Version 2.6.0 beta1 |
6 |
------------------- |
7 |
|
8 |
*(unreleased)* |
9 |
|
10 |
- Deprecated ``admin_up`` field. Instead, ``admin_state`` is introduced, |
11 |
with 3 possible values -- ``up``, ``down`` and ``offline``. |
12 |
- Replaced ``--disks`` option of ``gnt-instance replace-disks`` with a |
13 |
more flexible ``--disk`` option. Now disk size and mode can be changed |
14 |
upon recreation. |
15 |
- Removed deprecated ``QueryLocks`` LUXI request. Use |
16 |
``Query(what=QR_LOCK, ...)`` instead. |

Version 2.5.0 rc5 |
20 |
----------------- |
21 |
|
22 |
*(Released Mon, 9 Jan 2012)* |

|
24 |
Incompatible/important changes and bugfixes |
25 |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
26 |
|
27 |
- The default of the ``/2/instances/[instance_name]/rename`` RAPI |
28 |
resource's ``ip_check`` parameter changed from ``True`` to ``False`` |
29 |
to match the underlying LUXI interface. |
30 |
- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use |
31 |
body parameters, see :doc:`RAPI documentation <rapi>`. The server does |
32 |
not maintain backwards-compatibility as the underlying operation |
33 |
changed in an incompatible way. The RAPI client can talk to old |
34 |
servers, but it needs to be told so as the return value changed. |
35 |
- When creating file-based instances via RAPI, the ``file_driver`` |
36 |
parameter no longer defaults to ``loop`` and must be specified. |
37 |
- The deprecated ``bridge`` NIC parameter is no longer supported. Use |
38 |
``link`` instead. |
39 |
- Support for the undocumented and deprecated RAPI instance creation |
40 |
request format version 0 has been dropped. Use version 1, supported |
41 |
since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead. |
42 |
- Pyparsing 1.4.6 or above is required, see :doc:`installation |
43 |
documentation <install>`. |
44 |
- The "cluster-verify" hooks are now executed per group by the |
45 |
``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior |
46 |
if you just run ``gnt-cluster verify``, which generates one opcode per |
47 |
group. |
48 |
- The environment as passed to the OS scripts is cleared, and thus no |
49 |
environment variables defined in the node daemon's environment will be |
50 |
inherited by the scripts. |
51 |
- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been |
52 |
deprecated. |
53 |
- :doc:`New iallocator modes <design-multi-reloc>` have been added to |
54 |
support operations involving multiple node groups. |
55 |
- Offline nodes are ignored when failing over an instance. |
56 |
- Support for KVM version 1.0, which changed the version reporting format |
57 |
from 3 to 2 digits. |
58 |
- Includes all bugfixes made in the 2.4 series |
59 |
|
60 |
New features |
61 |
~~~~~~~~~~~~ |
62 |
|
63 |
- The ganeti-htools project has been merged into the ganeti-core source |
64 |
tree and will be built as part of Ganeti (see :doc:`install-quick`). |
65 |
- Implemented support for :doc:`shared storage <design-shared-storage>`. |
66 |
- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting |
67 |
GPT-style partition tables (requires `parted |
68 |
<http://www.gnu.org/s/parted/>`_). |
69 |
- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor. |
70 |
- Allowed adding tags on instance creation. |
71 |
- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`) |
72 |
- Allow instances to be started in a paused state, enabling the user to |
73 |
see the complete console output on boot using the console. |
74 |
- Added new hypervisor flag to control default reboot behaviour |
75 |
(``reboot_behavior``). |
76 |
- Added support for KVM keymaps (hypervisor parameter ``keymap``). |
77 |
- Improved out-of-band management support: |
78 |
|
79 |
- Added ``gnt-node health`` command reporting the health status of |
80 |
nodes. |
81 |
- Added ``gnt-node power`` command to manage power status of nodes. |
82 |
- Added command for emergency power-off (EPO), ``gnt-cluster epo``. |
83 |
|
84 |
- Instance migration can fall back to failover if instance is not |
85 |
running. |
86 |
- Filters can be used when listing nodes, instances, groups and locks; |
87 |
see *ganeti(7)* manpage. |
88 |
- Added post-execution status as variables to :doc:`hooks <hooks>` |
89 |
environment. |
90 |
- Instance tags are exported/imported together with the instance. |
91 |
- When given an explicit job ID, ``gnt-job info`` will work for archived |
92 |
jobs. |
93 |
- Jobs can define dependencies on other jobs (not yet supported via |
94 |
RAPI or command line, but used by internal commands and usable via |
95 |
LUXI). |
96 |
|
97 |
- Lock monitor (``gnt-debug locks``) shows jobs waiting for |
98 |
dependencies. |
99 |
|
100 |
- Instance failover is now available as a RAPI resource |
101 |
(``/2/instances/[instance_name]/failover``). |
102 |
- ``gnt-instance info`` defaults to static information if primary node |
103 |
is offline. |
104 |
- Opcodes have a new ``comment`` attribute. |
105 |
- Added basic SPICE support to KVM hypervisor. |
106 |
- ``tools/ganeti-listrunner`` allows passing of arguments to executable. |
107 |
|
108 |
Node group improvements |
109 |
~~~~~~~~~~~~~~~~~~~~~~~ |
110 |
|
111 |
- ``gnt-cluster verify`` has been modified to check groups separately, |
112 |
thereby improving performance. |
113 |
- Node group support has been added to ``gnt-cluster verify-disks``, |
114 |
which now operates per node group. |
115 |
- Watcher has been changed to work better with node groups. |
116 |
|
117 |
- One process and state file per node group. |
118 |
- Slow watcher in one group doesn't block other group's watcher. |
119 |
|
120 |
- Added new command, ``gnt-group evacuate``, to move all instances in a |
121 |
node group to other groups. |
122 |
- Added ``gnt-instance change-group`` to move an instance to another |
123 |
node group. |
124 |
- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support |
125 |
per-group operations. |
126 |
- Node groups can be tagged. |
127 |
- Some operations switch from an exclusive to a shared lock as soon as |
128 |
possible. |
129 |
- Instance's primary and secondary nodes' groups are now available as |
130 |
query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group`` |
131 |
and ``snodes.group.uuid``). |
132 |
|
133 |
Misc |
134 |
~~~~ |
135 |
|
136 |
- Numerous updates to documentation and manpages. |
137 |
|
138 |
- :doc:`RAPI <rapi>` documentation now has detailed parameter |
139 |
descriptions. |
140 |
- Some opcode/job results are now also documented, see :doc:`RAPI |
141 |
<rapi>`. |
142 |
|
143 |
- A lockset's internal lock is now also visible in lock monitor. |
144 |
- Log messages from job queue workers now contain information about the |
145 |
opcode they're processing. |
146 |
- ``gnt-instance console`` no longer requires the instance lock. |
147 |
- A short delay when waiting for job changes reduces the number of LUXI |
148 |
requests significantly. |
149 |
- DRBD metadata volumes are overwritten with zeros during disk creation. |

237 |
|
238 |
Many bug-fixes and a few small features: |
239 |
|
240 |
- Fixed argument order in ``ReserveLV`` and ``ReserveMAC`` which caused |
241 |
issues when you tried to add an instance with two MAC addresses in one |
242 |
request |
243 |
- KVM: fixed per-instance stored UID value |
244 |
- KVM: configure bridged NICs at migration start |

246 |
(>= 0.14) |
247 |
- Added OS search path to ``gnt-cluster info`` |
248 |
- Fixed an issue with ``file_storage_dir`` where you were forced to |
249 |
provide an absolute path, but the documentation states it is a |
250 |
relative path, the documentation was right |
251 |
- Added a new parameter to instance stop/start called ``--no-remember`` |
252 |
that will make the state change to not be remembered |
253 |

256 |
- Fixed bug in DRBD8 replace disks on current nodes |
257 |
- Fixed bug in recreate-disks for DRBD instances |

|
268 |
|
269 |
Version 2.4.2 |
270 |
------------- |
271 |
|
272 |
*(Released Thu, 12 May 2011)* |
273 |
|
274 |
Many bug-fixes and a few new small features: |
275 |
|
276 |
- Fixed a bug related to log opening failures |
277 |
- Fixed a bug in instance listing with orphan instances |
278 |
- Fixed a bug which prevented resetting the cluster-level node parameter |
279 |
``oob_program`` to the default |
280 |
- Many fixes related to the ``cluster-merge`` tool |
281 |
- Fixed a race condition in the lock monitor, which caused failures |
282 |
during (at least) creation of many instances in parallel |
283 |
- Improved output for gnt-job info |
284 |
- Removed the quiet flag on some ssh calls which prevented debugging |
285 |
failures |
286 |
- Improved the N+1 failure messages in cluster verify by actually |
287 |
showing the memory values (needed and available) |
288 |
- Increased lock attempt timeouts so that when executing long operations |
289 |
(e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire' |
290 |
too early and thus prevent the use of the 'fair' mechanism |
291 |
- Changed instance query data (``gnt-instance info``) to not acquire |
292 |
locks unless needed, thus allowing its use on locked instance if only |
293 |
static information is asked for |
294 |
- Improved behaviour with filesystems that do not support rename on an |
295 |
opened file |
296 |
- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which |
297 |
kept locks on all nodes during the wipe, which is unneeded |
298 |
- Fixed ``gnt-watcher`` handling of errors during hooks execution |
299 |
- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than |
300 |
10GiB) which caused the wipe to fail right at the end in some cases |
301 |
- Fixed master IP activation when doing master failover with no-voting |
302 |
- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of |
303 |
the master node itself |
304 |
- Fixed potential data-loss in under disk full conditions, where Ganeti |
305 |
wouldn't check correctly the return code and would consider |
306 |
partially-written files 'correct' |
307 |
- Fixed bug related to multiple VGs and DRBD disk replacing |
308 |
- Added new disk parameter ``metavg`` that allows placement of the meta |
309 |
device for DRBD in a different volume group |
310 |
- Fixed error handling in the node daemon when the system libc doesn't |
311 |
have major number 6 (i.e. if ``libc.so.6`` is not the actual libc) |
312 |
- Fixed lock release during replace-disks, which kept cluster-wide locks |
313 |
when doing disk replaces with an iallocator script |
314 |
- Added check for missing bridges in cluster verify |
315 |
- Handle EPIPE errors while writing to the terminal better, so that |
316 |
piping the output to e.g. ``less`` doesn't cause a backtrace |
317 |
- Fixed rare case where a ^C during Luxi calls could have been |
318 |
interpreted as server errors, instead of simply terminating |
319 |
- Fixed a race condition in LUGroupAssignNodes (``gnt-group |
320 |
assign-nodes``) |
321 |
- Added a few more parameters to the KVM hypervisor, allowing a second |
322 |
CDROM, custom disk type for CDROMs and a floppy image |
323 |
- Removed redundant message in instance rename when the name is given |
