Incompatible/important changes and bugfixes
11
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
12

    
13
- The default of the ``/2/instances/[instance_name]/rename`` RAPI
14
  resource's ``ip_check`` parameter changed from ``True`` to ``False``
15
  to match the underlying LUXI interface.
16
- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use
17
  body parameters, see :doc:`RAPI documentation <rapi>`. The server does
18
  not maintain backwards-compatibility as the underlying operation
19
  changed in an incompatible way. The RAPI client can talk to old
20
  servers, but it needs to be told so as the return value changed.
21
- When creating file-based instances via RAPI, the ``file_driver``
22
  parameter no longer defaults to ``loop`` and must be specified.
23
- The deprecated ``bridge`` NIC parameter is no longer supported. Use
24
  ``link`` instead.
25
- Support for the undocumented and deprecated RAPI instance creation
26
  request format version 0 has been dropped. Use version 1, supported
27
  since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
28
- Pyparsing 1.4.6 or above is required, see :doc:`installation
29
  documentation <install>`.
30
- The "cluster-verify" hooks are now executed per group by the
31
  ``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior
32
  if you just run ``gnt-cluster verify``, which generates one opcode per
33
  group.
34
- The environment as passed to the OS scripts is cleared, and thus no
35
  environment variables defined in the node daemon's environment will be
36
  inherited by the scripts.
37
- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been
38
  deprecated.
39
- :doc:`New iallocator modes <design-multi-reloc>` have been added to
40
  support operations involving multiple node groups.
41
- Offline nodes are ignored when failing over an instance.
42
- Support for KVM version 1.0, which changed the version reporting format
43
  from 3 to 2 digits.
44
- ``Makefile`` is now compatible with Automake 1.11.2
45
- Includes all bugfixes made in the 2.4 series
46

    
47
New features
48
~~~~~~~~~~~~
49

    
50
- The ganeti-htools project has been merged into the ganeti-core source
51
  tree and will be built as part of Ganeti (see :doc:`install-quick`).
52
- Implemented support for :doc:`shared storage <design-shared-storage>`.
53
- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting
54
  GPT-style partition tables (requires `parted
55
  <http://www.gnu.org/s/parted/>`_).
56
- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor.
57
- Allowed adding tags on instance creation.
58
- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`)
59
- Allow instances to be started in a paused state, enabling the user to
60
  see the complete console output on boot using the console.
61
- Added new hypervisor flag to control default reboot behaviour
62
  (``reboot_behavior``).
63
- Added support for KVM keymaps (hypervisor parameter ``keymap``).
64
- Improved out-of-band management support:
65

    
66
  - Added ``gnt-node health`` command reporting the health status of
67
    nodes.
68
  - Added ``gnt-node power`` command to manage power status of nodes.
69
  - Added command for emergency power-off (EPO), ``gnt-cluster epo``.
70

    
71
- Instance migration can fall back to failover if instance is not
72
  running.
73
- Filters can be used when listing nodes, instances, groups and locks;
74
  see *ganeti(7)* manpage.
75
- Added post-execution status as variables to :doc:`hooks <hooks>`
76
  environment.
77
- Instance tags are exported/imported together with the instance.
78
- When given an explicit job ID, ``gnt-job info`` will work for archived
79
  jobs.
80
- Jobs can define dependencies on other jobs (not yet supported via
81
  RAPI or command line, but used by internal commands and usable via
82
  LUXI).
83

    
84
  - Lock monitor (``gnt-debug locks``) shows jobs waiting for
85
    dependencies.
86

    
87
- Instance failover is now available as a RAPI resource
88
  (``/2/instances/[instance_name]/failover``).
89
- ``gnt-instance info`` defaults to static information if primary node
90
  is offline.
91
- Opcodes have a new ``comment`` attribute.
92
- Added basic SPICE support to KVM hypervisor.
93
- ``tools/ganeti-listrunner`` allows passing of arguments to executable.
94

    
95
Node group improvements
96
~~~~~~~~~~~~~~~~~~~~~~~
97

    
98
- ``gnt-cluster verify`` has been modified to check groups separately,
99
  thereby improving performance.
100
- Node group support has been added to ``gnt-cluster verify-disks``,
101
  which now operates per node group.
102
- Watcher has been changed to work better with node groups.
103

    
104
  - One process and state file per node group.
105
  - Slow watcher in one group doesn't block other group's watcher.
106

    
107
- Added new command, ``gnt-group evacuate``, to move all instances in a
108
  node group to other groups.
109
- Added ``gnt-instance change-group`` to move an instance to another
110
  node group.
111
- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support
112
  per-group operations.
113
- Node groups can be tagged.
114
- Some operations switch from an exclusive to a shared lock as soon as
115
  possible.
116
- Instance's primary and secondary nodes' groups are now available as
117
  query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group``
118
  and ``snodes.group.uuid``).
119

