``, defaults to 1, customisable at |
731 |
node group or node level |
732 |
- at new backend parameter (for instances), ``spindle_use`` defaults to 1 |
733 |
|
734 |
Note that spindles in this context doesn't need to mean actual |
735 |
mechanical hard-drives; it's just a relative number for both the node |
736 |
I/O capacity and instance I/O consumption. |
737 |
|
738 |
Instance migration behaviour |
739 |
++++++++++++++++++++++++++++ |
740 |
|
741 |
While live-migration is in general desirable over failover, it is |
742 |
possible that for some workloads it is actually worse, due to the |
743 |
variable time of the “suspend” phase during live migration. |
744 |
|
745 |
To allow the tools to work consistently over such instances (without |
746 |
having to hard-code instance names), a new backend parameter |
747 |
``always_failover`` has been added to control the migration/failover |
748 |
behaviour. When set to True, all migration requests for an instance will |
749 |
instead fall-back to failover. |
750 |
|
751 |
Instance memory ballooning |
752 |
++++++++++++++++++++++++++ |
753 |
|
754 |
Initial support for memory ballooning has been added. The memory for an |
755 |
instance is no longer fixed (backend parameter ``memory``), but instead |
756 |
can vary between minimum and maximum values (backend parameters |
757 |
``minmem`` and ``maxmem``). Currently we only change an instance's |
758 |
memory when: |
759 |
|
760 |
- live migrating or failing over and instance and the target node |
761 |
doesn't have enough memory |
762 |
- user requests changing the memory via ``gnt-instance modify |
763 |
--runtime-memory`` |
764 |
|
765 |
Instance CPU pinning |
766 |
++++++++++++++++++++ |
767 |
|
768 |
In order to control the use of specific CPUs by instance, support for |
769 |
controlling CPU pinning has been added for the Xen, HVM and LXC |
770 |
hypervisors. This is controlled by a new hypervisor parameter |
771 |
``cpu_mask``; details about possible values for this are in the |
772 |
:manpage:`gnt-instance(8)`. Note that use of the most specific (precise |
773 |
VCPU-to-CPU mapping) form will work well only when all nodes in your |
774 |
cluster have the same amount of CPUs. |
775 |
|
776 |
Disk parameters |
777 |
+++++++++++++++ |
778 |
|
779 |
Another area in which Ganeti was not customisable were the parameters |
780 |
used for storage configuration, e.g. how many stripes to use for LVM, |
781 |
DRBD resync configuration, etc. |
782 |
|
783 |
To improve this area, we've added disks parameters, which are |
784 |
customisable at cluster and node group level, and which allow to |
785 |
specify various parameters for disks (DRBD has the most parameters |
786 |
currently), for example: |
787 |
|
788 |
- DRBD resync algorithm and parameters (e.g. speed) |
789 |
- the default VG for meta-data volumes for DRBD |
790 |
- number of stripes for LVM (plain disk template) |
791 |
- the RBD pool |
792 |
|
793 |
These parameters can be modified via ``gnt-cluster modify -D …`` and |
794 |
``gnt-group modify -D …``, and are used at either instance creation (in |
795 |
case of LVM stripes, for example) or at disk “activation” time |
796 |
(e.g. resync speed). |
797 |
|
798 |
Rados block device support |
799 |
++++++++++++++++++++++++++ |
800 |
|
801 |
A Rados (http://ceph.com/wiki/Rbd) storage backend has been added, |
802 |
denoted by the ``rbd`` disk template type. This is considered |
803 |
experimental, feedback is welcome. For details on configuring it, see |
804 |
the :doc:`install` document and the :manpage:`gnt-cluster(8)` man page. |
805 |
|
806 |
Master IP setup |
807 |
+++++++++++++++ |
808 |
|
809 |
The existing master IP functionality works well only in simple setups (a |
810 |
single network shared by all nodes); however, if nodes belong to |
811 |
different networks, then the ``/32`` setup and lack of routing |
812 |
information is not enough. |
813 |
|
814 |
To allow the master IP to function well in more complex cases, the |
815 |
system was reworked as follows: |
816 |
|
817 |
- a master IP netmask setting has been added |
818 |
- the master IP activation/turn-down code was moved from the node daemon |
819 |
to a separate script |
820 |
- whether to run the Ganeti-supplied master IP script or a user-supplied |
821 |
on is a ``gnt-cluster init`` setting |
822 |
|
823 |
Details about the location of the standard and custom setup scripts are |
824 |
in the man page :manpage:`gnt-cluster(8)`; for information about the |
825 |
setup script protocol, look at the Ganeti-supplied script. |
826 |
|
827 |
SPICE support |
828 |
+++++++++++++ |
829 |
|
830 |
The `SPICE <http://www.linux-kvm.org/page/SPICE>`_ support has been |
831 |
improved. |
832 |
|
833 |
It is now possible to use TLS-protected connections, and when renewing |
834 |
or changing the cluster certificates (via ``gnt-cluster renew-crypto``, |
835 |
it is now possible to specify spice or spice CA certificates. Also, it |
836 |
is possible to configure a password for SPICE sessions via the |
837 |
hypervisor parameter ``spice_password_file``. |
838 |
|
839 |
There are also new parameters to control the compression and streaming |
840 |
options (e.g. ``spice_image_compression``, ``spice_streaming_video``, |
841 |
etc.). For details, see the man page :manpage:`gnt-instance(8)` and look |
842 |
for the spice parameters. |
843 |
|
844 |
Lastly, it is now possible to see the SPICE connection information via |
845 |
``gnt-instance console``. |
846 |
|
847 |
OVF converter |
848 |
+++++++++++++ |
849 |
|
850 |
A new tool (``tools/ovfconverter``) has been added that supports |
851 |
conversion between Ganeti and the `Open Virtualization Format |
852 |
<http://en.wikipedia.org/wiki/Open_Virtualization_Format>`_ (both to and |
853 |
from). |
854 |
|
855 |
This relies on the ``qemu-img`` tool to convert the disk formats, so the |
856 |
actual compatibility with other virtualization solutions depends on it. |
857 |
|
858 |
Confd daemon changes |
859 |
++++++++++++++++++++ |
860 |
|
861 |
The configuration query daemon (``ganeti-confd``) is now optional, and |
862 |
has been rewritten in Haskell; whether to use the daemon at all, use the |
863 |
Python (default) or the Haskell version is selectable at configure time |
864 |
via the ``--enable-confd`` parameter, which can take one of the |
865 |
``haskell``, ``python`` or ``no`` values. If not used, disabling the |
866 |
daemon will result in a smaller footprint; for larger systems, we |
867 |
welcome feedback on the Haskell version which might become the default |
868 |
in future versions. |
869 |
|
870 |
If you want to use ``gnt-node list-drbd`` you need to have the Haskell |
871 |
daemon running. The Python version doesn't implement the new call. |
872 |
|
873 |
|
874 |
User interface changes |
875 |
~~~~~~~~~~~~~~~~~~~~~~ |
876 |
|
877 |
We have replaced the ``--disks`` option of ``gnt-instance |
878 |
replace-disks`` with a more flexible ``--disk`` option, which allows |
879 |
adding and removing disks at arbitrary indices (Issue 188). Furthermore, |
880 |
disk size and mode can be changed upon recreation (via ``gnt-instance |
881 |
recreate-disks``, which accepts the same ``--disk`` option). |
882 |
|
883 |
As many people are used to a ``show`` command, we have added that as an |
884 |
alias to ``info`` on all ``gnt-*`` commands. |
885 |
|
886 |
The ``gnt-instance grow-disk`` command has a new mode in which it can |
887 |
accept the target size of the disk, instead of the delta; this can be |
888 |
more safe since two runs in absolute mode will be idempotent, and |
889 |
sometimes it's also easier to specify the desired size directly. |
890 |
|
891 |
Also the handling of instances with regard to offline secondaries has |
892 |
been improved. Instance operations should not fail because one of it's |
893 |
secondary nodes is offline, even though it's safe to proceed. |
894 |
|
895 |
A new command ``list-drbd`` has been added to the ``gnt-node`` script to |
896 |
support debugging of DRBD issues on nodes. It provides a mapping of DRBD |
897 |
minors to instance name. |
898 |
|
899 |
API changes |
900 |
~~~~~~~~~~~ |
901 |
|
902 |
RAPI coverage has improved, with (for example) new resources for |
903 |
recreate-disks, node power-cycle, etc. |
904 |
|
905 |
Compatibility |
906 |
~~~~~~~~~~~~~ |
907 |
|
908 |
There is partial support for ``xl`` in the Xen hypervisor; feedback is |
909 |
welcome. |
910 |
|
911 |
Python 2.7 is better supported, and after Ganeti 2.6 we will investigate |
912 |
whether to still support Python 2.4 or move to Python 2.6 as minimum |
913 |
required version. |
914 |
|
915 |
Support for Fedora has been slightly improved; the provided example |
916 |
init.d script should work better on it and the INSTALL file should |
917 |
document the needed dependencies. |
918 |
|
919 |
Internal changes |
920 |
~~~~~~~~~~~~~~~~ |
921 |
|
922 |
The deprecated ``QueryLocks`` LUXI request has been removed. Use |
923 |
``Query(what=QR_LOCK, ...)`` instead. |
924 |
|
925 |
The LUXI requests :pyeval:`luxi.REQ_QUERY_JOBS`, |
926 |
:pyeval:`luxi.REQ_QUERY_INSTANCES`, :pyeval:`luxi.REQ_QUERY_NODES`, |
927 |
:pyeval:`luxi.REQ_QUERY_GROUPS`, :pyeval:`luxi.REQ_QUERY_EXPORTS` and |
928 |
:pyeval:`luxi.REQ_QUERY_TAGS` are deprecated and will be removed in a |
929 |
future version. :pyeval:`luxi.REQ_QUERY` should be used instead. |
930 |
|
931 |
RAPI client: ``CertificateError`` now derives from |
932 |
``GanetiApiError``. This should make it more easy to handle Ganeti |
933 |
errors. |
934 |
|
935 |
Deprecation warnings due to PyCrypto/paramiko import in |
936 |
``tools/setup-ssh`` have been silenced, as usually they are safe; please |
937 |
make sure to run an up-to-date paramiko version, if you use this tool. |
938 |
|
939 |
The QA scripts now depend on Python 2.5 or above (the main code base |
940 |
still works with Python 2.4). |
941 |
|
942 |
The configuration file (``config.data``) is now written without |
943 |
indentation for performance reasons; if you want to edit it, it can be |
