Incompatible/important changes and bugfixes
10
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
11

    
12
- The default of the ``/2/instances/[instance_name]/rename`` RAPI
13
  resource's ``ip_check`` parameter changed from ``True`` to ``False``
14
  to match the underlying LUXI interface.
15
- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use
16
  body parameters, see :doc:`RAPI documentation <rapi>`. The server does
17
  not maintain backwards-compatibility as the underlying operation
18
  changed in an incompatible way. The RAPI client can talk to old
19
  servers, but it needs to be told so as the return value changed.
20
- When creating file-based instances via RAPI, the ``file_driver``
21
  parameter no longer defaults to ``loop`` and must be specified.
22
- The deprecated ``bridge`` NIC parameter is no longer supported. Use
23
  ``link`` instead.
24
- Support for the undocumented and deprecated RAPI instance creation
25
  request format version 0 has been dropped. Use version 1, supported
26
  since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
27
- Pyparsing 1.4.6 or above is required, see :doc:`installation
28
  documentation <install>`.
29
- The "cluster-verify" hooks are now executed per group by the
30
  ``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior
31
  if you just run ``gnt-cluster verify``, which generates one opcode per
32
  group.
33
- The environment as passed to the OS scripts is cleared, and thus no
34
  environment variables defined in the node daemon's environment will be
35
  inherited by the scripts.
36
- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been
37
  deprecated.
38
- :doc:`New iallocator modes <design-multi-reloc>` have been added to
39
  support operations involving multiple node groups.
40
- Offline nodes are ignored when failing over an instance.
41

    
42
New features
43
~~~~~~~~~~~~
44

    
45
- The ganeti-htools project has been merged into the ganeti-core source
46
  tree and will be built as part of Ganeti (see :doc:`install-quick`).
47
- Implemented support for :doc:`shared storage <design-shared-storage>`.
48
- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting
49
  GPT-style partition tables (requires `parted
50
  <http://www.gnu.org/s/parted/>`_).
51
- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor.
52
- Allowed adding tags on instance creation.
53
- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`)
54
- Allow instances to be started in a paused state, enabling the user to
55
  see the complete console output on boot using the console.
56
- Added new hypervisor flag to control default reboot behaviour
57
  (``reboot_behavior``).
58
- Added support for KVM keymaps (hypervisor parameter ``keymap``).
59
- Improved out-of-band management support:
60

    
61
  - Added ``gnt-node health`` command reporting the health status of
62
    nodes.
63
  - Added ``gnt-node power`` command to manage power status of nodes.
64
  - Added command for emergency power-off (EPO), ``gnt-cluster epo``.
65

    
66
- Instance migration can fall back to failover if instance is not
67
  running.
68
- Filters can be used when listing nodes, instances, groups and locks;
69
  see *ganeti(7)* manpage.
70
- Added post-execution status as variables to :doc:`hooks <hooks>`
71
  environment.
72
- Instance tags are exported/imported together with the instance.
73
- When given an explicit job ID, ``gnt-job info`` will work for archived
74
  jobs.
75
- Jobs can define dependencies on other jobs (not yet supported via
76
  RAPI or command line, but used by internal commands and usable via
77
  LUXI).
78

    
79
  - Lock monitor (``gnt-debug locks``) shows jobs waiting for
80
    dependencies.
81

    
82
- Instance failover is now available as a RAPI resource
83
  (``/2/instances/[instance_name]/failover``).
84
- ``gnt-instance info`` defaults to static information if primary node
85
  is offline.
86
- Opcodes have a new ``comment`` attribute.
87
- Added basic SPICE support to KVM hypervisor.
88
- ``tools/ganeti-listrunner`` allows passing of arguments to executable.
89

    
90
Node group improvements
91
~~~~~~~~~~~~~~~~~~~~~~~
92

    
93
- ``gnt-cluster verify`` has been modified to check groups separately,
94
  thereby improving performance.
95
- Node group support has been added to ``gnt-cluster verify-disks``,
96
  which now operates per node group.
97
- Watcher has been changed to work better with node groups.
98

    
99
  - One process and state file per node group.
100
  - Slow watcher in one group doesn't block other group's watcher.
101

    
102
- Added new command, ``gnt-group evacuate``, to move all instances in a
103
  node group to other groups.
104
- Added ``gnt-instance change-group`` to move an instance to another
105
  node group.
106
- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support
107
  per-group operations.
108
- Node groups can be tagged.
109
- Some operations switch from an exclusive to a shared lock as soon as
110
  possible.
111
- Instance's primary and secondary nodes' groups are now available as
112
  query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group``
113
  and ``snodes.group.uuid``).
114

