Version 2.1.2 |
5 |
------------- |
6 |
|
7 |
*(Released Fri, 7 May 2010)* |
8 |
|
9 |
Another release with a long development cycle, during which many |
10 |
different features were added. |
11 |
|
12 |
Significant features |
13 |
~~~~~~~~~~~~~~~~~~~~ |
14 |
|
15 |
The KVM hypervisor now can run the individual instances as non-root, to |
16 |
reduce the impact of a VM being hijacked due to bugs in the |
17 |
hypervisor. It is possible to run all instances as a single (non-root) |
18 |
user, to manually specify a user for each instance, or to dynamically |
19 |
allocate a user out of a cluster-wide pool to each instance, with the |
20 |
guarantee that no two instances will run under the same user ID on any |
21 |
given node. |
22 |
|
23 |
An experimental RAPI client library, that can be used standalone |
24 |
(without the other Ganeti libraries), is provided in the source tree as |
25 |
``lib/rapi/client.py``. Note this client might change its interface in |
26 |
the future, as we iterate on its capabilities. |
27 |
|
28 |
A new command, ``gnt-cluster renew-crypto`` has been added to easily |
29 |
replace the cluster's certificates and crypto keys. This might help in |
30 |
case they have been compromised, or have simply expired. |
31 |
|
32 |
A new disk option for instance creation has been added that allows one |
33 |
to "adopt" currently existing logical volumes, with data |
34 |
preservation. This should allow easier migration to Ganeti from |
35 |
unmanaged (or managed via other software) instances. |
36 |
|
37 |
Another disk improvement is the possibility to convert between redundant |
38 |
(DRBD) and plain (LVM) disk configuration for an instance. This should |
39 |
allow better scalability (starting with one node and growing the |
40 |
cluster, or shrinking a two-node cluster to one node). |
41 |
|
42 |
A new feature that could help with automated node failovers has been |
43 |
implemented: if a node sees itself as offline (by querying the master |
44 |
candidates), it will try to shutdown (hard) all instances and any active |
45 |
DRBD devices. This reduces the risk of duplicate instances if an |
46 |
external script automatically failovers the instances on such nodes. To |
47 |
enable this, the cluster parameter ``maintain_node_health`` should be |
48 |
enabled; in the future this option (per the name) will enable other |
49 |
automatic maintenance features. |
50 |
|
51 |
Instance export/import now will reuse the original instance |
52 |
specifications for all parameters; that means exporting an instance, |
53 |
deleting it and the importing it back should give an almost identical |
54 |
instance. Note that the default import behaviour has changed from |
55 |
before, where it created only one NIC; now it recreates the original |
56 |
number of NICs. |
57 |
|
58 |
Cluster verify has added a few new checks: SSL certificates validity, |
59 |
/etc/hosts consistency across the cluster, etc. |
60 |
|
61 |
Other changes |
62 |
~~~~~~~~~~~~~ |
63 |
|
64 |
As usual, many internal changes were done, documentation fixes, |
65 |
etc. Among others: |
66 |
|
67 |
- Fixed cluster initialization with disabled cluster storage (regression |
68 |
introduced in 2.1.1) |
69 |
- File-based storage supports growing the disks |
70 |
- Fixed behaviour of node role changes |
71 |
- Fixed cluster verify for some corner cases, plus a general rewrite of |
72 |
cluster verify to allow future extension with more checks |
73 |
- Fixed log spamming by watcher and node daemon (regression introduced |
74 |
in 2.1.1) |
75 |
- Fixed possible validation issues when changing the list of enabled |
76 |
hypervisors |
77 |
- Fixed cleanup of /etc/hosts during node removal |
78 |
- Fixed RAPI response for invalid methods |
79 |
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon |
80 |
- Multiple small improvements to the KVM hypervisor (VNC usage, booting |
81 |
from ide disks, etc.) |
82 |
- Allow OS changes without re-installation (to record a changed OS |
83 |
outside of Ganeti, or to allow OS renames) |
84 |
- Allow instance creation without OS installation (useful for example if |
85 |
the OS will be installed manually, or restored from a backup not in |