    
120
Misc
121
~~~~
122

    
123
- Numerous updates to documentation and manpages.
124

    
125
  - :doc:`RAPI <rapi>` documentation now has detailed parameter
126
    descriptions.
127
  - Some opcode/job results are now also documented, see :doc:`RAPI
128
    <rapi>`.
129

    
130
- A lockset's internal lock is now also visible in lock monitor.
131
- Log messages from job queue workers now contain information about the
132
  opcode they're processing.
133
- ``gnt-instance console`` no longer requires the instance lock.
134
- A short delay when waiting for job changes reduces the number of LUXI
135
  requests significantly.
136
- DRBD metadata volumes are overwritten with zeros during disk creation.
137
- ``devel/upload`` now uses correct permissions for directories.
138

231

    
232
*(Released Fri, 5 Aug 2011)*
233

    
234
Many bug-fixes and a few small features:
235

    
236
- Fixed argument order in ``ReserveLV`` and ``ReserveMAC`` which caused
237
  issues when you tried to add an instance with two MAC addresses in one
238
  request
239
- KVM: fixed per-instance stored UID value
240
- KVM: configure bridged NICs at migration start
241
- KVM: Fix a bug where instance will not start with never KVM versions
242
  (>= 0.14)
243
- Added OS search path to ``gnt-cluster info``
244
- Fixed an issue with ``file_storage_dir`` where you were forced to
245
  provide an absolute path, but the documentation states it is a
246
  relative path, the documentation was right
247
- Added a new parameter to instance stop/start called ``--no-remember``
248
  that will make the state change to not be remembered
249
- Implemented ``no_remember`` at RAPI level
250
- Improved the documentation
251
- Node evacuation: don't call IAllocator if node is already empty
252
- Fixed bug in DRBD8 replace disks on current nodes
253
- Fixed bug in recreate-disks for DRBD instances
254
- Moved assertion checking locks in ``gnt-instance replace-disks``
255
  causing it to abort with not owning the right locks for some situation
256
- Job queue: Fixed potential race condition when cancelling queued jobs
257
- Fixed off-by-one bug in job serial generation
258
- ``gnt-node volumes``: Fix instance names

263

    
264

    
265
Version 2.4.2
266
-------------
267

    
268
*(Released Thu, 12 May 2011)*
269

    
270
Many bug-fixes and a few new small features:
271

    
272
- Fixed a bug related to log opening failures
273
- Fixed a bug in instance listing with orphan instances
274
- Fixed a bug which prevented resetting the cluster-level node parameter
275
  ``oob_program`` to the default
276
- Many fixes related to the ``cluster-merge`` tool
277
- Fixed a race condition in the lock monitor, which caused failures
278
  during (at least) creation of many instances in parallel
279
- Improved output for gnt-job info
280
- Removed the quiet flag on some ssh calls which prevented debugging
281
  failures
282
- Improved the N+1 failure messages in cluster verify by actually
283
  showing the memory values (needed and available)
284
- Increased lock attempt timeouts so that when executing long operations
285
  (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire'
286
  too early and thus prevent the use of the 'fair' mechanism
287
- Changed instance query data (``gnt-instance info``) to not acquire
288
  locks unless needed, thus allowing its use on locked instance if only
289
  static information is asked for
290
- Improved behaviour with filesystems that do not support rename on an
291
  opened file
292
- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which
293
  kept locks on all nodes during the wipe, which is unneeded
294
- Fixed ``gnt-watcher`` handling of errors during hooks execution
295
- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than
296
  10GiB) which caused the wipe to fail right at the end in some cases
297
- Fixed master IP activation when doing master failover with no-voting
298
- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of
299
  the master node itself
300
- Fixed potential data-loss in under disk full conditions, where Ganeti
301
  wouldn't check correctly the return code and would consider
302
  partially-written files 'correct'
303
- Fixed bug related to multiple VGs and DRBD disk replacing
304
- Added new disk parameter ``metavg`` that allows placement of the meta
305
  device for DRBD in a different volume group
306
- Fixed error handling in the node daemon when the system libc doesn't
307
  have major number 6 (i.e. if ``libc.so.6`` is not the actual libc)
308
- Fixed lock release during replace-disks, which kept cluster-wide locks
309
  when doing disk replaces with an iallocator script
310
- Added check for missing bridges in cluster verify
311
- Handle EPIPE errors while writing to the terminal better, so that
312
  piping the output to e.g. ``less`` doesn't cause a backtrace
313
- Fixed rare case where a ^C during Luxi calls could have been
314
  interpreted as server errors, instead of simply terminating
315
- Fixed a race condition in LUGroupAssignNodes (``gnt-group
316
  assign-nodes``)
317
- Added a few more parameters to the KVM hypervisor, allowing a second
318
  CDROM, custom disk type for CDROMs and a floppy image
319
- Removed redundant message in instance rename when the name is given
320
  already as a FQDN
321
- Added option to ``gnt-instance recreate-disks`` to allow creating the
322
  disks on new nodes, allowing recreation when the original instance
323
  nodes are completely gone
324
- Added option when converting disk templates to DRBD to skip waiting
325
  for the resync, in order to make the instance available sooner
326
- Added two new variables to the OS scripts environment (containing the
327
  instance's nodes)
328
- Made the root_path and optional parameter for the xen-pvm hypervisor,
329
  to allow use of ``pvgrub`` as bootloader
330
- Changed the instance memory modifications to only check out-of-memory
331
  conditions on memory increases, and turned the secondary node warnings
332
  into errors (they can still be overridden via ``--force``)
333
- Fixed the handling of a corner case when the Python installation gets
334
  corrupted (e.g. a bad disk) while ganeti-noded is running and we try
335
  to execute a command that doesn't exist
336
- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary
337
  node of the instance returned failures during instance shutdown; this
338
  adds the option ``--ignore-consistency`` to gnt-instance move
339

    
340
And as usual, various improvements to the error messages, documentation
341
and man pages.
342

    
343
Version 2.4.1
344
-------------
345

    
346
*(Released Wed, 09 Mar 2011)*
347

    
348
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
349
the RAPI users file if run twice (even with ``--dry-run``).
350

    
351
The release fixes that bug (nothing else changed).
352

    
353

    
354
Version 2.4.0
355
-------------
356

    
357
*(Released Mon, 07 Mar 2011)*
358

    
359
Final 2.4.0 release. Just a few small fixes:
360

    
361
- Fixed RAPI node evacuate
362
- Fixed the kvm-ifup script
363
- Fixed internal error handling for special job cases
364
- Updated man page to specify the escaping feature for options
365

    
366

    
367
Version 2.4.0 rc3
368
-----------------
369

    
370
*(Released Mon, 28 Feb 2011)*
371

    
372
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
373
that this feature wiped the disks of the wrong instance, leading to loss
374
of data.
375

    
376
Other changes:
377

    
378
- Fixed title of query field containing instance name
379
- Expanded the glossary in the documentation
380
- Fixed one unittest (internal issue)
381

    
382

    
383
Version 2.4.0 rc2
384
-----------------
385

    
386
*(Released Mon, 21 Feb 2011)*
387

    
388
A number of bug fixes plus just a couple functionality changes.
389

    
390
On the user-visible side, the ``gnt-* list`` command output has changed
391
with respect to "special" field states. The current rc1 style of display
392
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
393
the default output mode special fields states are displayed as follows:
394

    
395
- Offline resource: ``*``
396
- Unavailable/not applicable: ``-``
397
- Data missing (RPC failure): ``?``
398
- Unknown field: ``??``
399

    
400
Another user-visible change is the addition of ``--force-join`` to
401
``gnt-node add``.
402

    
403
As for bug fixes:
404

    
405
- ``tools/cluster-merge`` has seen many fixes and is now enabled again
406
- Fixed regression in RAPI/instance reinstall where all parameters were
407
  required (instead of optional)
408
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
409
- Fixed iallocator usage (offline nodes were not considered offline)
410
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes
411
- Fixed hypervisor and OS parameter validation with respect to
412
  non-vm_capable nodes
413
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
414
  cosmetic)
415
- Fixed ``tools/listrunner`` with respect to agent-based usage
416

    
417

    
418
Version 2.4.0 rc1
419
-----------------
420

    
421
*(Released Fri,  4 Feb 2011)*
422

    
423
Many changes and fixes since the beta1 release. While there were some
424
internal changes, the code has been mostly stabilised for the RC
425
release.
426

    
427
Note: the dumb allocator was removed in this release, as it was not kept
428
up-to-date with the IAllocator protocol changes. It is recommended to
429
use the ``hail`` command from the ganeti-htools package.
430

    
431
Note: the 2.4 and up versions of Ganeti are not compatible with the
432
0.2.x branch of ganeti-htools. You need to upgrade to
433
ganeti-htools-0.3.0 (or later).
434

    
435
Regressions fixed from 2.3
436
~~~~~~~~~~~~~~~~~~~~~~~~~~
437

    
438
- Fixed the ``gnt-cluster verify-disks`` command
439
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to
440
  serially on nodes)
441
- Fixed disk adoption breakage
442
- Fixed wrong headers in instance listing for field aliases
443

    
444
Other bugs fixed
445
~~~~~~~~~~~~~~~~
446

    
447
- Fixed corner case in KVM handling of NICs
448
- Fixed many cases of wrong handling of non-vm_capable nodes
449
- Fixed a bug where a missing instance symlink was not possible to
450
  recreate with any ``gnt-*`` command (now ``gnt-instance
451
  activate-disks`` does it)
452
- Fixed the volume group name as reported by ``gnt-cluster
453
  verify-disks``
454
- Increased timeouts for the import-export code, hopefully leading to
455
  fewer aborts due network or instance timeouts
456
- Fixed bug in ``gnt-node list-storage``
457
- Fixed bug where not all daemons were started on cluster
458
  initialisation, but only at the first watcher run
459
- Fixed many bugs in the OOB implementation
460
- Fixed watcher behaviour in presence of instances with offline
461
  secondaries
462
- Fixed instance list output for instances running on the wrong node
463
- a few fixes to the cluster-merge tool, but it still cannot merge
464
  multi-node groups (currently it is not recommended to use this tool)
465

    
466

    
467
Improvements
468
~~~~~~~~~~~~
469

