Version 2.5.0 beta1
5
-------------------
6

    
7
*(unreleased)*
8

    
9
- The default of the ``/2/instances/[instance_name]/rename`` RAPI
10
  resource's ``ip_check`` parameter changed from ``True`` to ``False``
11
  to match the underlying LUXI interface
12
- When creating file-based instances via RAPI, the ``file_driver``
13
  parameter no longer defaults to ``loop`` and must be specified
14
- The deprecated "bridge" nic parameter is no longer supported. Use
15
  "link" instead.
16
- Support for the undocumented and deprecated RAPI instance creation
17
  request format version 0 has been dropped. Use version 1, supported
18
  since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
19
- Pyparsing 1.4.6 or above is required, see :doc:`installation
20
  documentation <install>`

23
Version 2.4.1
24
-------------
25

    
26
*(Released Wed, 09 Mar 2011)*
27

    
28
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
29
the RAPI users file if run twice (even with ``-dry-run``).
30

    
31
The release fixes that bug (nothing else changed).
32

    
33

    
34
Version 2.4.0
35
-------------
36

    
37
*(Released Mon, 07 Mar 2011)*
38

    
39
Final 2.4.0 release. Just a few small fixes:
40

    
41
- Fixed RAPI node evacuate
42
- Fixed the kvm-ifup script
43
- Fixed internal error handling for special job cases
44
- Updated man page to specify the escaping feature for options
45

    
46

    
47
Version 2.4.0 rc3
48
-----------------
49

    
50
*(Released Mon, 28 Feb 2011)*
51

    
52
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
53
that this feature wiped the disks of the wrong instance, leading to loss
54
of data.
55

    
56
Other changes:
57

    
58
- Fixed title of query field containing instance name
59
- Expanded the glossary in the documentation
60
- Fixed one unittest (internal issue)
61

    
62

    
63
Version 2.4.0 rc2
64
-----------------
65

    
66
*(Released Mon, 21 Feb 2011)*
67

    
68
A number of bug fixes plus just a couple functionality changes.
69

    
70
On the user-visible side, the ``gnt-* list`` command output has changed
71
with respect to "special" field states. The current rc1 style of display
72
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
73
the default output mode special fields states are displayed as follows:
74

    
75
- Offline resource: ``*``
76
- Unavailable/not applicable: ``-``
77
- Data missing (RPC failure): ``?``
78
- Unknown field: ``??``
79

    
80
Another user-visible change is the addition of ``--force-join`` to
81
``gnt-node add``.
82

    
83
As for bug fixes:
84

    
85
- ``tools/cluster-merge`` has seen many fixes and is now enabled again
86
- Fixed regression in RAPI/instance reinstall where all parameters were
87
  required (instead of optional)
88
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
89
- Fixed iallocator usage (offline nodes were not considered offline)
90
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes
91
- Fixed hypervisor and OS parameter validation with respect to
92
  non-vm_capable nodes
93
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
94
  cosmetic)
95
- Fixed ``tools/listrunner`` with respect to agent-based usage
96

    
97

    
98
Version 2.4.0 rc1
99
-----------------
100

    
101
*(Released Fri,  4 Feb 2011)*
102

    
103
Many changes and fixes since the beta1 release. While there were some
104
internal changes, the code has been mostly stabilised for the RC
105
release.
106

    
107
Note: the dumb allocator was removed in this release, as it was not kept
108
up-to-date with the IAllocator protocol changes. It is recommended to
109
use the ``hail`` command from the ganeti-htools package.
110

    
111
Note: the 2.4 and up versions of Ganeti are not compatible with the
112
0.2.x branch of ganeti-htools. You need to upgrade to
113
ganeti-htools-0.3.0 (or later).
114

    
115
Regressions fixed from 2.3
116
~~~~~~~~~~~~~~~~~~~~~~~~~~
117

    
118
- Fixed the ``gnt-cluster verify-disks`` command
119
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to
120
  serially on nodes)
121
- Fixed disk adoption breakage
122
- Fixed wrong headers in instance listing for field aliases
123

    
124
Other bugs fixed
125
~~~~~~~~~~~~~~~~
126

    
127
- Fixed corner case in KVM handling of NICs
128
- Fixed many cases of wrong handling of non-vm_capable nodes
129
- Fixed a bug where a missing instance symlink was not possible to
130
  recreate with any ``gnt-*`` command (now ``gnt-instance
131
  activate-disks`` does it)
132
- Fixed the volume group name as reported by ``gnt-cluster
133
  verify-disks``
134
- Increased timeouts for the import-export code, hopefully leading to
135
  fewer aborts due network or instance timeouts
136
- Fixed bug in ``gnt-node list-storage``
137
- Fixed bug where not all daemons were started on cluster
138
  initialisation, but only at the first watcher run
139
- Fixed many bugs in the OOB implementation
140
- Fixed watcher behaviour in presence of instances with offline
141
  secondaries
142
- Fixed instance list output for instances running on the wrong node
143
- a few fixes to the cluster-merge tool, but it still cannot merge
144
  multi-node groups (currently it is not recommended to use this tool)
145

