7 *(Released Mon, 28 Feb 2011)*
9 A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
10 that this feature wiped the disks of the wrong instance, leading to loss
15 - fixed title of query field containing instance name
16 - expanded the glossary in the documentation
17 - fixed one unittest (internal issue)
23 *(Released Mon, 21 Feb 2011)*
25 A number of bug fixes plus just a couple functionality changes.
27 On the user-visible side, the ``gnt-* list`` command output has changed
28 with respect to “special” field states. The current rc1 style of display
29 can be re-enabled by passing a new ``-v, --verbose`` flag, but in the
30 default output mode special fields are displayed as follows:
32 - offline field: ``*``
33 - unavailable/not applicable: ``-``
34 - data missing (RPC failure): ``?``
35 - unknown field: ``??``
37 Another user-visible change is the addition of ``--force-join`` to
42 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
43 - fixed regression in RAPI/instance reinstall where all parameters were
44 required (instead of optional)
45 - fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
46 - fixed iallocator usage (offline nodes were not considered offline)
47 - fixed ``gnt-node list`` with respect to non-vm_capable nodes
48 - fixed hypervisor and OS parameter validation with respect to
50 - fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
52 - fixed ``tools/listrunner`` with respect to agent-based usage
58 *(Released Fri, 4 Feb 2011)*
60 Many changes and fixes since the beta1 release. While there were some
61 internal changes, the code has been mostly stabilised for the RC
64 Note: the dumb allocator was removed in this release, as it was not kept
65 up-to-date with the IAllocator protocol changes. It is recommended to
66 use the ``hail`` command from the ganeti-htools package.
68 Note: the 2.4 and up versions of Ganeti are not compatible with the
69 0.2.x branch of ganeti-htools. You need to upgrade to
70 ganeti-htools-0.3.0 (or later).
72 Regressions fixed from 2.3
73 ~~~~~~~~~~~~~~~~~~~~~~~~~~
75 - Fixed the ``gnt-cluster verify-disks`` command

79 - Fixed wrong headers in instance listing for field aliases
84 - Fixed corner case in KVM handling of NICs
85 - Fixed many cases of wrong handling of non-vm_capable nodes
86 - Fixed a bug where a missing instance symlink was not possible to

88 activate-disks`` does it)
89 - Fixed the volume group name as reported by ``gnt-cluster
91 - Increased timeouts for the import-export code, hopefully leading to
92 fewer aborts due network or instance timeouts
93 - Fixed bug in ``gnt-node list-storage``

95 initialisation, but only at the first watcher run
96 - Fixed many bugs in the OOB implementation
97 - Fixed watcher behaviour in presence of instances with offline
99 - Fixed instance list output for instances running on the wrong node
100 - a few fixes to the cluster-merge tool, but it still cannot merge
101 multi-node groups (currently it is not recommended to use this tool)
107 - Improved network configuration for the KVM hypervisor
108 - Added e1000 as a supported NIC for Xen-HVM
109 - Improved the lvmstrap tool to also be able to use partitions, as
110 opposed to full disks
111 - Improved speed of disk wiping (the cluster parameter
112 ``prealloc_wipe_disks``, so that it has a low impact on the total time
113 of instance creations
114 - Added documentation for the OS parameters
115 - Changed ``gnt-instance deactivate-disks`` so that it can work if the
116 hypervisor is not responding
117 - Added display of blacklisted and hidden OS information in
119 - Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
120 NIC and node parameters, which might create problems with currently
121 invalid (but undetected) configuration files, but prevents validation
122 failures when unrelated parameters are modified
123 - Changed cluster initialisation to wait for the master daemon to become
125 - Expanded the RAPI interface:
127 - Added config redistribution resource
128 - Added activation/deactivation of instance disks
129 - Added export of console information
131 - Implemented log file reopening on SIGHUP, which allows using
132 logrotate(8) for the Ganeti log files
133 - Added a basic OOB helper script as an example
139 *(Released Fri, 14 Jan 2011)*
144 - Fixed timezone issues when formatting timestamps

158 - Added commands to list available fields:
160 - ``gnt-node list-fields``
161 - ``gnt-group list-fields``
162 - ``gnt-instance list-fields``
164 - Updated documentation and man pages
169 - Moved ``rapi_users`` file into separate directory, now named
170 ``…/ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
172 - Added new tool for running commands on many machines,
173 ``tools/ganeti-listrunner``
174 - Implemented more verbose result in ``OpInstanceConsole`` opcode, also

178 - Added support for non-partitioned md disks in ``lvmstrap``
179 - Added script to gracefully power off KVM instances
180 - Split ``utils`` module into smaller parts
181 - Changed query operations to return more detailed information, e.g.