    
115
Misc
116
~~~~
117

    
118
- Numerous updates to documentation and manpages.
119

    
120
  - :doc:`RAPI <rapi>` documentation now has detailed parameter
121
    descriptions.
122

    
123
- A lockset's internal lock is now also visible in lock monitor.
124
- Log messages from job queue workers now contain information about the
125
  opcode they're processing.
126
- ``gnt-instance console`` no longer requires the instance lock.
127
- A short delay when waiting for job changes reduces the number of LUXI
128
  requests significantly.
129
- DRBD metadata volumes are overwritten with zeros during disk creation.
130

192

    
193
Many bug-fixes and a few small features:
194

    
195

196
  issues when you tried to add an instance with two MAC addresses in one
197
  request
198
- KVM: fixed per-instance stored UID value
199
- KVM: configure bridged NICs at migration start

201
  (>= 0.14)
202
- Added OS search path to ``gnt-cluster info``
203
- Fixed an issue with ``file_storage_dir`` where you were forced to
204
  provide an absolute path, but the documentation states it is a
205
  relative path, the documentation was right
206
- Added a new parameter to instance stop/start called ``--no-remember``
207
  that will make the state change to not be remembered
208

223

    
224
Version 2.4.2
225
-------------
226

    
227
*(Released Thu, 12 May 2011)*
228

    
229
Many bug-fixes and a few new small features:
230

    
231
- Fixed a bug related to log opening failures
232
- Fixed a bug in instance listing with orphan instances
233
- Fixed a bug which prevented resetting the cluster-level node parameter
234
  ``oob_program`` to the default
235
- Many fixes related to the ``cluster-merge`` tool
236
- Fixed a race condition in the lock monitor, which caused failures
237
  during (at least) creation of many instances in parallel
238
- Improved output for gnt-job info
239
- Removed the quiet flag on some ssh calls which prevented debugging
240
  failures
241
- Improved the N+1 failure messages in cluster verify by actually
242
  showing the memory values (needed and available)
243
- Increased lock attempt timeouts so that when executing long operations
244
  (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire'
245
  too early and thus prevent the use of the 'fair' mechanism
246
- Changed instance query data (``gnt-instance info``) to not acquire
247
  locks unless needed, thus allowing its use on locked instance if only
248
  static information is asked for
249
- Improved behaviour with filesystems that do not support rename on an
250
  opened file
251
- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which
252
  kept locks on all nodes during the wipe, which is unneeded
253
- Fixed ``gnt-watcher`` handling of errors during hooks execution
254
- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than
255
  10GiB) which caused the wipe to fail right at the end in some cases
256
- Fixed master IP activation when doing master failover with no-voting
257
- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of
258
  the master node itself
259
- Fixed potential data-loss in under disk full conditions, where Ganeti
260
  wouldn't check correctly the return code and would consider
261
  partially-written files 'correct'
262
- Fixed bug related to multiple VGs and DRBD disk replacing
263
- Added new disk parameter ``metavg`` that allows placement of the meta
264
  device for DRBD in a different volume group
265
- Fixed error handling in the node daemon when the system libc doesn't
266
  have major number 6 (i.e. if ``libc.so.6`` is not the actual libc)
267
- Fixed lock release during replace-disks, which kept cluster-wide locks
268
  when doing disk replaces with an iallocator script
269
- Added check for missing bridges in cluster verify
270
- Handle EPIPE errors while writing to the terminal better, so that
271
  piping the output to e.g. ``less`` doesn't cause a backtrace
272
- Fixed rare case where a ^C during Luxi calls could have been
273
  interpreted as server errors, instead of simply terminating
274
- Fixed a race condition in LUGroupAssignNodes (``gnt-group
275
  assign-nodes``)
276
- Added a few more parameters to the KVM hypervisor, allowing a second
277
  CDROM, custom disk type for CDROMs and a floppy image
278
- Removed redundant message in instance rename when the name is given
279
  already as a FQDN
280
- Added option to ``gnt-instance recreate-disks`` to allow creating the
281
  disks on new nodes, allowing recreation when the original instance
282
  nodes are completely gone
283
- Added option when converting disk templates to DRBD to skip waiting
284
  for the resync, in order to make the instance available sooner
285
- Added two new variables to the OS scripts environment (containing the
286
  instance's nodes)
287
- Made the root_path and optional parameter for the xen-pvm hypervisor,
288
  to allow use of ``pvgrub`` as bootloader
289
- Changed the instance memory modifications to only check out-of-memory
290
  conditions on memory increases, and turned the secondary node warnings
291
  into errors (they can still be overridden via ``--force``)
292
- Fixed the handling of a corner case when the Python installation gets
293
  corrupted (e.g. a bad disk) while ganeti-noded is running and we try
294
  to execute a command that doesn't exist
295
- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary
296
  node of the instance returned failures during instance shutdown; this
297
  adds the option ``--ignore-consistency`` to gnt-instance move
298

    
299
And as usual, various improvements to the error messages, documentation
300
and man pages.
301

    
302
Version 2.4.1
303
-------------
304

    
305
*(Released Wed, 09 Mar 2011)*
306

    
307
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
308
the RAPI users file if run twice (even with ``--dry-run``).
309

    
310
The release fixes that bug (nothing else changed).
311

    
312

    
313
Version 2.4.0
314
-------------
315

    
316
*(Released Mon, 07 Mar 2011)*
317

    
318
Final 2.4.0 release. Just a few small fixes:
319

    
320
- Fixed RAPI node evacuate
321
- Fixed the kvm-ifup script
322
- Fixed internal error handling for special job cases
323
- Updated man page to specify the escaping feature for options
324

    
325

    
326
Version 2.4.0 rc3
327
-----------------
328

    
329
*(Released Mon, 28 Feb 2011)*
330

    
331
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
332
that this feature wiped the disks of the wrong instance, leading to loss
333
of data.
334

    
335
Other changes:
336

    
337
- Fixed title of query field containing instance name
338
- Expanded the glossary in the documentation
339
- Fixed one unittest (internal issue)
340

    
341

    
342
Version 2.4.0 rc2
343
-----------------
344

    
345
*(Released Mon, 21 Feb 2011)*
346

    
347
A number of bug fixes plus just a couple functionality changes.
348

    
349
On the user-visible side, the ``gnt-* list`` command output has changed
350
with respect to "special" field states. The current rc1 style of display
351
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
352
the default output mode special fields states are displayed as follows:
353

    
354
- Offline resource: ``*``
355
- Unavailable/not applicable: ``-``
356
- Data missing (RPC failure): ``?``
357
- Unknown field: ``??``
358

    
359
Another user-visible change is the addition of ``--force-join`` to
360
``gnt-node add``.
361

    
362
As for bug fixes:
363

    
364
- ``tools/cluster-merge`` has seen many fixes and is now enabled again
365
- Fixed regression in RAPI/instance reinstall where all parameters were
366
  required (instead of optional)
367
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
368
- Fixed iallocator usage (offline nodes were not considered offline)
369
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes
370
- Fixed hypervisor and OS parameter validation with respect to
371
  non-vm_capable nodes
372
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
373
  cosmetic)
374
- Fixed ``tools/listrunner`` with respect to agent-based usage
375

    
376

    
377
Version 2.4.0 rc1
378
-----------------
379

    
380
*(Released Fri,  4 Feb 2011)*
381

    
382
Many changes and fixes since the beta1 release. While there were some
383
internal changes, the code has been mostly stabilised for the RC
384
release.
385

    
386
Note: the dumb allocator was removed in this release, as it was not kept
387
up-to-date with the IAllocator protocol changes. It is recommended to
388
use the ``hail`` command from the ganeti-htools package.
389

    
390
Note: the 2.4 and up versions of Ganeti are not compatible with the
391
0.2.x branch of ganeti-htools. You need to upgrade to
392
ganeti-htools-0.3.0 (or later).
393

    
394
Regressions fixed from 2.3
395
~~~~~~~~~~~~~~~~~~~~~~~~~~
396

    
397
- Fixed the ``gnt-cluster verify-disks`` command
398
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to
399
  serially on nodes)
400
- Fixed disk adoption breakage
401
- Fixed wrong headers in instance listing for field aliases
402

    
403
Other bugs fixed
404
~~~~~~~~~~~~~~~~
405

    
406
- Fixed corner case in KVM handling of NICs
407
- Fixed many cases of wrong handling of non-vm_capable nodes
408
- Fixed a bug where a missing instance symlink was not possible to
409
  recreate with any ``gnt-*`` command (now ``gnt-instance
410
  activate-disks`` does it)
411
- Fixed the volume group name as reported by ``gnt-cluster
412
  verify-disks``
413
- Increased timeouts for the import-export code, hopefully leading to
414
  fewer aborts due network or instance timeouts
415
- Fixed bug in ``gnt-node list-storage``
416
- Fixed bug where not all daemons were started on cluster
417
  initialisation, but only at the first watcher run
418
- Fixed many bugs in the OOB implementation
419
- Fixed watcher behaviour in presence of instances with offline
420
  secondaries
421
- Fixed instance list output for instances running on the wrong node
422
- a few fixes to the cluster-merge tool, but it still cannot merge
423
  multi-node groups (currently it is not recommended to use this tool)
424

    
425

    
426
Improvements
427
~~~~~~~~~~~~
428