    
146

    
147
Improvements
148
~~~~~~~~~~~~
149

    
150
- Improved network configuration for the KVM hypervisor
151
- Added e1000 as a supported NIC for Xen-HVM
152
- Improved the lvmstrap tool to also be able to use partitions, as
153
  opposed to full disks
154
- Improved speed of disk wiping (the cluster parameter
155
  ``prealloc_wipe_disks``, so that it has a low impact on the total time
156
  of instance creations
157
- Added documentation for the OS parameters
158
- Changed ``gnt-instance deactivate-disks`` so that it can work if the
159
  hypervisor is not responding
160
- Added display of blacklisted and hidden OS information in
161
  ``gnt-cluster info``
162
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
163
  NIC and node parameters, which might create problems with currently
164
  invalid (but undetected) configuration files, but prevents validation
165
  failures when unrelated parameters are modified
166
- Changed cluster initialisation to wait for the master daemon to become
167
  available
168
- Expanded the RAPI interface:
169

    
170
  - Added config redistribution resource
171
  - Added activation/deactivation of instance disks
172
  - Added export of console information
173

    
174
- Implemented log file reopening on SIGHUP, which allows using
175
  logrotate(8) for the Ganeti log files
176
- Added a basic OOB helper script as an example
177

    
178

    
179
Version 2.4.0 beta1
180
-------------------
181

    
182
*(Released Fri, 14 Jan 2011)*
183

    
184
User-visible
185
~~~~~~~~~~~~
186

    
187
- Fixed timezone issues when formatting timestamps
188
- Added support for node groups, available via ``gnt-group`` and other
189
  commands
190
- Added out-of-band framework and management, see :doc:`design
191
  document <design-oob>`
192
- Removed support for roman numbers from ``gnt-node list`` and
193
  ``gnt-instance list``.
194
- Allowed modification of master network interface via ``gnt-cluster
195
  modify --master-netdev``
196
- Accept offline secondaries while shutting down instance disks
197
- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors
198
- Added support for multiple LVM volume groups
199
- Avoid sorting nodes for ``gnt-node list`` if specific nodes are
200
  requested
201
- Added commands to list available fields:
202

    
203
  - ``gnt-node list-fields``
204
  - ``gnt-group list-fields``
205
  - ``gnt-instance list-fields``
206

    
207
- Updated documentation and man pages
208

    
209
Integration
210
~~~~~~~~~~~
211

    
212
- Moved ``rapi_users`` file into separate directory, now named
213
  ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
214
  symlink
215
- Added new tool for running commands on many machines,
216
  ``tools/ganeti-listrunner``
217
- Implemented more verbose result in ``OpInstanceConsole`` opcode, also
218
  improving the ``gnt-instance console`` output
219
- Allowed customisation of disk index separator at ``configure`` time
220
- Export node group allocation policy to :doc:`iallocator <iallocator>`
221
- Added support for non-partitioned md disks in ``lvmstrap``
222
- Added script to gracefully power off KVM instances
223
- Split ``utils`` module into smaller parts
224
- Changed query operations to return more detailed information, e.g.
225
  whether an information is unavailable due to an offline node. To use
226
  this new functionality, the LUXI call ``Query`` must be used. Field
227
  information is now stored by the master daemon and can be retrieved
228
  using ``QueryFields``. Instances, nodes and groups can also be queried
229
  using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
230
  exposed via RAPI). The following commands make use of this
231
  infrastructure change:
232

    
233
  - ``gnt-group list``
234
  - ``gnt-group list-fields``
235
  - ``gnt-node list``
236
  - ``gnt-node list-fields``
237
  - ``gnt-instance list``
238
  - ``gnt-instance list-fields``
239
  - ``gnt-debug locks``
240

    
241
Remote API
242
~~~~~~~~~~
243

    
244
- New RAPI resources (see :doc:`rapi`):
245

    
246
  - ``/2/modify``
247
  - ``/2/groups``
248
  - ``/2/groups/[group_name]``
249
  - ``/2/groups/[group_name]/assign-nodes``
250
  - ``/2/groups/[group_name]/modify``
251
  - ``/2/groups/[group_name]/rename``
252
  - ``/2/instances/[instance_name]/disk/[disk_index]/grow``
253

    
254
- RAPI changes:
255

    
256
  - Implemented ``no_install`` for instance creation
257
  - Implemented OS parameters for instance reinstallation, allowing
258
    use of special settings on reinstallation (e.g. for preserving data)
259

    
260
Misc
261

456

    
457
Version 2.2.0 rc0
458
-----------------
459

    
460
*(Released Fri, 30 Jul 2010)*
461

    
462
Important change: the internal RPC mechanism between Ganeti nodes has
463
changed from using a home-grown http library (based on the Python base
464
libraries) to use the PycURL library. This requires that PycURL is
465
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
466
against GnuTLS by default. cURL's support for GnuTLS had known issues
467
before cURL 7.21.0 and we recommend using the latest cURL release or
468
linking against OpenSSL. Most other distributions already link PycURL
469
and cURL against OpenSSL. The command::
470

    
471
  python -c 'import pycurl; print pycurl.version'
472

    
473
can be used to determine the libraries PycURL and cURL are linked
474
against.
475