182 whether an information is unavailable due to an offline node. To use
183 this new functionality, the LUXI call ``Query`` must be used. Field
184 information is now stored by the master daemon and can be retrieved
185 using ``QueryFields``. Instances, nodes and groups can also be queried
186 using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
187 exposed via RAPI). The following commands make use of this
188 infrastructure change:
191 - ``gnt-group list-fields``
193 - ``gnt-node list-fields``
194 - ``gnt-instance list``
195 - ``gnt-instance list-fields``
196 - ``gnt-debug locks``

281 - Simplify and extend the environment variables for instance OS scripts
282 - Added new node flags, ``master_capable`` and ``vm_capable``
283 - Added optional instance disk wiping prior during allocation. This is a
284 cluster-wide option and can be set/modified using
285 ``gnt-cluster {init,modify} --prealloc-wipe-disks``.
286 - Added IPv6 support, see :doc:`design document <design-2.3>` and
288 - Added a new watcher option (``--ignore-pause``)

408 locks is expected for a later 2.2.x release
409 - Fixed dry-run behaviour with many commands
410 - Support ``ssh-agent`` again when adding nodes
411 - Many additional bugfixes
417 *(Released Fri, 30 Jul 2010)*
419 Important change: the internal RPC mechanism between Ganeti nodes has
420 changed from using a home-grown http library (based on the Python base
421 libraries) to use the PycURL library. This requires that PycURL is
422 installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
423 against GnuTLS by default. cURL's support for GnuTLS had known issues
424 before cURL 7.21.0 and we recommend using the latest cURL release or
425 linking against OpenSSL. Most other distributions already link PycURL
426 and cURL against OpenSSL. The command::
428 python -c 'import pycurl; print pycurl.version'
430 can be used to determine the libraries PycURL and cURL are linked
433 Other significant changes:
435 - Rewrote much of the internals of the job queue, in order to achieve
436 better parallelism; this decouples job query operations from the job
437 processing, and it should allow much nicer behaviour of the master
438 daemon under load, and it also has uncovered some long-standing bugs
439 related to the job serialisation (now fixed)
440 - Added a default iallocator setting to the cluster parameters,
441 eliminating the need to always pass nodes or an iallocator for
442 operations that require selection of new node(s)
443 - Added experimental support for the LXC virtualization method
444 - Added support for OS parameters, which allows the installation of
445 instances to pass parameter to OS scripts in order to customise the
447 - Added a hypervisor parameter controlling the migration type (live or
448 non-live), since hypervisors have various levels of reliability; this
449 has renamed the 'live' parameter to 'mode'
450 - Added a cluster parameter ``reserved_lvs`` that denotes reserved
451 logical volumes, meaning that cluster verify will ignore them and not
452 flag their presence as errors
453 - The watcher will now reset the error count for failed instances after
454 8 hours, thus allowing self-healing if the problem that caused the
455 instances to be down/fail to start has cleared in the meantime
456 - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
457 check for, and warn, if the drbd module parameter ``usermode_helper``
458 is not consistent with the cluster-wide setting; this is needed to
459 make diagnose easier of failed drbd creations
460 - Started adding base IPv6 support, but this is not yet
461 enabled/available for use
462 - Rename operations (cluster, instance) will now return the new name,
463 which is especially useful if a short name was passed in
464 - Added support for instance migration in RAPI
465 - Added a tool to pre-configure nodes for the SSH setup, before joining
466 them to the cluster; this will allow in the future a simplified model
467 for node joining (but not yet fully enabled in 2.2); this needs the
468 paramiko python library
469 - Fixed handling of name-resolving errors
470 - Fixed consistency of job results on the error path
471 - Fixed master-failover race condition when executed multiple times in
473 - Fixed many bugs related to the job queue (mostly introduced during the
474 2.2 development cycle, so not all are impacting 2.1)
475 - Fixed instance migration with missing disk symlinks
476 - Fixed handling of unknown jobs in ``gnt-job archive``
477 - And many other small fixes/improvements
481 - Enhanced both the unittest and the QA coverage
482 - Switched the opcode validation to a generic model, and extended the
483 validation to all opcode parameters
484 - Changed more parts of the code that write shell scripts to use the
486 - Switched the master daemon to use the asyncore library for the Luxi
493 *(Released Thu, 17 Jun 2010)*
495 - Added tool (``move-instance``) and infrastructure to move instances
496 between separate clusters (see :doc:`separate documentation
497 <move-instance>` and :doc:`design document <design-2.2>`)
498 - Added per-request RPC timeout
499 - RAPI now requires a Content-Type header for requests with a body (e.g.