    
429
- Improved network configuration for the KVM hypervisor
430
- Added e1000 as a supported NIC for Xen-HVM
431
- Improved the lvmstrap tool to also be able to use partitions, as
432
  opposed to full disks
433
- Improved speed of disk wiping (the cluster parameter
434
  ``prealloc_wipe_disks``, so that it has a low impact on the total time
435
  of instance creations
436
- Added documentation for the OS parameters
437
- Changed ``gnt-instance deactivate-disks`` so that it can work if the
438
  hypervisor is not responding
439
- Added display of blacklisted and hidden OS information in
440
  ``gnt-cluster info``
441
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
442
  NIC and node parameters, which might create problems with currently
443
  invalid (but undetected) configuration files, but prevents validation
444
  failures when unrelated parameters are modified
445
- Changed cluster initialisation to wait for the master daemon to become
446
  available
447
- Expanded the RAPI interface:
448

    
449
  - Added config redistribution resource
450
  - Added activation/deactivation of instance disks
451
  - Added export of console information
452

    
453
- Implemented log file reopening on SIGHUP, which allows using
454
  logrotate(8) for the Ganeti log files
455
- Added a basic OOB helper script as an example
456

    
457

    
458
Version 2.4.0 beta1
459
-------------------
460

    
461
*(Released Fri, 14 Jan 2011)*
462

    
463
User-visible
464
~~~~~~~~~~~~
465

    
466
- Fixed timezone issues when formatting timestamps
467
- Added support for node groups, available via ``gnt-group`` and other
468
  commands
469
- Added out-of-band framework and management, see :doc:`design
470
  document <design-oob>`
471
- Removed support for roman numbers from ``gnt-node list`` and
472
  ``gnt-instance list``.
473
- Allowed modification of master network interface via ``gnt-cluster
474
  modify --master-netdev``
475
- Accept offline secondaries while shutting down instance disks
476
- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors
477
- Added support for multiple LVM volume groups
478
- Avoid sorting nodes for ``gnt-node list`` if specific nodes are
479
  requested
480
- Added commands to list available fields:
481

    
482
  - ``gnt-node list-fields``
483
  - ``gnt-group list-fields``
484
  - ``gnt-instance list-fields``
485

    
486
- Updated documentation and man pages
487

Integration
489
~~~~~~~~~~~
490

    
491
- Moved ``rapi_users`` file into separate directory, now named
492
  ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
493
  symlink
494
- Added new tool for running commands on many machines,
495
  ``tools/ganeti-listrunner``
496
- Implemented more verbose result in ``OpInstanceConsole`` opcode, also
497
  improving the ``gnt-instance console`` output
498
- Allowed customisation of disk index separator at ``configure`` time
499
- Export node group allocation policy to :doc:`iallocator <iallocator>`
500
- Added support for non-partitioned md disks in ``lvmstrap``
501
- Added script to gracefully power off KVM instances
502
- Split ``utils`` module into smaller parts
503
- Changed query operations to return more detailed information, e.g.
504
  whether an information is unavailable due to an offline node. To use
505
  this new functionality, the LUXI call ``Query`` must be used. Field
506
  information is now stored by the master daemon and can be retrieved
507
  using ``QueryFields``. Instances, nodes and groups can also be queried
508
  using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
509
  exposed via RAPI). The following commands make use of this
510
  infrastructure change:
511

    
512
  - ``gnt-group list``
513
  - ``gnt-group list-fields``
514
  - ``gnt-node list``
515
  - ``gnt-node list-fields``
516
  - ``gnt-instance list``
517
  - ``gnt-instance list-fields``
518
  - ``gnt-debug locks``
519