    
476
Other significant changes:
477

    
478
- Rewrote much of the internals of the job queue, in order to achieve
479
  better parallelism; this decouples job query operations from the job
480
  processing, and it should allow much nicer behaviour of the master
481
  daemon under load, and it also has uncovered some long-standing bugs
482
  related to the job serialisation (now fixed)
483
- Added a default iallocator setting to the cluster parameters,
484
  eliminating the need to always pass nodes or an iallocator for
485
  operations that require selection of new node(s)
486
- Added experimental support for the LXC virtualization method
487
- Added support for OS parameters, which allows the installation of
488
  instances to pass parameter to OS scripts in order to customise the
489
  instance
490
- Added a hypervisor parameter controlling the migration type (live or
491
  non-live), since hypervisors have various levels of reliability; this
492
  has renamed the 'live' parameter to 'mode'
493
- Added a cluster parameter ``reserved_lvs`` that denotes reserved
494
  logical volumes, meaning that cluster verify will ignore them and not
495
  flag their presence as errors
496
- The watcher will now reset the error count for failed instances after
497
  8 hours, thus allowing self-healing if the problem that caused the
498
  instances to be down/fail to start has cleared in the meantime
499
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
500
  check for, and warn, if the drbd module parameter ``usermode_helper``
501
  is not consistent with the cluster-wide setting; this is needed to
502
  make diagnose easier of failed drbd creations
503
- Started adding base IPv6 support, but this is not yet
504
  enabled/available for use
505
- Rename operations (cluster, instance) will now return the new name,
506
  which is especially useful if a short name was passed in
507
- Added support for instance migration in RAPI
508
- Added a tool to pre-configure nodes for the SSH setup, before joining
509
  them to the cluster; this will allow in the future a simplified model
510
  for node joining (but not yet fully enabled in 2.2); this needs the
511
  paramiko python library
512
- Fixed handling of name-resolving errors
513
- Fixed consistency of job results on the error path
514
- Fixed master-failover race condition when executed multiple times in
515
  sequence
516
- Fixed many bugs related to the job queue (mostly introduced during the
517
  2.2 development cycle, so not all are impacting 2.1)
518
- Fixed instance migration with missing disk symlinks
519
- Fixed handling of unknown jobs in ``gnt-job archive``
520
- And many other small fixes/improvements
521

    
522
Internal changes:
523

    
524
- Enhanced both the unittest and the QA coverage
525
- Switched the opcode validation to a generic model, and extended the
526
  validation to all opcode parameters
527
- Changed more parts of the code that write shell scripts to use the
528
  same class for this
529
- Switched the master daemon to use the asyncore library for the Luxi
530
  server endpoint
531

533
Version 2.2.0 beta 0
534
--------------------
535

    
536
*(Released Thu, 17 Jun 2010)*
537

    
538
- Added tool (``move-instance``) and infrastructure to move instances
539
  between separate clusters (see :doc:`separate documentation
540
  <move-instance>` and :doc:`design document <design-2.2>`)
541
- Added per-request RPC timeout
542
- RAPI now requires a Content-Type header for requests with a body (e.g.
543
  ``PUT`` or ``POST``) which must be set to ``application/json`` (see
544
  :rfc:`2616` (HTTP/1.1), section 7.2.1)
545
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
546
  reachable
547
- Implemented initial support for running Ganeti daemons as separate
548
  users, see configure-time flags ``--with-user-prefix`` and
549
  ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
550
  time)
551
- Instances can be removed after export (``gnt-backup export
552
  --remove-instance``)
553
- Self-signed certificates generated by Ganeti now use a 2048 bit RSA
554
  key (instead of 1024 bit)
555
- Added new cluster configuration file for cluster domain secret
556
- Import/export now use SSL instead of SSH
557
- Added support for showing estimated time when exporting an instance,
558
  see the ``ganeti-os-interface(7)`` manpage and look for
559
  ``EXP_SIZE_FD``
560

Version 2.1.8
563
-------------
564

    
565
*(Released Tue, 16 Nov 2010)*
566

    
567
Some more bugfixes. Unless critical bugs occur, this will be the last
568
2.1 release:
569

    
570
- Fix case of MAC special-values
571
- Fix mac checker regex
572
- backend: Fix typo causing "out of range" error
573
- Add missing --units in gnt-instance list man page
574

    
575

    
576
Version 2.1.7
577
-------------
578

    
579
*(Released Tue, 24 Aug 2010)*
580

    
581
Bugfixes only:
582
  - Don't ignore secondary node silently on non-mirrored disk templates
583
    (issue 113)
584
  - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
585
  - Fix usb_mouse parameter breaking with vnc_console (issue 109)
586
  - Properly document the usb_mouse parameter
587
  - Fix path in ganeti-rapi(8) (issue 116)
588
  - Adjust error message when the ganeti user's .ssh directory is
589
    missing
590
  - Add same-node-check when changing the disk template to drbd
591

    
592

    
593
Version 2.1.6
594
-------------
595

    
596
*(Released Fri, 16 Jul 2010)*
597

    
598
Bugfixes only:
599
  - Add an option to only select some reboot types during qa/burnin.
600
    (on some hypervisors consequent reboots are not supported)
601
  - Fix infrequent race condition in master failover. Sometimes the old
602
    master ip address would be still detected as up for a short time
603
    after it was removed, causing failover to fail.
604
  - Decrease mlockall warnings when the ctypes module is missing. On
605
    Python 2.4 we support running even if no ctypes module is installed,
606
    but we were too verbose about this issue.
607
  - Fix building on old distributions, on which man doesn't have a
608
    --warnings option.
609
  - Fix RAPI not to ignore the MAC address on instance creation
610
  - Implement the old instance creation format in the RAPI client.