500 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
501 :rfc:`2616` (HTTP/1.1), section 7.2.1)
502 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
504 - Implemented initial support for running Ganeti daemons as separate
505 users, see configure-time flags ``--with-user-prefix`` and
506 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
508 - Instances can be removed after export (``gnt-backup export
510 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
511 key (instead of 1024 bit)
512 - Added new cluster configuration file for cluster domain secret
513 - Import/export now use SSL instead of SSH
514 - Added support for showing estimated time when exporting an instance,
515 see the ``ganeti-os-interface(7)`` manpage and look for
522 *(Released Tue, 16 Nov 2010)*
524 Some more bugfixes. Unless critical bugs occur, this will be the last
527 - Fix case of MAC special-values
528 - Fix mac checker regex
529 - backend: Fix typo causing “out of range” error
530 - Add missing --units in gnt-instance list man page
536 *(Released Tue, 24 Aug 2010)*
539 - Don't ignore secondary node silently on non-mirrored disk templates
541 - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
542 - Fix usb_mouse parameter breaking with vnc_console (issue 109)
543 - Properly document the usb_mouse parameter
544 - Fix path in ganeti-rapi(8) (issue 116)
545 - Adjust error message when the ganeti user's .ssh directory is
547 - Add same-node-check when changing the disk template to drbd
553 *(Released Fri, 16 Jul 2010)*
556 - Add an option to only select some reboot types during qa/burnin.
557 (on some hypervisors consequent reboots are not supported)
558 - Fix infrequent race condition in master failover. Sometimes the old
559 master ip address would be still detected as up for a short time
560 after it was removed, causing failover to fail.
561 - Decrease mlockall warnings when the ctypes module is missing. On
562 Python 2.4 we support running even if no ctypes module is installed,
563 but we were too verbose about this issue.
564 - Fix building on old distributions, on which man doesn't have a
566 - Fix RAPI not to ignore the MAC address on instance creation
567 - Implement the old instance creation format in the RAPI client.
573 *(Released Thu, 01 Jul 2010)*
575 A small bugfix release:
576 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
577 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
578 a non-existing option
579 - Fix instance create: the --force-variant option was ignored
580 - Improve pylint 0.21 compatibility and warnings with Python 2.6
581 - Fix modify node storage with non-FQDN arguments
582 - Fix RAPI client to authenticate under Python 2.6 when used
583 for more than 5 requests needing authentication
584 - Fix gnt-instance modify -t (storage) giving a wrong error message
585 when converting a non-shutdown drbd instance to plain
591 *(Released Fri, 18 Jun 2010)*
593 A small bugfix release:
595 - Fix live migration of KVM instances started with older Ganeti
596 versions which had fewer hypervisor parameters
597 - Fix gnt-instance grow-disk on down instances
598 - Fix an error-reporting bug during instance migration
599 - Better checking of the ``--net`` and ``--disk`` values, to avoid
600 silently ignoring broken ones
601 - Fix an RPC error reporting bug affecting, for example, RAPI client
603 - Fix bug triggered by different API version os-es on different nodes
604 - Fix a bug in instance startup with custom hvparams: OS level
605 parameters would fail to be applied.
606 - Fix the RAPI client under Python 2.6 (but more work is needed to
607 make it work completely well with OpenSSL)
608 - Fix handling of errors when resolving names from DNS
614 *(Released Thu, 3 Jun 2010)*
616 A medium sized development cycle. Some new features, and some
617 fixes/small improvements/cleanups.
622 The node deamon now tries to mlock itself into memory, unless the
623 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
624 its logs, and falls back to console logging. This allows emergency
625 features such as ``gnt-node powercycle`` to work even in the event of a
626 broken node disk (tested offlining the disk hosting the node's
627 filesystem and dropping its memory caches; don't try this at home)
629 KVM: add vhost-net acceleration support. It can be tested with a new
630 enough version of the kernel and of qemu-kvm.
632 KVM: Add instance chrooting feature. If you use privilege dropping for
633 your VMs you can also now force them to chroot to an empty directory,
634 before starting the emulated guest.
636 KVM: Add maximum migration bandwith and maximum downtime tweaking
637 support (requires a new-enough version of qemu-kvm).
639 Cluster verify will now warn if the master node doesn't have the master
642 Add a new (incompatible) instance creation request format to RAPI which
643 supports all parameters (previously only a subset was supported, and it
644 wasn't possible to extend the old format to accomodate all the new
645 features. The old format is still supported, and a client can check for
646 this feature, before using it, by checking for its presence in the
647 ``features`` RAPI resource.
649 Now with ancient latin support. Try it passing the ``--roman`` option to
650 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
651 (requires the python-roman module to be installed, in order to work).
656 As usual many internal code refactorings, documentation updates, and
659 - Lots of improvements and cleanups to the experimental Remote API
660 (RAPI) client library.
661 - A new unit test suite for the core daemon libraries.
662 - A fix to creating missing directories makes sure the umask is not
663 applied anymore. This enforces the same directory permissions
665 - Better handling terminating daemons with ctrl+c (used when running
666 them in debugging mode).
667 - Fix a race condition in live migrating a KVM instance, when stat()
668 on the old proc status file returned EINVAL, which is an unexpected
670 - Fixed manpage checking with newer man and utf-8 charachters. But now
671 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
677 *(Released Fri, 7 May 2010)*
679 Fix a bug which prevented untagged KVM instances from starting.
685 *(Released Fri, 7 May 2010)*
687 Another release with a long development cycle, during which many
688 different features were added.