324 |
already as a FQDN |
325 |
- Added option to ``gnt-instance recreate-disks`` to allow creating the |
326 |
disks on new nodes, allowing recreation when the original instance |
327 |
nodes are completely gone |
328 |
- Added option when converting disk templates to DRBD to skip waiting |
329 |
for the resync, in order to make the instance available sooner |
330 |
- Added two new variables to the OS scripts environment (containing the |
331 |
instance's nodes) |
332 |
- Made the root_path and optional parameter for the xen-pvm hypervisor, |
333 |
to allow use of ``pvgrub`` as bootloader |
334 |
- Changed the instance memory modifications to only check out-of-memory |
335 |
conditions on memory increases, and turned the secondary node warnings |
336 |
into errors (they can still be overridden via ``--force``) |
337 |
- Fixed the handling of a corner case when the Python installation gets |
338 |
corrupted (e.g. a bad disk) while ganeti-noded is running and we try |
339 |
to execute a command that doesn't exist |
340 |
- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary |
341 |
node of the instance returned failures during instance shutdown; this |
342 |
adds the option ``--ignore-consistency`` to gnt-instance move |
343 |
|
344 |
And as usual, various improvements to the error messages, documentation |
345 |
and man pages. |
346 |
|
347 |
|
348 |
Version 2.4.1 |
349 |
------------- |
350 |
|
351 |
*(Released Wed, 09 Mar 2011)* |
352 |
|
353 |
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote |
354 |
the RAPI users file if run twice (even with ``--dry-run``). |
355 |
|
356 |
The release fixes that bug (nothing else changed). |
357 |
|
358 |
|
359 |
Version 2.4.0 |
360 |
------------- |
361 |
|
362 |
*(Released Mon, 07 Mar 2011)* |
363 |
|
364 |
Final 2.4.0 release. Just a few small fixes: |
365 |
|
366 |
- Fixed RAPI node evacuate |
367 |
- Fixed the kvm-ifup script |
368 |
- Fixed internal error handling for special job cases |
369 |
- Updated man page to specify the escaping feature for options |
370 |
|
371 |
|
372 |
Version 2.4.0 rc3 |
373 |
----------------- |
374 |
|
375 |
*(Released Mon, 28 Feb 2011)* |
376 |
|
377 |
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible |
378 |
that this feature wiped the disks of the wrong instance, leading to loss |
379 |
of data. |
380 |
|
381 |
Other changes: |
382 |
|
383 |
- Fixed title of query field containing instance name |
384 |
- Expanded the glossary in the documentation |
385 |
- Fixed one unittest (internal issue) |
386 |
|
387 |
|
388 |
Version 2.4.0 rc2 |
389 |
----------------- |
390 |
|
391 |
*(Released Mon, 21 Feb 2011)* |
392 |
|
393 |
A number of bug fixes plus just a couple functionality changes. |
394 |
|
395 |
On the user-visible side, the ``gnt-* list`` command output has changed |
396 |
with respect to "special" field states. The current rc1 style of display |
397 |
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in |
398 |
the default output mode special fields states are displayed as follows: |
399 |
|
400 |
- Offline resource: ``*`` |
401 |
- Unavailable/not applicable: ``-`` |
402 |
- Data missing (RPC failure): ``?`` |
403 |
- Unknown field: ``??`` |
404 |
|
405 |
Another user-visible change is the addition of ``--force-join`` to |
406 |
``gnt-node add``. |
407 |
|
408 |
As for bug fixes: |
409 |
|
410 |
- ``tools/cluster-merge`` has seen many fixes and is now enabled again |
411 |
- Fixed regression in RAPI/instance reinstall where all parameters were |
412 |
required (instead of optional) |
413 |
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2 |
414 |
- Fixed iallocator usage (offline nodes were not considered offline) |
415 |
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes |
416 |
- Fixed hypervisor and OS parameter validation with respect to |
417 |
non-vm_capable nodes |
418 |
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly |
419 |
cosmetic) |
420 |
- Fixed ``tools/listrunner`` with respect to agent-based usage |
421 |
|
422 |
|
423 |
Version 2.4.0 rc1 |
424 |
----------------- |
425 |
|
426 |
*(Released Fri, 4 Feb 2011)* |
427 |
|
428 |
Many changes and fixes since the beta1 release. While there were some |
429 |
internal changes, the code has been mostly stabilised for the RC |
430 |
release. |
431 |
|
432 |
Note: the dumb allocator was removed in this release, as it was not kept |
433 |
up-to-date with the IAllocator protocol changes. It is recommended to |
434 |
use the ``hail`` command from the ganeti-htools package. |
435 |
|
436 |
Note: the 2.4 and up versions of Ganeti are not compatible with the |
437 |
0.2.x branch of ganeti-htools. You need to upgrade to |
438 |
ganeti-htools-0.3.0 (or later). |
439 |
|
440 |
Regressions fixed from 2.3 |
441 |
~~~~~~~~~~~~~~~~~~~~~~~~~~ |
442 |
|
443 |
- Fixed the ``gnt-cluster verify-disks`` command |
444 |
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to |
445 |
serially on nodes) |
446 |
- Fixed disk adoption breakage |
447 |
- Fixed wrong headers in instance listing for field aliases |
448 |
|
449 |
Other bugs fixed |
450 |
~~~~~~~~~~~~~~~~ |
451 |
|
452 |
- Fixed corner case in KVM handling of NICs |
453 |
- Fixed many cases of wrong handling of non-vm_capable nodes |
454 |
- Fixed a bug where a missing instance symlink was not possible to |
455 |
recreate with any ``gnt-*`` command (now ``gnt-instance |
456 |
activate-disks`` does it) |
457 |
- Fixed the volume group name as reported by ``gnt-cluster |
458 |
verify-disks`` |
459 |
- Increased timeouts for the import-export code, hopefully leading to |
460 |
fewer aborts due network or instance timeouts |
461 |
- Fixed bug in ``gnt-node list-storage`` |
462 |
- Fixed bug where not all daemons were started on cluster |
463 |
initialisation, but only at the first watcher run |
464 |
- Fixed many bugs in the OOB implementation |
465 |
- Fixed watcher behaviour in presence of instances with offline |
466 |
secondaries |
467 |
- Fixed instance list output for instances running on the wrong node |
468 |
- a few fixes to the cluster-merge tool, but it still cannot merge |
469 |
multi-node groups (currently it is not recommended to use this tool) |
470 |
|
471 |
|
472 |
Improvements |
473 |
~~~~~~~~~~~~ |
474 |
|
475 |
- Improved network configuration for the KVM hypervisor |
476 |
- Added e1000 as a supported NIC for Xen-HVM |
477 |
- Improved the lvmstrap tool to also be able to use partitions, as |
478 |
opposed to full disks |
479 |
- Improved speed of disk wiping (the cluster parameter |
480 |
``prealloc_wipe_disks``, so that it has a low impact on the total time |
481 |
of instance creations |
482 |
- Added documentation for the OS parameters |
483 |
- Changed ``gnt-instance deactivate-disks`` so that it can work if the |
484 |
hypervisor is not responding |
485 |
- Added display of blacklisted and hidden OS information in |
486 |
``gnt-cluster info`` |
487 |
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend, |
488 |
NIC and node parameters, which might create problems with currently |
489 |
invalid (but undetected) configuration files, but prevents validation |
490 |
failures when unrelated parameters are modified |
491 |
- Changed cluster initialisation to wait for the master daemon to become |
492 |
available |
493 |
- Expanded the RAPI interface: |
494 |
|
495 |
- Added config redistribution resource |
496 |
- Added activation/deactivation of instance disks |
497 |
- Added export of console information |
498 |
|
499 |
- Implemented log file reopening on SIGHUP, which allows using |
500 |
logrotate(8) for the Ganeti log files |
501 |
- Added a basic OOB helper script as an example |
502 |
|
503 |
|
504 |
Version 2.4.0 beta1 |
505 |
------------------- |
506 |
|
507 |
*(Released Fri, 14 Jan 2011)* |
508 |
|
509 |
User-visible |
510 |
~~~~~~~~~~~~ |
511 |
|
512 |
- Fixed timezone issues when formatting timestamps |
513 |
- Added support for node groups, available via ``gnt-group`` and other |
514 |
commands |
515 |
- Added out-of-band framework and management, see :doc:`design |
516 |
document <design-oob>` |
517 |
- Removed support for roman numbers from ``gnt-node list`` and |
518 |
``gnt-instance list``. |
519 |
- Allowed modification of master network interface via ``gnt-cluster |
520 |
modify --master-netdev`` |
521 |
- Accept offline secondaries while shutting down instance disks |
522 |
- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors |
523 |
- Added support for multiple LVM volume groups |
524 |
- Avoid sorting nodes for ``gnt-node list`` if specific nodes are |
525 |
requested |
526 |
- Added commands to list available fields: |
527 |
|
528 |
- ``gnt-node list-fields`` |
529 |
- ``gnt-group list-fields`` |
530 |
- ``gnt-instance list-fields`` |
531 |
|
532 |
- Updated documentation and man pages |
533 |
|
534 |
Integration |
535 |
~~~~~~~~~~~ |
536 |
|
537 |
- Moved ``rapi_users`` file into separate directory, now named |
538 |
``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a |
539 |
symlink |
540 |
- Added new tool for running commands on many machines, |
541 |
``tools/ganeti-listrunner`` |
542 |
- Implemented more verbose result in ``OpInstanceConsole`` opcode, also |
543 |
improving the ``gnt-instance console`` output |
544 |
- Allowed customisation of disk index separator at ``configure`` time |
545 |
- Export node group allocation policy to :doc:`iallocator <iallocator>` |
546 |
- Added support for non-partitioned md disks in ``lvmstrap`` |
547 |
- Added script to gracefully power off KVM instances |
548 |
- Split ``utils`` module into smaller parts |
549 |
- Changed query operations to return more detailed information, e.g. |
550 |
whether an information is unavailable due to an offline node. To use |
551 |
this new functionality, the LUXI call ``Query`` must be used. Field |
552 |
information is now stored by the master daemon and can be retrieved |
553 |
using ``QueryFields``. Instances, nodes and groups can also be queried |
554 |
using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet |
555 |
exposed via RAPI). The following commands make use of this |
556 |
infrastructure change: |
557 |
|
558 |
- ``gnt-group list`` |
559 |
- ``gnt-group list-fields`` |
560 |
- ``gnt-node list`` |
561 |
- ``gnt-node list-fields`` |
562 |
- ``gnt-instance list`` |
563 |
- ``gnt-instance list-fields`` |
564 |
- ``gnt-debug locks`` |
565 |
|
566 |
Remote API |
567 |
~~~~~~~~~~ |
568 |
|
569 |
- New RAPI resources (see :doc:`rapi`): |
570 |
|
571 |
- ``/2/modify`` |
572 |
- ``/2/groups`` |
573 |
- ``/2/groups/[group_name]`` |
574 |
- ``/2/groups/[group_name]/assign-nodes`` |
575 |
- ``/2/groups/[group_name]/modify`` |
576 |
- ``/2/groups/[group_name]/rename`` |
577 |
- ``/2/instances/[instance_name]/disk/[disk_index]/grow`` |
578 |
|
579 |
- RAPI changes: |
580 |
|
581 |
- Implemented ``no_install`` for instance creation |
582 |
- Implemented OS parameters for instance reinstallation, allowing |
583 |
use of special settings on reinstallation (e.g. for preserving data) |
584 |
|
585 |
Misc |
586 |
~~~~ |
587 |
|
588 |