614
-------------
615

    
616
*(Released Thu, 01 Jul 2010)*

618
A small bugfix release:
619
  - Fix disk adoption: broken by strict --disk option checking in 2.1.4
620
  - Fix batch-create: broken in the whole 2.1 series due to a lookup on
621
    a non-existing option
622
  - Fix instance create: the --force-variant option was ignored
623
  - Improve pylint 0.21 compatibility and warnings with Python 2.6
624
  - Fix modify node storage with non-FQDN arguments

  - Fix RAPI client to authenticate under Python 2.6 when used
626
    for more than 5 requests needing authentication
627
  - Fix gnt-instance modify -t (storage) giving a wrong error message
628
    when converting a non-shutdown drbd instance to plain
629

    
630

    
631

636
A small bugfix release:
637

    
638
  - Fix live migration of KVM instances started with older Ganeti
639
    versions which had fewer hypervisor parameters
640
  - Fix gnt-instance grow-disk on down instances
641
  - Fix an error-reporting bug during instance migration
642
  - Better checking of the ``--net`` and ``--disk`` values, to avoid
643
    silently ignoring broken ones
644
  - Fix an RPC error reporting bug affecting, for example, RAPI client
645
    users
646
  - Fix bug triggered by different API version os-es on different nodes
647
  - Fix a bug in instance startup with custom hvparams: OS level
648
    parameters would fail to be applied.
649
  - Fix the RAPI client under Python 2.6 (but more work is needed to
650
    make it work completely well with OpenSSL)
651
  - Fix handling of errors when resolving names from DNS
652

    
653

    
654
Version 2.1.3
655
-------------
656

    
657
*(Released Thu, 3 Jun 2010)*
658

    
659
A medium sized development cycle. Some new features, and some
660
fixes/small improvements/cleanups.
661

    
662
Significant features
663
~~~~~~~~~~~~~~~~~~~~
664

    
665
The node deamon now tries to mlock itself into memory, unless the
666
``--no-mlock`` flag is passed. It also doesn't fail if it can't write
667
its logs, and falls back to console logging. This allows emergency
668
features such as ``gnt-node powercycle`` to work even in the event of a
669
broken node disk (tested offlining the disk hosting the node's
670
filesystem and dropping its memory caches; don't try this at home)
671

    
672
KVM: add vhost-net acceleration support. It can be tested with a new
673
enough version of the kernel and of qemu-kvm.
674

    
675
KVM: Add instance chrooting feature. If you use privilege dropping for
676
your VMs you can also now force them to chroot to an empty directory,
677
before starting the emulated guest.
678

    
679
KVM: Add maximum migration bandwith and maximum downtime tweaking
680
support (requires a new-enough version of qemu-kvm).
681

    
682
Cluster verify will now warn if the master node doesn't have the master
683
ip configured on it.
684

    
685
Add a new (incompatible) instance creation request format to RAPI which
686
supports all parameters (previously only a subset was supported, and it
687
wasn't possible to extend the old format to accomodate all the new
688
features. The old format is still supported, and a client can check for
689
this feature, before using it, by checking for its presence in the
690
``features`` RAPI resource.
691

    
692
Now with ancient latin support. Try it passing the ``--roman`` option to
693
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
694
(requires the python-roman module to be installed, in order to work).
695

    
696
Other changes
697
~~~~~~~~~~~~~
698

    
699
As usual many internal code refactorings, documentation updates, and
700
such. Among others:
701

    
702
  - Lots of improvements and cleanups to the experimental Remote API
703
    (RAPI) client library.
704
  - A new unit test suite for the core daemon libraries.
705
  - A fix to creating missing directories makes sure the umask is not
706
    applied anymore. This enforces the same directory permissions
707
    everywhere.
708
  - Better handling terminating daemons with ctrl+c (used when running
709
    them in debugging mode).
710
  - Fix a race condition in live migrating a KVM instance, when stat()
711
    on the old proc status file returned EINVAL, which is an unexpected
712
    value.
713
  - Fixed manpage checking with newer man and utf-8 charachters. But now
714
    you need the en_US.UTF-8 locale enabled to build Ganeti from git.
715

    
716

    
717
Version 2.1.2.1
718
---------------
719

    
720
*(Released Fri, 7 May 2010)*
721

    
722
Fix a bug which prevented untagged KVM instances from starting.
723

    
724

    
725
Version 2.1.2
726
-------------
727

    
728
*(Released Fri, 7 May 2010)*
729

    
730
Another release with a long development cycle, during which many
731
different features were added.
732

    
733
Significant features
734
~~~~~~~~~~~~~~~~~~~~
735

    
736
The KVM hypervisor now can run the individual instances as non-root, to
737
reduce the impact of a VM being hijacked due to bugs in the
738
hypervisor. It is possible to run all instances as a single (non-root)
739
user, to manually specify a user for each instance, or to dynamically
740
allocate a user out of a cluster-wide pool to each instance, with the
741
guarantee that no two instances will run under the same user ID on any
742
given node.
743

    
744
An experimental RAPI client library, that can be used standalone
745
(without the other Ganeti libraries), is provided in the source tree as
746
``lib/rapi/client.py``. Note this client might change its interface in
747
the future, as we iterate on its capabilities.
748

    
749
A new command, ``gnt-cluster renew-crypto`` has been added to easily
750
replace the cluster's certificates and crypto keys. This might help in
751
case they have been compromised, or have simply expired.
752

    
753
A new disk option for instance creation has been added that allows one
754
to "adopt" currently existing logical volumes, with data
755
preservation. This should allow easier migration to Ganeti from
756
unmanaged (or managed via other software) instances.
757

    
758
Another disk improvement is the possibility to convert between redundant
759
(DRBD) and plain (LVM) disk configuration for an instance. This should
760
allow better scalability (starting with one node and growing the
761
cluster, or shrinking a two-node cluster to one node).
762

    
763
A new feature that could help with automated node failovers has been
764
implemented: if a node sees itself as offline (by querying the master
765
candidates), it will try to shutdown (hard) all instances and any active
766
DRBD devices. This reduces the risk of duplicate instances if an
767
external script automatically failovers the instances on such nodes. To
768
enable this, the cluster parameter ``maintain_node_health`` should be
769
enabled; in the future this option (per the name) will enable other
770
automatic maintenance features.
771

    
772
Instance export/import now will reuse the original instance
773
specifications for all parameters; that means exporting an instance,
774
deleting it and the importing it back should give an almost identical
775
instance. Note that the default import behaviour has changed from
776
before, where it created only one NIC; now it recreates the original
777
number of NICs.
778

    
779
Cluster verify has added a few new checks: SSL certificates validity,
780
/etc/hosts consistency across the cluster, etc.
781

    
782
Other changes
783
~~~~~~~~~~~~~
784