86 |
Ganeti format) |
87 |
- Implemented option to make cluster ``copyfile`` use the replication |
88 |
network |
89 |
- Added list of enabled hypervisors to ssconf (possibly useful for |
90 |
external scripts) |
91 |
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from |
92 |
1.2 clusters |
93 |
- A partial form of node re-IP is possible via node readd, which now |
94 |
allows changed node primary IP |
95 |
- Command line utilities now show an informational message if the job is |
96 |
waiting for a lock |
97 |
- The logs of the master daemon now show the PID/UID/GID of the |
98 |
connected client |
99 |

Version 2.1.1 |
103 |
------------- |
104 |
|
105 |
*(Released Fri, 12 Mar 2010)* |
106 |
|
107 |
During the 2.1.0 long release candidate cycle, a lot of improvements and |
108 |
changes have accumulated with were released later as 2.1.1. |
109 |
|
110 |
Major changes |
111 |
~~~~~~~~~~~~~ |
112 |
|
113 |
The node evacuate command (``gnt-node evacuate``) was significantly |
114 |
rewritten, and as such the IAllocator protocol was changed - a new |
115 |
request type has been added. This unfortunate change during a stable |
116 |
series is designed to improve performance of node evacuations; on |
117 |
clusters with more than about five nodes and which are well-balanced, |
118 |
evacuation should proceed in parallel for all instances of the node |
119 |
being evacuated. As such, any existing IAllocator scripts need to be |
120 |
updated, otherwise the above command will fail due to the unknown |
121 |
request. The provided "dumb" allocator has not been updated; but the |
122 |
ganeti-htools package supports the new protocol since version 0.2.4. |
123 |
|
124 |
Another important change is increased validation of node and instance |
125 |
names. This might create problems in special cases, if invalid host |
126 |
names are being used. |
127 |
|
128 |
Also, a new layer of hypervisor parameters has been added, that sits at |
129 |
OS level between the cluster defaults and the instance ones. This allows |
130 |
customisation of virtualization parameters depending on the installed |
131 |
OS. For example instances with OS 'X' may have a different KVM kernel |
132 |
(or any other parameter) than the cluster defaults. This is intended to |
133 |
help managing a multiple OSes on the same cluster, without manual |
134 |
modification of each instance's parameters. |
135 |
|
136 |
A tool for merging clusters, ``cluster-merge``, has been added in the |
137 |
tools sub-directory. |
138 |
|
139 |
Bug fixes |
140 |
~~~~~~~~~ |
141 |
|
142 |
- Improved the int/float conversions that should make the code more |
143 |
robust in face of errors from the node daemons |
144 |
- Fixed the remove node code in case of internal configuration errors |
145 |
- Fixed the node daemon behaviour in face of inconsistent queue |
146 |
directory (e.g. read-only file-system where we can't open the files |
147 |
read-write, etc.) |
148 |
- Fixed the behaviour of gnt-node modify for master candidate demotion; |
149 |
now it either aborts cleanly or, if given the new “auto_promote” |
150 |
parameter, will automatically promote other nodes as needed |
151 |
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would |
152 |
completely prevent Ganeti from working |
153 |
- Fixed bug for instance export when not all disks were successfully |
154 |
exported |
155 |
- Fixed behaviour of node add when the new node is slow in starting up |
156 |
the node daemon |
157 |
- Fixed handling of signals in the LUXI client, which should improve |
158 |
behaviour of command-line scripts |
159 |
- Added checks for invalid node/instance names in the configuration (now |
160 |
flagged during cluster verify) |
161 |
- Fixed watcher behaviour for disk activation errors |
162 |
- Fixed two potentially endless loops in http library, which led to the |
163 |
RAPI daemon hanging and consuming 100% CPU in some cases |
164 |
- Fixed bug in RAPI daemon related to hashed passwords |
165 |
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM |
166 |
instances |
167 |
- Enhanced compatibility with non-Debian OSes, but not using absolute |
168 |