693 The KVM hypervisor now can run the individual instances as non-root, to
694 reduce the impact of a VM being hijacked due to bugs in the
695 hypervisor. It is possible to run all instances as a single (non-root)
696 user, to manually specify a user for each instance, or to dynamically
697 allocate a user out of a cluster-wide pool to each instance, with the
698 guarantee that no two instances will run under the same user ID on any
701 An experimental RAPI client library, that can be used standalone
702 (without the other Ganeti libraries), is provided in the source tree as
703 ``lib/rapi/client.py``. Note this client might change its interface in
704 the future, as we iterate on its capabilities.
706 A new command, ``gnt-cluster renew-crypto`` has been added to easily
707 replace the cluster's certificates and crypto keys. This might help in
708 case they have been compromised, or have simply expired.
710 A new disk option for instance creation has been added that allows one
711 to "adopt" currently existing logical volumes, with data
712 preservation. This should allow easier migration to Ganeti from
713 unmanaged (or managed via other software) instances.
715 Another disk improvement is the possibility to convert between redundant
716 (DRBD) and plain (LVM) disk configuration for an instance. This should
717 allow better scalability (starting with one node and growing the
718 cluster, or shrinking a two-node cluster to one node).
720 A new feature that could help with automated node failovers has been
721 implemented: if a node sees itself as offline (by querying the master
722 candidates), it will try to shutdown (hard) all instances and any active
723 DRBD devices. This reduces the risk of duplicate instances if an
724 external script automatically failovers the instances on such nodes. To
725 enable this, the cluster parameter ``maintain_node_health`` should be
726 enabled; in the future this option (per the name) will enable other
727 automatic maintenance features.
729 Instance export/import now will reuse the original instance
730 specifications for all parameters; that means exporting an instance,
731 deleting it and the importing it back should give an almost identical
732 instance. Note that the default import behaviour has changed from
733 before, where it created only one NIC; now it recreates the original
736 Cluster verify has added a few new checks: SSL certificates validity,
737 /etc/hosts consistency across the cluster, etc.
742 As usual, many internal changes were done, documentation fixes,
745 - Fixed cluster initialization with disabled cluster storage (regression
747 - File-based storage supports growing the disks
748 - Fixed behaviour of node role changes
749 - Fixed cluster verify for some corner cases, plus a general rewrite of
750 cluster verify to allow future extension with more checks
751 - Fixed log spamming by watcher and node daemon (regression introduced
753 - Fixed possible validation issues when changing the list of enabled
755 - Fixed cleanup of /etc/hosts during node removal
756 - Fixed RAPI response for invalid methods
757 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
758 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
759 from ide disks, etc.)
760 - Allow OS changes without re-installation (to record a changed OS
761 outside of Ganeti, or to allow OS renames)
762 - Allow instance creation without OS installation (useful for example if
763 the OS will be installed manually, or restored from a backup not in
765 - Implemented option to make cluster ``copyfile`` use the replication
767 - Added list of enabled hypervisors to ssconf (possibly useful for
769 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
771 - A partial form of node re-IP is possible via node readd, which now
772 allows changed node primary IP
773 - Command line utilities now show an informational message if the job is
775 - The logs of the master daemon now show the PID/UID/GID of the
782 *(Released Fri, 12 Mar 2010)*
784 During the 2.1.0 long release candidate cycle, a lot of improvements and
785 changes have accumulated with were released later as 2.1.1.
790 The node evacuate command (``gnt-node evacuate``) was significantly
791 rewritten, and as such the IAllocator protocol was changed - a new
792 request type has been added. This unfortunate change during a stable
793 series is designed to improve performance of node evacuations; on
794 clusters with more than about five nodes and which are well-balanced,
795 evacuation should proceed in parallel for all instances of the node
796 being evacuated. As such, any existing IAllocator scripts need to be
797 updated, otherwise the above command will fail due to the unknown
798 request. The provided "dumb" allocator has not been updated; but the
799 ganeti-htools package supports the new protocol since version 0.2.4.
801 Another important change is increased validation of node and instance
802 names. This might create problems in special cases, if invalid host
803 names are being used.
805 Also, a new layer of hypervisor parameters has been added, that sits at
806 OS level between the cluster defaults and the instance ones. This allows
807 customisation of virtualization parameters depending on the installed
808 OS. For example instances with OS 'X' may have a different KVM kernel
809 (or any other parameter) than the cluster defaults. This is intended to
810 help managing a multiple OSes on the same cluster, without manual
811 modification of each instance's parameters.