    
785
As usual, many internal changes were done, documentation fixes,
786
etc. Among others:
787

    
788
- Fixed cluster initialization with disabled cluster storage (regression
789
  introduced in 2.1.1)
790
- File-based storage supports growing the disks
791
- Fixed behaviour of node role changes
792
- Fixed cluster verify for some corner cases, plus a general rewrite of
793
  cluster verify to allow future extension with more checks
794
- Fixed log spamming by watcher and node daemon (regression introduced
795
  in 2.1.1)
796
- Fixed possible validation issues when changing the list of enabled
797
  hypervisors
798
- Fixed cleanup of /etc/hosts during node removal
799
- Fixed RAPI response for invalid methods
800
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
801
- Multiple small improvements to the KVM hypervisor (VNC usage, booting
802
  from ide disks, etc.)
803
- Allow OS changes without re-installation (to record a changed OS
804
  outside of Ganeti, or to allow OS renames)
805
- Allow instance creation without OS installation (useful for example if
806
  the OS will be installed manually, or restored from a backup not in
807
  Ganeti format)
808
- Implemented option to make cluster ``copyfile`` use the replication
809
  network
810
- Added list of enabled hypervisors to ssconf (possibly useful for
811
  external scripts)
812
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
813
  1.2 clusters
814
- A partial form of node re-IP is possible via node readd, which now
815
  allows changed node primary IP
816
- Command line utilities now show an informational message if the job is
817
  waiting for a lock
818
- The logs of the master daemon now show the PID/UID/GID of the
819
  connected client
820

    
821

    
822
Version 2.1.1
823
-------------
824

    
825
*(Released Fri, 12 Mar 2010)*
826

    
827
During the 2.1.0 long release candidate cycle, a lot of improvements and
828
changes have accumulated with were released later as 2.1.1.
829

    
830
Major changes
831
~~~~~~~~~~~~~
832

    
833
The node evacuate command (``gnt-node evacuate``) was significantly
834
rewritten, and as such the IAllocator protocol was changed - a new
835
request type has been added. This unfortunate change during a stable
836
series is designed to improve performance of node evacuations; on
837
clusters with more than about five nodes and which are well-balanced,
838
evacuation should proceed in parallel for all instances of the node
839
being evacuated. As such, any existing IAllocator scripts need to be
840
updated, otherwise the above command will fail due to the unknown
841
request. The provided "dumb" allocator has not been updated; but the
842
ganeti-htools package supports the new protocol since version 0.2.4.
843

    
844
Another important change is increased validation of node and instance
845
names. This might create problems in special cases, if invalid host
846
names are being used.
847

    
848
Also, a new layer of hypervisor parameters has been added, that sits at
849
OS level between the cluster defaults and the instance ones. This allows
850
customisation of virtualization parameters depending on the installed
851
OS. For example instances with OS 'X' may have a different KVM kernel
852
(or any other parameter) than the cluster defaults. This is intended to
853
help managing a multiple OSes on the same cluster, without manual
854
modification of each instance's parameters.
855

    
856
A tool for merging clusters, ``cluster-merge``, has been added in the
857
tools sub-directory.
858

    
859
Bug fixes
860
~~~~~~~~~
861

    
862
- Improved the int/float conversions that should make the code more
863
  robust in face of errors from the node daemons
864
- Fixed the remove node code in case of internal configuration errors
865
- Fixed the node daemon behaviour in face of inconsistent queue
866
  directory (e.g. read-only file-system where we can't open the files
867
  read-write, etc.)
868
- Fixed the behaviour of gnt-node modify for master candidate demotion;
869
  now it either aborts cleanly or, if given the new "auto_promote"
870
  parameter, will automatically promote other nodes as needed
871
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
872
  completely prevent Ganeti from working
873
- Fixed bug for instance export when not all disks were successfully
874
  exported
875
- Fixed behaviour of node add when the new node is slow in starting up
876
  the node daemon
877
- Fixed handling of signals in the LUXI client, which should improve
878
  behaviour of command-line scripts
879
- Added checks for invalid node/instance names in the configuration (now
880
  flagged during cluster verify)
881
- Fixed watcher behaviour for disk activation errors
882
- Fixed two potentially endless loops in http library, which led to the
883
  RAPI daemon hanging and consuming 100% CPU in some cases
884
- Fixed bug in RAPI daemon related to hashed passwords
885
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM
886
  instances
887
- Enhanced compatibility with non-Debian OSes, but not using absolute
888
  path in some commands and allowing customisation of the ssh
889
  configuration directory
890
- Fixed possible future issue with new Python versions by abiding to the
891
  proper use of ``__slots__`` attribute on classes
892
- Added checks that should prevent directory traversal attacks
893
- Many documentation fixes based on feedback from users
894