782 |
Version 2.2.0 rc0 |
783 |
----------------- |
784 |
|
785 |
*(Released Fri, 30 Jul 2010)* |
786 |
|
787 |
Important change: the internal RPC mechanism between Ganeti nodes has |
788 |
changed from using a home-grown http library (based on the Python base |
789 |
libraries) to use the PycURL library. This requires that PycURL is |
790 |
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked |
791 |
against GnuTLS by default. cURL's support for GnuTLS had known issues |
792 |
before cURL 7.21.0 and we recommend using the latest cURL release or |
793 |
linking against OpenSSL. Most other distributions already link PycURL |
794 |
and cURL against OpenSSL. The command:: |
795 |
|
796 |
python -c 'import pycurl; print pycurl.version' |
797 |
|
798 |
can be used to determine the libraries PycURL and cURL are linked |
799 |
against. |
800 |
|
801 |
Other significant changes: |
802 |
|
803 |
- Rewrote much of the internals of the job queue, in order to achieve |
804 |
better parallelism; this decouples job query operations from the job |
805 |
processing, and it should allow much nicer behaviour of the master |
806 |
daemon under load, and it also has uncovered some long-standing bugs |
807 |
related to the job serialisation (now fixed) |
808 |
- Added a default iallocator setting to the cluster parameters, |
809 |
eliminating the need to always pass nodes or an iallocator for |
810 |
operations that require selection of new node(s) |
811 |
- Added experimental support for the LXC virtualization method |
812 |
- Added support for OS parameters, which allows the installation of |
813 |
instances to pass parameter to OS scripts in order to customise the |
814 |
instance |
815 |
- Added a hypervisor parameter controlling the migration type (live or |
816 |
non-live), since hypervisors have various levels of reliability; this |
817 |
has renamed the 'live' parameter to 'mode' |
818 |
- Added a cluster parameter ``reserved_lvs`` that denotes reserved |
819 |
logical volumes, meaning that cluster verify will ignore them and not |
820 |
flag their presence as errors |
821 |
- The watcher will now reset the error count for failed instances after |
822 |
8 hours, thus allowing self-healing if the problem that caused the |
823 |
instances to be down/fail to start has cleared in the meantime |
824 |
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti |
825 |
check for, and warn, if the drbd module parameter ``usermode_helper`` |
826 |
is not consistent with the cluster-wide setting; this is needed to |
827 |
make diagnose easier of failed drbd creations |
828 |
- Started adding base IPv6 support, but this is not yet |
829 |
enabled/available for use |
830 |
- Rename operations (cluster, instance) will now return the new name, |
831 |
which is especially useful if a short name was passed in |
832 |
- Added support for instance migration in RAPI |
833 |
- Added a tool to pre-configure nodes for the SSH setup, before joining |
834 |
them to the cluster; this will allow in the future a simplified model |
835 |
for node joining (but not yet fully enabled in 2.2); this needs the |
836 |
paramiko python library |
837 |
- Fixed handling of name-resolving errors |
838 |
- Fixed consistency of job results on the error path |
839 |
- Fixed master-failover race condition when executed multiple times in |
840 |
sequence |
841 |
- Fixed many bugs related to the job queue (mostly introduced during the |
842 |
2.2 development cycle, so not all are impacting 2.1) |
843 |
- Fixed instance migration with missing disk symlinks |
844 |
- Fixed handling of unknown jobs in ``gnt-job archive`` |
845 |
- And many other small fixes/improvements |
846 |
|
847 |
Internal changes: |
848 |
|
849 |
- Enhanced both the unittest and the QA coverage |
850 |
- Switched the opcode validation to a generic model, and extended the |
851 |
validation to all opcode parameters |
852 |
- Changed more parts of the code that write shell scripts to use the |
853 |
same class for this |
854 |
- Switched the master daemon to use the asyncore library for the Luxi |
855 |
server endpoint |
856 |
|
857 |
|
858 |
Version 2.2.0 beta0 |
859 |
------------------- |
860 |
|
861 |
*(Released Thu, 17 Jun 2010)* |
862 |
|
863 |
- Added tool (``move-instance``) and infrastructure to move instances |
864 |
between separate clusters (see :doc:`separate documentation |
865 |
<move-instance>` and :doc:`design document <design-2.2>`) |
866 |
- Added per-request RPC timeout |
867 |
- RAPI now requires a Content-Type header for requests with a body (e.g. |
868 |
``PUT`` or ``POST``) which must be set to ``application/json`` (see |
869 |
:rfc:`2616` (HTTP/1.1), section 7.2.1) |
870 |
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not |
871 |
reachable |
872 |
- Implemented initial support for running Ganeti daemons as separate |
873 |
users, see configure-time flags ``--with-user-prefix`` and |
874 |
``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this |
875 |
time) |
876 |
- Instances can be removed after export (``gnt-backup export |
877 |
--remove-instance``) |
878 |
- Self-signed certificates generated by Ganeti now use a 2048 bit RSA |
879 |
key (instead of 1024 bit) |
880 |
- Added new cluster configuration file for cluster domain secret |
881 |
- Import/export now use SSL instead of SSH |
882 |
- Added support for showing estimated time when exporting an instance, |
883 |
see the ``ganeti-os-interface(7)`` manpage and look for |
884 |
``EXP_SIZE_FD`` |
885 |
|
886 |
|
887 |
Version 2.1.8 |
888 |
------------- |
889 |