    
520
Remote API
521
~~~~~~~~~~
522

    
523
- New RAPI resources (see :doc:`rapi`):
524

    
525
  - ``/2/modify``
526
  - ``/2/groups``
527
  - ``/2/groups/[group_name]``
528
  - ``/2/groups/[group_name]/assign-nodes``
529
  - ``/2/groups/[group_name]/modify``
530
  - ``/2/groups/[group_name]/rename``
531
  - ``/2/instances/[instance_name]/disk/[disk_index]/grow``
532

    
533
- RAPI changes:
534

    
535
  - Implemented ``no_install`` for instance creation
536
  - Implemented OS parameters for instance reinstallation, allowing
537
    use of special settings on reinstallation (e.g. for preserving data)
538

735

    
736
Version 2.2.0 rc0
737
-----------------
738

    
739
*(Released Fri, 30 Jul 2010)*
740

    
741
Important change: the internal RPC mechanism between Ganeti nodes has
742
changed from using a home-grown http library (based on the Python base
743
libraries) to use the PycURL library. This requires that PycURL is
744
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
745
against GnuTLS by default. cURL's support for GnuTLS had known issues
746
before cURL 7.21.0 and we recommend using the latest cURL release or
747
linking against OpenSSL. Most other distributions already link PycURL
748
and cURL against OpenSSL. The command::
749

    
750
  python -c 'import pycurl; print pycurl.version'
751

    
752
can be used to determine the libraries PycURL and cURL are linked
753
against.
754

    
755
Other significant changes:
756

    
757
- Rewrote much of the internals of the job queue, in order to achieve
758
  better parallelism; this decouples job query operations from the job
759
  processing, and it should allow much nicer behaviour of the master
760
  daemon under load, and it also has uncovered some long-standing bugs
761
  related to the job serialisation (now fixed)
762
- Added a default iallocator setting to the cluster parameters,
763
  eliminating the need to always pass nodes or an iallocator for
764
  operations that require selection of new node(s)
765
- Added experimental support for the LXC virtualization method
766
- Added support for OS parameters, which allows the installation of
767
  instances to pass parameter to OS scripts in order to customise the
768
  instance
769
- Added a hypervisor parameter controlling the migration type (live or
770
  non-live), since hypervisors have various levels of reliability; this
771
  has renamed the 'live' parameter to 'mode'
772
- Added a cluster parameter ``reserved_lvs`` that denotes reserved
773
  logical volumes, meaning that cluster verify will ignore them and not
774
  flag their presence as errors
775
- The watcher will now reset the error count for failed instances after
776
  8 hours, thus allowing self-healing if the problem that caused the
777
  instances to be down/fail to start has cleared in the meantime
778
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
779
  check for, and warn, if the drbd module parameter ``usermode_helper``
780
  is not consistent with the cluster-wide setting; this is needed to
781
  make diagnose easier of failed drbd creations
782
- Started adding base IPv6 support, but this is not yet
783
  enabled/available for use
784
- Rename operations (cluster, instance) will now return the new name,
785
  which is especially useful if a short name was passed in
786
- Added support for instance migration in RAPI
787
- Added a tool to pre-configure nodes for the SSH setup, before joining
788
  them to the cluster; this will allow in the future a simplified model
789
  for node joining (but not yet fully enabled in 2.2); this needs the
790
  paramiko python library
791
- Fixed handling of name-resolving errors
792
- Fixed consistency of job results on the error path
793
- Fixed master-failover race condition when executed multiple times in
794
  sequence
795
- Fixed many bugs related to the job queue (mostly introduced during the
796
  2.2 development cycle, so not all are impacting 2.1)
797
- Fixed instance migration with missing disk symlinks
798
- Fixed handling of unknown jobs in ``gnt-job archive``
799
- And many other small fixes/improvements
800

    
801
Internal changes:
802

    
803
- Enhanced both the unittest and the QA coverage
804
- Switched the opcode validation to a generic model, and extended the
805
  validation to all opcode parameters
806
- Changed more parts of the code that write shell scripts to use the
807
  same class for this
808
- Switched the master daemon to use the asyncore library for the Luxi
809
  server endpoint
810

    
811

    
812
Version 2.2.0 beta 0
813
--------------------
814

    
815
*(Released Thu, 17 Jun 2010)*
816

    
817
- Added tool (``move-instance``) and infrastructure to move instances
818
  between separate clusters (see :doc:`separate documentation
819
  <move-instance>` and :doc:`design document <design-2.2>`)
820
- Added per-request RPC timeout
821
- RAPI now requires a Content-Type header for requests with a body (e.g.
822
  ``PUT`` or ``POST``) which must be set to ``application/json`` (see
823
  :rfc:`2616` (HTTP/1.1), section 7.2.1)
824
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
825
  reachable
826
- Implemented initial support for running Ganeti daemons as separate
827
  users, see configure-time flags ``--with-user-prefix`` and
828
  ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
829
  time)
830
- Instances can be removed after export (``gnt-backup export
831
  --remove-instance``)
832
- Self-signed certificates generated by Ganeti now use a 2048 bit RSA
833
  key (instead of 1024 bit)
834
- Added new cluster configuration file for cluster domain secret
835
- Import/export now use SSL instead of SSH
836
- Added support for showing estimated time when exporting an instance,
837
  see the ``ganeti-os-interface(7)`` manpage and look for
838
  ``EXP_SIZE_FD``
839

845

    
846
Some more bugfixes. Unless critical bugs occur, this will be the last
847
2.1 release:
848

    
849
- Fix case of MAC special-values
850
- Fix mac checker regex
851
- backend: Fix typo causing "out of range" error
852

Version 2.1.7
856
-------------
857

    
858
*(Released Tue, 24 Aug 2010)*

862
    (issue 113)
863
  - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)

Version 2.1.6
873
-------------
874

    
875
*(Released Fri, 16 Jul 2010)*
876

    
877
Bugfixes only:
878
  - Add an option to only select some reboot types during qa/burnin.
879
    (on some hypervisors consequent reboots are not supported)
880
  - Fix infrequent race condition in master failover. Sometimes the old
881
    master ip address would be still detected as up for a short time
882
    after it was removed, causing failover to fail.
883
  - Decrease mlockall warnings when the ctypes module is missing. On
884
    Python 2.4 we support running even if no ctypes module is installed,
885
    but we were too verbose about this issue.
886
  - Fix building on old distributions, on which man doesn't have a
887
    --warnings option.
888
  - Fix RAPI not to ignore the MAC address on instance creation
889
  - Implement the old instance creation format in the RAPI client.

A small bugfix release:
898
  - Fix disk adoption: broken by strict --disk option checking in 2.1.4
899
  - Fix batch-create: broken in the whole 2.1 series due to a lookup on
900
    a non-existing option
901
  - Fix instance create: the --force-variant option was ignored
902
  - Improve pylint 0.21 compatibility and warnings with Python 2.6

918
    versions which had fewer hypervisor parameters
919
  - Fix gnt-instance grow-disk on down instances
920
  - Fix an error-reporting bug during instance migration
921
  - Better checking of the ``--net`` and ``--disk`` values, to avoid
922
    silently ignoring broken ones
923
  - Fix an RPC error reporting bug affecting, for example, RAPI client
924
    users
925
  - Fix bug triggered by different API version os-es on different nodes
926
  - Fix a bug in instance startup with custom hvparams: OS level
927
    parameters would fail to be applied.
928
  - Fix the RAPI client under Python 2.6 (but more work is needed to
929
    make it work completely well with OpenSSL)
930
  - Fix handling of errors when resolving names from DNS
931

943

    
944
The node deamon now tries to mlock itself into memory, unless the
945
``--no-mlock`` flag is passed. It also doesn't fail if it can't write
946
its logs, and falls back to console logging. This allows emergency
947
features such as ``gnt-node powercycle`` to work even in the event of a
948
broken node disk (tested offlining the disk hosting the node's
949
filesystem and dropping its memory caches; don't try this at home)
950

    
951
KVM: add vhost-net acceleration support. It can be tested with a new
952
enough version of the kernel and of qemu-kvm.
953

    
954
KVM: Add instance chrooting feature. If you use privilege dropping for
955
your VMs you can also now force them to chroot to an empty directory,
956
before starting the emulated guest.
957

    
958
KVM: Add maximum migration bandwith and maximum downtime tweaking
959
support (requires a new-enough version of qemu-kvm).
960

    
961
Cluster verify will now warn if the master node doesn't have the master
962
ip configured on it.
963

    
964
Add a new (incompatible) instance creation request format to RAPI which
965
supports all parameters (previously only a subset was supported, and it
966
wasn't possible to extend the old format to accomodate all the new
967
features. The old format is still supported, and a client can check for
968
this feature, before using it, by checking for its presence in the
969
``features`` RAPI resource.
970

    
971
Now with ancient latin support. Try it passing the ``--roman`` option to
972
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
973
(requires the python-roman module to be installed, in order to work).
974

    
975
Other changes
976
~~~~~~~~~~~~~
977

    
978
As usual many internal code refactorings, documentation updates, and
979
such. Among others:
980

    
981
  - Lots of improvements and cleanups to the experimental Remote API
982
    (RAPI) client library.
983
  - A new unit test suite for the core daemon libraries.
984
  - A fix to creating missing directories makes sure the umask is not
985
    applied anymore. This enforces the same directory permissions
986
    everywhere.
987
  - Better handling terminating daemons with ctrl+c (used when running
988
    them in debugging mode).
989
  - Fix a race condition in live migrating a KVM instance, when stat()
990
    on the old proc status file returned EINVAL, which is an unexpected
991
    value.
992
  - Fixed manpage checking with newer man and utf-8 charachters. But now
993
    you need the en_US.UTF-8 locale enabled to build Ganeti from git.
994