813 A tool for merging clusters, ``cluster-merge``, has been added in the
819 - Improved the int/float conversions that should make the code more
820 robust in face of errors from the node daemons
821 - Fixed the remove node code in case of internal configuration errors
822 - Fixed the node daemon behaviour in face of inconsistent queue
823 directory (e.g. read-only file-system where we can't open the files
825 - Fixed the behaviour of gnt-node modify for master candidate demotion;
826 now it either aborts cleanly or, if given the new “auto_promote”
827 parameter, will automatically promote other nodes as needed
828 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
829 completely prevent Ganeti from working
830 - Fixed bug for instance export when not all disks were successfully
832 - Fixed behaviour of node add when the new node is slow in starting up
834 - Fixed handling of signals in the LUXI client, which should improve
835 behaviour of command-line scripts
836 - Added checks for invalid node/instance names in the configuration (now
837 flagged during cluster verify)
838 - Fixed watcher behaviour for disk activation errors
839 - Fixed two potentially endless loops in http library, which led to the
840 RAPI daemon hanging and consuming 100% CPU in some cases
841 - Fixed bug in RAPI daemon related to hashed passwords
842 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
844 - Enhanced compatibility with non-Debian OSes, but not using absolute
845 path in some commands and allowing customisation of the ssh
846 configuration directory
847 - Fixed possible future issue with new Python versions by abiding to the
848 proper use of ``__slots__`` attribute on classes
849 - Added checks that should prevent directory traversal attacks
850 - Many documentation fixes based on feedback from users
855 - Added an “early_release” more for instance replace disks and node
856 evacuate, where we release locks earlier and thus allow higher
857 parallelism within the cluster
858 - Added watcher hooks, intended to allow the watcher to restart other
859 daemons (e.g. from the ganeti-nbma project), but they can be used of
860 course for any other purpose
861 - Added a compile-time disable for DRBD barriers, to increase
862 performance if the administrator trusts the power supply or the
863 storage system to not lose writes
864 - Added the option of using syslog for logging instead of, or in
865 addition to, Ganeti's own log files
866 - Removed boot restriction for paravirtual NICs for KVM, recent versions
867 can indeed boot from a paravirtual NIC
868 - Added a generic debug level for many operations; while this is not
869 used widely yet, it allows one to pass the debug value all the way to
871 - Enhanced the hooks environment for instance moves (failovers,
872 migrations) where the primary/secondary nodes changed during the
873 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
874 - Enhanced data validations for many user-supplied values; one important
875 item is the restrictions imposed on instance and node names, which
876 might reject some (invalid) host names
877 - Add a configure-time option to disable file-based storage, if it's not
878 needed; this allows greater security separation between the master
879 node and the other nodes from the point of view of the inter-node RPC
881 - Added user notification in interactive tools if job is waiting in the
882 job queue or trying to acquire locks
883 - Added log messages when a job is waiting for locks
884 - Added filtering by node tags in instance operations which admit
885 multiple instances (start, stop, reboot, reinstall)
886 - Added a new tool for cluster mergers, ``cluster-merge``
887 - Parameters from command line which are of the form ``a=b,c=d`` can now
888 use backslash escapes to pass in values which contain commas,
889 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
891 - For KVM, the instance name is the first parameter passed to KVM, so
892 that it's more visible in the process list
898 *(Released Tue, 2 Mar 2010)*

920 ``bootloader_path`` and ``bootloader_args``)
921 - Added the ``use_localtime`` option for the xen-hvm and kvm
922 hypervisors, and the default value for this has changed to false (in
923 2.0 xen-hvm always enabled it)

940 - Added OpCodes to evacuate or migrate all instances on a node
941 - Added new command to list storage elements on nodes (``gnt-node
942 list-storage``) and modify them (``gnt-node modify-storage``)
943 - Added new ssconf files with master candidate IP address
944 (``ssconf_master_candidates_ips``), node primary IP address
945 (``ssconf_node_primary_ips``) and node secondary IP address
946 (``ssconf_node_secondary_ips``)
947 - Added ``ganeti-confd`` and a client library to query the Ganeti
948 configuration via UDP
949 - Added ability to run hooks after cluster initialization and before

963 ``--verbose`` to restore previous behaviour)
964 - Added UUIDs to the main config entities (cluster, nodes, instances)
965 - Added support for OS variants
966 - Added support for hashed passwords in the Ganeti remote API users file
968 - Added option to specify maximum timeout on instance shutdown
969 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
970 - Added new helper script to start and stop Ganeti daemons
971 (``daemon-util``), with the intent to reduce the work necessary to
972 adjust Ganeti for non-Debian distributions and to start/stop daemons
974 - Added more unittests
975 - Fixed critical bug in ganeti-masterd startup
976 - Removed the configure-time ``kvm-migration-port`` parameter, this is
977 now customisable at the cluster level for both the KVM and Xen
978 hypervisors using the new ``migration_port`` parameter
979 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
980 reinstalling an instance
981 - Allowed ``@`` in tag names

1004 - Improve data validation in the master of values returned from nodes
1010 *(Released Thu, 17 Dec 2009)*

1013 allows local and remote execution of arbitrary executables
1014 - Fix failure of gnt-node list during instance removal
1015 - Ship the RAPI documentation in the archive
1021 *(Released Wed, 30 Sep 2009)*
1023 - Fixed many wrong messages
1024 - Fixed a few bugs related to the locking library