Version 2.1.7 |
902 |
------------- |
903 |
|
904 |
*(Released Tue, 24 Aug 2010)* |
905 |
|
906 |
Bugfixes only: |
907 |
- Don't ignore secondary node silently on non-mirrored disk templates |
908 |
(issue 113) |
909 |
- Fix --master-netdev arg name in gnt-cluster(8) (issue 114) |

911 |
- Properly document the usb_mouse parameter |
912 |
- Fix path in ganeti-rapi(8) (issue 116) |
913 |
- Adjust error message when the ganeti user's .ssh directory is |
914 |
missing |
915 |
- Add same-node-check when changing the disk template to drbd |
916 |
|
917 |
|
918 |
Version 2.1.6 |
919 |
------------- |
920 |
|
921 |
*(Released Fri, 16 Jul 2010)* |
922 |
|
923 |
Bugfixes only: |
924 |
- Add an option to only select some reboot types during qa/burnin. |
925 |
(on some hypervisors consequent reboots are not supported) |
926 |
- Fix infrequent race condition in master failover. Sometimes the old |
927 |
master ip address would be still detected as up for a short time |
928 |
after it was removed, causing failover to fail. |
929 |
- Decrease mlockall warnings when the ctypes module is missing. On |
930 |
Python 2.4 we support running even if no ctypes module is installed, |
931 |
but we were too verbose about this issue. |
932 |
- Fix building on old distributions, on which man doesn't have a |
933 |
--warnings option. |
934 |
- Fix RAPI not to ignore the MAC address on instance creation |
935 |
- Implement the old instance creation format in the RAPI client. |

A small bugfix release: |
944 |
- Fix disk adoption: broken by strict --disk option checking in 2.1.4 |
945 |
- Fix batch-create: broken in the whole 2.1 series due to a lookup on |
946 |
a non-existing option |
947 |

948 |
- Improve pylint 0.21 compatibility and warnings with Python 2.6 |
949 |
- Fix modify node storage with non-FQDN arguments |
950 |

961 |
A small bugfix release: |
962 |
|
963 |
- Fix live migration of KVM instances started with older Ganeti |
964 |
versions which had fewer hypervisor parameters |
965 |
- Fix gnt-instance grow-disk on down instances |
966 |
- Fix an error-reporting bug during instance migration |
967 |
- Better checking of the ``--net`` and ``--disk`` values, to avoid |
968 |

970 |
users |
971 |
- Fix bug triggered by different API version os-es on different nodes |
972 |
- Fix a bug in instance startup with custom hvparams: OS level |
973 |
parameters would fail to be applied. |
974 |
- Fix the RAPI client under Python 2.6 (but more work is needed to |
975 |
make it work completely well with OpenSSL) |
976 |
- Fix handling of errors when resolving names from DNS |
977 |
|
978 |