944 |
re-formatted via ``tools/fmtjson``. |
945 |
|
946 |
A number of bugs has been fixed in the cluster merge tool. |
947 |
|
948 |
``x509`` certification verification (used in import-export) has been |
949 |
changed to allow the same clock skew as permitted by the cluster |
950 |
verification. This will remove some rare but hard to diagnose errors in |
951 |
import-export. |
952 |
|
953 |
|
954 |
Version 2.6.0 rc4 |
955 |

962 |
instance, fix CDROM booting for KVM instances) |
963 |
- fixed node group modification of node parameters |
964 |
- fixed issue in LUClusterVerifyGroup with multi-group clusters |
965 |
- fixed generation of bash completion to ensure a stable ordering |
966 |

967 |
|
968 |
|
969 |

----------------- |
971 |
|
972 |
*(Released Fri, 13 Jul 2012)* |
973 |
|

978 |
- Fixed an inconsistency in the LUXI protocol with the provided |
979 |
arguments (NOT backwards compatible) |
980 |
- Fixed a bug with node groups ipolicy where ``min`` was greater than |
981 |
the cluster ``std`` value |
982 |
- Implemented a new ``gnt-node list-drbd`` call to list DRBD minors for |
983 |
easier instance debugging on nodes (requires ``hconfd`` to work) |
984 |
|
985 |
|
986 |
Version 2.6.0 rc2 |
987 |
----------------- |
988 |
|
989 |

998 |
- Added possibility to run activate-disks even though secondaries are |
999 |
offline. With this change it relaxes also the strictness on some other |
1000 |
commands which use activate disks internally: |
1001 |
* ``gnt-instance start|reboot|rename|backup|export`` |
1002 |
- Made it possible to remove safely an instance if its secondaries are |
1003 |
offline |

1045 |
|
1046 |
|
1047 |
Version 2.6.0 beta1 |
1048 |
------------------- |
1049 |
|
1050 |
*(Released Wed, 23 May 2012)* |
1051 |
|
1052 |
First beta release of 2.6. The following changes were done from beta1 to |
1053 |
beta2: |
1054 |
|
1055 |
- integrated patch for distributions without ``start-stop-daemon`` |
1056 |
- adapted example init.d script to work on Fedora |
1057 |
- fixed log handling in Haskell daemons |
1058 |
- adapted checks in the watcher for pycurl linked against libnss |
1059 |
- add partial support for ``xl`` instead of ``xm`` for Xen |
1060 |
- fixed a type issue in cluster verification |
1061 |
- fixed ssconf handling in the Haskell code (was breaking confd in IPv6 |
1062 |
clusters) |
1063 |
|
1064 |
Plus integrated fixes from the 2.5 branch: |
1065 |
|
1066 |
- fixed ``kvm-ifup`` to use ``/bin/bash`` |
1067 |
- fixed parallel build failures |
1068 |
- KVM live migration when using a custom keymap |
1069 |
|
1070 |
|
1071 |
Version 2.5.2 |
1072 |
------------- |
1073 |
|
1074 |
*(Released Tue, 24 Jul 2012)* |
1075 |
|
1076 |
A small bugfix release, with no new features: |
1077 |
|
1078 |
- fixed bash-isms in kvm-ifup, for compatibility with systems which use a |
1079 |
different default shell (e.g. Debian, Ubuntu) |
1080 |
- fixed KVM startup and live migration with a custom keymap (fixes Issue |
1081 |
243 and Debian bug #650664) |
1082 |
- fixed compatibility with KVM versions that don't support multiple boot |
1083 |
devices (fixes Issue 230 and Debian bug #624256) |
1084 |
|
1085 |
Additionally, a few fixes were done to the build system (fixed parallel |
1086 |
build failures) and to the unittests (fixed race condition in test for |
1087 |
FileID functions, and the default enable/disable mode for QA test is now |
1088 |
customisable). |
1089 |
|
1090 |
|
1091 |
Version 2.5.1 |
1092 |
------------- |
1093 |
|
1094 |
*(Released Fri, 11 May 2012)* |
1095 |
|
1096 |
A small bugfix release. |
1097 |
|
1098 |
The main issues solved are on the topic of compatibility with newer LVM |
1099 |
releases: |
1100 |
|
1101 |
- fixed parsing of ``lv_attr`` field |
1102 |
- adapted to new ``vgreduce --removemissing`` behaviour where sometimes |
1103 |
the ``--force`` flag is needed |
1104 |
|
1105 |
Also on the topic of compatibility, ``tools/lvmstrap`` has been changed |
1106 |
to accept kernel 3.x too (was hardcoded to 2.6.*). |
1107 |
|
1108 |
A regression present in 2.5.0 that broke handling (in the gnt-* scripts) |
1109 |
of hook results and that also made display of other errors suboptimal |
1110 |
was fixed; the code behaves now like 2.4 and earlier. |
1111 |
|
1112 |
Another change in 2.5, the cleanup of the OS scripts environment, is too |
1113 |
aggressive: it removed even the ``PATH`` variable, which requires the OS |
1114 |
scripts to *always* need to export it. Since this is a bit too strict, |
1115 |
we now export a minimal PATH, the same that we export for hooks. |
1116 |
|
1117 |
The fix for issue 201 (Preserve bridge MTU in KVM ifup script) was |
1118 |
integrated into this release. |
1119 |
|
1120 |
Finally, a few other miscellaneous changes were done (no new features, |
1121 |
just small improvements): |
1122 |
|
1123 |
- Fix ``gnt-group --help`` display |
1124 |
- Fix hardcoded Xen kernel path |
1125 |
- Fix grow-disk handling of invalid units |
1126 |
- Update synopsis for ``gnt-cluster repair-disk-sizes`` |
1127 |
- Accept both PUT and POST in noded (makes future upgrade to 2.6 easier) |
1128 |
|
1129 |
|
1130 |
Version 2.5.0 |
1131 |
------------- |
1132 |
|
1133 |
*(Released Thu, 12 Apr 2012)* |
1134 |
|
1135 |
Incompatible/important changes and bugfixes |
1136 |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
1137 |
|
1138 |
- The default of the ``/2/instances/[instance_name]/rename`` RAPI |
1139 |
resource's ``ip_check`` parameter changed from ``True`` to ``False`` |
1140 |
to match the underlying LUXI interface. |
1141 |
- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use |
1142 |
body parameters, see :doc:`RAPI documentation <rapi>`. The server does |
1143 |
not maintain backwards-compatibility as the underlying operation |
1144 |
changed in an incompatible way. The RAPI client can talk to old |
1145 |
servers, but it needs to be told so as the return value changed. |
1146 |
- When creating file-based instances via RAPI, the ``file_driver`` |
1147 |
parameter no longer defaults to ``loop`` and must be specified. |
1148 |
- The deprecated ``bridge`` NIC parameter is no longer supported. Use |
1149 |
``link`` instead. |
1150 |
- Support for the undocumented and deprecated RAPI instance creation |
1151 |
request format version 0 has been dropped. Use version 1, supported |
1152 |
since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead. |
1153 |
- Pyparsing 1.4.6 or above is required, see :doc:`installation |
1154 |
documentation <install>`. |
1155 |
- The "cluster-verify" hooks are now executed per group by the |
1156 |
``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior |
1157 |
if you just run ``gnt-cluster verify``, which generates one opcode per |
1158 |
group. |
1159 |
- The environment as passed to the OS scripts is cleared, and thus no |
1160 |
environment variables defined in the node daemon's environment will be |
1161 |
inherited by the scripts. |
1162 |
- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been |
1163 |
deprecated. |
1164 |
- :doc:`New iallocator modes <design-multi-reloc>` have been added to |
1165 |
support operations involving multiple node groups. |
1166 |
- Offline nodes are ignored when failing over an instance. |
1167 |
- Support for KVM version 1.0, which changed the version reporting format |
1168 |
from 3 to 2 digits. |
1169 |
- TCP/IP ports used by DRBD disks are returned to a pool upon instance |
1170 |
removal. |
1171 |
- ``Makefile`` is now compatible with Automake 1.11.2 |
1172 |
- Includes all bugfixes made in the 2.4 series |
1173 |
|
1174 |
New features |
1175 |
~~~~~~~~~~~~ |
1176 |
|
1177 |
- The ganeti-htools project has been merged into the ganeti-core source |
1178 |
tree and will be built as part of Ganeti (see :doc:`install-quick`). |
1179 |
- Implemented support for :doc:`shared storage <design-shared-storage>`. |
1180 |
- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting |
1181 |
GPT-style partition tables (requires `parted |
1182 |
<http://www.gnu.org/s/parted/>`_). |
1183 |
- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor. |
1184 |
- Allowed adding tags on instance creation. |
1185 |
- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`) |
1186 |
- Allow instances to be started in a paused state, enabling the user to |
1187 |
see the complete console output on boot using the console. |
1188 |
- Added new hypervisor flag to control default reboot behaviour |
1189 |
(``reboot_behavior``). |
1190 |
- Added support for KVM keymaps (hypervisor parameter ``keymap``). |
1191 |
- Improved out-of-band management support: |
1192 |
|
1193 |
- Added ``gnt-node health`` command reporting the health status of |
1194 |
nodes. |
1195 |
- Added ``gnt-node power`` command to manage power status of nodes. |
1196 |
- Added command for emergency power-off (EPO), ``gnt-cluster epo``. |
1197 |
|
1198 |
- Instance migration can fall back to failover if instance is not |
1199 |
running. |
1200 |
- Filters can be used when listing nodes, instances, groups and locks; |
1201 |
see :manpage:`ganeti(7)` manpage. |
1202 |
- Added post-execution status as variables to :doc:`hooks <hooks>` |
1203 |
environment. |
1204 |
- Instance tags are exported/imported together with the instance. |
1205 |
- When given an explicit job ID, ``gnt-job info`` will work for archived |
1206 |
jobs. |
1207 |
- Jobs can define dependencies on other jobs (not yet supported via |
1208 |
RAPI or command line, but used by internal commands and usable via |
1209 |
LUXI). |
1210 |
|
1211 |
- Lock monitor (``gnt-debug locks``) shows jobs waiting for |
1212 |
dependencies. |
1213 |
|
1214 |
- Instance failover is now available as a RAPI resource |
1215 |
(``/2/instances/[instance_name]/failover``). |
1216 |
- ``gnt-instance info`` defaults to static information if primary node |
1217 |
is offline. |
1218 |
- Opcodes have a new ``comment`` attribute. |
1219 |
- Added basic SPICE support to KVM hypervisor. |
1220 |
- ``tools/ganeti-listrunner`` allows passing of arguments to executable. |