    
470
- Improved network configuration for the KVM hypervisor
471
- Added e1000 as a supported NIC for Xen-HVM
472
- Improved the lvmstrap tool to also be able to use partitions, as
473
  opposed to full disks
474
- Improved speed of disk wiping (the cluster parameter
475
  ``prealloc_wipe_disks``, so that it has a low impact on the total time
476
  of instance creations
477
- Added documentation for the OS parameters
478
- Changed ``gnt-instance deactivate-disks`` so that it can work if the
479
  hypervisor is not responding
480
- Added display of blacklisted and hidden OS information in
481
  ``gnt-cluster info``
482
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
483
  NIC and node parameters, which might create problems with currently
484
  invalid (but undetected) configuration files, but prevents validation
485
  failures when unrelated parameters are modified
486
- Changed cluster initialisation to wait for the master daemon to become
487
  available
488
- Expanded the RAPI interface:
489

    
490
  - Added config redistribution resource
491
  - Added activation/deactivation of instance disks
492
  - Added export of console information
493

    
494
- Implemented log file reopening on SIGHUP, which allows using
495
  logrotate(8) for the Ganeti log files
496
- Added a basic OOB helper script as an example
497

504
User-visible
505
~~~~~~~~~~~~
506

    
507
- Fixed timezone issues when formatting timestamps
508
- Added support for node groups, available via ``gnt-group`` and other
509
  commands
510
- Added out-of-band framework and management, see :doc:`design
511
  document <design-oob>`
512
- Removed support for roman numbers from ``gnt-node list`` and
513
  ``gnt-instance list``.
514
- Allowed modification of master network interface via ``gnt-cluster
515
  modify --master-netdev``
516
- Accept offline secondaries while shutting down instance disks
517
- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors
518
- Added support for multiple LVM volume groups
519
- Avoid sorting nodes for ``gnt-node list`` if specific nodes are
520
  requested
521
- Added commands to list available fields:
522

    
523
  - ``gnt-node list-fields``
524
  - ``gnt-group list-fields``
525
  - ``gnt-instance list-fields``
526

    
527
- Updated documentation and man pages
528

    
529
Integration
530
~~~~~~~~~~~
531

    
532
- Moved ``rapi_users`` file into separate directory, now named
533
  ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
534
  symlink
535
- Added new tool for running commands on many machines,
536
  ``tools/ganeti-listrunner``
537
- Implemented more verbose result in ``OpInstanceConsole`` opcode, also
538
  improving the ``gnt-instance console`` output
539
- Allowed customisation of disk index separator at ``configure`` time
540
- Export node group allocation policy to :doc:`iallocator <iallocator>`
541
- Added support for non-partitioned md disks in ``lvmstrap``
542
- Added script to gracefully power off KVM instances
543
- Split ``utils`` module into smaller parts
544
- Changed query operations to return more detailed information, e.g.
545
  whether an information is unavailable due to an offline node. To use
546
  this new functionality, the LUXI call ``Query`` must be used. Field
547
  information is now stored by the master daemon and can be retrieved
548
  using ``QueryFields``. Instances, nodes and groups can also be queried
549
  using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
550
  exposed via RAPI). The following commands make use of this
551
  infrastructure change:
552

    
553
  - ``gnt-group list``
554
  - ``gnt-group list-fields``
555
  - ``gnt-node list``
556
  - ``gnt-node list-fields``
557
  - ``gnt-instance list``
558
  - ``gnt-instance list-fields``
559
  - ``gnt-debug locks``
560