Version 2.1.3 |
980 |
------------- |
981 |
|
982 |
*(Released Thu, 3 Jun 2010)* |
983 |
|
984 |
A medium sized development cycle. Some new features, and some |
985 |
fixes/small improvements/cleanups. |
986 |
|
987 |
Significant features |
988 |
~~~~~~~~~~~~~~~~~~~~ |
989 |
|
990 |
The node deamon now tries to mlock itself into memory, unless the |
991 |
``--no-mlock`` flag is passed. It also doesn't fail if it can't write |
992 |
its logs, and falls back to console logging. This allows emergency |
993 |
features such as ``gnt-node powercycle`` to work even in the event of a |
994 |
broken node disk (tested offlining the disk hosting the node's |
995 |
filesystem and dropping its memory caches; don't try this at home) |
996 |
|
997 |
KVM: add vhost-net acceleration support. It can be tested with a new |
998 |
enough version of the kernel and of qemu-kvm. |
999 |
|
1000 |
KVM: Add instance chrooting feature. If you use privilege dropping for |
1001 |
your VMs you can also now force them to chroot to an empty directory, |
1002 |
before starting the emulated guest. |
1003 |
|
1004 |
KVM: Add maximum migration bandwith and maximum downtime tweaking |
1005 |
support (requires a new-enough version of qemu-kvm). |
1006 |
|
1007 |
Cluster verify will now warn if the master node doesn't have the master |
1008 |
ip configured on it. |
1009 |
|
1010 |
Add a new (incompatible) instance creation request format to RAPI which |
1011 |
supports all parameters (previously only a subset was supported, and it |
1012 |
wasn't possible to extend the old format to accomodate all the new |
1013 |
features. The old format is still supported, and a client can check for |
1014 |
this feature, before using it, by checking for its presence in the |
1015 |
``features`` RAPI resource. |
1016 |
|
1017 |
Now with ancient latin support. Try it passing the ``--roman`` option to |
1018 |
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list`` |
1019 |
(requires the python-roman module to be installed, in order to work). |
1020 |
|
1021 |
Other changes |
1022 |
~~~~~~~~~~~~~ |
1023 |
|
1024 |
As usual many internal code refactorings, documentation updates, and |
1025 |
such. Among others: |
1026 |
|
1027 |
- Lots of improvements and cleanups to the experimental Remote API |
1028 |
(RAPI) client library. |
1029 |
- A new unit test suite for the core daemon libraries. |
1030 |
- A fix to creating missing directories makes sure the umask is not |
1031 |
applied anymore. This enforces the same directory permissions |
1032 |
everywhere. |
1033 |
- Better handling terminating daemons with ctrl+c (used when running |
1034 |
them in debugging mode). |
1035 |
- Fix a race condition in live migrating a KVM instance, when stat() |
1036 |
on the old proc status file returned EINVAL, which is an unexpected |
1037 |
value. |
1038 |
- Fixed manpage checking with newer man and utf-8 charachters. But now |
1039 |
you need the en_US.UTF-8 locale enabled to build Ganeti from git. |
1040 |
|
1041 |
|
1042 |
Version 2.1.2.1 |
1043 |
--------------- |
1044 |
|
1045 |
*(Released Fri, 7 May 2010)* |
1046 |
|
1047 |
Fix a bug which prevented untagged KVM instances from starting. |
1048 |
|
1049 |
|
1050 |
Version 2.1.2 |
1051 |
------------- |
1052 |
|
1053 |
*(Released Fri, 7 May 2010)* |
1054 |
|
1055 |
Another release with a long development cycle, during which many |
1056 |
different features were added. |
1057 |
|
1058 |
Significant features |
1059 |
~~~~~~~~~~~~~~~~~~~~ |
1060 |
|
1061 |
The KVM hypervisor now can run the individual instances as non-root, to |
1062 |
reduce the impact of a VM being hijacked due to bugs in the |
1063 |
hypervisor. It is possible to run all instances as a single (non-root) |
1064 |
user, to manually specify a user for each instance, or to dynamically |
1065 |
allocate a user out of a cluster-wide pool to each instance, with the |
1066 |
guarantee that no two instances will run under the same user ID on any |
1067 |
given node. |
1068 |
|
1069 |
An experimental RAPI client library, that can be used standalone |
1070 |
(without the other Ganeti libraries), is provided in the source tree as |
1071 |
``lib/rapi/client.py``. Note this client might change its interface in |
1072 |
the future, as we iterate on its capabilities. |
1073 |
|
1074 |
A new command, ``gnt-cluster renew-crypto`` has been added to easily |
1075 |
replace the cluster's certificates and crypto keys. This might help in |
1076 |
case they have been compromised, or have simply expired. |
1077 |
|
1078 |
A new disk option for instance creation has been added that allows one |
1079 |
to "adopt" currently existing logical volumes, with data |
1080 |
preservation. This should allow easier migration to Ganeti from |
1081 |
unmanaged (or managed via other software) instances. |
1082 |
|
1083 |
Another disk improvement is the possibility to convert between redundant |
1084 |
(DRBD) and plain (LVM) disk configuration for an instance. This should |
1085 |
allow better scalability (starting with one node and growing the |
1086 |
cluster, or shrinking a two-node cluster to one node). |
1087 |
|
1088 |
A new feature that could help with automated node failovers has been |
1089 |
implemented: if a node sees itself as offline (by querying the master |
1090 |
candidates), it will try to shutdown (hard) all instances and any active |
1091 |
DRBD devices. This reduces the risk of duplicate instances if an |
1092 |
external script automatically failovers the instances on such nodes. To |
1093 |
enable this, the cluster parameter ``maintain_node_health`` should be |
1094 |
enabled; in the future this option (per the name) will enable other |
1095 |
automatic maintenance features. |
1096 |
|
1097 |
Instance export/import now will reuse the original instance |
1098 |
specifications for all parameters; that means exporting an instance, |
1099 |
deleting it and the importing it back should give an almost identical |
1100 |
instance. Note that the default import behaviour has changed from |
1101 |
before, where it created only one NIC; now it recreates the original |
1102 |
number of NICs. |
1103 |
|
1104 |
Cluster verify has added a few new checks: SSL certificates validity, |
1105 |
/etc/hosts consistency across the cluster, etc. |
1106 |
|
1107 |
Other changes |
1108 |
~~~~~~~~~~~~~ |
1109 |
|
1110 |
As usual, many internal changes were done, documentation fixes, |
1111 |
etc. Among others: |
1112 |
|
1113 |
- Fixed cluster initialization with disabled cluster storage (regression |
1114 |
introduced in 2.1.1) |
1115 |
- File-based storage supports growing the disks |
1116 |
- Fixed behaviour of node role changes |
1117 |
- Fixed cluster verify for some corner cases, plus a general rewrite of |
1118 |
cluster verify to allow future extension with more checks |
1119 |
- Fixed log spamming by watcher and node daemon (regression introduced |
1120 |
in 2.1.1) |
1121 |
- Fixed possible validation issues when changing the list of enabled |
1122 |
hypervisors |
1123 |
- Fixed cleanup of /etc/hosts during node removal |
1124 |
- Fixed RAPI response for invalid methods |
1125 |
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon |
1126 |
- Multiple small improvements to the KVM hypervisor (VNC usage, booting |
1127 |
from ide disks, etc.) |
1128 |
- Allow OS changes without re-installation (to record a changed OS |
1129 |
outside of Ganeti, or to allow OS renames) |
1130 |
- Allow instance creation without OS installation (useful for example if |
1131 |
the OS will be installed manually, or restored from a backup not in |
1132 |
Ganeti format) |
1133 |
- Implemented option to make cluster ``copyfile`` use the replication |
1134 |
network |
1135 |
- Added list of enabled hypervisors to ssconf (possibly useful for |
1136 |
external scripts) |
1137 |
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from |
1138 |
1.2 clusters |
1139 |
- A partial form of node re-IP is possible via node readd, which now |
1140 |
allows changed node primary IP |
1141 |
- Command line utilities now show an informational message if the job is |
1142 |
waiting for a lock |
1143 |
- The logs of the master daemon now show the PID/UID/GID of the |
1144 |
connected client |
1145 |
|
1146 |
|
1147 |
Version 2.1.1 |
1148 |
------------- |
1149 |
|
1150 |
*(Released Fri, 12 Mar 2010)* |
1151 |
|
1152 |
During the 2.1.0 long release candidate cycle, a lot of improvements and |
1153 |
changes have accumulated with were released later as 2.1.1. |
1154 |
|
1155 |
Major changes |
1156 |
~~~~~~~~~~~~~ |
1157 |
|
1158 |
The node evacuate command (``gnt-node evacuate``) was significantly |
1159 |
rewritten, and as such the IAllocator protocol was changed - a new |
1160 |
request type has been added. This unfortunate change during a stable |
1161 |
series is designed to improve performance of node evacuations; on |
1162 |
clusters with more than about five nodes and which are well-balanced, |
1163 |
evacuation should proceed in parallel for all instances of the node |
1164 |
being evacuated. As such, any existing IAllocator scripts need to be |
1165 |
updated, otherwise the above command will fail due to the unknown |
1166 |
request. The provided "dumb" allocator has not been updated; but the |
1167 |
ganeti-htools package supports the new protocol since version 0.2.4. |
1168 |
|
1169 |
Another important change is increased validation of node and instance |
1170 |
names. This might create problems in special cases, if invalid host |
1171 |
names are being used. |
1172 |
|
1173 |
Also, a new layer of hypervisor parameters has been added, that sits at |
1174 |
OS level between the cluster defaults and the instance ones. This allows |
1175 |
customisation of virtualization parameters depending on the installed |
1176 |
OS. For example instances with OS 'X' may have a different KVM kernel |
1177 |
(or any other parameter) than the cluster defaults. This is intended to |
1178 |
help managing a multiple OSes on the same cluster, without manual |
1179 |
modification of each instance's parameters. |
1180 |
|
1181 |
A tool for merging clusters, ``cluster-merge``, has been added in the |
1182 |
tools sub-directory. |
1183 |
|
1184 |
Bug fixes |
1185 |
~~~~~~~~~ |
1186 |
|
1187 |
- Improved the int/float conversions that should make the code more |
1188 |
robust in face of errors from the node daemons |
1189 |
- Fixed the remove node code in case of internal configuration errors |
1190 |
- Fixed the node daemon behaviour in face of inconsistent queue |
1191 |
directory (e.g. read-only file-system where we can't open the files |
1192 |
read-write, etc.) |
1193 |
- Fixed the behaviour of gnt-node modify for master candidate demotion; |
1194 |
now it either aborts cleanly or, if given the new "auto_promote" |
1195 |
parameter, will automatically promote other nodes as needed |
1196 |
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would |
1197 |
completely prevent Ganeti from working |
1198 |
- Fixed bug for instance export when not all disks were successfully |
1199 |
exported |
1200 |
- Fixed behaviour of node add when the new node is slow in starting up |
1201 |
the node daemon |
1202 |
- Fixed handling of signals in the LUXI client, which should improve |
1203 |
behaviour of command-line scripts |
1204 |
- Added checks for invalid node/instance names in the configuration (now |
1205 |
flagged during cluster verify) |
1206 |
- Fixed watcher behaviour for disk activation errors |
1207 |
- Fixed two potentially endless loops in http library, which led to the |
1208 |
RAPI daemon hanging and consuming 100% CPU in some cases |
1209 |
- Fixed bug in RAPI daemon related to hashed passwords |
1210 |
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM |
1211 |
instances |
1212 |
- Enhanced compatibility with non-Debian OSes, but not using absolute |
1213 |
path in some commands and allowing customisation of the ssh |
1214 |
configuration directory |
1215 |
- Fixed possible future issue with new Python versions by abiding to the |
1216 |
proper use of ``__slots__`` attribute on classes |
1217 |
- Added checks that should prevent directory traversal attacks |
1218 |
- Many documentation fixes based on feedback from users |
1219 |
|
1220 |
New features |
1221 |
~~~~~~~~~~~~ |
1222 |
|
1223 |
- Added an "early_release" more for instance replace disks and node |
1224 |
evacuate, where we release locks earlier and thus allow higher |
1225 |
parallelism within the cluster |
1226 |
- Added watcher hooks, intended to allow the watcher to restart other |
1227 |
daemons (e.g. from the ganeti-nbma project), but they can be used of |
1228 |
course for any other purpose |
1229 |
- Added a compile-time disable for DRBD barriers, to increase |
1230 |
performance if the administrator trusts the power supply or the |
1231 |
storage system to not lose writes |
1232 |
- Added the option of using syslog for logging instead of, or in |
1233 |
addition to, Ganeti's own log files |
1234 |
- Removed boot restriction for paravirtual NICs for KVM, recent versions |
1235 |
can indeed boot from a paravirtual NIC |
1236 |
- Added a generic debug level for many operations; while this is not |
1237 |
used widely yet, it allows one to pass the debug value all the way to |
1238 |
the OS scripts |
1239 |
- Enhanced the hooks environment for instance moves (failovers, |
1240 |
migrations) where the primary/secondary nodes changed during the |
1241 |
operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars |
1242 |
- Enhanced data validations for many user-supplied values; one important |
1243 |
item is the restrictions imposed on instance and node names, which |
1244 |
might reject some (invalid) host names |
1245 |
- Add a configure-time option to disable file-based storage, if it's not |
1246 |
needed; this allows greater security separation between the master |
1247 |
node and the other nodes from the point of view of the inter-node RPC |
1248 |
protocol |
1249 |
- Added user notification in interactive tools if job is waiting in the |
1250 |
job queue or trying to acquire locks |
1251 |
- Added log messages when a job is waiting for locks |
1252 |
- Added filtering by node tags in instance operations which admit |
1253 |
multiple instances (start, stop, reboot, reinstall) |
1254 |
- Added a new tool for cluster mergers, ``cluster-merge`` |
1255 |
- Parameters from command line which are of the form ``a=b,c=d`` can now |
1256 |
use backslash escapes to pass in values which contain commas, |
1257 |
e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value |
1258 |
``b,c`` |
1259 |
- For KVM, the instance name is the first parameter passed to KVM, so |
1260 |
that it's more visible in the process list |
1261 |
|
1262 |
|
1263 |
Version 2.1.0 |
1264 |
------------- |
1265 |
|
1266 |
*(Released Tue, 2 Mar 2010)* |
1267 |
|
1268 |
Ganeti 2.1 brings many improvements with it. Major changes: |
1269 |
|
1270 |
- Added infrastructure to ease automated disk repairs |
1271 |
- Added new daemon to export configuration data in a cheaper way than |
1272 |
using the remote API |
1273 |
- Instance NICs can now be routed instead of being associated with a |
1274 |
networking bridge |
1275 |
- Improved job locking logic to reduce impact of jobs acquiring multiple |
1276 |
locks waiting for other long-running jobs |
1277 |
|
1278 |
In-depth implementation details can be found in the Ganeti 2.1 design |
1279 |
document. |
1280 |

1281 |
Details |
1282 |
~~~~~~~ |
1283 |
|