1221 |
|
1222 |
Node group improvements |
1223 |
~~~~~~~~~~~~~~~~~~~~~~~ |
1224 |
|
1225 |
- ``gnt-cluster verify`` has been modified to check groups separately, |
1226 |
thereby improving performance. |
1227 |
- Node group support has been added to ``gnt-cluster verify-disks``, |
1228 |
which now operates per node group. |
1229 |
- Watcher has been changed to work better with node groups. |
1230 |
|
1231 |
- One process and state file per node group. |
1232 |
- Slow watcher in one group doesn't block other group's watcher. |
1233 |
|
1234 |
- Added new command, ``gnt-group evacuate``, to move all instances in a |
1235 |
node group to other groups. |
1236 |
- Added ``gnt-instance change-group`` to move an instance to another |
1237 |
node group. |
1238 |
- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support |
1239 |
per-group operations. |
1240 |
- Node groups can be tagged. |
1241 |
- Some operations switch from an exclusive to a shared lock as soon as |
1242 |
possible. |
1243 |
- Instance's primary and secondary nodes' groups are now available as |
1244 |
query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group`` |
1245 |
and ``snodes.group.uuid``). |
1246 |
|
1247 |
Misc |
1248 |
~~~~ |
1249 |
|
1250 |
- Numerous updates to documentation and manpages. |
1251 |
|
1252 |
- :doc:`RAPI <rapi>` documentation now has detailed parameter |
1253 |
descriptions. |
1254 |
- Some opcode/job results are now also documented, see :doc:`RAPI |
1255 |
<rapi>`. |
1256 |
|
1257 |
- A lockset's internal lock is now also visible in lock monitor. |
1258 |
- Log messages from job queue workers now contain information about the |
1259 |
opcode they're processing. |
1260 |
- ``gnt-instance console`` no longer requires the instance lock. |
1261 |
- A short delay when waiting for job changes reduces the number of LUXI |
1262 |
requests significantly. |
1263 |
- DRBD metadata volumes are overwritten with zeros during disk creation. |
1264 |
- Out-of-band commands no longer acquire the cluster lock in exclusive |
1265 |
mode. |
1266 |
- ``devel/upload`` now uses correct permissions for directories. |
1267 |

|
1371 |
Many bug-fixes and a few small features: |
1372 |
|
1373 |
- Fixed argument order in ``ReserveLV`` and ``ReserveMAC`` which caused |
1374 |
issues when you tried to add an instance with two MAC addresses in one |
1375 |
request |
1376 |
- KVM: fixed per-instance stored UID value |
1377 |
- KVM: configure bridged NICs at migration start |
1378 |
- KVM: Fix a bug where instance will not start with never KVM versions |
1379 |
(>= 0.14) |
1380 |
- Added OS search path to ``gnt-cluster info`` |
1381 |
- Fixed an issue with ``file_storage_dir`` where you were forced to |
1382 |
provide an absolute path, but the documentation states it is a |
1383 |
relative path, the documentation was right |
1384 |
- Added a new parameter to instance stop/start called ``--no-remember`` |
1385 |
that will make the state change to not be remembered |
1386 |
- Implemented ``no_remember`` at RAPI level |
1387 |
- Improved the documentation |
1388 |
- Node evacuation: don't call IAllocator if node is already empty |
1389 |
- Fixed bug in DRBD8 replace disks on current nodes |
1390 |
- Fixed bug in recreate-disks for DRBD instances |
1391 |

1402 |
Version 2.4.2 |
1403 |
------------- |
1404 |
|
1405 |
*(Released Thu, 12 May 2011)* |
1406 |
|
1407 |
Many bug-fixes and a few new small features: |
1408 |
|
1409 |
- Fixed a bug related to log opening failures |
1410 |
- Fixed a bug in instance listing with orphan instances |
1411 |
- Fixed a bug which prevented resetting the cluster-level node parameter |
1412 |
``oob_program`` to the default |
1413 |
- Many fixes related to the ``cluster-merge`` tool |
1414 |
- Fixed a race condition in the lock monitor, which caused failures |
1415 |
during (at least) creation of many instances in parallel |
1416 |
- Improved output for gnt-job info |
1417 |
- Removed the quiet flag on some ssh calls which prevented debugging |
1418 |
failures |
1419 |
- Improved the N+1 failure messages in cluster verify by actually |
1420 |
showing the memory values (needed and available) |
1421 |
- Increased lock attempt timeouts so that when executing long operations |
1422 |
(e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire' |
1423 |
too early and thus prevent the use of the 'fair' mechanism |
1424 |
- Changed instance query data (``gnt-instance info``) to not acquire |
1425 |
locks unless needed, thus allowing its use on locked instance if only |
1426 |
static information is asked for |
1427 |
- Improved behaviour with filesystems that do not support rename on an |
1428 |
opened file |
1429 |
- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which |
1430 |
kept locks on all nodes during the wipe, which is unneeded |
1431 |
- Fixed ``gnt-watcher`` handling of errors during hooks execution |
1432 |
- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than |
1433 |
10GiB) which caused the wipe to fail right at the end in some cases |
1434 |
- Fixed master IP activation when doing master failover with no-voting |
1435 |
- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of |
1436 |
the master node itself |
1437 |
- Fixed potential data-loss in under disk full conditions, where Ganeti |
1438 |
wouldn't check correctly the return code and would consider |
1439 |
partially-written files 'correct' |
1440 |
- Fixed bug related to multiple VGs and DRBD disk replacing |
1441 |
- Added new disk parameter ``metavg`` that allows placement of the meta |
1442 |
device for DRBD in a different volume group |
1443 |
- Fixed error handling in the node daemon when the system libc doesn't |
1444 |
have major number 6 (i.e. if ``libc.so.6`` is not the actual libc) |
1445 |
- Fixed lock release during replace-disks, which kept cluster-wide locks |
1446 |
when doing disk replaces with an iallocator script |
1447 |
- Added check for missing bridges in cluster verify |
1448 |
- Handle EPIPE errors while writing to the terminal better, so that |
1449 |
piping the output to e.g. ``less`` doesn't cause a backtrace |
1450 |
- Fixed rare case where a ^C during Luxi calls could have been |
1451 |
interpreted as server errors, instead of simply terminating |
1452 |
- Fixed a race condition in LUGroupAssignNodes (``gnt-group |
1453 |
assign-nodes``) |
1454 |
- Added a few more parameters to the KVM hypervisor, allowing a second |
1455 |
CDROM, custom disk type for CDROMs and a floppy image |
1456 |
- Removed redundant message in instance rename when the name is given |
1457 |
already as a FQDN |
1458 |
- Added option to ``gnt-instance recreate-disks`` to allow creating the |
1459 |
disks on new nodes, allowing recreation when the original instance |
1460 |
nodes are completely gone |
1461 |
- Added option when converting disk templates to DRBD to skip waiting |
1462 |
for the resync, in order to make the instance available sooner |
1463 |
- Added two new variables to the OS scripts environment (containing the |
1464 |
instance's nodes) |
1465 |
- Made the root_path and optional parameter for the xen-pvm hypervisor, |
1466 |
to allow use of ``pvgrub`` as bootloader |
1467 |
- Changed the instance memory modifications to only check out-of-memory |
1468 |
conditions on memory increases, and turned the secondary node warnings |
1469 |
into errors (they can still be overridden via ``--force``) |
1470 |
- Fixed the handling of a corner case when the Python installation gets |
1471 |
corrupted (e.g. a bad disk) while ganeti-noded is running and we try |
1472 |
to execute a command that doesn't exist |
1473 |
- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary |
1474 |
node of the instance returned failures during instance shutdown; this |
1475 |
adds the option ``--ignore-consistency`` to gnt-instance move |
1476 |
|
1477 |
And as usual, various improvements to the error messages, documentation |
1478 |
and man pages. |
1479 |
|
1480 |
|
1481 |
Version 2.4.1 |
1482 |
------------- |
1483 |
|
1484 |
*(Released Wed, 09 Mar 2011)* |
1485 |
|
1486 |
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote |
1487 |
the RAPI users file if run twice (even with ``--dry-run``). |
1488 |
|
1489 |
The release fixes that bug (nothing else changed). |
1490 |
|
1491 |
|
1492 |
Version 2.4.0 |
1493 |
------------- |
1494 |
|
1495 |
*(Released Mon, 07 Mar 2011)* |
1496 |
|
1497 |
Final 2.4.0 release. Just a few small fixes: |
1498 |
|
1499 |
- Fixed RAPI node evacuate |
1500 |
- Fixed the kvm-ifup script |
1501 |
- Fixed internal error handling for special job cases |
1502 |
- Updated man page to specify the escaping feature for options |
1503 |
|
1504 |
|
1505 |
Version 2.4.0 rc3 |
1506 |
----------------- |
1507 |
|
1508 |
*(Released Mon, 28 Feb 2011)* |
1509 |
|
1510 |
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible |
1511 |
that this feature wiped the disks of the wrong instance, leading to loss |
1512 |
of data. |
1513 |
|
1514 |
Other changes: |
1515 |
|
1516 |
- Fixed title of query field containing instance name |
1517 |
- Expanded the glossary in the documentation |
1518 |
- Fixed one unittest (internal issue) |
1519 |
|
1520 |
|
1521 |
Version 2.4.0 rc2 |
1522 |
----------------- |
1523 |
|
1524 |
*(Released Mon, 21 Feb 2011)* |
1525 |
|
1526 |
A number of bug fixes plus just a couple functionality changes. |
1527 |
|
1528 |
On the user-visible side, the ``gnt-* list`` command output has changed |
1529 |
with respect to "special" field states. The current rc1 style of display |
1530 |
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in |
1531 |
the default output mode special fields states are displayed as follows: |
1532 |
|
1533 |
- Offline resource: ``*`` |
1534 |
- Unavailable/not applicable: ``-`` |
1535 |
- Data missing (RPC failure): ``?`` |
1536 |
- Unknown field: ``??`` |
1537 |
|
1538 |
Another user-visible change is the addition of ``--force-join`` to |
1539 |
``gnt-node add``. |
1540 |
|
1541 |
As for bug fixes: |
1542 |
|
1543 |