    
561
Remote API
562
~~~~~~~~~~
563

    
564

565

    
566
  - ``/2/modify``
567
  - ``/2/groups``
568
  - ``/2/groups/[group_name]``
569
  - ``/2/groups/[group_name]/assign-nodes``
570
  - ``/2/groups/[group_name]/modify``
571
  - ``/2/groups/[group_name]/rename``
572
  - ``/2/instances/[instance_name]/disk/[disk_index]/grow``
573

    
574
- RAPI changes:
575

    
576
  - Implemented ``no_install`` for instance creation
577
  - Implemented OS parameters for instance reinstallation, allowing
578
    use of special settings on reinstallation (e.g. for preserving data)
579

776

    
777
Version 2.2.0 rc0
778
-----------------
779

    
780
*(Released Fri, 30 Jul 2010)*
781

    
782
Important change: the internal RPC mechanism between Ganeti nodes has
783
changed from using a home-grown http library (based on the Python base
784
libraries) to use the PycURL library. This requires that PycURL is
785
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
786
against GnuTLS by default. cURL's support for GnuTLS had known issues
787
before cURL 7.21.0 and we recommend using the latest cURL release or
788
linking against OpenSSL. Most other distributions already link PycURL
789
and cURL against OpenSSL. The command::
790

    
791
  python -c 'import pycurl; print pycurl.version'
792

    
793
can be used to determine the libraries PycURL and cURL are linked
794
against.
795

    
796
Other significant changes:
797

    
798
- Rewrote much of the internals of the job queue, in order to achieve
799
  better parallelism; this decouples job query operations from the job
800
  processing, and it should allow much nicer behaviour of the master
801
  daemon under load, and it also has uncovered some long-standing bugs
802
  related to the job serialisation (now fixed)
803
- Added a default iallocator setting to the cluster parameters,
804
  eliminating the need to always pass nodes or an iallocator for
805
  operations that require selection of new node(s)
806
- Added experimental support for the LXC virtualization method
807
- Added support for OS parameters, which allows the installation of
808
  instances to pass parameter to OS scripts in order to customise the
809
  instance
810
- Added a hypervisor parameter controlling the migration type (live or
811
  non-live), since hypervisors have various levels of reliability; this
812
  has renamed the 'live' parameter to 'mode'
813
- Added a cluster parameter ``reserved_lvs`` that denotes reserved
814
  logical volumes, meaning that cluster verify will ignore them and not
815
  flag their presence as errors
816
- The watcher will now reset the error count for failed instances after
817
  8 hours, thus allowing self-healing if the problem that caused the
818
  instances to be down/fail to start has cleared in the meantime
819
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
820
  check for, and warn, if the drbd module parameter ``usermode_helper``
821
  is not consistent with the cluster-wide setting; this is needed to
822
  make diagnose easier of failed drbd creations
823
- Started adding base IPv6 support, but this is not yet
824
  enabled/available for use
825
- Rename operations (cluster, instance) will now return the new name,
826
  which is especially useful if a short name was passed in
827
- Added support for instance migration in RAPI
828
- Added a tool to pre-configure nodes for the SSH setup, before joining
829
  them to the cluster; this will allow in the future a simplified model
830
  for node joining (but not yet fully enabled in 2.2); this needs the
831
  paramiko python library
832
- Fixed handling of name-resolving errors
833
- Fixed consistency of job results on the error path
834
- Fixed master-failover race condition when executed multiple times in
835
  sequence
836
- Fixed many bugs related to the job queue (mostly introduced during the
837
  2.2 development cycle, so not all are impacting 2.1)
838
- Fixed instance migration with missing disk symlinks
839
- Fixed handling of unknown jobs in ``gnt-job archive``
840
- And many other small fixes/improvements
841

    
842
Internal changes:
843

    
844
- Enhanced both the unittest and the QA coverage
845
- Switched the opcode validation to a generic model, and extended the
846
  validation to all opcode parameters
847
- Changed more parts of the code that write shell scripts to use the
848
  same class for this
849
- Switched the master daemon to use the asyncore library for the Luxi
850
  server endpoint
851

    
852

    
853
Version 2.2.0 beta 0
854
--------------------
855

    
856
*(Released Thu, 17 Jun 2010)*
857

    
858
- Added tool (``move-instance``) and infrastructure to move instances
859
  between separate clusters (see :doc:`separate documentation
860
  <move-instance>` and :doc:`design document <design-2.2>`)
861
- Added per-request RPC timeout
862
- RAPI now requires a Content-Type header for requests with a body (e.g.
863
  ``PUT`` or ``POST``) which must be set to ``application/json`` (see
864
  :rfc:`2616` (HTTP/1.1), section 7.2.1)
865
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
866
  reachable
867
- Implemented initial support for running Ganeti daemons as separate
868
  users, see configure-time flags ``--with-user-prefix`` and
869
  ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
870
  time)
871
- Instances can be removed after export (``gnt-backup export
872
  --remove-instance``)
873
- Self-signed certificates generated by Ganeti now use a 2048 bit RSA
874
  key (instead of 1024 bit)
875
- Added new cluster configuration file for cluster domain secret
876
- Import/export now use SSL instead of SSH
877
- Added support for showing estimated time when exporting an instance,
878
  see the ``ganeti-os-interface(7)`` manpage and look for
879
  ``EXP_SIZE_FD``
880

    
881

    
882
Version 2.1.8
883
-------------
884

    
885
*(Released Tue, 16 Nov 2010)*
886

    
887
Some more bugfixes. Unless critical bugs occur, this will be the last
888
2.1 release:
889

    
890
- Fix case of MAC special-values
891
- Fix mac checker regex
892
- backend: Fix typo causing "out of range" error
893
- Add missing --units in gnt-instance list man page
894

    
895

    
896
Version 2.1.7
897
-------------
898

    
899
*(Released Tue, 24 Aug 2010)*
900

    
901
Bugfixes only:
902
  - Don't ignore secondary node silently on non-mirrored disk templates
903
    (issue 113)
904
  - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
905
  - Fix usb_mouse parameter breaking with vnc_console (issue 109)
906
  - Properly document the usb_mouse parameter
907

909
    missing
910

913
Version 2.1.6
914
-------------
915

    
916
*(Released Fri, 16 Jul 2010)*
917

    
918
Bugfixes only:
919
  - Add an option to only select some reboot types during qa/burnin.
920
    (on some hypervisors consequent reboots are not supported)
921
  - Fix infrequent race condition in master failover. Sometimes the old
922
    master ip address would be still detected as up for a short time
923
    after it was removed, causing failover to fail.
924
  - Decrease mlockall warnings when the ctypes module is missing. On
925
    Python 2.4 we support running even if no ctypes module is installed,
926
    but we were too verbose about this issue.
927
  - Fix building on old distributions, on which man doesn't have a
928
    --warnings option.
929
  - Fix RAPI not to ignore the MAC address on instance creation
930
  - Implement the old instance creation format in the RAPI client.

Version 2.1.5
934
-------------
935

    
936
*(Released Thu, 01 Jul 2010)*

938
A small bugfix release:
939
  - Fix disk adoption: broken by strict --disk option checking in 2.1.4
940
  - Fix batch-create: broken in the whole 2.1 series due to a lookup on
941
    a non-existing option
942
  - Fix instance create: the --force-variant option was ignored
943
  - Improve pylint 0.21 compatibility and warnings with Python 2.6
944

Version 2.1.4
952
-------------
953

    
954
*(Released Fri, 18 Jun 2010)*
955

    
956
A small bugfix release:
957

    
958
  - Fix live migration of KVM instances started with older Ganeti
959
    versions which had fewer hypervisor parameters
960
  - Fix gnt-instance grow-disk on down instances
961
  - Fix an error-reporting bug during instance migration
962
  - Better checking of the ``--net`` and ``--disk`` values, to avoid
963
    silently ignoring broken ones
964
  - Fix an RPC error reporting bug affecting, for example, RAPI client
965
    users
966
  - Fix bug triggered by different API version os-es on different nodes
967
  - Fix a bug in instance startup with custom hvparams: OS level
968
    parameters would fail to be applied.
969
  - Fix the RAPI client under Python 2.6 (but more work is needed to
970
    make it work completely well with OpenSSL)
971
  - Fix handling of errors when resolving names from DNS
972

974
Version 2.1.3
975
-------------
976

    
977
*(Released Thu, 3 Jun 2010)*
978

    
979
A medium sized development cycle. Some new features, and some
980
fixes/small improvements/cleanups.
981

    
982
Significant features
983
~~~~~~~~~~~~~~~~~~~~
984

    
985
The node deamon now tries to mlock itself into memory, unless the
986
``--no-mlock`` flag is passed. It also doesn't fail if it can't write
987
its logs, and falls back to console logging. This allows emergency
988
features such as ``gnt-node powercycle`` to work even in the event of a
989
broken node disk (tested offlining the disk hosting the node's
990
filesystem and dropping its memory caches; don't try this at home)
991

    
992
KVM: add vhost-net acceleration support. It can be tested with a new
993
enough version of the kernel and of qemu-kvm.
994

    
995
KVM: Add instance chrooting feature. If you use privilege dropping for
996
your VMs you can also now force them to chroot to an empty directory,
997
before starting the emulated guest.
998

    
999
KVM: Add maximum migration bandwith and maximum downtime tweaking
1000
support (requires a new-enough version of qemu-kvm).
1001

    
1002
Cluster verify will now warn if the master node doesn't have the master
1003
ip configured on it.
1004

    
1005
Add a new (incompatible) instance creation request format to RAPI which
1006
supports all parameters (previously only a subset was supported, and it
1007
wasn't possible to extend the old format to accomodate all the new
1008
features. The old format is still supported, and a client can check for
1009
this feature, before using it, by checking for its presence in the
1010
``features`` RAPI resource.
1011

    
1012
Now with ancient latin support. Try it passing the ``--roman`` option to
1013
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
1014
(requires the python-roman module to be installed, in order to work).
1015