Version 2.1.2.1
997
---------------
998

    
999
*(Released Fri, 7 May 2010)*
1000

    
1001
Fix a bug which prevented untagged KVM instances from starting.
1002

    
1003

    
1004
Version 2.1.2
1005
-------------
1006

    
1007
*(Released Fri, 7 May 2010)*
1008

    
1009
Another release with a long development cycle, during which many
1010
different features were added.
1011

    
1012
Significant features
1013
~~~~~~~~~~~~~~~~~~~~
1014

    
1015
The KVM hypervisor now can run the individual instances as non-root, to
1016
reduce the impact of a VM being hijacked due to bugs in the
1017
hypervisor. It is possible to run all instances as a single (non-root)
1018
user, to manually specify a user for each instance, or to dynamically
1019
allocate a user out of a cluster-wide pool to each instance, with the
1020
guarantee that no two instances will run under the same user ID on any
1021
given node.
1022

    
1023
An experimental RAPI client library, that can be used standalone
1024
(without the other Ganeti libraries), is provided in the source tree as
1025
``lib/rapi/client.py``. Note this client might change its interface in
1026
the future, as we iterate on its capabilities.
1027

    
1028
A new command, ``gnt-cluster renew-crypto`` has been added to easily
1029
replace the cluster's certificates and crypto keys. This might help in
1030
case they have been compromised, or have simply expired.
1031

    
1032
A new disk option for instance creation has been added that allows one
1033
to "adopt" currently existing logical volumes, with data
1034
preservation. This should allow easier migration to Ganeti from
1035
unmanaged (or managed via other software) instances.
1036

    
1037
Another disk improvement is the possibility to convert between redundant
1038
(DRBD) and plain (LVM) disk configuration for an instance. This should
1039
allow better scalability (starting with one node and growing the
1040
cluster, or shrinking a two-node cluster to one node).
1041

    
1042
A new feature that could help with automated node failovers has been
1043
implemented: if a node sees itself as offline (by querying the master
1044
candidates), it will try to shutdown (hard) all instances and any active
1045
DRBD devices. This reduces the risk of duplicate instances if an
1046
external script automatically failovers the instances on such nodes. To
1047
enable this, the cluster parameter ``maintain_node_health`` should be
1048
enabled; in the future this option (per the name) will enable other
1049
automatic maintenance features.
1050

    
1051
Instance export/import now will reuse the original instance
1052
specifications for all parameters; that means exporting an instance,
1053
deleting it and the importing it back should give an almost identical
1054
instance. Note that the default import behaviour has changed from
1055
before, where it created only one NIC; now it recreates the original
1056
number of NICs.
1057

    
1058
Cluster verify has added a few new checks: SSL certificates validity,
1059
/etc/hosts consistency across the cluster, etc.
1060

    
1061
Other changes
1062
~~~~~~~~~~~~~
1063

    
1064
As usual, many internal changes were done, documentation fixes,
1065
etc. Among others:
1066

    
1067
- Fixed cluster initialization with disabled cluster storage (regression
1068
  introduced in 2.1.1)
1069
- File-based storage supports growing the disks
1070
- Fixed behaviour of node role changes
1071
- Fixed cluster verify for some corner cases, plus a general rewrite of
1072
  cluster verify to allow future extension with more checks
1073
- Fixed log spamming by watcher and node daemon (regression introduced
1074
  in 2.1.1)
1075
- Fixed possible validation issues when changing the list of enabled
1076
  hypervisors
1077
- Fixed cleanup of /etc/hosts during node removal
1078
- Fixed RAPI response for invalid methods
1079
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
1080
- Multiple small improvements to the KVM hypervisor (VNC usage, booting
1081
  from ide disks, etc.)
1082
- Allow OS changes without re-installation (to record a changed OS
1083
  outside of Ganeti, or to allow OS renames)
1084
- Allow instance creation without OS installation (useful for example if
1085
  the OS will be installed manually, or restored from a backup not in
1086
  Ganeti format)
1087
- Implemented option to make cluster ``copyfile`` use the replication
1088
  network
1089
- Added list of enabled hypervisors to ssconf (possibly useful for
1090
  external scripts)
1091
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
1092
  1.2 clusters
1093
- A partial form of node re-IP is possible via node readd, which now
1094
  allows changed node primary IP
1095
- Command line utilities now show an informational message if the job is
1096
  waiting for a lock
1097
- The logs of the master daemon now show the PID/UID/GID of the
1098
  connected client
1099

1101
Version 2.1.1
1102
-------------
1103

    
1104
*(Released Fri, 12 Mar 2010)*
1105

    
1106
During the 2.1.0 long release candidate cycle, a lot of improvements and
1107
changes have accumulated with were released later as 2.1.1.
1108

    
1109
Major changes
1110
~~~~~~~~~~~~~
1111

    
1112
The node evacuate command (``gnt-node evacuate``) was significantly
1113
rewritten, and as such the IAllocator protocol was changed - a new
1114
request type has been added. This unfortunate change during a stable
1115
series is designed to improve performance of node evacuations; on
1116
clusters with more than about five nodes and which are well-balanced,
1117
evacuation should proceed in parallel for all instances of the node
1118
being evacuated. As such, any existing IAllocator scripts need to be
1119
updated, otherwise the above command will fail due to the unknown
1120
request. The provided "dumb" allocator has not been updated; but the
1121
ganeti-htools package supports the new protocol since version 0.2.4.
1122

    
1123
Another important change is increased validation of node and instance
1124
names. This might create problems in special cases, if invalid host
1125
names are being used.
1126

    
1127
Also, a new layer of hypervisor parameters has been added, that sits at
1128
OS level between the cluster defaults and the instance ones. This allows
1129
customisation of virtualization parameters depending on the installed
1130
OS. For example instances with OS 'X' may have a different KVM kernel
1131
(or any other parameter) than the cluster defaults. This is intended to
1132
help managing a multiple OSes on the same cluster, without manual
1133
modification of each instance's parameters.
1134

    
1135
A tool for merging clusters, ``cluster-merge``, has been added in the
1136
tools sub-directory.
1137

    
1138
Bug fixes
1139
~~~~~~~~~
1140