- ``tools/cluster-merge`` has seen many fixes and is now enabled again |
1544 |
- Fixed regression in RAPI/instance reinstall where all parameters were |
1545 |
required (instead of optional) |
1546 |
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2 |
1547 |
- Fixed iallocator usage (offline nodes were not considered offline) |
1548 |
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes |
1549 |
- Fixed hypervisor and OS parameter validation with respect to |
1550 |
non-vm_capable nodes |
1551 |
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly |
1552 |
cosmetic) |
1553 |
- Fixed ``tools/listrunner`` with respect to agent-based usage |
1554 |
|
1555 |
|
1556 |
Version 2.4.0 rc1 |
1557 |
----------------- |
1558 |
|
1559 |
*(Released Fri, 4 Feb 2011)* |
1560 |
|
1561 |
Many changes and fixes since the beta1 release. While there were some |
1562 |
internal changes, the code has been mostly stabilised for the RC |
1563 |
release. |
1564 |
|
1565 |
Note: the dumb allocator was removed in this release, as it was not kept |
1566 |
up-to-date with the IAllocator protocol changes. It is recommended to |
1567 |
use the ``hail`` command from the ganeti-htools package. |
1568 |
|
1569 |
Note: the 2.4 and up versions of Ganeti are not compatible with the |
1570 |
0.2.x branch of ganeti-htools. You need to upgrade to |
1571 |
ganeti-htools-0.3.0 (or later). |
1572 |
|
1573 |
Regressions fixed from 2.3 |
1574 |
~~~~~~~~~~~~~~~~~~~~~~~~~~ |
1575 |
|
1576 |
- Fixed the ``gnt-cluster verify-disks`` command |
1577 |
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to |
1578 |
serially on nodes) |
1579 |
- Fixed disk adoption breakage |
1580 |
- Fixed wrong headers in instance listing for field aliases |
1581 |
|
1582 |
Other bugs fixed |
1583 |
~~~~~~~~~~~~~~~~ |
1584 |
|
1585 |
- Fixed corner case in KVM handling of NICs |
1586 |
- Fixed many cases of wrong handling of non-vm_capable nodes |
1587 |
- Fixed a bug where a missing instance symlink was not possible to |
1588 |
recreate with any ``gnt-*`` command (now ``gnt-instance |
1589 |
activate-disks`` does it) |
1590 |
- Fixed the volume group name as reported by ``gnt-cluster |
1591 |
verify-disks`` |
1592 |
- Increased timeouts for the import-export code, hopefully leading to |
1593 |
fewer aborts due network or instance timeouts |
1594 |
- Fixed bug in ``gnt-node list-storage`` |
1595 |
- Fixed bug where not all daemons were started on cluster |
1596 |
initialisation, but only at the first watcher run |
1597 |
- Fixed many bugs in the OOB implementation |
1598 |
- Fixed watcher behaviour in presence of instances with offline |
1599 |
secondaries |
1600 |
- Fixed instance list output for instances running on the wrong node |
1601 |
- a few fixes to the cluster-merge tool, but it still cannot merge |
1602 |
multi-node groups (currently it is not recommended to use this tool) |
1603 |
|
1604 |
|
1605 |
Improvements |
1606 |
~~~~~~~~~~~~ |
1607 |
|
1608 |
- Improved network configuration for the KVM hypervisor |
1609 |
- Added e1000 as a supported NIC for Xen-HVM |
1610 |
- Improved the lvmstrap tool to also be able to use partitions, as |
1611 |
opposed to full disks |
1612 |
- Improved speed of disk wiping (the cluster parameter |
1613 |
``prealloc_wipe_disks``, so that it has a low impact on the total time |
1614 |
of instance creations |
1615 |
- Added documentation for the OS parameters |
1616 |
- Changed ``gnt-instance deactivate-disks`` so that it can work if the |
1617 |
hypervisor is not responding |
1618 |
- Added display of blacklisted and hidden OS information in |
1619 |
``gnt-cluster info`` |
1620 |
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend, |
1621 |
NIC and node parameters, which might create problems with currently |
1622 |
invalid (but undetected) configuration files, but prevents validation |
1623 |
failures when unrelated parameters are modified |
1624 |
- Changed cluster initialisation to wait for the master daemon to become |
1625 |
available |
1626 |
- Expanded the RAPI interface: |
1627 |
|
1628 |
- Added config redistribution resource |
1629 |
- Added activation/deactivation of instance disks |
1630 |
- Added export of console information |
1631 |
|
1632 |
- Implemented log file reopening on SIGHUP, which allows using |
1633 |
logrotate(8) for the Ganeti log files |
1634 |
- Added a basic OOB helper script as an example |
1635 |
|
1636 |
|
1637 |
Version 2.4.0 beta1 |
1638 |
------------------- |
1639 |
|
1640 |
*(Released Fri, 14 Jan 2011)* |
1641 |
|
1642 |
User-visible |
1643 |
~~~~~~~~~~~~ |
1644 |
|
1645 |
- Fixed timezone issues when formatting timestamps |
1646 |
- Added support for node groups, available via ``gnt-group`` and other |
1647 |
commands |
1648 |
- Added out-of-band framework and management, see :doc:`design |
1649 |
document <design-oob>` |
1650 |
- Removed support for roman numbers from ``gnt-node list`` and |
1651 |
``gnt-instance list``. |
1652 |
- Allowed modification of master network interface via ``gnt-cluster |
1653 |
modify --master-netdev`` |
1654 |
- Accept offline secondaries while shutting down instance disks |
1655 |
- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors |
1656 |
- Added support for multiple LVM volume groups |
1657 |
- Avoid sorting nodes for ``gnt-node list`` if specific nodes are |
1658 |
requested |
1659 |
- Added commands to list available fields: |
1660 |
|
1661 |
- ``gnt-node list-fields`` |
1662 |
- ``gnt-group list-fields`` |
1663 |
- ``gnt-instance list-fields`` |
1664 |
|
1665 |
- Updated documentation and man pages |
1666 |
|
1667 |
Integration |
1668 |
~~~~~~~~~~~ |
1669 |
|
1670 |
- Moved ``rapi_users`` file into separate directory, now named |
1671 |
``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a |
1672 |
symlink |
1673 |
- Added new tool for running commands on many machines, |
1674 |
``tools/ganeti-listrunner`` |
1675 |
- Implemented more verbose result in ``OpInstanceConsole`` opcode, also |
1676 |
improving the ``gnt-instance console`` output |
1677 |
- Allowed customisation of disk index separator at ``configure`` time |
1678 |
- Export node group allocation policy to :doc:`iallocator <iallocator>` |
1679 |
- Added support for non-partitioned md disks in ``lvmstrap`` |
1680 |
- Added script to gracefully power off KVM instances |
1681 |
- Split ``utils`` module into smaller parts |
1682 |
- Changed query operations to return more detailed information, e.g. |
1683 |
whether an information is unavailable due to an offline node. To use |
1684 |
this new functionality, the LUXI call ``Query`` must be used. Field |
1685 |
information is now stored by the master daemon and can be retrieved |
1686 |
using ``QueryFields``. Instances, nodes and groups can also be queried |
1687 |
using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet |
1688 |
exposed via RAPI). The following commands make use of this |
1689 |

1690 |
|
1691 |
- ``gnt-group list`` |
1692 |
- ``gnt-group list-fields`` |

1914 |
|
1915 |
Version 2.2.0 rc0 |
1916 |
----------------- |
1917 |
|
1918 |
*(Released Fri, 30 Jul 2010)* |
1919 |
|
1920 |
Important change: the internal RPC mechanism between Ganeti nodes has |
1921 |
changed from using a home-grown http library (based on the Python base |
1922 |
libraries) to use the PycURL library. This requires that PycURL is |
1923 |
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked |
1924 |
against GnuTLS by default. cURL's support for GnuTLS had known issues |
1925 |
before cURL 7.21.0 and we recommend using the latest cURL release or |
1926 |
linking against OpenSSL. Most other distributions already link PycURL |
1927 |
and cURL against OpenSSL. The command:: |
1928 |
|
1929 |
python -c 'import pycurl; print pycurl.version' |
1930 |
|
1931 |
can be used to determine the libraries PycURL and cURL are linked |
1932 |
against. |
1933 |
|
1934 |
Other significant changes: |
1935 |
|
1936 |
- Rewrote much of the internals of the job queue, in order to achieve |
1937 |
better parallelism; this decouples job query operations from the job |
1938 |
processing, and it should allow much nicer behaviour of the master |
1939 |
daemon under load, and it also has uncovered some long-standing bugs |
1940 |
related to the job serialisation (now fixed) |
1941 |
- Added a default iallocator setting to the cluster parameters, |
1942 |
eliminating the need to always pass nodes or an iallocator for |
1943 |
operations that require selection of new node(s) |
1944 |
- Added experimental support for the LXC virtualization method |
1945 |
- Added support for OS parameters, which allows the installation of |
1946 |
instances to pass parameter to OS scripts in order to customise the |
1947 |
instance |
1948 |
- Added a hypervisor parameter controlling the migration type (live or |
1949 |
non-live), since hypervisors have various levels of reliability; this |
1950 |
has renamed the 'live' parameter to 'mode' |
1951 |
- Added a cluster parameter ``reserved_lvs`` that denotes reserved |
1952 |
logical volumes, meaning that cluster verify will ignore them and not |
1953 |
flag their presence as errors |
1954 |
- The watcher will now reset the error count for failed instances after |
1955 |
8 hours, thus allowing self-healing if the problem that caused the |
1956 |
instances to be down/fail to start has cleared in the meantime |
1957 |
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti |
1958 |
check for, and warn, if the drbd module parameter ``usermode_helper`` |
1959 |
is not consistent with the cluster-wide setting; this is needed to |
1960 |
make diagnose easier of failed drbd creations |
1961 |
- Started adding base IPv6 support, but this is not yet |
1962 |
enabled/available for use |
1963 |
- Rename operations (cluster, instance) will now return the new name, |
1964 |
which is especially useful if a short name was passed in |
1965 |
- Added support for instance migration in RAPI |
1966 |
- Added a tool to pre-configure nodes for the SSH setup, before joining |
1967 |