1025 - Fixed MAC checking at instance creation time
1026 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1027 - Fixed a few issues related to signal handling in both daemons and
1029 - Fixed the example startup script provided
1030 - Fixed insserv dependencies in the example startup script (patch from
1032 - Fixed handling of drained nodes in the iallocator framework
1033 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1035 - Fixed error related to invalid job IDs in job polling
1036 - Fixed job/opcode persistence on unclean master shutdown
1037 - Fixed handling of partial job processing after unclean master
1039 - Fixed error reporting from LUs, previously all errors were converted
1040 into execution errors
1041 - Fixed error reporting from burnin
1042 - Decreased significantly the memory usage of the job queue
1043 - Optimised slightly multi-job submission
1044 - Optimised slightly opcode loading
1045 - Backported the multi-job submit framework from the development
1046 branch; multi-instance start and stop should be faster
1047 - Added script to clean archived jobs after 21 days; this will reduce
1048 the size of the queue directory
1049 - Added some extra checks in disk size tracking
1050 - Added an example ethers hook script
1051 - Added a cluster parameter that prevents Ganeti from modifying of
1053 - Added more node information to RAPI responses
1054 - Added a ``gnt-job watch`` command that allows following the ouput of a
1056 - Added a bind-address option to ganeti-rapi
1057 - Added more checks to the configuration verify
1058 - Enhanced the burnin script such that some operations can be retried
1060 - Converted instance reinstall to multi-instance model
1066 *(Released Fri, 7 Aug 2009)*
1068 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1069 to allow using the pre-2.0.2 behaviour in activation, if any existing
1070 instances have mismatched disk sizes in the configuration
1071 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1072 any configuration mismatches for disk sizes
1073 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1074 failover to work on two-node clusters
1075 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1077 - Fixed detection of OS script errors in ``gnt-backup export``
1078 - Fixed exit code of ``gnt-backup export``
1084 *(Released Fri, 17 Jul 2009)*
1086 - Added experimental support for stripped logical volumes; this should
1087 enhance performance but comes with a higher complexity in the block
1088 device handling; stripping is only enabled when passing
1089 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1090 affected even in the non-stripped mode
1091 - Improved resiliency against transient failures at the end of DRBD
1092 resyncs, and in general of DRBD resync checks
1093 - Fixed a couple of issues with exports and snapshot errors
1094 - Fixed a couple of issues in instance listing
1095 - Added display of the disk size in ``gnt-instance info``
1096 - Fixed checking for valid OSes in instance creation
1097 - Fixed handling of the "vcpus" parameter in instance listing and in
1098 general of invalid parameters
1099 - Fixed http server library, and thus RAPI, to handle invalid
1100 username/password combinations correctly; this means that now they
1101 report unauthorized for queries too, not only for modifications,
1102 allowing earlier detect of configuration problems
1103 - Added a new "role" node list field, equivalent to the master/master
1104 candidate/drained/offline flags combinations
1105 - Fixed cluster modify and changes of candidate pool size
1106 - Fixed cluster verify error messages for wrong files on regular nodes
1107 - Fixed a couple of issues with node demotion from master candidate role
1108 - Fixed node readd issues
1109 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1110 - Added a new ``--no-voting`` option for masterfailover to fix failover
1111 on two-nodes clusters when the former master node is unreachable
1112 - Added instance reinstall over RAPI
1118 *(Released Tue, 16 Jun 2009)*
1120 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1121 allow re-adding the start in single-user option (regression from 1.2)
1122 - the watcher writes the instance status to a file, to allow monitoring
1123 to report the instance status (from the master) based on cached
1124 results of the watcher's queries; while this can get stale if the
1125 watcher is being locked due to other work on the cluster, this is
1126 still an improvement
1127 - the watcher now also restarts the node daemon and the rapi daemon if
1129 - fixed the watcher to handle full and drained queue cases
1130 - hooks export more instance data in the environment, which helps if
1131 hook scripts need to take action based on the instance's properties
1132 (no longer need to query back into ganeti)
1133 - instance failovers when the instance is stopped do not check for free
1134 RAM, so that failing over a stopped instance is possible in low memory
1136 - rapi uses queries for tags instead of jobs (for less job traffic), and
1137 for cluster tags it won't talk to masterd at all but read them from
1139 - a couple of error handling fixes in RAPI
1140 - drbd handling: improved the error handling of inconsistent disks after
1141 resync to reduce the frequency of "there are some degraded disks for
1142 this instance" messages
1143 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1144 error handling path called a wrong function name)
1150 *(Released Wed, 27 May 2009)*
1152 - no changes from rc5
1155 Version 2.0 release candidate 5
1156 -------------------------------

1161 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1162 - some small improvements to RAPI and IAllocator
1163 - make watcher automatically start the master daemon if down
1166 Version 2.0 release candidate 4
1167 -------------------------------
1169 *(Released Mon, 27 Apr 2009)*
1171 - change the OS list to not require locks; this helps with big clusters
1172 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1173 volume group is broken
1174 - ``gnt-instance info``, without any arguments, doesn't run for all
1175 instances anymore; either pass ``--all`` or pass the desired
1176 instances; this helps against mistakes on big clusters where listing