    
1141
- Improved the int/float conversions that should make the code more
1142
  robust in face of errors from the node daemons
1143
- Fixed the remove node code in case of internal configuration errors
1144
- Fixed the node daemon behaviour in face of inconsistent queue
1145
  directory (e.g. read-only file-system where we can't open the files
1146
  read-write, etc.)
1147
- Fixed the behaviour of gnt-node modify for master candidate demotion;
1148
  now it either aborts cleanly or, if given the new "auto_promote"
1149
  parameter, will automatically promote other nodes as needed
1150
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
1151
  completely prevent Ganeti from working
1152
- Fixed bug for instance export when not all disks were successfully
1153
  exported
1154
- Fixed behaviour of node add when the new node is slow in starting up
1155
  the node daemon
1156
- Fixed handling of signals in the LUXI client, which should improve
1157
  behaviour of command-line scripts
1158
- Added checks for invalid node/instance names in the configuration (now
1159
  flagged during cluster verify)
1160
- Fixed watcher behaviour for disk activation errors
1161
- Fixed two potentially endless loops in http library, which led to the
1162
  RAPI daemon hanging and consuming 100% CPU in some cases
1163
- Fixed bug in RAPI daemon related to hashed passwords
1164
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM
1165
  instances
1166
- Enhanced compatibility with non-Debian OSes, but not using absolute
1167
  path in some commands and allowing customisation of the ssh
1168
  configuration directory
1169
- Fixed possible future issue with new Python versions by abiding to the
1170
  proper use of ``__slots__`` attribute on classes
1171
- Added checks that should prevent directory traversal attacks
1172
- Many documentation fixes based on feedback from users
1173