them to the cluster; this will allow in the future a simplified model |
1968 |
for node joining (but not yet fully enabled in 2.2); this needs the |
1969 |
paramiko python library |
1970 |
- Fixed handling of name-resolving errors |
1971 |
- Fixed consistency of job results on the error path |
1972 |
- Fixed master-failover race condition when executed multiple times in |
1973 |
sequence |
1974 |
- Fixed many bugs related to the job queue (mostly introduced during the |
1975 |
2.2 development cycle, so not all are impacting 2.1) |
1976 |
- Fixed instance migration with missing disk symlinks |
1977 |
- Fixed handling of unknown jobs in ``gnt-job archive`` |
1978 |
- And many other small fixes/improvements |
1979 |
|
1980 |
Internal changes: |
1981 |
|
1982 |
- Enhanced both the unittest and the QA coverage |
1983 |
- Switched the opcode validation to a generic model, and extended the |
1984 |
validation to all opcode parameters |
1985 |
- Changed more parts of the code that write shell scripts to use the |
1986 |
same class for this |
1987 |
- Switched the master daemon to use the asyncore library for the Luxi |
1988 |
server endpoint |
1989 |

Version 2.2.0 beta0 |
1992 |
------------------- |
1993 |
|
1994 |
*(Released Thu, 17 Jun 2010)* |
1995 |
|
1996 |
- Added tool (``move-instance``) and infrastructure to move instances |
1997 |
between separate clusters (see :doc:`separate documentation |
1998 |
<move-instance>` and :doc:`design document <design-2.2>`) |
1999 |
- Added per-request RPC timeout |
2000 |
- RAPI now requires a Content-Type header for requests with a body (e.g. |
2001 |
``PUT`` or ``POST``) which must be set to ``application/json`` (see |
2002 |
:rfc:`2616` (HTTP/1.1), section 7.2.1) |
2003 |
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not |
2004 |
reachable |
2005 |
- Implemented initial support for running Ganeti daemons as separate |
2006 |
users, see configure-time flags ``--with-user-prefix`` and |
2007 |
``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this |
2008 |
time) |
2009 |
- Instances can be removed after export (``gnt-backup export |
2010 |
--remove-instance``) |
2011 |
- Self-signed certificates generated by Ganeti now use a 2048 bit RSA |
2012 |
key (instead of 1024 bit) |
2013 |
- Added new cluster configuration file for cluster domain secret |
2014 |
- Import/export now use SSL instead of SSH |
2015 |
- Added support for showing estimated time when exporting an instance, |
2016 |
see the ``ganeti-os-interface(7)`` manpage and look for |
2017 |
``EXP_SIZE_FD`` |
2018 |

2055 |
|
2056 |
Bugfixes only: |
2057 |
- Add an option to only select some reboot types during qa/burnin. |
2058 |
(on some hypervisors consequent reboots are not supported) |
2059 |
- Fix infrequent race condition in master failover. Sometimes the old |
2060 |
master ip address would be still detected as up for a short time |
2061 |
after it was removed, causing failover to fail. |
2062 |
- Decrease mlockall warnings when the ctypes module is missing. On |
2063 |
Python 2.4 we support running even if no ctypes module is installed, |
2064 |
but we were too verbose about this issue. |
2065 |
- Fix building on old distributions, on which man doesn't have a |
2066 |
--warnings option. |
2067 |

2078 |
- Fix batch-create: broken in the whole 2.1 series due to a lookup on |
2079 |
a non-existing option |

silently ignoring broken ones |
2102 |
- Fix an RPC error reporting bug affecting, for example, RAPI client |
2103 |
users |
2104 |
- Fix bug triggered by different API version os-es on different nodes |
2105 |
- Fix a bug in instance startup with custom hvparams: OS level |
2106 |
parameters would fail to be applied. |
2107 |
- Fix the RAPI client under Python 2.6 (but more work is needed to |
2108 |
make it work completely well with OpenSSL) |
2109 |
- Fix handling of errors when resolving names from DNS |
2110 |

Version 2.1.3 |
2113 |
------------- |
2114 |
|
2115 |
*(Released Thu, 3 Jun 2010)* |
2116 |
|
2117 |
A medium sized development cycle. Some new features, and some |
2118 |
fixes/small improvements/cleanups. |
2119 |
|
2120 |
Significant features |
2121 |
~~~~~~~~~~~~~~~~~~~~ |
2122 |
|
2123 |
The node deamon now tries to mlock itself into memory, unless the |
2124 |
``--no-mlock`` flag is passed. It also doesn't fail if it can't write |
2125 |
its logs, and falls back to console logging. This allows emergency |
2126 |
features such as ``gnt-node powercycle`` to work even in the event of a |
2127 |
broken node disk (tested offlining the disk hosting the node's |
2128 |
filesystem and dropping its memory caches; don't try this at home) |
2129 |
|
2130 |
KVM: add vhost-net acceleration support. It can be tested with a new |
2131 |
enough version of the kernel and of qemu-kvm. |
2132 |
|
2133 |
KVM: Add instance chrooting feature. If you use privilege dropping for |
2134 |
your VMs you can also now force them to chroot to an empty directory, |
2135 |
before starting the emulated guest. |
2136 |
|
2137 |
KVM: Add maximum migration bandwith and maximum downtime tweaking |
2138 |
support (requires a new-enough version of qemu-kvm). |
2139 |
|
2140 |
Cluster verify will now warn if the master node doesn't have the master |
2141 |
ip configured on it. |
2142 |
|
2143 |
Add a new (incompatible) instance creation request format to RAPI which |
2144 |
supports all parameters (previously only a subset was supported, and it |
2145 |
wasn't possible to extend the old format to accomodate all the new |
2146 |
features. The old format is still supported, and a client can check for |
2147 |
this feature, before using it, by checking for its presence in the |
2148 |
``features`` RAPI resource. |
2149 |
|
2150 |
Now with ancient latin support. Try it passing the ``--roman`` option to |
2151 |
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list`` |
2152 |
(requires the python-roman module to be installed, in order to work). |
2153 |
|
2154 |
Other changes |
2155 |
~~~~~~~~~~~~~ |
2156 |
|
2157 |
As usual many internal code refactorings, documentation updates, and |
2158 |
such. Among others: |
2159 |
|
2160 |
- Lots of improvements and cleanups to the experimental Remote API |
2161 |
(RAPI) client library. |
2162 |
- A new unit test suite for the core daemon libraries. |
2163 |
- A fix to creating missing directories makes sure the umask is not |
2164 |
applied anymore. This enforces the same directory permissions |
2165 |
everywhere. |
2166 |
- Better handling terminating daemons with ctrl+c (used when running |
2167 |
them in debugging mode). |
2168 |
- Fix a race condition in live migrating a KVM instance, when stat() |
2169 |
on the old proc status file returned EINVAL, which is an unexpected |
2170 |
value. |
2171 |
- Fixed manpage checking with newer man and utf-8 charachters. But now |
2172 |
you need the en_US.UTF-8 locale enabled to build Ganeti from git. |
2173 |
|
2174 |
|
2175 |
Version 2.1.2.1 |
2176 |
--------------- |
2177 |
|
2178 |
*(Released Fri, 7 May 2010)* |
2179 |
|
2180 |
Fix a bug which prevented untagged KVM instances from starting. |
2181 |
|
2182 |
|
2183 |
Version 2.1.2 |
2184 |
------------- |
2185 |
|
2186 |
*(Released Fri, 7 May 2010)* |
2187 |
|
2188 |
Another release with a long development cycle, during which many |
2189 |
different features were added. |
2190 |
|
2191 |
Significant features |
2192 |
~~~~~~~~~~~~~~~~~~~~ |
2193 |
|
2194 |
The KVM hypervisor now can run the individual instances as non-root, to |
2195 |
reduce the impact of a VM being hijacked due to bugs in the |
2196 |
hypervisor. It is possible to run all instances as a single (non-root) |
2197 |
user, to manually specify a user for each instance, or to dynamically |
2198 |
allocate a user out of a cluster-wide pool to each instance, with the |
2199 |
guarantee that no two instances will run under the same user ID on any |
2200 |
given node. |
2201 |
|
2202 |
An experimental RAPI client library, that can be used standalone |
2203 |
(without the other Ganeti libraries), is provided in the source tree as |
2204 |
``lib/rapi/client.py``. Note this client might change its interface in |
2205 |
the future, as we iterate on its capabilities. |
2206 |
|
2207 |
A new command, ``gnt-cluster renew-crypto`` has been added to easily |
2208 |
replace the cluster's certificates and crypto keys. This might help in |
2209 |
case they have been compromised, or have simply expired. |
2210 |
|
2211 |
A new disk option for instance creation has been added that allows one |
2212 |
to "adopt" currently existing logical volumes, with data |
2213 |
preservation. This should allow easier migration to Ganeti from |
2214 |
unmanaged (or managed via other software) instances. |
2215 |
|
2216 |
Another disk improvement is the possibility to convert between redundant |
2217 |
(DRBD) and plain (LVM) disk configuration for an instance. This should |
2218 |
allow better scalability (starting with one node and growing the |
2219 |
cluster, or shrinking a two-node cluster to one node). |
2220 |
|
2221 |
A new feature that could help with automated node failovers has been |
2222 |
implemented: if a node sees itself as offline (by querying the master |
2223 |
candidates), it will try to shutdown (hard) all instances and any active |
2224 |
DRBD devices. This reduces the risk of duplicate instances if an |
2225 |
external script automatically failovers the instances on such nodes. To |
2226 |
enable this, the cluster parameter ``maintain_node_health`` should be |
2227 |
enabled; in the future this option (per the name) will enable other |
2228 |
automatic maintenance features. |
2229 |
|
2230 |
Instance export/import now will reuse the original instance |
2231 |
specifications for all parameters; that means exporting an instance, |
2232 |
deleting it and the importing it back should give an almost identical |
2233 |
instance. Note that the default import behaviour has changed from |
2234 |
before, where it created only one NIC; now it recreates the original |
2235 |
number of NICs. |
2236 |
|
2237 |