    
1016
Other changes
1017
~~~~~~~~~~~~~
1018

    
1019
As usual many internal code refactorings, documentation updates, and
1020
such. Among others:
1021

    
1022
  - Lots of improvements and cleanups to the experimental Remote API
1023
    (RAPI) client library.
1024
  - A new unit test suite for the core daemon libraries.
1025
  - A fix to creating missing directories makes sure the umask is not
1026
    applied anymore. This enforces the same directory permissions
1027
    everywhere.
1028
  - Better handling terminating daemons with ctrl+c (used when running
1029
    them in debugging mode).
1030
  - Fix a race condition in live migrating a KVM instance, when stat()
1031
    on the old proc status file returned EINVAL, which is an unexpected
1032
    value.
1033
  - Fixed manpage checking with newer man and utf-8 charachters. But now
1034
    you need the en_US.UTF-8 locale enabled to build Ganeti from git.
1035

    
1036

    
1037
Version 2.1.2.1
1038
---------------
1039

    
1040
*(Released Fri, 7 May 2010)*
1041

    
1042
Fix a bug which prevented untagged KVM instances from starting.
1043

    
1044

    
1045
Version 2.1.2
1046
-------------
1047

    
1048
*(Released Fri, 7 May 2010)*
1049

    
1050
Another release with a long development cycle, during which many
1051
different features were added.
1052

    
1053
Significant features
1054
~~~~~~~~~~~~~~~~~~~~
1055

    
1056
The KVM hypervisor now can run the individual instances as non-root, to
1057
reduce the impact of a VM being hijacked due to bugs in the
1058
hypervisor. It is possible to run all instances as a single (non-root)
1059
user, to manually specify a user for each instance, or to dynamically
1060
allocate a user out of a cluster-wide pool to each instance, with the
1061
guarantee that no two instances will run under the same user ID on any
1062
given node.
1063

    
1064
An experimental RAPI client library, that can be used standalone
1065
(without the other Ganeti libraries), is provided in the source tree as
1066
``lib/rapi/client.py``. Note this client might change its interface in
1067
the future, as we iterate on its capabilities.
1068

    
1069
A new command, ``gnt-cluster renew-crypto`` has been added to easily
1070
replace the cluster's certificates and crypto keys. This might help in
1071
case they have been compromised, or have simply expired.
1072

    
1073
A new disk option for instance creation has been added that allows one
1074
to "adopt" currently existing logical volumes, with data
1075
preservation. This should allow easier migration to Ganeti from
1076
unmanaged (or managed via other software) instances.
1077

    
1078
Another disk improvement is the possibility to convert between redundant
1079
(DRBD) and plain (LVM) disk configuration for an instance. This should
1080
allow better scalability (starting with one node and growing the
1081
cluster, or shrinking a two-node cluster to one node).
1082

    
1083
A new feature that could help with automated node failovers has been
1084
implemented: if a node sees itself as offline (by querying the master
1085
candidates), it will try to shutdown (hard) all instances and any active
1086
DRBD devices. This reduces the risk of duplicate instances if an
1087
external script automatically failovers the instances on such nodes. To
1088
enable this, the cluster parameter ``maintain_node_health`` should be
1089
enabled; in the future this option (per the name) will enable other
1090
automatic maintenance features.
1091

    
1092
Instance export/import now will reuse the original instance
1093
specifications for all parameters; that means exporting an instance,
1094
deleting it and the importing it back should give an almost identical
1095
instance. Note that the default import behaviour has changed from
1096
before, where it created only one NIC; now it recreates the original
1097
number of NICs.
1098

    
1099
Cluster verify has added a few new checks: SSL certificates validity,
1100
/etc/hosts consistency across the cluster, etc.
1101

    
1102
Other changes
1103
~~~~~~~~~~~~~
1104

    
1105
As usual, many internal changes were done, documentation fixes,
1106
etc. Among others:
1107

    
1108
- Fixed cluster initialization with disabled cluster storage (regression
1109
  introduced in 2.1.1)
1110
- File-based storage supports growing the disks
1111
- Fixed behaviour of node role changes
1112
- Fixed cluster verify for some corner cases, plus a general rewrite of
1113
  cluster verify to allow future extension with more checks
1114
- Fixed log spamming by watcher and node daemon (regression introduced
1115
  in 2.1.1)
1116
- Fixed possible validation issues when changing the list of enabled
1117
  hypervisors
1118
- Fixed cleanup of /etc/hosts during node removal
1119
- Fixed RAPI response for invalid methods
1120
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
1121
- Multiple small improvements to the KVM hypervisor (VNC usage, booting
1122
  from ide disks, etc.)
1123
- Allow OS changes without re-installation (to record a changed OS
1124
  outside of Ganeti, or to allow OS renames)
1125
- Allow instance creation without OS installation (useful for example if
1126
  the OS will be installed manually, or restored from a backup not in
1127
  Ganeti format)
1128
- Implemented option to make cluster ``copyfile`` use the replication
1129
  network
1130
- Added list of enabled hypervisors to ssconf (possibly useful for
1131
  external scripts)
1132
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
1133
  1.2 clusters
1134
- A partial form of node re-IP is possible via node readd, which now
1135
  allows changed node primary IP
1136
- Command line utilities now show an informational message if the job is
1137
  waiting for a lock
1138
- The logs of the master daemon now show the PID/UID/GID of the
1139
  connected client
1140

    
1141

    
1142
Version 2.1.1
1143
-------------
1144

    
1145
*(Released Fri, 12 Mar 2010)*
1146

    
1147
During the 2.1.0 long release candidate cycle, a lot of improvements and
1148
changes have accumulated with were released later as 2.1.1.
1149

    
1150
Major changes
1151
~~~~~~~~~~~~~
1152

    
1153
The node evacuate command (``gnt-node evacuate``) was significantly
1154
rewritten, and as such the IAllocator protocol was changed - a new
1155
request type has been added. This unfortunate change during a stable
1156
series is designed to improve performance of node evacuations; on
1157
clusters with more than about five nodes and which are well-balanced,
1158
evacuation should proceed in parallel for all instances of the node
1159
being evacuated. As such, any existing IAllocator scripts need to be
1160
updated, otherwise the above command will fail due to the unknown
1161
request. The provided "dumb" allocator has not been updated; but the
1162
ganeti-htools package supports the new protocol since version 0.2.4.
1163

    
1164
Another important change is increased validation of node and instance
1165
names. This might create problems in special cases, if invalid host
1166
names are being used.
1167

    
1168
Also, a new layer of hypervisor parameters has been added, that sits at
1169
OS level between the cluster defaults and the instance ones. This allows
1170
customisation of virtualization parameters depending on the installed
1171
OS. For example instances with OS 'X' may have a different KVM kernel
1172
(or any other parameter) than the cluster defaults. This is intended to
1173
help managing a multiple OSes on the same cluster, without manual
1174
modification of each instance's parameters.
1175