path in some commands and allowing customisation of the ssh |
169 |
configuration directory |
170 |
- Fixed possible future issue with new Python versions by abiding to the |
171 |
proper use of ``__slots__`` attribute on classes |
172 |
- Added checks that should prevent directory traversal attacks |
173 |
- Many documentation fixes based on feedback from users |
174 |
|
175 |
New features |
176 |
~~~~~~~~~~~~ |
177 |
|
178 |
- Added an “early_release” more for instance replace disks and node |
179 |
evacuate, where we release locks earlier and thus allow higher |
180 |
parallelism within the cluster |
181 |
- Added watcher hooks, intended to allow the watcher to restart other |
182 |
daemons (e.g. from the ganeti-nbma project), but they can be used of |
183 |
course for any other purpose |
184 |
- Added a compile-time disable for DRBD barriers, to increase |
185 |
performance if the administrator trusts the power supply or the |
186 |
storage system to not lose writes |
187 |
- Added the option of using syslog for logging instead of, or in |
188 |
addition to, Ganeti's own log files |
189 |
- Removed boot restriction for paravirtual NICs for KVM, recent versions |
190 |
can indeed boot from a paravirtual NIC |
191 |
- Added a generic debug level for many operations; while this is not |
192 |
used widely yet, it allows one to pass the debug value all the way to |
193 |
the OS scripts |
194 |
- Enhanced the hooks environment for instance moves (failovers, |
195 |
migrations) where the primary/secondary nodes changed during the |
196 |
operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars |
197 |
- Enhanced data validations for many user-supplied values; one important |
198 |
item is the restrictions imposed on instance and node names, which |
199 |
might reject some (invalid) host names |
200 |
- Add a configure-time option to disable file-based storage, if it's not |
201 |
needed; this allows greater security separation between the master |
202 |
node and the other nodes from the point of view of the inter-node RPC |
203 |
protocol |
204 |
- Added user notification in interactive tools if job is waiting in the |
205 |
job queue or trying to acquire locks |
206 |
- Added log messages when a job is waiting for locks |
207 |
- Added filtering by node tags in instance operations which admit |
208 |
multiple instances (start, stop, reboot, reinstall) |
209 |
- Added a new tool for cluster mergers, ``cluster-merge`` |
210 |
- Parameters from command line which are of the form ``a=b,c=d`` can now |
211 |
use backslash escapes to pass in values which contain commas, |
212 |
e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value |
213 |
``b,c`` |
214 |
- For KVM, the instance name is the first parameter passed to KVM, so |
215 |
that it's more visible in the process list |
216 |
|
217 |
|
218 |
Version 2.1.0 |
219 |
------------- |
220 |
|
221 |
*(Released Tue, 2 Mar 2010)* |
222 |
|
223 |
Ganeti 2.1 brings many improvements with it. Major changes: |
224 |
|
225 |
- Added infrastructure to ease automated disk repairs |
226 |
- Added new daemon to export configuration data in a cheaper way than |
227 |
using the remote API |
228 |
- Instance NICs can now be routed instead of being associated with a |
229 |
networking bridge |
230 |
- Improved job locking logic to reduce impact of jobs acquiring multiple |
231 |
locks waiting for other long-running jobs |
232 |
|
233 |
In-depth implementation details can be found in the Ganeti 2.1 design |
234 |
document. |

297 |
- Added more unittests |
298 |

|
389 |
*(Released Fri, 7 Aug 2009)* |
390 |
|
391 |
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
392 |
to allow using the pre-2.0.2 behaviour in activation, if any existing |
393 |

403 |
|
404 |
Version 2.0.2 |
405 |
------------- |
406 |
|
407 |
*(Released Fri, 17 Jul 2009)* |
408 |
|
409 |
- Added experimental support for stripped logical volumes; this should |
410 |
enhance performance but comes with a higher complexity in the block |
411 |
device handling; stripping is only enabled when passing |
412 |
``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
413 |
affected even in the non-stripped mode |
414 |