Cluster verify has added a few new checks: SSL certificates validity, |
2238 |
/etc/hosts consistency across the cluster, etc. |
2239 |
|
2240 |
Other changes |
2241 |
~~~~~~~~~~~~~ |
2242 |
|
2243 |
As usual, many internal changes were done, documentation fixes, |
2244 |
etc. Among others: |
2245 |
|
2246 |
- Fixed cluster initialization with disabled cluster storage (regression |
2247 |
introduced in 2.1.1) |
2248 |
- File-based storage supports growing the disks |
2249 |
- Fixed behaviour of node role changes |
2250 |
- Fixed cluster verify for some corner cases, plus a general rewrite of |
2251 |
cluster verify to allow future extension with more checks |
2252 |
- Fixed log spamming by watcher and node daemon (regression introduced |
2253 |
in 2.1.1) |
2254 |
- Fixed possible validation issues when changing the list of enabled |
2255 |
hypervisors |
2256 |
- Fixed cleanup of /etc/hosts during node removal |
2257 |
- Fixed RAPI response for invalid methods |
2258 |
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon |
2259 |
- Multiple small improvements to the KVM hypervisor (VNC usage, booting |
2260 |
from ide disks, etc.) |
2261 |
- Allow OS changes without re-installation (to record a changed OS |
2262 |
outside of Ganeti, or to allow OS renames) |
2263 |
- Allow instance creation without OS installation (useful for example if |
2264 |
the OS will be installed manually, or restored from a backup not in |
2265 |
Ganeti format) |
2266 |
- Implemented option to make cluster ``copyfile`` use the replication |
2267 |
network |
2268 |
- Added list of enabled hypervisors to ssconf (possibly useful for |
2269 |
external scripts) |
2270 |
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from |
2271 |
1.2 clusters |
2272 |
- A partial form of node re-IP is possible via node readd, which now |
2273 |
allows changed node primary IP |
2274 |
- Command line utilities now show an informational message if the job is |
2275 |
waiting for a lock |
2276 |
- The logs of the master daemon now show the PID/UID/GID of the |
2277 |
connected client |
2278 |
|
2279 |
|
2280 |
Version 2.1.1 |
2281 |
------------- |
2282 |
|
2283 |
*(Released Fri, 12 Mar 2010)* |
2284 |
|
2285 |
During the 2.1.0 long release candidate cycle, a lot of improvements and |
2286 |
changes have accumulated with were released later as 2.1.1. |
2287 |
|
2288 |
Major changes |
2289 |
~~~~~~~~~~~~~ |
2290 |
|
2291 |
The node evacuate command (``gnt-node evacuate``) was significantly |
2292 |
rewritten, and as such the IAllocator protocol was changed - a new |
2293 |
request type has been added. This unfortunate change during a stable |
2294 |
series is designed to improve performance of node evacuations; on |
2295 |
clusters with more than about five nodes and which are well-balanced, |
2296 |
evacuation should proceed in parallel for all instances of the node |
2297 |
being evacuated. As such, any existing IAllocator scripts need to be |
2298 |
updated, otherwise the above command will fail due to the unknown |
2299 |
request. The provided "dumb" allocator has not been updated; but the |
2300 |
ganeti-htools package supports the new protocol since version 0.2.4. |
2301 |
|
2302 |
Another important change is increased validation of node and instance |
2303 |
names. This might create problems in special cases, if invalid host |
2304 |
names are being used. |
2305 |
|
2306 |
Also, a new layer of hypervisor parameters has been added, that sits at |
2307 |
OS level between the cluster defaults and the instance ones. This allows |
2308 |
customisation of virtualization parameters depending on the installed |
2309 |
OS. For example instances with OS 'X' may have a different KVM kernel |
2310 |
(or any other parameter) than the cluster defaults. This is intended to |
2311 |
help managing a multiple OSes on the same cluster, without manual |
2312 |
modification of each instance's parameters. |
2313 |
|
2314 |
A tool for merging clusters, ``cluster-merge``, has been added in the |
2315 |
tools sub-directory. |
2316 |
|
2317 |
Bug fixes |
2318 |
~~~~~~~~~ |
2319 |
|
2320 |
- Improved the int/float conversions that should make the code more |
2321 |
robust in face of errors from the node daemons |
2322 |
- Fixed the remove node code in case of internal configuration errors |
2323 |
- Fixed the node daemon behaviour in face of inconsistent queue |
2324 |
directory (e.g. read-only file-system where we can't open the files |
2325 |
read-write, etc.) |
2326 |
- Fixed the behaviour of gnt-node modify for master candidate demotion; |
2327 |
now it either aborts cleanly or, if given the new "auto_promote" |
2328 |
parameter, will automatically promote other nodes as needed |
2329 |
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would |
2330 |
completely prevent Ganeti from working |
2331 |
- Fixed bug for instance export when not all disks were successfully |
2332 |
exported |
2333 |
- Fixed behaviour of node add when the new node is slow in starting up |
2334 |
the node daemon |
2335 |
- Fixed handling of signals in the LUXI client, which should improve |
2336 |
behaviour of command-line scripts |
2337 |
- Added checks for invalid node/instance names in the configuration (now |
2338 |
flagged during cluster verify) |
2339 |
- Fixed watcher behaviour for disk activation errors |
2340 |
- Fixed two potentially endless loops in http library, which led to the |
2341 |
RAPI daemon hanging and consuming 100% CPU in some cases |
2342 |
- Fixed bug in RAPI daemon related to hashed passwords |
2343 |
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM |
2344 |
instances |
2345 |
- Enhanced compatibility with non-Debian OSes, but not using absolute |
2346 |
path in some commands and allowing customisation of the ssh |
2347 |
configuration directory |
2348 |
- Fixed possible future issue with new Python versions by abiding to the |
2349 |
proper use of ``__slots__`` attribute on classes |
2350 |
- Added checks that should prevent directory traversal attacks |
2351 |
- Many documentation fixes based on feedback from users |
2352 |
|
2353 |
New features |
2354 |
~~~~~~~~~~~~ |
2355 |
|
2356 |
- Added an "early_release" more for instance replace disks and node |
2357 |
evacuate, where we release locks earlier and thus allow higher |
2358 |
parallelism within the cluster |
2359 |
- Added watcher hooks, intended to allow the watcher to restart other |
2360 |
daemons (e.g. from the ganeti-nbma project), but they can be used of |
2361 |
course for any other purpose |
2362 |
- Added a compile-time disable for DRBD barriers, to increase |
2363 |
performance if the administrator trusts the power supply or the |
2364 |
storage system to not lose writes |
2365 |
- Added the option of using syslog for logging instead of, or in |
2366 |
addition to, Ganeti's own log files |
2367 |
- Removed boot restriction for paravirtual NICs for KVM, recent versions |
2368 |
can indeed boot from a paravirtual NIC |
2369 |
- Added a generic debug level for many operations; while this is not |
2370 |
used widely yet, it allows one to pass the debug value all the way to |
2371 |
the OS scripts |
2372 |
- Enhanced the hooks environment for instance moves (failovers, |
2373 |
migrations) where the primary/secondary nodes changed during the |
2374 |
operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars |
2375 |
- Enhanced data validations for many user-supplied values; one important |
2376 |
item is the restrictions imposed on instance and node names, which |
2377 |
might reject some (invalid) host names |
2378 |
- Add a configure-time option to disable file-based storage, if it's not |
2379 |
needed; this allows greater security separation between the master |
2380 |
node and the other nodes from the point of view of the inter-node RPC |
2381 |
protocol |
2382 |
- Added user notification in interactive tools if job is waiting in the |
2383 |
job queue or trying to acquire locks |
2384 |
- Added log messages when a job is waiting for locks |
2385 |
- Added filtering by node tags in instance operations which admit |
2386 |
multiple instances (start, stop, reboot, reinstall) |
2387 |
- Added a new tool for cluster mergers, ``cluster-merge`` |
2388 |
- Parameters from command line which are of the form ``a=b,c=d`` can now |
2389 |
use backslash escapes to pass in values which contain commas, |
2390 |
e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value |
2391 |
``b,c`` |
2392 |
- For KVM, the instance name is the first parameter passed to KVM, so |
2393 |
that it's more visible in the process list |
2394 |
|
2395 |
|
2396 |
Version 2.1.0 |
2397 |
------------- |
2398 |
|
2399 |
*(Released Tue, 2 Mar 2010)* |
2400 |
|
2401 |
Ganeti 2.1 brings many improvements with it. Major changes: |
2402 |
|
2403 |
- Added infrastructure to ease automated disk repairs |
2404 |
- Added new daemon to export configuration data in a cheaper way than |
2405 |
using the remote API |
2406 |
- Instance NICs can now be routed instead of being associated with a |
2407 |
networking bridge |
2408 |
- Improved job locking logic to reduce impact of jobs acquiring multiple |
2409 |
locks waiting for other long-running jobs |
2410 |
|
2411 |
In-depth implementation details can be found in the Ganeti 2.1 design |
2412 |
document. |

2445 |
(``ssconf_master_candidates_ips``), node primary IP address |
2446 |
(``ssconf_node_primary_ips``) and node secondary IP address |
2447 |
(``ssconf_node_secondary_ips``) |

2464 |
``--verbose`` to restore previous behaviour) |
2465 |
- Added UUIDs to the main config entities (cluster, nodes, instances) |
2466 |

- Added ``--no-ssh-init`` option to ``gnt-cluster init`` |
2471 |
- Added new helper script to start and stop Ganeti daemons |
2472 |

2474 |
from one place |
2475 |
- Added more unittests |
2476 |
- Fixed critical bug in ganeti-masterd startup |
2477 |

|
2502 |
- Fix cleaner behaviour on nodes not in a cluster (Debian bug 568105) |
2503 |

2510 |
|
2511 |
*(Released Thu, 17 Dec 2009)* |
2512 |
|
2513 |