    
1176
A tool for merging clusters, ``cluster-merge``, has been added in the
1177
tools sub-directory.
1178

    
1179
Bug fixes
1180
~~~~~~~~~
1181

    
1182
- Improved the int/float conversions that should make the code more
1183
  robust in face of errors from the node daemons
1184
- Fixed the remove node code in case of internal configuration errors
1185
- Fixed the node daemon behaviour in face of inconsistent queue
1186
  directory (e.g. read-only file-system where we can't open the files
1187
  read-write, etc.)
1188
- Fixed the behaviour of gnt-node modify for master candidate demotion;
1189
  now it either aborts cleanly or, if given the new "auto_promote"
1190
  parameter, will automatically promote other nodes as needed
1191
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
1192
  completely prevent Ganeti from working
1193
- Fixed bug for instance export when not all disks were successfully
1194
  exported
1195
- Fixed behaviour of node add when the new node is slow in starting up
1196
  the node daemon
1197
- Fixed handling of signals in the LUXI client, which should improve
1198
  behaviour of command-line scripts
1199
- Added checks for invalid node/instance names in the configuration (now
1200
  flagged during cluster verify)
1201
- Fixed watcher behaviour for disk activation errors
1202
- Fixed two potentially endless loops in http library, which led to the
1203
  RAPI daemon hanging and consuming 100% CPU in some cases
1204
- Fixed bug in RAPI daemon related to hashed passwords
1205
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM
1206
  instances
1207
- Enhanced compatibility with non-Debian OSes, but not using absolute
1208
  path in some commands and allowing customisation of the ssh
1209
  configuration directory
1210
- Fixed possible future issue with new Python versions by abiding to the
1211
  proper use of ``__slots__`` attribute on classes
1212
- Added checks that should prevent directory traversal attacks
1213
- Many documentation fixes based on feedback from users
1214

    
1215
New features
1216
~~~~~~~~~~~~
1217

    
1218
- Added an "early_release" more for instance replace disks and node
1219
  evacuate, where we release locks earlier and thus allow higher
1220
  parallelism within the cluster
1221
- Added watcher hooks, intended to allow the watcher to restart other
1222
  daemons (e.g. from the ganeti-nbma project), but they can be used of
1223
  course for any other purpose
1224
- Added a compile-time disable for DRBD barriers, to increase
1225
  performance if the administrator trusts the power supply or the
1226
  storage system to not lose writes
1227
- Added the option of using syslog for logging instead of, or in
1228
  addition to, Ganeti's own log files
1229
- Removed boot restriction for paravirtual NICs for KVM, recent versions
1230
  can indeed boot from a paravirtual NIC
1231
- Added a generic debug level for many operations; while this is not
1232
  used widely yet, it allows one to pass the debug value all the way to
1233
  the OS scripts
1234
- Enhanced the hooks environment for instance moves (failovers,
1235
  migrations) where the primary/secondary nodes changed during the
1236
  operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
1237
- Enhanced data validations for many user-supplied values; one important
1238
  item is the restrictions imposed on instance and node names, which
1239
  might reject some (invalid) host names
1240
- Add a configure-time option to disable file-based storage, if it's not
1241
  needed; this allows greater security separation between the master
1242
  node and the other nodes from the point of view of the inter-node RPC
1243
  protocol
1244
- Added user notification in interactive tools if job is waiting in the
1245
  job queue or trying to acquire locks
1246
- Added log messages when a job is waiting for locks
1247
- Added filtering by node tags in instance operations which admit
1248
  multiple instances (start, stop, reboot, reinstall)
1249
- Added a new tool for cluster mergers, ``cluster-merge``
1250
- Parameters from command line which are of the form ``a=b,c=d`` can now
1251
  use backslash escapes to pass in values which contain commas,
1252
  e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
1253
  ``b,c``
1254
- For KVM, the instance name is the first parameter passed to KVM, so
1255
  that it's more visible in the process list
1256

    
1257

    
1258
Version 2.1.0
1259
-------------
1260

    
1261
*(Released Tue, 2 Mar 2010)*
1262

    
1263
Ganeti 2.1 brings many improvements with it. Major changes:
1264

    
1265
- Added infrastructure to ease automated disk repairs
1266
- Added new daemon to export configuration data in a cheaper way than
1267
  using the remote API
1268
- Instance NICs can now be routed instead of being associated with a
1269
  networking bridge
1270
- Improved job locking logic to reduce impact of jobs acquiring multiple
1271
  locks waiting for other long-running jobs
1272

    
1273
In-depth implementation details can be found in the Ganeti 2.1 design
1274
document.

  allows local and remote execution of arbitrary executables
1377
- Fix failure of gnt-node list during instance removal
1378
- Ship the RAPI documentation in the archive
1379

    
1380

    
1381
Version 2.0.4
1382
-------------
1383

    
1384
*(Released Wed, 30 Sep 2009)*
1385

    
1386
- Fixed many wrong messages
1387
- Fixed a few bugs related to the locking library
1388
- Fixed MAC checking at instance creation time
1389
- Fixed a DRBD parsing bug related to gaps in /proc/drbd
1390
- Fixed a few issues related to signal handling in both daemons and
1391
  scripts
1392
- Fixed the example startup script provided
1393
- Fixed insserv dependencies in the example startup script (patch from
1394
  Debian)
1395
- Fixed handling of drained nodes in the iallocator framework
1396
- Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1397
  #528618)
1398
- Fixed error related to invalid job IDs in job polling
1399
- Fixed job/opcode persistence on unclean master shutdown
1400
- Fixed handling of partial job processing after unclean master
1401
  shutdown
1402
- Fixed error reporting from LUs, previously all errors were converted
1403
  into execution errors
1404
- Fixed error reporting from burnin
1405
- Decreased significantly the memory usage of the job queue
1406
- Optimised slightly multi-job submission
1407
- Optimised slightly opcode loading
1408
- Backported the multi-job submit framework from the development
1409
  branch; multi-instance start and stop should be faster
1410
- Added script to clean archived jobs after 21 days; this will reduce
1411
  the size of the queue directory
1412
- Added some extra checks in disk size tracking
1413
- Added an example ethers hook script
1414
- Added a cluster parameter that prevents Ganeti from modifying of
1415
  /etc/hosts
1416
- Added more node information to RAPI responses
1417

1422
  automatically
1423
- Converted instance reinstall to multi-instance model
1424

    
1425

    
1426
Version 2.0.3
1427
-------------
1428

    
1429
*(Released Fri, 7 Aug 2009)*
1430

    
1431
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1432
  to allow using the pre-2.0.2 behaviour in activation, if any existing
1433
  instances have mismatched disk sizes in the configuration
1434
- Added ``gnt-cluster repair-disk-sizes`` command to check and update
1435
  any configuration mismatches for disk sizes
1436
- Added ``gnt-master cluste-failover --no-voting`` to allow master
1437
  failover to work on two-node clusters
1438
- Fixed the ``--net`` option of ``gnt-backup import``, which was
1439
  unusable
1440
- Fixed detection of OS script errors in ``gnt-backup export``
1441
- Fixed exit code of ``gnt-backup export``
1442

    
1443

    
1444
Version 2.0.2
1445
-------------
1446

    
1447
*(Released Fri, 17 Jul 2009)*
1448

    
1449
- Added experimental support for stripped logical volumes; this should
1450
  enhance performance but comes with a higher complexity in the block
1451
  device handling; stripping is only enabled when passing
1452
  ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1453
  affected even in the non-stripped mode
1454
- Improved resiliency against transient failures at the end of DRBD
1455
  resyncs, and in general of DRBD resync checks
1456
- Fixed a couple of issues with exports and snapshot errors
1457
- Fixed a couple of issues in instance listing
1458
- Added display of the disk size in ``gnt-instance info``
1459
- Fixed checking for valid OSes in instance creation
1460
- Fixed handling of the "vcpus" parameter in instance listing and in
1461
  general of invalid parameters
1462
- Fixed http server library, and thus RAPI, to handle invalid
1463
  username/password combinations correctly; this means that now they
1464
  report unauthorized for queries too, not only for modifications,
1465
  allowing earlier detect of configuration problems
1466
- Added a new "role" node list field, equivalent to the master/master
1467
  candidate/drained/offline flags combinations
1468
- Fixed cluster modify and changes of candidate pool size
1469
- Fixed cluster verify error messages for wrong files on regular nodes
1470
- Fixed a couple of issues with node demotion from master candidate role
1471
- Fixed node readd issues
1472
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1473
- Added a new ``--no-voting`` option for masterfailover to fix failover
1474
  on two-nodes clusters when the former master node is unreachable
1475
- Added instance reinstall over RAPI
1476