- Improved resiliency against transient failures at the end of DRBD |
415 |
resyncs, and in general of DRBD resync checks |
416 |
- Fixed a couple of issues with exports and snapshot errors |
417 |
- Fixed a couple of issues in instance listing |
418 |
- Added display of the disk size in ``gnt-instance info`` |
419 |
- Fixed checking for valid OSes in instance creation |
420 |
- Fixed handling of the "vcpus" parameter in instance listing and in |
421 |
general of invalid parameters |
422 |
- Fixed http server library, and thus RAPI, to handle invalid |
423 |
username/password combinations correctly; this means that now they |
424 |
report unauthorized for queries too, not only for modifications, |
425 |
allowing earlier detect of configuration problems |
426 |
- Added a new "role" node list field, equivalent to the master/master |
427 |
candidate/drained/offline flags combinations |
428 |
- Fixed cluster modify and changes of candidate pool size |
429 |
- Fixed cluster verify error messages for wrong files on regular nodes |
430 |
- Fixed a couple of issues with node demotion from master candidate role |
431 |
- Fixed node readd issues |
432 |
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
433 |
- Added a new ``--no-voting`` option for masterfailover to fix failover |
434 |
on two-nodes clusters when the former master node is unreachable |
435 |
- Added instance reinstall over RAPI |
436 |
|
437 |
|
438 |
Version 2.0.1 |
439 |
------------- |
440 |
|
441 |
*(Released Tue, 16 Jun 2009)* |
442 |
|
443 |
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
444 |
allow re-adding the start in single-user option (regression from 1.2) |
445 |
- the watcher writes the instance status to a file, to allow monitoring |
446 |
to report the instance status (from the master) based on cached |
447 |
results of the watcher's queries; while this can get stale if the |
448 |
watcher is being locked due to other work on the cluster, this is |
449 |
still an improvement |
450 |
- the watcher now also restarts the node daemon and the rapi daemon if |
451 |
they died |
452 |
- fixed the watcher to handle full and drained queue cases |
453 |
- hooks export more instance data in the environment, which helps if |
454 |
hook scripts need to take action based on the instance's properties |
455 |
(no longer need to query back into ganeti) |
456 |
- instance failovers when the instance is stopped do not check for free |
457 |
RAM, so that failing over a stopped instance is possible in low memory |
458 |
situations |
459 |
- rapi uses queries for tags instead of jobs (for less job traffic), and |
460 |
for cluster tags it won't talk to masterd at all but read them from |
461 |
ssconf |
462 |
- a couple of error handling fixes in RAPI |
463 |
- drbd handling: improved the error handling of inconsistent disks after |
464 |
resync to reduce the frequency of "there are some degraded disks for |
465 |
this instance" messages |
466 |
- fixed a bug in live migration when DRBD doesn't want to reconnect (the |
467 |
error handling path called a wrong function name) |
468 |
|
469 |
|
470 |
Version 2.0.0 final |
471 |
------------------- |
472 |
|
473 |
*(Released Wed, 27 May 2009)* |
474 |
|
475 |
- no changes from rc5 |

480 |
|
481 |
*(Released Wed, 20 May 2009)* |
482 |
|
483 |
- fix a couple of bugs (validation, argument checks) |
484 |
- fix ``gnt-cluster getmaster`` on non-master nodes (regression) |
485 |
- some small improvements to RAPI and IAllocator |
486 |

|
489 |
Version 2.0 release candidate 4 |
490 |
------------------------------- |
491 |
|
492 |
*(Released Mon, 27 Apr 2009)* |
493 |
|
494 |
- change the OS list to not require locks; this helps with big clusters |
495 |
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the |
496 |
volume group is broken |
497 |
- ``gnt-instance info``, without any arguments, doesn't run for all |
498 |
instances anymore; either pass ``--all`` or pass the desired |
499 |
instances; this helps against mistakes on big clusters where listing |
500 |
the information for all instances takes a long time |
501 |
- miscellaneous doc and man pages fixes |
502 |
|
503 |
|
504 |
Version 2.0 release candidate 3 |
505 |
------------------------------- |