    
895
New features
896
~~~~~~~~~~~~
897

    
898
- Added an "early_release" more for instance replace disks and node
899
  evacuate, where we release locks earlier and thus allow higher
900
  parallelism within the cluster
901
- Added watcher hooks, intended to allow the watcher to restart other
902
  daemons (e.g. from the ganeti-nbma project), but they can be used of
903
  course for any other purpose
904
- Added a compile-time disable for DRBD barriers, to increase
905
  performance if the administrator trusts the power supply or the
906
  storage system to not lose writes
907
- Added the option of using syslog for logging instead of, or in
908
  addition to, Ganeti's own log files
909
- Removed boot restriction for paravirtual NICs for KVM, recent versions
910
  can indeed boot from a paravirtual NIC
911
- Added a generic debug level for many operations; while this is not
912
  used widely yet, it allows one to pass the debug value all the way to
913
  the OS scripts
914
- Enhanced the hooks environment for instance moves (failovers,
915
  migrations) where the primary/secondary nodes changed during the
916
  operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
917
- Enhanced data validations for many user-supplied values; one important
918
  item is the restrictions imposed on instance and node names, which
919
  might reject some (invalid) host names
920
- Add a configure-time option to disable file-based storage, if it's not
921
  needed; this allows greater security separation between the master
922
  node and the other nodes from the point of view of the inter-node RPC
923
  protocol
924
- Added user notification in interactive tools if job is waiting in the
925
  job queue or trying to acquire locks
926
- Added log messages when a job is waiting for locks
927
- Added filtering by node tags in instance operations which admit
928
  multiple instances (start, stop, reboot, reinstall)
929
- Added a new tool for cluster mergers, ``cluster-merge``
930
- Parameters from command line which are of the form ``a=b,c=d`` can now
931
  use backslash escapes to pass in values which contain commas,
932
  e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
933
  ``b,c``
934
- For KVM, the instance name is the first parameter passed to KVM, so
935
  that it's more visible in the process list
936

    
937

    
938
Version 2.1.0
939
-------------
940

    
941
*(Released Tue, 2 Mar 2010)*
942

    
943
Ganeti 2.1 brings many improvements with it. Major changes:
944

    
945
- Added infrastructure to ease automated disk repairs
946
- Added new daemon to export configuration data in a cheaper way than
947
  using the remote API
948
- Instance NICs can now be routed instead of being associated with a
949
  networking bridge
950
- Improved job locking logic to reduce impact of jobs acquiring multiple
951
  locks waiting for other long-running jobs
952

    
953
In-depth implementation details can be found in the Ganeti 2.1 design
954
document.

Version 2.0.4
1062
-------------
1063

    
1064
*(Released Wed, 30 Sep 2009)*
1065

1076
- Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1077
  #528618)
1078
- Fixed error related to invalid job IDs in job polling
1079
- Fixed job/opcode persistence on unclean master shutdown
1080
- Fixed handling of partial job processing after unclean master
1081
  shutdown
1082
- Fixed error reporting from LUs, previously all errors were converted
1083
  into execution errors
1084
- Fixed error reporting from burnin
1085
- Decreased significantly the memory usage of the job queue
1086
- Optimised slightly multi-job submission
1087
- Optimised slightly opcode loading
1088
- Backported the multi-job submit framework from the development
1089
  branch; multi-instance start and stop should be faster
1090
- Added script to clean archived jobs after 21 days; this will reduce
1091
  the size of the queue directory
1092
- Added some extra checks in disk size tracking

1104

    
1105

    
1106
Version 2.0.3
1107
-------------
1108

    
1109
*(Released Fri, 7 Aug 2009)*
1110

    
1111
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1112
  to allow using the pre-2.0.2 behaviour in activation, if any existing
1113
  instances have mismatched disk sizes in the configuration
1114
- Added ``gnt-cluster repair-disk-sizes`` command to check and update
1115
  any configuration mismatches for disk sizes
1116
- Added ``gnt-master cluste-failover --no-voting`` to allow master
1117
  failover to work on two-node clusters
1118
- Fixed the ``--net`` option of ``gnt-backup import``, which was
1119
  unusable
1120
- Fixed detection of OS script errors in ``gnt-backup export``
1121
- Fixed exit code of ``gnt-backup export``
1122

    
1123

    
1124
Version 2.0.2
1125
-------------
1126

    
1127
*(Released Fri, 17 Jul 2009)*
1128

    
1129
- Added experimental support for stripped logical volumes; this should
1130
  enhance performance but comes with a higher complexity in the block
1131
  device handling; stripping is only enabled when passing
1132
  ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1133
  affected even in the non-stripped mode
1134
- Improved resiliency against transient failures at the end of DRBD
1135
  resyncs, and in general of DRBD resync checks
1136
- Fixed a couple of issues with exports and snapshot errors
1137
- Fixed a couple of issues in instance listing
1138
- Added display of the disk size in ``gnt-instance info``
1139
- Fixed checking for valid OSes in instance creation
1140
- Fixed handling of the "vcpus" parameter in instance listing and in
1141
  general of invalid parameters
1142
- Fixed http server library, and thus RAPI, to handle invalid
1143
  username/password combinations correctly; this means that now they
1144
  report unauthorized for queries too, not only for modifications,
1145
  allowing earlier detect of configuration problems
1146
- Added a new "role" node list field, equivalent to the master/master
1147
  candidate/drained/offline flags combinations
1148
- Fixed cluster modify and changes of candidate pool size
1149
- Fixed cluster verify error messages for wrong files on regular nodes
1150
- Fixed a couple of issues with node demotion from master candidate role
1151
- Fixed node readd issues
1152