    
1477

    
1478
Version 2.0.1
1479
-------------
1480

    
1481
*(Released Tue, 16 Jun 2009)*
1482

    
1483
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1484
  allow re-adding the start in single-user option (regression from 1.2)
1485
- the watcher writes the instance status to a file, to allow monitoring
1486
  to report the instance status (from the master) based on cached
1487
  results of the watcher's queries; while this can get stale if the
1488
  watcher is being locked due to other work on the cluster, this is
1489
  still an improvement
1490
- the watcher now also restarts the node daemon and the rapi daemon if
1491
  they died
1492
- fixed the watcher to handle full and drained queue cases
1493
- hooks export more instance data in the environment, which helps if
1494
  hook scripts need to take action based on the instance's properties
1495
  (no longer need to query back into ganeti)
1496
- instance failovers when the instance is stopped do not check for free
1497
  RAM, so that failing over a stopped instance is possible in low memory
1498
  situations
1499
- rapi uses queries for tags instead of jobs (for less job traffic), and
1500
  for cluster tags it won't talk to masterd at all but read them from
1501
  ssconf
1502
- a couple of error handling fixes in RAPI
1503
- drbd handling: improved the error handling of inconsistent disks after
1504
  resync to reduce the frequency of "there are some degraded disks for
1505
  this instance" messages
1506
- fixed a bug in live migration when DRBD doesn't want to reconnect (the
1507
  error handling path called a wrong function name)
1508

    
1509

    
1510
Version 2.0.0 final
1511
-------------------
1512

    
1513
*(Released Wed, 27 May 2009)*
1514

    
1515
- no changes from rc5
1516

    
1517

    
1518
Version 2.0 release candidate 5
1519
-------------------------------
1520

    
1521
*(Released Wed, 20 May 2009)*
1522

    
1523
- fix a couple of bugs (validation, argument checks)
1524
- fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1525
- some small improvements to RAPI and IAllocator
1526
- make watcher automatically start the master daemon if down
1527

    
1528

    
1529
Version 2.0 release candidate 4
1530
-------------------------------
1531

    
1532
*(Released Mon, 27 Apr 2009)*
1533

    
1534
- change the OS list to not require locks; this helps with big clusters
1535
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1536
  volume group is broken
1537
- ``gnt-instance info``, without any arguments, doesn't run for all
1538
  instances anymore; either pass ``--all`` or pass the desired
1539
  instances; this helps against mistakes on big clusters where listing
1540
  the information for all instances takes a long time
1541
- miscellaneous doc and man pages fixes
1542

    
1543

    
1544
Version 2.0 release candidate 3
1545
-------------------------------
1546

    
1547
*(Released Wed, 8 Apr 2009)*
1548

    
1549
- Change the internal locking model of some ``gnt-node`` commands, in
1550
  order to reduce contention (and blocking of master daemon) when
1551
  batching many creation/reinstall jobs
1552
- Fixes to Xen soft reboot
1553
- No longer build documentation at build time, instead distribute it in
1554
  the archive, in order to reduce the need for the whole docbook/rst
1555
  toolchains
1556

    
1557

    
1558
Version 2.0 release candidate 2
1559
-------------------------------
1560

    
1561
*(Released Fri, 27 Mar 2009)*
1562

    
1563
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1564
- Fix watcher startup sequence, improves the behaviour of busy clusters
1565
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1566
  replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1567
  bind address and other places
1568
- Some documentation fixes and updates
1569

    
1570

    
1571
Version 2.0 release candidate 1
1572
-------------------------------
1573

    
1574
*(Released Mon, 2 Mar 2009)*
1575

    
1576
- More documentation updates, now all docs should be more-or-less
1577
  up-to-date
1578
- A couple of small fixes (mixed hypervisor clusters, offline nodes,
1579
  etc.)
1580
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1581
  and KVM)
1582
- Fix an issue related to $libdir/run/ganeti and cluster creation
1583

    
1584

    
1585
Version 2.0 beta 2
1586
------------------
1587

    
1588
*(Released Thu, 19 Feb 2009)*
1589

    
1590
- Xen PVM and KVM have switched the default value for the instance root
1591
  disk to the first partition on the first drive, instead of the whole
1592
  drive; this means that the OS installation scripts must be changed
1593
  accordingly
1594
- Man pages have been updated
1595
- RAPI has been switched by default to HTTPS, and the exported functions
1596
  should all work correctly
1597
- RAPI v1 has been removed
1598
- Many improvements to the KVM hypervisor
1599
- Block device errors are now better reported
1600
- Many other bugfixes and small improvements
1601

    
1602

    
1603
Version 2.0 beta 1
1604
------------------
1605

    
1606
*(Released Mon, 26 Jan 2009)*
1607

    
1608
- Version 2 is a general rewrite of the code and therefore the
1609
  differences are too many to list, see the design document for 2.0 in
1610
  the ``doc/`` subdirectory for more details
1611
- In this beta version there is not yet a migration path from 1.2 (there
1612
  will be one in the final 2.0 release)
1613
- A few significant changes are:
1614

    
1615
  - all commands are executed by a daemon (``ganeti-masterd``) and the
1616
    various ``gnt-*`` commands are just front-ends to it
1617
  - all the commands are entered into, and executed from a job queue,
1618
    see the ``gnt-job(8)`` manpage
1619
  - the RAPI daemon supports read-write operations, secured by basic
1620
    HTTP authentication on top of HTTPS
1621
  - DRBD version 0.7 support has been removed, DRBD 8 is the only
1622
    supported version (when migrating from Ganeti 1.2 to 2.0, you need
1623
    to migrate to DRBD 8 first while still running Ganeti 1.2)
1624
  - DRBD devices are using statically allocated minor numbers, which
1625
    will be assigned to existing instances during the migration process
1626
  - there is support for both Xen PVM and Xen HVM instances running on
1627
    the same cluster
1628
  - KVM virtualization is supported too
1629
  - file-based storage has been implemented, which means that it is
1630
    possible to run the cluster without LVM and DRBD storage, for
1631
    example using a shared filesystem exported from shared storage (and
1632
    still have live migration)
1633

    
1634

    
1635
Version 1.2.7
1636
-------------
1637

    
1638
*(Released Tue, 13 Jan 2009)*
1639

    
1640
- Change the default reboot type in ``gnt-instance reboot`` to "hard"
1641
- Reuse the old instance mac address by default on instance import, if
1642
  the instance name is the same.
1643
- Handle situations in which the node info rpc returns incomplete
1644
  results (issue 46)
1645
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1646
- Improved version of batcher:
1647

    
1648
  - state file support
1649
  - instance mac address support
1650
  - support for HVM clusters/instances
1651