506 |
|
507 |
*(Released Wed, 8 Apr 2009)* |
508 |
|
509 |
- Change the internal locking model of some ``gnt-node`` commands, in |
510 |
order to reduce contention (and blocking of master daemon) when |
511 |
batching many creation/reinstall jobs |
512 |
- Fixes to Xen soft reboot |
513 |
- No longer build documentation at build time, instead distribute it in |
514 |
the archive, in order to reduce the need for the whole docbook/rst |
515 |
toolchains |
516 |
|
517 |
|
518 |
Version 2.0 release candidate 2 |
519 |
------------------------------- |
520 |
|
521 |
*(Released Fri, 27 Mar 2009)* |
522 |
|
523 |

524 |
- Fix watcher startup sequence, improves the behaviour of busy clusters |
525 |
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance |
526 |
replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC |
527 |
bind address and other places |
528 |
- Some documentation fixes and updates |
529 |
|
530 |
|
531 |
Version 2.0 release candidate 1 |
532 |
------------------------------- |
533 |
|
534 |
*(Released Mon, 2 Mar 2009)* |
535 |
|
536 |
- More documentation updates, now all docs should be more-or-less |
537 |
up-to-date |
538 |
- A couple of small fixes (mixed hypervisor clusters, offline nodes, |
539 |
etc.) |
540 |
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM |
541 |
and KVM) |
542 |
- Fix an issue related to $libdir/run/ganeti and cluster creation |
543 |
|
544 |
|
545 |
Version 2.0 beta 2 |
546 |
------------------ |
547 |
|
548 |
*(Released Thu, 19 Feb 2009)* |
549 |
|
550 |
- Xen PVM and KVM have switched the default value for the instance root |
551 |
disk to the first partition on the first drive, instead of the whole |
552 |
drive; this means that the OS installation scripts must be changed |
553 |
accordingly |
554 |
- Man pages have been updated |
555 |
- RAPI has been switched by default to HTTPS, and the exported functions |
556 |
should all work correctly |
557 |
- RAPI v1 has been removed |
558 |
- Many improvements to the KVM hypervisor |
559 |
- Block device errors are now better reported |
560 |
- Many other bugfixes and small improvements |
561 |
|
562 |
|
563 |
Version 2.0 beta 1 |
564 |
------------------ |
565 |
|
566 |
*(Released Mon, 26 Jan 2009)* |
567 |
|
568 |
- Version 2 is a general rewrite of the code and therefore the |
569 |
differences are too many to list, see the design document for 2.0 in |
570 |
the ``doc/`` subdirectory for more details |
571 |
- In this beta version there is not yet a migration path from 1.2 (there |
572 |
will be one in the final 2.0 release) |
573 |
- A few significant changes are: |
574 |
|
575 |
- all commands are executed by a daemon (``ganeti-masterd``) and the |
576 |
various ``gnt-*`` commands are just front-ends to it |
577 |
- all the commands are entered into, and executed from a job queue, |
578 |
see the ``gnt-job(8)`` manpage |
579 |
- the RAPI daemon supports read-write operations, secured by basic |
580 |
HTTP authentication on top of HTTPS |
581 |
- DRBD version 0.7 support has been removed, DRBD 8 is the only |
582 |
supported version (when migrating from Ganeti 1.2 to 2.0, you need |
583 |
to migrate to DRBD 8 first while still running Ganeti 1.2) |
584 |
- DRBD devices are using statically allocated minor numbers, which |
585 |
will be assigned to existing instances during the migration process |
586 |
- there is support for both Xen PVM and Xen HVM instances running on |
587 |
the same cluster |
588 |
- KVM virtualization is supported too |
589 |
- file-based storage has been implemented, which means that it is |
590 |
possible to run the cluster without LVM and DRBD storage, for |
591 |
example using a shared filesystem exported from shared storage (and |
592 |
still have live migration) |
593 |
|
594 |
|
595 |
Version 1.2.7 |
596 |
------------- |
597 |
|
598 |
*(Released Tue, 13 Jan 2009)* |
599 |
|
600 |
- Change the default reboot type in ``gnt-instance reboot`` to "hard" |
601 |
- Reuse the old instance mac address by default on instance import, if |
602 |
the instance name is the same. |
603 |
- Handle situations in which the node info rpc returns incomplete |
604 |
results (issue 46) |
605 |