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1153
- Added a new ``--no-voting`` option for masterfailover to fix failover
1154
  on two-nodes clusters when the former master node is unreachable
1155
- Added instance reinstall over RAPI
1156

    
1157

    
1158
Version 2.0.1
1159
-------------
1160

    
1161
*(Released Tue, 16 Jun 2009)*
1162

    
1163
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1164
  allow re-adding the start in single-user option (regression from 1.2)
1165
- the watcher writes the instance status to a file, to allow monitoring
1166
  to report the instance status (from the master) based on cached
1167
  results of the watcher's queries; while this can get stale if the
1168
  watcher is being locked due to other work on the cluster, this is
1169
  still an improvement
1170
- the watcher now also restarts the node daemon and the rapi daemon if
1171
  they died
1172
- fixed the watcher to handle full and drained queue cases
1173
- hooks export more instance data in the environment, which helps if
1174
  hook scripts need to take action based on the instance's properties
1175
  (no longer need to query back into ganeti)
1176
- instance failovers when the instance is stopped do not check for free
1177
  RAM, so that failing over a stopped instance is possible in low memory
1178
  situations
1179
- rapi uses queries for tags instead of jobs (for less job traffic), and
1180
  for cluster tags it won't talk to masterd at all but read them from
1181
  ssconf
1182
- a couple of error handling fixes in RAPI
1183
- drbd handling: improved the error handling of inconsistent disks after
1184
  resync to reduce the frequency of "there are some degraded disks for
1185
  this instance" messages
1186
- fixed a bug in live migration when DRBD doesn't want to reconnect (the
1187
  error handling path called a wrong function name)
1188

    
1189

    
1190
Version 2.0.0 final
1191
-------------------
1192

    
1193
*(Released Wed, 27 May 2009)*
1194

    
1195
- no changes from rc5
1196

    
1197

    
1198
Version 2.0 release candidate 5
1199
-------------------------------
1200

    
1201
*(Released Wed, 20 May 2009)*
1202

    
1203
- fix a couple of bugs (validation, argument checks)
1204
- fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1205
- some small improvements to RAPI and IAllocator
1206
- make watcher automatically start the master daemon if down
1207

    
1208

    
1209
Version 2.0 release candidate 4
1210
-------------------------------
1211

    
1212
*(Released Mon, 27 Apr 2009)*
1213

    
1214
- change the OS list to not require locks; this helps with big clusters
1215
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1216
  volume group is broken
1217
- ``gnt-instance info``, without any arguments, doesn't run for all
1218
  instances anymore; either pass ``--all`` or pass the desired
1219
  instances; this helps against mistakes on big clusters where listing
1220
  the information for all instances takes a long time
1221
- miscellaneous doc and man pages fixes
1222

    
1223

    
1224
Version 2.0 release candidate 3
1225
-------------------------------
1226

    
1227
*(Released Wed, 8 Apr 2009)*
1228

    
1229
- Change the internal locking model of some ``gnt-node`` commands, in
1230
  order to reduce contention (and blocking of master daemon) when
1231
  batching many creation/reinstall jobs
1232
- Fixes to Xen soft reboot
1233
- No longer build documentation at build time, instead distribute it in
1234
  the archive, in order to reduce the need for the whole docbook/rst
1235
  toolchains
1236

    
1237

    
1238
Version 2.0 release candidate 2
1239
-------------------------------
1240

    
1241
*(Released Fri, 27 Mar 2009)*
1242

    
1243
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1244
- Fix watcher startup sequence, improves the behaviour of busy clusters
1245
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1246
  replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1247
  bind address and other places
1248
- Some documentation fixes and updates
1249

    
1250

    
1251
Version 2.0 release candidate 1
1252
-------------------------------
1253

    
1254
*(Released Mon, 2 Mar 2009)*
1255

    
1256
- More documentation updates, now all docs should be more-or-less
1257
  up-to-date
1258
- A couple of small fixes (mixed hypervisor clusters, offline nodes,
1259
  etc.)
1260
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1261
  and KVM)
1262
- Fix an issue related to $libdir/run/ganeti and cluster creation
1263

    
1264

    
1265
Version 2.0 beta 2
1266
------------------
1267

    
1268
*(Released Thu, 19 Feb 2009)*
1269

    
1270
- Xen PVM and KVM have switched the default value for the instance root
1271
  disk to the first partition on the first drive, instead of the whole
1272
  drive; this means that the OS installation scripts must be changed
1273
  accordingly
1274
- Man pages have been updated
1275
- RAPI has been switched by default to HTTPS, and the exported functions
1276
  should all work correctly
1277
- RAPI v1 has been removed
1278
- Many improvements to the KVM hypervisor
1279
- Block device errors are now better reported
1280
- Many other bugfixes and small improvements
1281

    
1282

    
1283
Version 2.0 beta 1
1284
------------------
1285

    
1286
*(Released Mon, 26 Jan 2009)*
1287

    
1288
- Version 2 is a general rewrite of the code and therefore the
1289
  differences are too many to list, see the design document for 2.0 in
1290
  the ``doc/`` subdirectory for more details
1291
- In this beta version there is not yet a migration path from 1.2 (there
1292
  will be one in the final 2.0 release)
1293
- A few significant changes are:
1294

    
1295
  - all commands are executed by a daemon (``ganeti-masterd``) and the
1296
    various ``gnt-*`` commands are just front-ends to it
1297
  - all the commands are entered into, and executed from a job queue,
1298
    see the ``gnt-job(8)`` manpage
1299
  - the RAPI daemon supports read-write operations, secured by basic
1300
    HTTP authentication on top of HTTPS
1301
  - DRBD version 0.7 support has been removed, DRBD 8 is the only
1302
    supported version (when migrating from Ganeti 1.2 to 2.0, you need
1303
    to migrate to DRBD 8 first while still running Ganeti 1.2)