- Fix security issue due to missing validation of iallocator names; this |
2514 |
allows local and remote execution of arbitrary executables |
2515 |
- Fix failure of gnt-node list during instance removal |
2516 |
- Ship the RAPI documentation in the archive |
2517 |

Version 2.0.4 |
2520 |
------------- |
2521 |
|
2522 |
*(Released Wed, 30 Sep 2009)* |
2523 |
|
2524 |
- Fixed many wrong messages |
2525 |
- Fixed a few bugs related to the locking library |
2526 |
- Fixed MAC checking at instance creation time |
2527 |
- Fixed a DRBD parsing bug related to gaps in /proc/drbd |
2528 |
- Fixed a few issues related to signal handling in both daemons and |
2529 |
scripts |
2530 |
- Fixed the example startup script provided |
2531 |
- Fixed insserv dependencies in the example startup script (patch from |
2532 |
Debian) |
2533 |
- Fixed handling of drained nodes in the iallocator framework |
2534 |
- Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug |
2535 |
#528618) |
2536 |
- Fixed error related to invalid job IDs in job polling |
2537 |
- Fixed job/opcode persistence on unclean master shutdown |
2538 |
- Fixed handling of partial job processing after unclean master |
2539 |
shutdown |
2540 |
- Fixed error reporting from LUs, previously all errors were converted |
2541 |
into execution errors |
2542 |
- Fixed error reporting from burnin |
2543 |
- Decreased significantly the memory usage of the job queue |
2544 |
- Optimised slightly multi-job submission |
2545 |
- Optimised slightly opcode loading |
2546 |
- Backported the multi-job submit framework from the development |
2547 |
branch; multi-instance start and stop should be faster |
2548 |
- Added script to clean archived jobs after 21 days; this will reduce |
2549 |
the size of the queue directory |
2550 |
- Added some extra checks in disk size tracking |
2551 |
- Added an example ethers hook script |
2552 |
- Added a cluster parameter that prevents Ganeti from modifying of |
2553 |
/etc/hosts |
2554 |
- Added more node information to RAPI responses |
2555 |
- Added a ``gnt-job watch`` command that allows following the ouput of a |
2556 |
job |
2557 |
- Added a bind-address option to ganeti-rapi |
2558 |
- Added more checks to the configuration verify |
2559 |
- Enhanced the burnin script such that some operations can be retried |
2560 |
automatically |
2561 |
- Converted instance reinstall to multi-instance model |
2562 |
|
2563 |
|
2564 |
Version 2.0.3 |
2565 |
------------- |
2566 |
|
2567 |
*(Released Fri, 7 Aug 2009)* |
2568 |
|
2569 |
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
2570 |
to allow using the pre-2.0.2 behaviour in activation, if any existing |
2571 |
instances have mismatched disk sizes in the configuration |
2572 |
- Added ``gnt-cluster repair-disk-sizes`` command to check and update |
2573 |
any configuration mismatches for disk sizes |
2574 |
- Added ``gnt-master cluste-failover --no-voting`` to allow master |
2575 |
failover to work on two-node clusters |
2576 |
- Fixed the ``--net`` option of ``gnt-backup import``, which was |
2577 |
unusable |
2578 |
- Fixed detection of OS script errors in ``gnt-backup export`` |
2579 |
- Fixed exit code of ``gnt-backup export`` |
2580 |
|
2581 |
|
2582 |
Version 2.0.2 |
2583 |
------------- |
2584 |
|
2585 |
*(Released Fri, 17 Jul 2009)* |
2586 |
|
2587 |
- Added experimental support for stripped logical volumes; this should |
2588 |
enhance performance but comes with a higher complexity in the block |
2589 |
device handling; stripping is only enabled when passing |
2590 |
``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
2591 |
affected even in the non-stripped mode |
2592 |
- Improved resiliency against transient failures at the end of DRBD |
2593 |
resyncs, and in general of DRBD resync checks |
2594 |
- Fixed a couple of issues with exports and snapshot errors |
2595 |
- Fixed a couple of issues in instance listing |
2596 |
- Added display of the disk size in ``gnt-instance info`` |
2597 |
- Fixed checking for valid OSes in instance creation |
2598 |
- Fixed handling of the "vcpus" parameter in instance listing and in |
2599 |
general of invalid parameters |
2600 |
- Fixed http server library, and thus RAPI, to handle invalid |
2601 |
username/password combinations correctly; this means that now they |
2602 |
report unauthorized for queries too, not only for modifications, |
2603 |
allowing earlier detect of configuration problems |
2604 |
- Added a new "role" node list field, equivalent to the master/master |
2605 |
candidate/drained/offline flags combinations |
2606 |
- Fixed cluster modify and changes of candidate pool size |
2607 |
- Fixed cluster verify error messages for wrong files on regular nodes |
2608 |
- Fixed a couple of issues with node demotion from master candidate role |
2609 |
- Fixed node readd issues |
2610 |
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
2611 |
- Added a new ``--no-voting`` option for masterfailover to fix failover |
2612 |
on two-nodes clusters when the former master node is unreachable |
2613 |
- Added instance reinstall over RAPI |
2614 |
|
2615 |
|
2616 |
Version 2.0.1 |
2617 |
------------- |
2618 |
|
2619 |
*(Released Tue, 16 Jun 2009)* |
2620 |
|
2621 |
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
2622 |
allow re-adding the start in single-user option (regression from 1.2) |
2623 |
- the watcher writes the instance status to a file, to allow monitoring |
2624 |
to report the instance status (from the master) based on cached |
2625 |
results of the watcher's queries; while this can get stale if the |
2626 |
watcher is being locked due to other work on the cluster, this is |
2627 |
still an improvement |
2628 |
- the watcher now also restarts the node daemon and the rapi daemon if |
2629 |
they died |
2630 |
- fixed the watcher to handle full and drained queue cases |
2631 |
- hooks export more instance data in the environment, which helps if |
2632 |
hook scripts need to take action based on the instance's properties |
2633 |
(no longer need to query back into ganeti) |
2634 |
- instance failovers when the instance is stopped do not check for free |
2635 |
RAM, so that failing over a stopped instance is possible in low memory |
2636 |
situations |
2637 |
- rapi uses queries for tags instead of jobs (for less job traffic), and |
2638 |
for cluster tags it won't talk to masterd at all but read them from |
2639 |
ssconf |
2640 |
- a couple of error handling fixes in RAPI |
2641 |
- drbd handling: improved the error handling of inconsistent disks after |
2642 |
resync to reduce the frequency of "there are some degraded disks for |
2643 |
this instance" messages |
2644 |
- fixed a bug in live migration when DRBD doesn't want to reconnect (the |
2645 |
error handling path called a wrong function name) |
2646 |
|
2647 |
|
2648 |
Version 2.0.0 |
2649 |
------------- |
2650 |
|
2651 |
*(Released Wed, 27 May 2009)* |
2652 |
|
2653 |
- no changes from rc5 |
2654 |
|
2655 |
|
2656 |
Version 2.0 rc5 |
2657 |
--------------- |
2658 |
|
2659 |
*(Released Wed, 20 May 2009)* |
2660 |
|
2661 |
- fix a couple of bugs (validation, argument checks) |
2662 |
- fix ``gnt-cluster getmaster`` on non-master nodes (regression) |
2663 |
- some small improvements to RAPI and IAllocator |
2664 |
- make watcher automatically start the master daemon if down |
2665 |
|
2666 |
|
2667 |
Version 2.0 rc4 |
2668 |
--------------- |
2669 |
|
2670 |
*(Released Mon, 27 Apr 2009)* |
2671 |
|
2672 |
- change the OS list to not require locks; this helps with big clusters |
2673 |
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the |
2674 |
volume group is broken |
2675 |
- ``gnt-instance info``, without any arguments, doesn't run for all |
2676 |
instances anymore; either pass ``--all`` or pass the desired |
2677 |
instances; this helps against mistakes on big clusters where listing |
2678 |
the information for all instances takes a long time |
2679 |
- miscellaneous doc and man pages fixes |
2680 |
|
2681 |
|
2682 |
Version 2.0 rc3 |
2683 |
--------------- |
2684 |
|
2685 |
*(Released Wed, 8 Apr 2009)* |
2686 |
|
2687 |
- Change the internal locking model of some ``gnt-node`` commands, in |
2688 |
order to reduce contention (and blocking of master daemon) when |
2689 |
batching many creation/reinstall jobs |
2690 |
- Fixes to Xen soft reboot |
2691 |
- No longer build documentation at build time, instead distribute it in |
2692 |
the archive, in order to reduce the need for the whole docbook/rst |
2693 |
toolchains |
2694 |
|
2695 |
|
2696 |
Version 2.0 rc2 |
2697 |
--------------- |
2698 |
|
2699 |
*(Released Fri, 27 Mar 2009)* |
2700 |
|
2701 |
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0 |
2702 |
- Fix watcher startup sequence, improves the behaviour of busy clusters |
2703 |
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance |
2704 |
replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC |
2705 |
bind address and other places |
2706 |
- Some documentation fixes and updates |
2707 |
|
2708 |
|
2709 |
Version 2.0 rc1 |
2710 |
--------------- |
2711 |
|
2712 |
*(Released Mon, 2 Mar 2009)* |
2713 |
|
2714 |
- More documentation updates, now all docs should be more-or-less |
2715 |
up-to-date |
2716 |
- A couple of small fixes (mixed hypervisor clusters, offline nodes, |
2717 |
etc.) |
2718 |
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM |
2719 |
and KVM) |
2720 |
- Fix an issue related to $libdir/run/ganeti and cluster creation |
2721 |
|
2722 |
|
2723 |
Version 2.0 beta2 |
2724 |
----------------- |
2725 |
|
2726 |
*(Released Thu, 19 Feb 2009)* |
2727 |
|
2728 |
- Xen PVM and KVM have switched the default value for the instance root |
2729 |
disk to the first partition on the first drive, instead of the whole |
2730 |
drive; this means that the OS installation scripts must be changed |
2731 |
accordingly |
2732 |
- Man pages have been updated |
2733 |
- RAPI has been switched by default to HTTPS, and the exported functions |
2734 |
should all work correctly |
2735 |
- RAPI v1 has been removed |
2736 |