1312 |
(``ssconf_master_candidates_ips``), node primary IP address |
1313 |
(``ssconf_node_primary_ips``) and node secondary IP address |
1314 |
(``ssconf_node_secondary_ips``) |
1315 |

(``rapi_users``) |
1336 |
- Added option to specify maximum timeout on instance shutdown |
1337 |
- Added ``--no-ssh-init`` option to ``gnt-cluster init`` |
1338 |
- Added new helper script to start and stop Ganeti daemons |
1339 |
(``daemon-util``), with the intent to reduce the work necessary to |
1340 |
adjust Ganeti for non-Debian distributions and to start/stop daemons |
1341 |
from one place |
1342 |
- Added more unittests |
1343 |
- Fixed critical bug in ganeti-masterd startup |
1344 |
- Removed the configure-time ``kvm-migration-port`` parameter, this is |
1345 |
now customisable at the cluster level for both the KVM and Xen |

|
1378 |
*(Released Thu, 17 Dec 2009)* |
1379 |

1381 |
allows local and remote execution of arbitrary executables |
1382 |
- Fix failure of gnt-node list during instance removal |
1383 |
- Ship the RAPI documentation in the archive |
1384 |
|

Version 2.0.4 |
1387 |
------------- |
1388 |
|

1399 |
Debian) |
1400 |
- Fixed handling of drained nodes in the iallocator framework |
1401 |
- Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug |
1402 |
#528618) |
1403 |
- Fixed error related to invalid job IDs in job polling |
1404 |
- Fixed job/opcode persistence on unclean master shutdown |
1405 |
- Fixed handling of partial job processing after unclean master |
1406 |