1177 the information for all instances takes a long time
1178 - miscellaneous doc and man pages fixes
1181 Version 2.0 release candidate 3
1182 -------------------------------
1184 *(Released Wed, 8 Apr 2009)*
1186 - Change the internal locking model of some ``gnt-node`` commands, in
1187 order to reduce contention (and blocking of master daemon) when
1188 batching many creation/reinstall jobs
1189 - Fixes to Xen soft reboot
1190 - No longer build documentation at build time, instead distribute it in
1191 the archive, in order to reduce the need for the whole docbook/rst
1195 Version 2.0 release candidate 2
1196 -------------------------------
1198 *(Released Fri, 27 Mar 2009)*
1200 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1201 - Fix watcher startup sequence, improves the behaviour of busy clusters
1202 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1203 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1204 bind address and other places
1205 - Some documentation fixes and updates
1208 Version 2.0 release candidate 1
1209 -------------------------------
1211 *(Released Mon, 2 Mar 2009)*
1213 - More documentation updates, now all docs should be more-or-less
1215 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1217 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1219 - Fix an issue related to $libdir/run/ganeti and cluster creation
1225 *(Released Thu, 19 Feb 2009)*
1227 - Xen PVM and KVM have switched the default value for the instance root
1228 disk to the first partition on the first drive, instead of the whole
1229 drive; this means that the OS installation scripts must be changed
1231 - Man pages have been updated
1232 - RAPI has been switched by default to HTTPS, and the exported functions
1233 should all work correctly
1234 - RAPI v1 has been removed
1235 - Many improvements to the KVM hypervisor
1236 - Block device errors are now better reported
1237 - Many other bugfixes and small improvements
1243 *(Released Mon, 26 Jan 2009)*
1245 - Version 2 is a general rewrite of the code and therefore the
1246 differences are too many to list, see the design document for 2.0 in
1247 the ``doc/`` subdirectory for more details
1248 - In this beta version there is not yet a migration path from 1.2 (there
1249 will be one in the final 2.0 release)
1250 - A few significant changes are:
1252 - all commands are executed by a daemon (``ganeti-masterd``) and the
1253 various ``gnt-*`` commands are just front-ends to it
1254 - all the commands are entered into, and executed from a job queue,
1255 see the ``gnt-job(8)`` manpage
1256 - the RAPI daemon supports read-write operations, secured by basic
1257 HTTP authentication on top of HTTPS
1258 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1259 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1260 to migrate to DRBD 8 first while still running Ganeti 1.2)
1261 - DRBD devices are using statically allocated minor numbers, which
1262 will be assigned to existing instances during the migration process
1263 - there is support for both Xen PVM and Xen HVM instances running on
1265 - KVM virtualization is supported too
1266 - file-based storage has been implemented, which means that it is
1267 possible to run the cluster without LVM and DRBD storage, for
1268 example using a shared filesystem exported from shared storage (and
1269 still have live migration)
1275 *(Released Tue, 13 Jan 2009)*
1277 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1278 - Reuse the old instance mac address by default on instance import, if
1279 the instance name is the same.
1280 - Handle situations in which the node info rpc returns incomplete
1282 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1283 - Improved version of batcher:
1285 - state file support
1286 - instance mac address support
1287 - support for HVM clusters/instances
1289 - Add an option to show the number of cpu sockets and nodes in
1291 - Support OSes that handle more than one version of the OS api (but do
1292 not change the current API in any other way)
1293 - Fix ``gnt-node migrate``
1294 - ``gnt-debug`` man page
1295 - Fixes various more typos and small issues
1296 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1302 *(Released Wed, 24 Sep 2008)*
1304 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1305 type of disk exported to fully virtualized instances.
1306 - provide access to the serial console of HVM instances
1307 - instance auto_balance flag, set by default. If turned off it will
1308 avoid warnings on cluster verify if there is not enough memory to fail
1309 over an instance. in the future it will prevent automatically failing
1310 it over when we will support that.
1311 - batcher tool for instance creation, see ``tools/README.batcher``
1312 - ``gnt-instance reinstall --select-os`` to interactively select a new
1313 operating system when reinstalling an instance.
1314 - when changing the memory amount on instance modify a check has been
1315 added that the instance will be able to start. also warnings are
1316 emitted if the instance will not be able to fail over, if auto_balance
1318 - documentation fixes
1319 - sync fields between ``gnt-instance list/modify/add/import``
1320 - fix a race condition in drbd when the sync speed was set after giving
1321 the device a remote peer.
1327 *(Released Tue, 22 Jul 2008)*
1329 - note: the allowed size and number of tags per object were reduced
1330 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1331 - fixed twisted 8.x compatibility
1332 - fixed ``gnt-instance replace-disks`` with iallocator
1333 - add TCP keepalives on twisted connections to detect restarted nodes
1334 - disk increase support, see ``gnt-instance grow-disk``
1335 - implement bulk node/instance query for RAPI
1336 - add tags in node/instance listing (optional)
1337 - experimental migration (and live migration) support, read the man page
1338 for ``gnt-instance migrate``
1339 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1340 has some small improvements in handling its state file
1346 *(Released Fri, 13 Jun 2008)*
1348 - Experimental readonly, REST-based remote API implementation;
1349 automatically started on master node, TCP port 5080, if enabled by
1350 ``--enable-rapi`` parameter to configure script.