    
1174
New features
1175
~~~~~~~~~~~~
1176

    
1177
- Added an "early_release" more for instance replace disks and node
1178
  evacuate, where we release locks earlier and thus allow higher
1179
  parallelism within the cluster
1180
- Added watcher hooks, intended to allow the watcher to restart other
1181
  daemons (e.g. from the ganeti-nbma project), but they can be used of
1182
  course for any other purpose
1183
- Added a compile-time disable for DRBD barriers, to increase
1184
  performance if the administrator trusts the power supply or the
1185
  storage system to not lose writes
1186
- Added the option of using syslog for logging instead of, or in
1187
  addition to, Ganeti's own log files
1188
- Removed boot restriction for paravirtual NICs for KVM, recent versions
1189
  can indeed boot from a paravirtual NIC
1190
- Added a generic debug level for many operations; while this is not
1191
  used widely yet, it allows one to pass the debug value all the way to
1192
  the OS scripts
1193
- Enhanced the hooks environment for instance moves (failovers,
1194
  migrations) where the primary/secondary nodes changed during the
1195
  operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
1196
- Enhanced data validations for many user-supplied values; one important
1197
  item is the restrictions imposed on instance and node names, which
1198
  might reject some (invalid) host names
1199
- Add a configure-time option to disable file-based storage, if it's not
1200
  needed; this allows greater security separation between the master
1201
  node and the other nodes from the point of view of the inter-node RPC
1202
  protocol
1203
- Added user notification in interactive tools if job is waiting in the
1204
  job queue or trying to acquire locks
1205
- Added log messages when a job is waiting for locks
1206
- Added filtering by node tags in instance operations which admit
1207
  multiple instances (start, stop, reboot, reinstall)
1208
- Added a new tool for cluster mergers, ``cluster-merge``
1209
- Parameters from command line which are of the form ``a=b,c=d`` can now
1210
  use backslash escapes to pass in values which contain commas,
1211
  e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
1212
  ``b,c``
1213
- For KVM, the instance name is the first parameter passed to KVM, so
1214
  that it's more visible in the process list
1215

    
1216

    
1217
Version 2.1.0
1218
-------------
1219

    
1220
*(Released Tue, 2 Mar 2010)*
1221

    
1222
Ganeti 2.1 brings many improvements with it. Major changes:
1223

    
1224
- Added infrastructure to ease automated disk repairs
1225
- Added new daemon to export configuration data in a cheaper way than
1226
  using the remote API
1227
- Instance NICs can now be routed instead of being associated with a
1228
  networking bridge
1229
- Improved job locking logic to reduce impact of jobs acquiring multiple
1230
  locks waiting for other long-running jobs
1231

    
1232
In-depth implementation details can be found in the Ganeti 2.1 design
1233
document.

- Added a ``gnt-job watch`` command that allows following the ouput of a
1377
  job
1378
- Added a bind-address option to ganeti-rapi
1379
- Added more checks to the configuration verify
1380
- Enhanced the burnin script such that some operations can be retried
1381
  automatically
1382
- Converted instance reinstall to multi-instance model
1383

    
1384

    
1385
Version 2.0.3
1386
-------------
1387

    
1388
*(Released Fri, 7 Aug 2009)*
1389

    
1390
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1391
  to allow using the pre-2.0.2 behaviour in activation, if any existing
1392
  instances have mismatched disk sizes in the configuration
1393
- Added ``gnt-cluster repair-disk-sizes`` command to check and update
1394
  any configuration mismatches for disk sizes
1395
- Added ``gnt-master cluste-failover --no-voting`` to allow master
1396
  failover to work on two-node clusters
1397
- Fixed the ``--net`` option of ``gnt-backup import``, which was
1398
  unusable
1399
- Fixed detection of OS script errors in ``gnt-backup export``
1400
- Fixed exit code of ``gnt-backup export``
1401

    
1402

    
1403
Version 2.0.2
1404
-------------
1405

    
1406
*(Released Fri, 17 Jul 2009)*
1407

    
1408
- Added experimental support for stripped logical volumes; this should
1409
  enhance performance but comes with a higher complexity in the block
1410
  device handling; stripping is only enabled when passing
1411
  ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1412
  affected even in the non-stripped mode
1413
- Improved resiliency against transient failures at the end of DRBD
1414
  resyncs, and in general of DRBD resync checks
1415
- Fixed a couple of issues with exports and snapshot errors
1416
- Fixed a couple of issues in instance listing
1417
- Added display of the disk size in ``gnt-instance info``
1418
- Fixed checking for valid OSes in instance creation
1419
- Fixed handling of the "vcpus" parameter in instance listing and in
1420
  general of invalid parameters
1421
- Fixed http server library, and thus RAPI, to handle invalid
1422
  username/password combinations correctly; this means that now they
1423
  report unauthorized for queries too, not only for modifications,
1424
  allowing earlier detect of configuration problems
1425
- Added a new "role" node list field, equivalent to the master/master
1426
  candidate/drained/offline flags combinations
1427
- Fixed cluster modify and changes of candidate pool size
1428
- Fixed cluster verify error messages for wrong files on regular nodes
1429
- Fixed a couple of issues with node demotion from master candidate role
1430
- Fixed node readd issues
1431
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1432
- Added a new ``--no-voting`` option for masterfailover to fix failover
1433
  on two-nodes clusters when the former master node is unreachable
1434
- Added instance reinstall over RAPI
1435

    
1436

    
1437
Version 2.0.1
1438
-------------
1439

    
1440
*(Released Tue, 16 Jun 2009)*
1441

    
1442
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1443
  allow re-adding the start in single-user option (regression from 1.2)
1444
- the watcher writes the instance status to a file, to allow monitoring
1445
  to report the instance status (from the master) based on cached
1446
  results of the watcher's queries; while this can get stale if the
1447
  watcher is being locked due to other work on the cluster, this is
1448
  still an improvement
1449
- the watcher now also restarts the node daemon and the rapi daemon if
1450
  they died
1451
- fixed the watcher to handle full and drained queue cases
1452
- hooks export more instance data in the environment, which helps if
1453
  hook scripts need to take action based on the instance's properties
1454
  (no longer need to query back into ganeti)
1455
- instance failovers when the instance is stopped do not check for free
1456
  RAM, so that failing over a stopped instance is possible in low memory
1457
  situations
1458
- rapi uses queries for tags instead of jobs (for less job traffic), and
1459
  for cluster tags it won't talk to masterd at all but read them from
1460
  ssconf
1461
- a couple of error handling fixes in RAPI
1462
- drbd handling: improved the error handling of inconsistent disks after
1463
  resync to reduce the frequency of "there are some degraded disks for
1464
  this instance" messages
1465
- fixed a bug in live migration when DRBD doesn't want to reconnect (the
1466
  error handling path called a wrong function name)
1467

    
1468

    
1469
Version 2.0.0 final
1470
-------------------
1471

    
1472
*(Released Wed, 27 May 2009)*
1473

    
1474
- no changes from rc5
1475

1478
-------------------------------
1479

    
1480
*(Released Wed, 20 May 2009)*
1481

    
1482
- fix a couple of bugs (validation, argument checks)
1483
- fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1484
- some small improvements to RAPI and IAllocator
1485
- make watcher automatically start the master daemon if down
1486

    
1487

    
1488
Version 2.0 release candidate 4
1489
-------------------------------
1490

    
1491
*(Released Mon, 27 Apr 2009)*
1492

    
1493
- change the OS list to not require locks; this helps with big clusters
1494
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1495
  volume group is broken
1496
- ``gnt-instance info``, without any arguments, doesn't run for all
1497
  instances anymore; either pass ``--all`` or pass the desired
1498
  instances; this helps against mistakes on big clusters where listing
1499
  the information for all instances takes a long time
1500
- miscellaneous doc and man pages fixes
1501

    
1502

    
1503
Version 2.0 release candidate 3
1504
-------------------------------
1505

    
1506
*(Released Wed, 8 Apr 2009)*
1507

    
1508
- Change the internal locking model of some ``gnt-node`` commands, in
1509
  order to reduce contention (and blocking of master daemon) when
1510
  batching many creation/reinstall jobs
1511
- Fixes to Xen soft reboot
1512
- No longer build documentation at build time, instead distribute it in
1513
  the archive, in order to reduce the need for the whole docbook/rst
1514
  toolchains
1515

    
1516

    
1517
Version 2.0 release candidate 2
1518
-------------------------------
1519

    
1520
*(Released Fri, 27 Mar 2009)*
1521

    
1522
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1523
- Fix watcher startup sequence, improves the behaviour of busy clusters
1524
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1525
  replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1526
  bind address and other places
1527
- Some documentation fixes and updates
1528

    
1529

    
1530
Version 2.0 release candidate 1
1531
-------------------------------
1532

    
1533
*(Released Mon, 2 Mar 2009)*
1534

    
1535
- More documentation updates, now all docs should be more-or-less
1536
  up-to-date
1537
- A couple of small fixes (mixed hypervisor clusters, offline nodes,
1538
  etc.)
1539
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1540
  and KVM)
1541
- Fix an issue related to $libdir/run/ganeti and cluster creation
1542

    
1543

    
1544
Version 2.0 beta 2
1545
------------------
1546

    
1547
*(Released Thu, 19 Feb 2009)*
1548

    
1549
- Xen PVM and KVM have switched the default value for the instance root