1407 |
- Fixed error reporting from LUs, previously all errors were converted |
1408 |
into execution errors |
1409 |
- Fixed error reporting from burnin |
1410 |
- Decreased significantly the memory usage of the job queue |
1411 |
- Optimised slightly multi-job submission |
1412 |
- Optimised slightly opcode loading |
1413 |
- Backported the multi-job submit framework from the development |
1414 |
branch; multi-instance start and stop should be faster |
1415 |
- Added script to clean archived jobs after 21 days; this will reduce |
1416 |
the size of the queue directory |
1417 |
- Added some extra checks in disk size tracking |
1418 |
- Added an example ethers hook script |
1419 |

1430 |
|
1431 |
Version 2.0.3 |
1432 |
------------- |
1433 |
|
1434 |
*(Released Fri, 7 Aug 2009)* |
1435 |
|
1436 |
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
1437 |
to allow using the pre-2.0.2 behaviour in activation, if any existing |
1438 |
instances have mismatched disk sizes in the configuration |
1439 |
- Added ``gnt-cluster repair-disk-sizes`` command to check and update |
1440 |
any configuration mismatches for disk sizes |
1441 |
- Added ``gnt-master cluste-failover --no-voting`` to allow master |
1442 |
failover to work on two-node clusters |
1443 |
- Fixed the ``--net`` option of ``gnt-backup import``, which was |
1444 |
unusable |
1445 |
- Fixed detection of OS script errors in ``gnt-backup export`` |
1446 |
- Fixed exit code of ``gnt-backup export`` |
1447 |
|
1448 |
|
1449 |
Version 2.0.2 |
1450 |
------------- |
1451 |
|
1452 |
*(Released Fri, 17 Jul 2009)* |
1453 |
|
1454 |
- Added experimental support for stripped logical volumes; this should |
1455 |
enhance performance but comes with a higher complexity in the block |
1456 |
device handling; stripping is only enabled when passing |
1457 |
``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
1458 |
affected even in the non-stripped mode |
1459 |
- Improved resiliency against transient failures at the end of DRBD |
1460 |
resyncs, and in general of DRBD resync checks |
1461 |
- Fixed a couple of issues with exports and snapshot errors |
1462 |
- Fixed a couple of issues in instance listing |
1463 |
- Added display of the disk size in ``gnt-instance info`` |
1464 |
- Fixed checking for valid OSes in instance creation |
1465 |
- Fixed handling of the "vcpus" parameter in instance listing and in |
1466 |
general of invalid parameters |
1467 |
- Fixed http server library, and thus RAPI, to handle invalid |
1468 |
username/password combinations correctly; this means that now they |
1469 |
report unauthorized for queries too, not only for modifications, |
1470 |
allowing earlier detect of configuration problems |
1471 |
- Added a new "role" node list field, equivalent to the master/master |
1472 |
candidate/drained/offline flags combinations |
1473 |
- Fixed cluster modify and changes of candidate pool size |
1474 |
- Fixed cluster verify error messages for wrong files on regular nodes |
1475 |
- Fixed a couple of issues with node demotion from master candidate role |
1476 |
- Fixed node readd issues |
1477 |
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
1478 |
- Added a new ``--no-voting`` option for masterfailover to fix failover |
1479 |
on two-nodes clusters when the former master node is unreachable |
1480 |
- Added instance reinstall over RAPI |
1481 |
|
1482 |
|
1483 |
Version 2.0.1 |
1484 |
------------- |
1485 |
|
1486 |
*(Released Tue, 16 Jun 2009)* |
1487 |
|
1488 |
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
1489 |
allow re-adding the start in single-user option (regression from 1.2) |
1490 |
- the watcher writes the instance status to a file, to allow monitoring |
1491 |
to report the instance status (from the master) based on cached |
1492 |
results of the watcher's queries; while this can get stale if the |
1493 |
watcher is being locked due to other work on the cluster, this is |
1494 |
still an improvement |
1495 |
- the watcher now also restarts the node daemon and the rapi daemon if |
1496 |
they died |
1497 |
- fixed the watcher to handle full and drained queue cases |
1498 |
- hooks export more instance data in the environment, which helps if |
1499 |
hook scripts need to take action based on the instance's properties |
1500 |
(no longer need to query back into ganeti) |
1501 |
- instance failovers when the instance is stopped do not check for free |
1502 |
RAM, so that failing over a stopped instance is possible in low memory |
1503 |
situations |
1504 |
- rapi uses queries for tags instead of jobs (for less job traffic), and |
1505 |
for cluster tags it won't talk to masterd at all but read them from |
1506 |
ssconf |
1507 |
- a couple of error handling fixes in RAPI |
1508 |
- drbd handling: improved the error handling of inconsistent disks after |
1509 |
resync to reduce the frequency of "there are some degraded disks for |
1510 |
this instance" messages |
1511 |
- fixed a bug in live migration when DRBD doesn't want to reconnect (the |
1512 |
error handling path called a wrong function name) |
1513 |
|
1514 |
|
1515 |
Version 2.0.0 |
1516 |
------------- |
1517 |
|
1518 |
*(Released Wed, 27 May 2009)* |
1519 |
|
1520 |
- no changes from rc5 |
1521 |
|
1522 |