1304
  - DRBD devices are using statically allocated minor numbers, which
1305
    will be assigned to existing instances during the migration process
1306
  - there is support for both Xen PVM and Xen HVM instances running on
1307
    the same cluster
1308
  - KVM virtualization is supported too
1309
  - file-based storage has been implemented, which means that it is
1310
    possible to run the cluster without LVM and DRBD storage, for
1311
    example using a shared filesystem exported from shared storage (and
1312
    still have live migration)
1313

    
1314

    
1315
Version 1.2.7
1316
-------------
1317

    
1318
*(Released Tue, 13 Jan 2009)*
1319

    
1320
- Change the default reboot type in ``gnt-instance reboot`` to "hard"
1321
- Reuse the old instance mac address by default on instance import, if
1322
  the instance name is the same.
1323
- Handle situations in which the node info rpc returns incomplete
1324
  results (issue 46)
1325
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1326
- Improved version of batcher:
1327

    
1328
  - state file support
1329
  - instance mac address support
1330
  - support for HVM clusters/instances
1331

    
1332
- Add an option to show the number of cpu sockets and nodes in
1333
  ``gnt-node list``
1334
- Support OSes that handle more than one version of the OS api (but do
1335
  not change the current API in any other way)
1336
- Fix ``gnt-node migrate``
1337
- ``gnt-debug`` man page
1338
- Fixes various more typos and small issues
1339
- Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1340

    
1341

    
1342
Version 1.2.6
1343
-------------
1344

    
1345
*(Released Wed, 24 Sep 2008)*
1346

    
1347
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1348
  type of disk exported to fully virtualized instances.
1349
- provide access to the serial console of HVM instances
1350
- instance auto_balance flag, set by default. If turned off it will
1351
  avoid warnings on cluster verify if there is not enough memory to fail
1352
  over an instance. in the future it will prevent automatically failing
1353
  it over when we will support that.
1354
- batcher tool for instance creation, see ``tools/README.batcher``
1355
- ``gnt-instance reinstall --select-os`` to interactively select a new
1356
  operating system when reinstalling an instance.
1357
- when changing the memory amount on instance modify a check has been
1358
  added that the instance will be able to start. also warnings are
1359
  emitted if the instance will not be able to fail over, if auto_balance
1360
  is true.
1361
- documentation fixes
1362
- sync fields between ``gnt-instance list/modify/add/import``
1363
- fix a race condition in drbd when the sync speed was set after giving
1364
  the device a remote peer.
1365

    
1366

    
1367

1371

    
1372
- note: the allowed size and number of tags per object were reduced
1373

- experimental migration (and live migration) support, read the man page
1381
  for ``gnt-instance migrate``
1382
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1383
  has some small improvements in handling its state file
1384

    
1385

    
1386
Version 1.2.4
1387
-------------
1388

    
1389
*(Released Fri, 13 Jun 2008)*
1390

    
1391
- Experimental readonly, REST-based remote API implementation;
1392
  automatically started on master node, TCP port 5080, if enabled by
1393
  ``--enable-rapi`` parameter to configure script.
1394
- Instance allocator support. Add and import instance accept a
1395
  ``--iallocator`` parameter, and call that instance allocator to decide
1396
  which node to use for the instance. The iallocator document describes
1397
  what's expected from an allocator script.
1398
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1399
  ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1400
  node is lost there is still enough memory to fail over the instances
1401
  that reside on it.
1402
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1403
  ``gnt-cluster verify``, to check for site-specific compliance. All the
1404
  hooks will run, and their output, if any, will be displayed. Any
1405
  failing hook will make the verification return an error value.
1406
- ``gnt-cluster verify`` now checks that its peers are reachable on the
1407
  primary and secondary interfaces
1408
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1409
  that is still declared as part of the cluster and has failed.
1410
- ``gnt-* list`` commands now accept a new ``-o +field`` way of
1411
  specifying output fields, that just adds the chosen fields to the
1412
  default ones.
1413
- ``gnt-backup`` now has a new ``remove`` command to delete an existing
1414
  export from the filesystem.
1415
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1416
  have been added. Using them you can enable/disable acpi and pae
1417
  support, and specify a path for a cd image to be exported to the
1418
  instance. These parameters as the name suggest only work on HVM
1419
  clusters.
1420
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1421
  PAE support will be set to the previously hardcoded values, but the
1422
  (previously hardcoded) path to the CDROM ISO image will be unset and
1423
  if required, needs to be set manually with ``gnt-instance modify``
1424
  after the upgrade.
1425
- The address to which an instance's VNC console is bound is now
1426
  selectable per-instance, rather than being cluster wide. Of course
1427
  this only applies to instances controlled via VNC, so currently just
1428
  applies to HVM clusters.
1429

1431
Version 1.2.3
1432
-------------
1433

    
1434
*(Released Mon, 18 Feb 2008)*
1435

    
1436
- more tweaks to the disk activation code (especially helpful for DRBD)
1437
- change the default ``gnt-instance list`` output format, now there is
1438
  one combined status field (see the manpage for the exact values this
1439
  field will have)
1440
- some more fixes for the mac export to hooks change
1441
- make Ganeti not break with DRBD 8.2.x (which changed the version
1442
  format in ``/proc/drbd``) (issue 24)
1443
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1444
  template, allowing migration from DRBD0.7+MD to DRBD8

1458
- fix ``gnt-backup list`` with down nodes (issue 21)
1459