- Many improvements to the KVM hypervisor |
2737 |
- Block device errors are now better reported |
2738 |
- Many other bugfixes and small improvements |
2739 |
|
2740 |
|
2741 |
Version 2.0 beta1 |
2742 |
----------------- |
2743 |
|
2744 |
*(Released Mon, 26 Jan 2009)* |
2745 |
|
2746 |
- Version 2 is a general rewrite of the code and therefore the |
2747 |
differences are too many to list, see the design document for 2.0 in |
2748 |
the ``doc/`` subdirectory for more details |
2749 |
- In this beta version there is not yet a migration path from 1.2 (there |
2750 |
will be one in the final 2.0 release) |
2751 |
- A few significant changes are: |
2752 |
|
2753 |
- all commands are executed by a daemon (``ganeti-masterd``) and the |
2754 |
various ``gnt-*`` commands are just front-ends to it |
2755 |
- all the commands are entered into, and executed from a job queue, |
2756 |
see the ``gnt-job(8)`` manpage |
2757 |
- the RAPI daemon supports read-write operations, secured by basic |
2758 |
HTTP authentication on top of HTTPS |
2759 |
- DRBD version 0.7 support has been removed, DRBD 8 is the only |
2760 |
supported version (when migrating from Ganeti 1.2 to 2.0, you need |
2761 |
to migrate to DRBD 8 first while still running Ganeti 1.2) |
2762 |
- DRBD devices are using statically allocated minor numbers, which |
2763 |
will be assigned to existing instances during the migration process |
2764 |
- there is support for both Xen PVM and Xen HVM instances running on |
2765 |
the same cluster |
2766 |
- KVM virtualization is supported too |
2767 |
- file-based storage has been implemented, which means that it is |
2768 |
possible to run the cluster without LVM and DRBD storage, for |
2769 |
example using a shared filesystem exported from shared storage (and |
2770 |
still have live migration) |
2771 |
|
2772 |
|
2773 |
Version 1.2.7 |
2774 |
------------- |
2775 |
|
2776 |
*(Released Tue, 13 Jan 2009)* |
2777 |
|
2778 |
- Change the default reboot type in ``gnt-instance reboot`` to "hard" |
2779 |
- Reuse the old instance mac address by default on instance import, if |
2780 |
the instance name is the same. |
2781 |
- Handle situations in which the node info rpc returns incomplete |
2782 |
results (issue 46) |
2783 |
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify`` |
2784 |
- Improved version of batcher: |
2785 |
|
2786 |
- state file support |
2787 |
- instance mac address support |
2788 |
- support for HVM clusters/instances |
2789 |
|
2790 |
- Add an option to show the number of cpu sockets and nodes in |
2791 |
``gnt-node list`` |
2792 |
- Support OSes that handle more than one version of the OS api (but do |
2793 |
not change the current API in any other way) |
2794 |
- Fix ``gnt-node migrate`` |
2795 |
- ``gnt-debug`` man page |
2796 |
- Fixes various more typos and small issues |
2797 |
- Increase disk resync maximum speed to 60MB/s (from 30MB/s) |
2798 |
|
2799 |
|
2800 |
Version 1.2.6 |
2801 |
------------- |
2802 |
|
2803 |
*(Released Wed, 24 Sep 2008)* |
2804 |
|
2805 |
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
2806 |
type of disk exported to fully virtualized instances. |
2807 |
- provide access to the serial console of HVM instances |
2808 |
- instance auto_balance flag, set by default. If turned off it will |
2809 |
avoid warnings on cluster verify if there is not enough memory to fail |
2810 |
over an instance. in the future it will prevent automatically failing |
2811 |
it over when we will support that. |
2812 |
- batcher tool for instance creation, see ``tools/README.batcher`` |
2813 |
- ``gnt-instance reinstall --select-os`` to interactively select a new |
2814 |
operating system when reinstalling an instance. |
2815 |
- when changing the memory amount on instance modify a check has been |
2816 |
added that the instance will be able to start. also warnings are |
2817 |
emitted if the instance will not be able to fail over, if auto_balance |
2818 |
is true. |
2819 |
- documentation fixes |
2820 |
- sync fields between ``gnt-instance list/modify/add/import`` |
2821 |
- fix a race condition in drbd when the sync speed was set after giving |
2822 |
the device a remote peer. |
2823 |
|
2824 |
|
2825 |
Version 1.2.5 |
2826 |
------------- |
2827 |
|
2828 |
*(Released Tue, 22 Jul 2008)* |
2829 |
|
2830 |
- note: the allowed size and number of tags per object were reduced |
2831 |
- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups |
2832 |
- fixed twisted 8.x compatibility |
2833 |
- fixed ``gnt-instance replace-disks`` with iallocator |
2834 |
- add TCP keepalives on twisted connections to detect restarted nodes |
2835 |
- disk increase support, see ``gnt-instance grow-disk`` |
2836 |
- implement bulk node/instance query for RAPI |
2837 |
- add tags in node/instance listing (optional) |
2838 |
- experimental migration (and live migration) support, read the man page |
2839 |
for ``gnt-instance migrate`` |
2840 |
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
2841 |
has some small improvements in handling its state file |
2842 |
|
2843 |
|
2844 |
Version 1.2.4 |
2845 |
------------- |
2846 |
|
2847 |
*(Released Fri, 13 Jun 2008)* |
2848 |
|
2849 |
- Experimental readonly, REST-based remote API implementation; |
2850 |
automatically started on master node, TCP port 5080, if enabled by |
2851 |
``--enable-rapi`` parameter to configure script. |
2852 |
- Instance allocator support. Add and import instance accept a |
2853 |
``--iallocator`` parameter, and call that instance allocator to decide |
2854 |
which node to use for the instance. The iallocator document describes |
2855 |
what's expected from an allocator script. |
2856 |
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
2857 |
``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
2858 |
node is lost there is still enough memory to fail over the instances |
2859 |
that reside on it. |
2860 |
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
2861 |
``gnt-cluster verify``, to check for site-specific compliance. All the |
2862 |
hooks will run, and their output, if any, will be displayed. Any |
2863 |
failing hook will make the verification return an error value. |
2864 |
- ``gnt-cluster verify`` now checks that its peers are reachable on the |
2865 |
primary and secondary interfaces |
2866 |
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
2867 |
that is still declared as part of the cluster and has failed. |
2868 |
- ``gnt-* list`` commands now accept a new ``-o +field`` way of |
2869 |
specifying output fields, that just adds the chosen fields to the |
2870 |
default ones. |
2871 |
- ``gnt-backup`` now has a new ``remove`` command to delete an existing |
2872 |
export from the filesystem. |
2873 |
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
2874 |
have been added. Using them you can enable/disable acpi and pae |
2875 |
support, and specify a path for a cd image to be exported to the |
2876 |
instance. These parameters as the name suggest only work on HVM |
2877 |
clusters. |
2878 |
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
2879 |
PAE support will be set to the previously hardcoded values, but the |
2880 |
(previously hardcoded) path to the CDROM ISO image will be unset and |
2881 |
if required, needs to be set manually with ``gnt-instance modify`` |
2882 |
after the upgrade. |
2883 |
- The address to which an instance's VNC console is bound is now |
2884 |
selectable per-instance, rather than being cluster wide. Of course |
2885 |
this only applies to instances controlled via VNC, so currently just |
2886 |
applies to HVM clusters. |
2887 |
|
2888 |
|
2889 |
Version 1.2.3 |
2890 |
------------- |
2891 |
|
2892 |
*(Released Mon, 18 Feb 2008)* |
2893 |
|
2894 |
- more tweaks to the disk activation code (especially helpful for DRBD) |
2895 |
- change the default ``gnt-instance list`` output format, now there is |
2896 |
one combined status field (see the manpage for the exact values this |
2897 |
field will have) |
2898 |
- some more fixes for the mac export to hooks change |
2899 |
- make Ganeti not break with DRBD 8.2.x (which changed the version |
2900 |
format in ``/proc/drbd``) (issue 24) |
2901 |
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk |
2902 |
template, allowing migration from DRBD0.7+MD to DRBD8 |
2903 |
|
2904 |
|
2905 |
Version 1.2.2 |
2906 |
------------- |
2907 |
|
2908 |
*(Released Wed, 30 Jan 2008)* |
2909 |
|
2910 |
- fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM |
2911 |
support (issue 23) |
2912 |
- add command aliases infrastructure and a few aliases |
2913 |
- allow listing of VCPUs in the ``gnt-instance list`` and improve the |
2914 |
man pages and the ``--help`` option of ``gnt-node |
2915 |
list``/``gnt-instance list`` |
2916 |
- fix ``gnt-backup list`` with down nodes (issue 21) |
2917 |
- change the tools location (move from $pkgdatadir to $pkglibdir/tools) |
2918 |
- fix the dist archive and add a check for including svn/git files in |
2919 |
the future |
2920 |

- make logical volume code auto-activate LVs at disk activation time |
2936 |

2973 |
Upgrading is possible using the cfgupgrade utility. |
2974 |
- Add support for DRBD 8.0 (new disk template ``drbd``) which allows for |
2975 |
faster replace disks and is more stable (DRBD 8 has many improvements |
2976 |
compared to DRBD 0.7) |
2977 |
- Added command line tags support (see man pages for ``gnt-instance``, |
2978 |
``gnt-node``, ``gnt-cluster``) |
2979 |
- Added instance rename support |
2980 |
- Added multi-instance startup/shutdown |
2981 |
- Added cluster rename support |
2982 |
- Added ``gnt-node evacuate`` to simplify some node operations |
2983 |
- Added instance reboot operation that can speedup reboot as compared to |
2984 |
stop and start |
2985 |
- Soften the requirement that hostnames are in FQDN format |
2986 |
- The ``ganeti-watcher`` now activates drbd pairs after secondary node |
2987 |
reboots |
2988 |
- Removed dependency on debian's patched fping that uses the |
2989 |
non-standard ``-S`` option |
2990 |