1523 |
Version 2.0 rc5 |
1524 |
--------------- |
1525 |
|
1526 |
*(Released Wed, 20 May 2009)* |
1527 |
|
1528 |
- fix a couple of bugs (validation, argument checks) |
1529 |
- fix ``gnt-cluster getmaster`` on non-master nodes (regression) |
1530 |
- some small improvements to RAPI and IAllocator |
1531 |
- make watcher automatically start the master daemon if down |
1532 |
|
1533 |
|
1534 |
Version 2.0 rc4 |
1535 |
--------------- |
1536 |
|
1537 |
*(Released Mon, 27 Apr 2009)* |
1538 |
|
1539 |
- change the OS list to not require locks; this helps with big clusters |
1540 |
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the |
1541 |
volume group is broken |
1542 |
- ``gnt-instance info``, without any arguments, doesn't run for all |
1543 |
instances anymore; either pass ``--all`` or pass the desired |
1544 |
instances; this helps against mistakes on big clusters where listing |
1545 |
the information for all instances takes a long time |
1546 |
- miscellaneous doc and man pages fixes |
1547 |
|
1548 |
|
1549 |
Version 2.0 rc3 |
1550 |
--------------- |
1551 |
|
1552 |
*(Released Wed, 8 Apr 2009)* |
1553 |
|
1554 |
- Change the internal locking model of some ``gnt-node`` commands, in |
1555 |
order to reduce contention (and blocking of master daemon) when |
1556 |
batching many creation/reinstall jobs |
1557 |
- Fixes to Xen soft reboot |
1558 |
- No longer build documentation at build time, instead distribute it in |
1559 |
the archive, in order to reduce the need for the whole docbook/rst |
1560 |
toolchains |
1561 |
|
1562 |
|
1563 |
Version 2.0 rc2 |
1564 |
--------------- |
1565 |
|
1566 |
*(Released Fri, 27 Mar 2009)* |
1567 |
|
1568 |
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0 |
1569 |
- Fix watcher startup sequence, improves the behaviour of busy clusters |
1570 |
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance |
1571 |
replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC |
1572 |
bind address and other places |
1573 |
- Some documentation fixes and updates |
1574 |
|
1575 |
|
1576 |
Version 2.0 rc1 |
1577 |
--------------- |
1578 |
|
1579 |
*(Released Mon, 2 Mar 2009)* |
1580 |
|
1581 |
- More documentation updates, now all docs should be more-or-less |
1582 |
up-to-date |
1583 |
- A couple of small fixes (mixed hypervisor clusters, offline nodes, |
1584 |
etc.) |
1585 |
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM |
1586 |
and KVM) |
1587 |
- Fix an issue related to $libdir/run/ganeti and cluster creation |
1588 |
|
1589 |
|
1590 |
Version 2.0 beta2 |
1591 |
----------------- |
1592 |
|
1593 |
*(Released Thu, 19 Feb 2009)* |
1594 |
|
1595 |
- Xen PVM and KVM have switched the default value for the instance root |
1596 |
disk to the first partition on the first drive, instead of the whole |
1597 |
drive; this means that the OS installation scripts must be changed |
1598 |
accordingly |
1599 |
- Man pages have been updated |
1600 |
- RAPI has been switched by default to HTTPS, and the exported functions |
1601 |
should all work correctly |
1602 |
- RAPI v1 has been removed |
1603 |
- Many improvements to the KVM hypervisor |
1604 |
- Block device errors are now better reported |
1605 |
- Many other bugfixes and small improvements |
1606 |
|
1607 |
|
1608 |
Version 2.0 beta1 |
1609 |
----------------- |
1610 |
|
1611 |
*(Released Mon, 26 Jan 2009)* |
1612 |
|
1613 |
- Version 2 is a general rewrite of the code and therefore the |
1614 |
differences are too many to list, see the design document for 2.0 in |
1615 |
the ``doc/`` subdirectory for more details |
1616 |
- In this beta version there is not yet a migration path from 1.2 (there |
1617 |
will be one in the final 2.0 release) |
1618 |
- A few significant changes are: |
1619 |
|
1620 |
- all commands are executed by a daemon (``ganeti-masterd``) and the |
1621 |
various ``gnt-*`` commands are just front-ends to it |
1622 |
- all the commands are entered into, and executed from a job queue, |
1623 |
see the ``gnt-job(8)`` manpage |
1624 |
- the RAPI daemon supports read-write operations, secured by basic |
1625 |
HTTP authentication on top of HTTPS |
1626 |
- DRBD version 0.7 support has been removed, DRBD 8 is the only |
1627 |
supported version (when migrating from Ganeti 1.2 to 2.0, you need |
1628 |
to migrate to DRBD 8 first while still running Ganeti 1.2) |
1629 |
- DRBD devices are using statically allocated minor numbers, which |
1630 |
will be assigned to existing instances during the migration process |
1631 |
- there is support for both Xen PVM and Xen HVM instances running on |
1632 |
the same cluster |
1633 |
- KVM virtualization is supported too |
1634 |
- file-based storage has been implemented, which means that it is |
1635 |
possible to run the cluster without LVM and DRBD storage, for |
1636 |
example using a shared filesystem exported from shared storage (and |
1637 |
still have live migration) |
1638 |
|
1639 |
|
1640 |
Version 1.2.7 |
1641 |
------------- |
1642 |
|
1643 |
*(Released Tue, 13 Jan 2009)* |
1644 |
|
1645 |
- Change the default reboot type in ``gnt-instance reboot`` to "hard" |
1646 |
- Reuse the old instance mac address by default on instance import, if |
1647 |
the instance name is the same. |
1648 |
- Handle situations in which the node info rpc returns incomplete |
1649 |
results (issue 46) |
1650 |
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify`` |
1651 |
- Improved version of batcher: |
1652 |
|
1653 |
- state file support |
1654 |
- instance mac address support |
1655 |
- support for HVM clusters/instances |
1656 |
|
1657 |
- Add an option to show the number of cpu sockets and nodes in |
1658 |
``gnt-node list`` |
1659 |
- Support OSes that handle more than one version of the OS api (but do |
1660 |
not change the current API in any other way) |
1661 |
- Fix ``gnt-node migrate`` |
1662 |
- ``gnt-debug`` man page |
1663 |
- Fixes various more typos and small issues |
1664 |
- Increase disk resync maximum speed to 60MB/s (from 30MB/s) |
1665 |
|
1666 |
|
1667 |
Version 1.2.6 |
1668 |
------------- |
1669 |
|
1670 |
*(Released Wed, 24 Sep 2008)* |
1671 |
|
1672 |
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
1673 |
type of disk exported to fully virtualized instances. |
1674 |
- provide access to the serial console of HVM instances |
1675 |
- instance auto_balance flag, set by default. If turned off it will |
1676 |
avoid warnings on cluster verify if there is not enough memory to fail |
1677 |
over an instance. in the future it will prevent automatically failing |
1678 |
it over when we will support that. |
1679 |
- batcher tool for instance creation, see ``tools/README.batcher`` |
1680 |
- ``gnt-instance reinstall --select-os`` to interactively select a new |
1681 |
operating system when reinstalling an instance. |
1682 |
- when changing the memory amount on instance modify a check has been |
1683 |
added that the instance will be able to start. also warnings are |
1684 |
emitted if the instance will not be able to fail over, if auto_balance |
1685 |
is true. |
1686 |
- documentation fixes |
1687 |
- sync fields between ``gnt-instance list/modify/add/import`` |
1688 |
- fix a race condition in drbd when the sync speed was set after giving |
1689 |
the device a remote peer. |
1690 |
|
1691 |
|
1692 |
Version 1.2.5 |
1693 |
------------- |
1694 |
|
1695 |
*(Released Tue, 22 Jul 2008)* |
1696 |
|
1697 |
- note: the allowed size and number of tags per object were reduced |
1698 |

1699 |
- fixed twisted 8.x compatibility |
1700 |
- fixed ``gnt-instance replace-disks`` with iallocator |
1701 |
- add TCP keepalives on twisted connections to detect restarted nodes |
1702 |
- disk increase support, see ``gnt-instance grow-disk`` |
1703 |
- implement bulk node/instance query for RAPI |
1704 |
- add tags in node/instance listing (optional) |
1705 |
- experimental migration (and live migration) support, read the man page |
1706 |
for ``gnt-instance migrate`` |
1707 |
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
1708 |
has some small improvements in handling its state file |
1709 |
|
1710 |
|
1711 |
Version 1.2.4 |
1712 |
------------- |
1713 |
|
1714 |
*(Released Fri, 13 Jun 2008)* |
1715 |
|
1716 |
- Experimental readonly, REST-based remote API implementation; |
1717 |
automatically started on master node, TCP port 5080, if enabled by |
1718 |
``--enable-rapi`` parameter to configure script. |
1719 |
- Instance allocator support. Add and import instance accept a |
1720 |
``--iallocator`` parameter, and call that instance allocator to decide |
1721 |
which node to use for the instance. The iallocator document describes |
1722 |
what's expected from an allocator script. |
1723 |
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
1724 |
``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
1725 |
node is lost there is still enough memory to fail over the instances |
1726 |
that reside on it. |
1727 |
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
1728 |
``gnt-cluster verify``, to check for site-specific compliance. All the |
1729 |
hooks will run, and their output, if any, will be displayed. Any |
1730 |
failing hook will make the verification return an error value. |
1731 |
- ``gnt-cluster verify`` now checks that its peers are reachable on the |
1732 |
primary and secondary interfaces |
1733 |
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
1734 |
that is still declared as part of the cluster and has failed. |
1735 |
- ``gnt-* list`` commands now accept a new ``-o +field`` way of |
1736 |
specifying output fields, that just adds the chosen fields to the |
1737 |
default ones. |
1738 |
- ``gnt-backup`` now has a new ``remove`` command to delete an existing |
1739 |
export from the filesystem. |
1740 |
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
1741 |
have been added. Using them you can enable/disable acpi and pae |
1742 |
support, and specify a path for a cd image to be exported to the |
1743 |
instance. These parameters as the name suggest only work on HVM |
1744 |
clusters. |
1745 |
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
1746 |
PAE support will be set to the previously hardcoded values, but the |
1747 |
(previously hardcoded) path to the CDROM ISO image will be unset and |
1748 |
if required, needs to be set manually with ``gnt-instance modify`` |
1749 |
after the upgrade. |
1750 |
- The address to which an instance's VNC console is bound is now |
1751 |
selectable per-instance, rather than being cluster wide. Of course |
1752 |
this only applies to instances controlled via VNC, so currently just |
1753 |
applies to HVM clusters. |