1550
  disk to the first partition on the first drive, instead of the whole
1551
  drive; this means that the OS installation scripts must be changed
1552
  accordingly
1553
- Man pages have been updated
1554
- RAPI has been switched by default to HTTPS, and the exported functions
1555
  should all work correctly
1556
- RAPI v1 has been removed
1557
- Many improvements to the KVM hypervisor
1558
- Block device errors are now better reported
1559
- Many other bugfixes and small improvements
1560

    
1561

    
1562
Version 2.0 beta 1
1563
------------------
1564

    
1565
*(Released Mon, 26 Jan 2009)*
1566

    
1567
- Version 2 is a general rewrite of the code and therefore the
1568
  differences are too many to list, see the design document for 2.0 in
1569
  the ``doc/`` subdirectory for more details
1570
- In this beta version there is not yet a migration path from 1.2 (there
1571
  will be one in the final 2.0 release)
1572
- A few significant changes are:
1573

    
1574
  - all commands are executed by a daemon (``ganeti-masterd``) and the
1575
    various ``gnt-*`` commands are just front-ends to it
1576
  - all the commands are entered into, and executed from a job queue,
1577
    see the ``gnt-job(8)`` manpage
1578
  - the RAPI daemon supports read-write operations, secured by basic
1579
    HTTP authentication on top of HTTPS
1580
  - DRBD version 0.7 support has been removed, DRBD 8 is the only
1581
    supported version (when migrating from Ganeti 1.2 to 2.0, you need
1582
    to migrate to DRBD 8 first while still running Ganeti 1.2)
1583
  - DRBD devices are using statically allocated minor numbers, which
1584
    will be assigned to existing instances during the migration process
1585
  - there is support for both Xen PVM and Xen HVM instances running on
1586
    the same cluster
1587
  - KVM virtualization is supported too
1588
  - file-based storage has been implemented, which means that it is
1589
    possible to run the cluster without LVM and DRBD storage, for
1590
    example using a shared filesystem exported from shared storage (and
1591
    still have live migration)
1592

    
1593

    
1594
Version 1.2.7
1595
-------------
1596

    
1597
*(Released Tue, 13 Jan 2009)*
1598

    
1599
- Change the default reboot type in ``gnt-instance reboot`` to "hard"
1600
- Reuse the old instance mac address by default on instance import, if
1601
  the instance name is the same.
1602
- Handle situations in which the node info rpc returns incomplete
1603
  results (issue 46)
1604
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1605
- Improved version of batcher:
1606

    
1607
  - state file support
1608
  - instance mac address support
1609
  - support for HVM clusters/instances
1610

    
1611
- Add an option to show the number of cpu sockets and nodes in
1612
  ``gnt-node list``
1613
- Support OSes that handle more than one version of the OS api (but do
1614
  not change the current API in any other way)
1615
- Fix ``gnt-node migrate``
1616
- ``gnt-debug`` man page
1617
- Fixes various more typos and small issues
1618
- Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1619

    
1620

    
1621
Version 1.2.6
1622
-------------
1623

    
1624
*(Released Wed, 24 Sep 2008)*
1625

    
1626
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1627
  type of disk exported to fully virtualized instances.
1628
- provide access to the serial console of HVM instances
1629
- instance auto_balance flag, set by default. If turned off it will
1630
  avoid warnings on cluster verify if there is not enough memory to fail
1631
  over an instance. in the future it will prevent automatically failing
1632
  it over when we will support that.
1633
- batcher tool for instance creation, see ``tools/README.batcher``
1634
- ``gnt-instance reinstall --select-os`` to interactively select a new
1635
  operating system when reinstalling an instance.
1636
- when changing the memory amount on instance modify a check has been
1637
  added that the instance will be able to start. also warnings are
1638
  emitted if the instance will not be able to fail over, if auto_balance
1639
  is true.
1640
- documentation fixes
1641
- sync fields between ``gnt-instance list/modify/add/import``
1642
- fix a race condition in drbd when the sync speed was set after giving
1643
  the device a remote peer.
1644

    
1645

    
1646
Version 1.2.5
1647
-------------
1648

    
1649
*(Released Tue, 22 Jul 2008)*
1650

    
1651
- note: the allowed size and number of tags per object were reduced
1652
- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1653
- fixed twisted 8.x compatibility
1654
- fixed ``gnt-instance replace-disks`` with iallocator
1655
- add TCP keepalives on twisted connections to detect restarted nodes
1656
- disk increase support, see ``gnt-instance grow-disk``
1657
- implement bulk node/instance query for RAPI
1658
- add tags in node/instance listing (optional)
1659
- experimental migration (and live migration) support, read the man page
1660
  for ``gnt-instance migrate``
1661
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1662
  has some small improvements in handling its state file
1663

    
1664

    
1665
Version 1.2.4
1666
-------------
1667

    
1668
*(Released Fri, 13 Jun 2008)*
1669

    
1670
- Experimental readonly, REST-based remote API implementation;
1671
  automatically started on master node, TCP port 5080, if enabled by
1672
  ``--enable-rapi`` parameter to configure script.
1673
- Instance allocator support. Add and import instance accept a
1674
  ``--iallocator`` parameter, and call that instance allocator to decide
1675
  which node to use for the instance. The iallocator document describes
1676
  what's expected from an allocator script.
1677
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1678
  ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1679
  node is lost there is still enough memory to fail over the instances
1680
  that reside on it.
1681
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1682
  ``gnt-cluster verify``, to check for site-specific compliance. All the
1683
  hooks will run, and their output, if any, will be displayed. Any
1684
  failing hook will make the verification return an error value.
1685
- ``gnt-cluster verify`` now checks that its peers are reachable on the
1686
  primary and secondary interfaces
1687
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1688
  that is still declared as part of the cluster and has failed.
1689
- ``gnt-* list`` commands now accept a new ``-o +field`` way of
1690
  specifying output fields, that just adds the chosen fields to the
1691
  default ones.
1692
- ``gnt-backup`` now has a new ``remove`` command to delete an existing
1693
  export from the filesystem.
1694
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1695
  have been added. Using them you can enable/disable acpi and pae
1696
  support, and specify a path for a cd image to be exported to the
1697
  instance. These parameters as the name suggest only work on HVM
1698
  clusters.
1699
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1700
  PAE support will be set to the previously hardcoded values, but the
1701
  (previously hardcoded) path to the CDROM ISO image will be unset and
1702
  if required, needs to be set manually with ``gnt-instance modify``
1703
  after the upgrade.
1704
- The address to which an instance's VNC console is bound is now
1705
  selectable per-instance, rather than being cluster wide. Of course
1706
  this only applies to instances controlled via VNC, so currently just
1707
  applies to HVM clusters.
1708

    
1709

    
1710
Version 1.2.3
1711
-------------
1712

    
1713
*(Released Mon, 18 Feb 2008)*
1714

    
1715
- more tweaks to the disk activation code (especially helpful for DRBD)
1716
- change the default ``gnt-instance list`` output format, now there is
1717
  one combined status field (see the manpage for the exact values this
1718
  field will have)
1719
- some more fixes for the mac export to hooks change
1720
- make Ganeti not break with DRBD 8.2.x (which changed the version
1721
  format in ``/proc/drbd``) (issue 24)
1722
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1723
  template, allowing migration from DRBD0.7+MD to DRBD8
1724

    
1725

    
1726
Version 1.2.2
1727
-------------

1732
  support (issue 23)
1733
- add command aliases infrastructure and a few aliases
1734
- allow listing of VCPUs in the ``gnt-instance list`` and improve the
1735
  man pages and the ``--help`` option of ``gnt-node
1736
  list``/``gnt-instance list``
1737
- fix ``gnt-backup list`` with down nodes (issue 21)
1738
- change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1739
- fix the dist archive and add a check for including svn/git files in
1740
  the future
1741
- some developer-related changes: improve the burnin and the QA suite,
1742
  add an upload script for testing during development
1743

    
1744

1751
  "Initializing the cluster"
1752
- allow for the PVM hypervisor per-instance kernel and initrd paths
1753
- add a new command ``gnt-cluster verify-disks`` which uses a new
1754
  algorithm to improve the reconnection of the DRBD pairs if the device
1755
  on the secondary node has gone away
1756
- make logical volume code auto-activate LVs at disk activation time
1757
- slightly improve the speed of activating disks
1758

1767

    
1768
*(Released Tue, 4 Dec 2007)*
1769

    
1770
- Log the ``xm create`` output to the node daemon log on failure (to
1771
  help diagnosing the error)
1772
- In debug mode, log all external commands output if failed to the logs
1773
- Change parsing of lvm commands to ignore stderr
1774

    
1775

    
1776
Version 1.2b3
1777
-------------
1778

    
1779
*(Released Wed, 28 Nov 2007)*
1780

    
1781

Version 1.2b2
1789
-------------
1790

    
1791
*(Released Tue, 13 Nov 2007)*
1792

    
1793
- Change configuration file format from Python's Pickle to JSON.
1794
  Upgrading is possible using the cfgupgrade utility.
1795
- Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1796
  faster replace disks and is more stable (DRBD 8 has many improvements
1797
  compared to DRBD 0.7)
1798
- Added command line tags support (see man pages for ``gnt-instance``,
1799
  ``gnt-node``, ``gnt-cluster``)
1800
- Added instance rename support
1801
- Added multi-instance startup/shutdown
1802