    
1652
- Add an option to show the number of cpu sockets and nodes in
1653
  ``gnt-node list``
1654
- Support OSes that handle more than one version of the OS api (but do
1655
  not change the current API in any other way)
1656
- Fix ``gnt-node migrate``
1657
- ``gnt-debug`` man page
1658
- Fixes various more typos and small issues
1659
- Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1660

    
1661

    
1662
Version 1.2.6
1663
-------------
1664

    
1665
*(Released Wed, 24 Sep 2008)*
1666

    
1667
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1668
  type of disk exported to fully virtualized instances.
1669
- provide access to the serial console of HVM instances
1670
- instance auto_balance flag, set by default. If turned off it will
1671
  avoid warnings on cluster verify if there is not enough memory to fail
1672
  over an instance. in the future it will prevent automatically failing
1673
  it over when we will support that.
1674
- batcher tool for instance creation, see ``tools/README.batcher``
1675
- ``gnt-instance reinstall --select-os`` to interactively select a new
1676
  operating system when reinstalling an instance.
1677
- when changing the memory amount on instance modify a check has been
1678
  added that the instance will be able to start. also warnings are
1679
  emitted if the instance will not be able to fail over, if auto_balance
1680
  is true.
1681
- documentation fixes
1682
- sync fields between ``gnt-instance list/modify/add/import``
1683
- fix a race condition in drbd when the sync speed was set after giving
1684
  the device a remote peer.
1685

    
1686

    
1687
Version 1.2.5
1688
-------------
1689

    
1690
*(Released Tue, 22 Jul 2008)*
1691

    
1692
- note: the allowed size and number of tags per object were reduced
1693
- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1694
- fixed twisted 8.x compatibility
1695
- fixed ``gnt-instance replace-disks`` with iallocator
1696
- add TCP keepalives on twisted connections to detect restarted nodes
1697
- disk increase support, see ``gnt-instance grow-disk``
1698
- implement bulk node/instance query for RAPI
1699
- add tags in node/instance listing (optional)
1700
- experimental migration (and live migration) support, read the man page
1701
  for ``gnt-instance migrate``
1702
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1703
  has some small improvements in handling its state file
1704

    
1705

    
1706
Version 1.2.4
1707
-------------
1708

    
1709
*(Released Fri, 13 Jun 2008)*
1710

    
1711
- Experimental readonly, REST-based remote API implementation;
1712
  automatically started on master node, TCP port 5080, if enabled by
1713
  ``--enable-rapi`` parameter to configure script.
1714
- Instance allocator support. Add and import instance accept a
1715
  ``--iallocator`` parameter, and call that instance allocator to decide
1716
  which node to use for the instance. The iallocator document describes
1717
  what's expected from an allocator script.
1718
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1719
  ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1720
  node is lost there is still enough memory to fail over the instances
1721
  that reside on it.
1722
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1723
  ``gnt-cluster verify``, to check for site-specific compliance. All the
1724
  hooks will run, and their output, if any, will be displayed. Any
1725
  failing hook will make the verification return an error value.
1726
- ``gnt-cluster verify`` now checks that its peers are reachable on the
1727
  primary and secondary interfaces
1728
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1729
  that is still declared as part of the cluster and has failed.
1730
- ``gnt-* list`` commands now accept a new ``-o +field`` way of
1731
  specifying output fields, that just adds the chosen fields to the
1732
  default ones.
1733
- ``gnt-backup`` now has a new ``remove`` command to delete an existing
1734
  export from the filesystem.
1735
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1736
  have been added. Using them you can enable/disable acpi and pae
1737
  support, and specify a path for a cd image to be exported to the
1738
  instance. These parameters as the name suggest only work on HVM
1739
  clusters.
1740
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1741
  PAE support will be set to the previously hardcoded values, but the
1742
  (previously hardcoded) path to the CDROM ISO image will be unset and
1743
  if required, needs to be set manually with ``gnt-instance modify``
1744
  after the upgrade.
1745
- The address to which an instance's VNC console is bound is now
1746
  selectable per-instance, rather than being cluster wide. Of course
1747
  this only applies to instances controlled via VNC, so currently just
1748
  applies to HVM clusters.
1749

    
1750

    
1751
Version 1.2.3
1752
-------------
1753

    
1754
*(Released Mon, 18 Feb 2008)*
1755

    
1756
- more tweaks to the disk activation code (especially helpful for DRBD)
1757
- change the default ``gnt-instance list`` output format, now there is
1758
  one combined status field (see the manpage for the exact values this
1759
  field will have)
1760
- some more fixes for the mac export to hooks change
1761
- make Ganeti not break with DRBD 8.2.x (which changed the version
1762
  format in ``/proc/drbd``) (issue 24)
1763
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1764
  template, allowing migration from DRBD0.7+MD to DRBD8
1765

    
1766

    
1767
Version 1.2.2
1768
-------------
1769

*(Released Wed, 30 Jan 2008)*
1771

    
1772
- fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1773
  support (issue 23)
1774
- add command aliases infrastructure and a few aliases
1775
- allow listing of VCPUs in the ``gnt-instance list`` and improve the
1776
  man pages and the ``--help`` option of ``gnt-node
1777
  list``/``gnt-instance list``
1778
- fix ``gnt-backup list`` with down nodes (issue 21)
1779
- change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1780
- fix the dist archive and add a check for including svn/git files in
1781
  the future
1782
- some developer-related changes: improve the burnin and the QA suite,
1783
  add an upload script for testing during development
1784

    
1785

    
1786
Version 1.2.1
1787

1788

    
1789
*(Released Wed, 16 Jan 2008)*
1790

    
1791
- experimental HVM support, read the install document, section
1792
  "Initializing the cluster"
1793
- allow for the PVM hypervisor per-instance kernel and initrd paths
1794
- add a new command ``gnt-cluster verify-disks`` which uses a new
1795
  algorithm to improve the reconnection of the DRBD pairs if the device
1796
  on the secondary node has gone away
1797
- make logical volume code auto-activate LVs at disk activation time
1798
- slightly improve the speed of activating disks
1799
- allow specification of the MAC address at instance creation time, and
1800
  changing it later via ``gnt-instance modify``
1801
- fix handling of external commands that generate lots of output on
1802
  stderr
1803

- Change configuration file format from Python's Pickle to JSON.
1835
  Upgrading is possible using the cfgupgrade utility.
1836
- Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1837
  faster replace disks and is more stable (DRBD 8 has many improvements
1838
  compared to DRBD 0.7)
1839
- Added command line tags support (see man pages for ``gnt-instance``,
1840
  ``gnt-node``, ``gnt-cluster``)
1841
- Added instance rename support
1842
- Added multi-instance startup/shutdown
1843
- Added cluster rename support
1844
- Added ``gnt-node evacuate`` to simplify some node operations
1845
- Added instance reboot operation that can speedup reboot as compared to
1846
  stop and start
1847
- Soften the requirement that hostnames are in FQDN format
1848
- The ``ganeti-watcher`` now activates drbd pairs after secondary node
1849
  reboots
1850
- Removed dependency on debian's patched fping that uses the
1851
  non-standard ``-S`` option
1852
- Now the OS definitions are searched for in multiple, configurable
1853
  paths (easier for distros to package)
1854
- Some changes to the hooks infrastructure (especially the new
1855
  post-configuration update hook)
1856
- Other small bugfixes