1351 - Instance allocator support. Add and import instance accept a
1352 ``--iallocator`` parameter, and call that instance allocator to decide
1353 which node to use for the instance. The iallocator document describes
1354 what's expected from an allocator script.
1355 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1356 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1357 node is lost there is still enough memory to fail over the instances
1359 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1360 ``gnt-cluster verify``, to check for site-specific compliance. All the
1361 hooks will run, and their output, if any, will be displayed. Any
1362 failing hook will make the verification return an error value.
1363 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1364 primary and secondary interfaces
1365 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1366 that is still declared as part of the cluster and has failed.
1367 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1368 specifying output fields, that just adds the chosen fields to the
1370 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1371 export from the filesystem.
1372 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1373 have been added. Using them you can enable/disable acpi and pae
1374 support, and specify a path for a cd image to be exported to the
1375 instance. These parameters as the name suggest only work on HVM
1377 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1378 PAE support will be set to the previously hardcoded values, but the
1379 (previously hardcoded) path to the CDROM ISO image will be unset and
1380 if required, needs to be set manually with ``gnt-instance modify``
1382 - The address to which an instance's VNC console is bound is now
1383 selectable per-instance, rather than being cluster wide. Of course
1384 this only applies to instances controlled via VNC, so currently just
1385 applies to HVM clusters.
1391 *(Released Mon, 18 Feb 2008)*
1393 - more tweaks to the disk activation code (especially helpful for DRBD)
1394 - change the default ``gnt-instance list`` output format, now there is
1395 one combined status field (see the manpage for the exact values this
1397 - some more fixes for the mac export to hooks change
1398 - make Ganeti not break with DRBD 8.2.x (which changed the version
1399 format in ``/proc/drbd``) (issue 24)
1400 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1401 template, allowing migration from DRBD0.7+MD to DRBD8
1407 *(Released Wed, 30 Jan 2008)*
1409 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1411 - add command aliases infrastructure and a few aliases
1412 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1413 man pages and the ``--help`` option of ``gnt-node
1414 list``/``gnt-instance list``
1415 - fix ``gnt-backup list`` with down nodes (issue 21)
1416 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1417 - fix the dist archive and add a check for including svn/git files in
1419 - some developer-related changes: improve the burnin and the QA suite,
1420 add an upload script for testing during development
1426 *(Released Wed, 16 Jan 2008)*
1428 - experimental HVM support, read the install document, section
1429 "Initializing the cluster"
1430 - allow for the PVM hypervisor per-instance kernel and initrd paths
1431 - add a new command ``gnt-cluster verify-disks`` which uses a new
1432 algorithm to improve the reconnection of the DRBD pairs if the device
1433 on the secondary node has gone away
1434 - make logical volume code auto-activate LVs at disk activation time
1435 - slightly improve the speed of activating disks
1436 - allow specification of the MAC address at instance creation time, and
1437 changing it later via ``gnt-instance modify``
1438 - fix handling of external commands that generate lots of output on
1440 - update documentation with regard to minimum version of DRBD8 supported
1446 *(Released Tue, 4 Dec 2007)*
1448 - Log the ``xm create`` output to the node daemon log on failure (to
1449 help diagnosing the error)
1450 - In debug mode, log all external commands output if failed to the logs
1451 - Change parsing of lvm commands to ignore stderr
1457 *(Released Wed, 28 Nov 2007)*
1459 - Another round of updates to the DRBD 8 code to deal with more failures
1460 in the replace secondary node operation
1461 - Some more logging of failures in disk operations (lvm, drbd)
1462 - A few documentation updates
1469 *(Released Tue, 13 Nov 2007)*
1471 - Change configuration file format from Python's Pickle to JSON.
1472 Upgrading is possible using the cfgupgrade utility.
1473 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1474 faster replace disks and is more stable (DRBD 8 has many improvements
1475 compared to DRBD 0.7)
1476 - Added command line tags support (see man pages for ``gnt-instance``,
1477 ``gnt-node``, ``gnt-cluster``)
1478 - Added instance rename support
1479 - Added multi-instance startup/shutdown
1480 - Added cluster rename support
1481 - Added ``gnt-node evacuate`` to simplify some node operations
1482 - Added instance reboot operation that can speedup reboot as compared to
1484 - Soften the requirement that hostnames are in FQDN format
1485 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
1487 - Removed dependency on debian's patched fping that uses the
1488 non-standard ``-S`` option
1489 - Now the OS definitions are searched for in multiple, configurable
1490 paths (easier for distros to package)
1491 - Some changes to the hooks infrastructure (especially the new
1492 post-configuration update hook)
1493 - Other small bugfixes