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify`` |
606 |
- Improved version of batcher: |
607 |
|
608 |
- state file support |
609 |
- instance mac address support |
610 |
- support for HVM clusters/instances |
611 |
|
612 |
- Add an option to show the number of cpu sockets and nodes in |
613 |
``gnt-node list`` |
614 |
- Support OSes that handle more than one version of the OS api (but do |
615 |
not change the current API in any other way) |
616 |
- Fix ``gnt-node migrate`` |
617 |
- ``gnt-debug`` man page |
618 |
- Fixes various more typos and small issues |
619 |
- Increase disk resync maximum speed to 60MB/s (from 30MB/s) |
620 |
|
621 |
|
622 |
Version 1.2.6 |
623 |
------------- |
624 |
|
625 |
*(Released Wed, 24 Sep 2008)* |
626 |
|
627 |
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
628 |
type of disk exported to fully virtualized instances. |
629 |
- provide access to the serial console of HVM instances |
630 |
- instance auto_balance flag, set by default. If turned off it will |
631 |
avoid warnings on cluster verify if there is not enough memory to fail |
632 |
over an instance. in the future it will prevent automatically failing |
633 |
it over when we will support that. |
634 |
- batcher tool for instance creation, see ``tools/README.batcher`` |
635 |
- ``gnt-instance reinstall --select-os`` to interactively select a new |
636 |
operating system when reinstalling an instance. |
637 |
- when changing the memory amount on instance modify a check has been |
638 |
added that the instance will be able to start. also warnings are |
639 |
emitted if the instance will not be able to fail over, if auto_balance |
640 |
is true. |
641 |
- documentation fixes |
642 |
- sync fields between ``gnt-instance list/modify/add/import`` |
643 |
- fix a race condition in drbd when the sync speed was set after giving |
644 |
the device a remote peer. |
645 |
|
646 |
|
647 |
Version 1.2.5 |
648 |
------------- |
649 |
|
650 |
*(Released Tue, 22 Jul 2008)* |
651 |
|
652 |
- note: the allowed size and number of tags per object were reduced |
653 |
- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups |
654 |
- fixed twisted 8.x compatibility |
655 |
- fixed ``gnt-instance replace-disks`` with iallocator |
656 |
- add TCP keepalives on twisted connections to detect restarted nodes |
657 |
- disk increase support, see ``gnt-instance grow-disk`` |
658 |
- implement bulk node/instance query for RAPI |
659 |
- add tags in node/instance listing (optional) |
660 |
- experimental migration (and live migration) support, read the man page |
661 |
for ``gnt-instance migrate`` |
662 |
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
663 |
has some small improvements in handling its state file |
664 |
|
665 |
|
666 |
Version 1.2.4 |
667 |
------------- |
668 |
|
669 |
*(Released Fri, 13 Jun 2008)* |
670 |
|
671 |
- Experimental readonly, REST-based remote API implementation; |
672 |
automatically started on master node, TCP port 5080, if enabled by |
673 |
``--enable-rapi`` parameter to configure script. |
674 |
- Instance allocator support. Add and import instance accept a |
675 |
``--iallocator`` parameter, and call that instance allocator to decide |
676 |
which node to use for the instance. The iallocator document describes |
677 |
what's expected from an allocator script. |
678 |
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
679 |
``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
680 |
node is lost there is still enough memory to fail over the instances |
681 |
that reside on it. |
682 |
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
683 |
``gnt-cluster verify``, to check for site-specific compliance. All the |
684 |
hooks will run, and their output, if any, will be displayed. Any |
685 |
failing hook will make the verification return an error value. |
686 |
- ``gnt-cluster verify`` now checks that its peers are reachable on the |
687 |
primary and secondary interfaces |
688 |
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
689 |
that is still declared as part of the cluster and has failed. |
690 |
- ``gnt-* list`` commands now accept a new ``-o +field`` way of |
691 |
specifying output fields, that just adds the chosen fields to the |
692 |
default ones. |
693 |
- ``gnt-backup`` now has a new ``remove`` command to delete an existing |
694 |
export from the filesystem. |
695 |
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
696 |
have been added. Using them you can enable/disable acpi and pae |
697 |
support, and specify a path for a cd image to be exported to the |
698 |
instance. These parameters as the name suggest only work on HVM |
699 |
clusters. |
700 |
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
701 |
PAE support will be set to the previously hardcoded values, but the |
702 |
(previously hardcoded) path to the CDROM ISO image will be unset and |
703 |
if required, needs to be set manually with ``gnt-instance modify`` |
704 |
after the upgrade. |
705 |
- The address to which an instance's VNC console is bound is now |
706 |
selectable per-instance, rather than being cluster wide. Of course |
707 |
this only applies to instances controlled via VNC, so currently just |
708 |
applies to HVM clusters. |
709 |
|
710 |
|
711 |
Version 1.2.3 |
712 |
------------- |
713 |
|
714 |
*(Released Mon, 18 Feb 2008)* |
715 |
|
716 |
- more tweaks to the disk activation code (especially helpful for DRBD) |
717 |
- change the default ``gnt-instance list`` output format, now there is |
718 |
one combined status field (see the manpage for the exact values this |
719 |
field will have) |
720 |
- some more fixes for the mac export to hooks change |
721 |
- make Ganeti not break with DRBD 8.2.x (which changed the version |
722 |
format in ``/proc/drbd``) (issue 24) |
723 |
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk |
724 |
template, allowing migration from DRBD0.7+MD to DRBD8 |
725 |
|
726 |
|
727 |
Version 1.2.2 |
728 |
------------- |

731 |
|
732 |
- fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM |
733 |
support (issue 23) |
734 |
- add command aliases infrastructure and a few aliases |
735 |
- allow listing of VCPUs in the ``gnt-instance list`` and improve the |
736 |
man pages and the ``--help`` option of ``gnt-node |
737 |
list``/``gnt-instance list`` |
738 |
- fix ``gnt-backup list`` with down nodes (issue 21) |
739 |
- change the tools location (move from $pkgdatadir to $pkglibdir/tools) |
740 |
- fix the dist archive and add a check for including svn/git files in |
741 |
the future |
742 |
- some developer-related changes: improve the burnin and the QA suite, |
743 |
add an upload script for testing during development |
744 |

752 |
"Initializing the cluster" |
753 |
- allow for the PVM hypervisor per-instance kernel and initrd paths |
754 |
- add a new command ``gnt-cluster verify-disks`` which uses a new |
755 |
algorithm to improve the reconnection of the DRBD pairs if the device |
756 |
on the secondary node has gone away |
757 |
- make logical volume code auto-activate LVs at disk activation time |
758 |

|
769 |
*(Released Tue, 4 Dec 2007)* |
770 |
|
771 |
- Log the ``xm create`` output to the node daemon log on failure (to |
772 |
help diagnosing the error) |
773 |
- In debug mode, log all external commands output if failed to the logs |
774 |
- Change parsing of lvm commands to ignore stderr |
775 |
|
776 |
|
777 |
Version 1.2b3 |
778 |
------------- |
779 |
|
780 |
*(Released Wed, 28 Nov 2007)* |
781 |
|
782 |

Version 1.2b2 |
790 |
------------- |
791 |
|
792 |
*(Released Tue, 13 Nov 2007)* |
793 |
|
794 |
- Change configuration file format from Python's Pickle to JSON. |
795 |
Upgrading is possible using the cfgupgrade utility. |
796 |
- Add support for DRBD 8.0 (new disk template ``drbd``) which allows for |
797 |
faster replace disks and is more stable (DRBD 8 has many improvements |
798 |
compared to DRBD 0.7) |
799 |
- Added command line tags support (see man pages for ``gnt-instance``, |
800 |
``gnt-node``, ``gnt-cluster``) |
801 |
- Added instance rename support |
802 |

811 |
non-standard ``-S`` option |
812 |
- Now the OS definitions are searched for in multiple, configurable |
813 |
paths (easier for distros to package) |
814 |
- Some changes to the hooks infrastructure (especially the new |
815 |
post-configuration update hook) |
816 |
- Other small bugfixes |
