7 *(Released Thu, 12 May 2011)*
9 Many bug-fixes and a few new small features:
11 - Fixed a bug related to log opening failures
12 - Fixed a bug in instance listing with orphan instances
13 - Fixed a bug which prevented resetting the cluster-level node parameter
14 ``oob_program`` to the default
15 - Many fixes related to the ``cluster-merge`` tool
16 - Fixed a race condition in the lock monitor, which caused failures
17 during (at least) creation of many instances in parallel
18 - Improved output for gnt-job info
19 - Removed the quiet flag on some ssh calls which prevented debugging
21 - Improved the N+1 failure messages in cluster verify by actually
22 showing the memory values (needed and available)
23 - Increased lock attempt timeouts so that when executing long operations
24 (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire'
25 too early and thus prevent the use of the 'fair' mechanism
26 - Changed instance query data (``gnt-instance info``) to not acquire
27 locks unless needed, thus allowing its use on locked instance if only
28 static information is asked for
29 - Improved behaviour with filesystems that do not support rename on an
31 - Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which
32 kept locks on all nodes during the wipe, which is unneeded
33 - Fixed ``gnt-watcher`` handling of errors during hooks execution
34 - Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than
35 10GiB) which caused the wipe to fail right at the end in some cases
36 - Fixed master IP activation when doing master failover with no-voting
37 - Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of
38 the master node itself
39 - Fixed potential data-loss in under disk full conditions, where Ganeti
40 wouldn't check correctly the return code and would consider
41 partially-written files 'correct'
42 - Fixed bug related to multiple VGs and DRBD disk replacing
43 - Added new disk parameter ``metavg`` that allows placement of the meta
44 device for DRBD in a different volume group
45 - Fixed error handling in the node daemon when the system libc doesn't
46 have major number 6 (i.e. if ``libc.so.6`` is not the actual libc)
47 - Fixed lock release during replace-disks, which kept cluster-wide locks
48 when doing disk replaces with an iallocator script
49 - Added check for missing bridges in cluster verify
50 - Handle EPIPE errors while writing to the terminal better, so that
51 piping the output to e.g. ``less`` doesn't cause a backtrace
52 - Fixed rare case where a ^C during Luxi calls could have been
53 interpreted as server errors, instead of simply terminating
54 - Fixed a race condition in LUGroupAssignNodes (``gnt-group
56 - Added a few more parameters to the KVM hypervisor, allowing a second
57 CDROM, custom disk type for CDROMs and a floppy image
58 - Removed redundant message in instance rename when the name is given
60 - Added option to ``gnt-instance recreate-disks`` to allow creating the
61 disks on new nodes, allowing recreation when the original instance
62 nodes are completely gone
63 - Added option when converting disk templates to DRBD to skip waiting
64 for the resync, in order to make the instance available sooner
65 - Added two new variables to the OS scripts environment (containing the
67 - Made the root_path and optional parameter for the xen-pvm hypervisor,
68 to allow use of ``pvgrub`` as bootloader
69 - Changed the instance memory modifications to only check out-of-memory
70 conditions on memory increases, and turned the secondary node warnings
71 into errors (they can still be overridden via ``--force``)
72 - Fixed the handling of a corner case when the Python installation gets
73 corrupted (e.g. a bad disk) while ganeti-noded is running and we try
74 to execute a command that doesn't exist
75 - Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary
76 node of the instance returned failures during instance shutdown; this
77 adds the option ``--ignore-consistency`` to gnt-instance move
79 And as usual, various improvements to the error messages, documentation
85 *(Released Wed, 09 Mar 2011)*
87 Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
88 the RAPI users file if run twice (even with ``-dry-run``).
90 The release fixes that bug (nothing else changed).
96 *(Released Mon, 07 Mar 2011)*
98 Final 2.4.0 release. Just a few small fixes:
100 - Fixed RAPI node evacuate
101 - Fixed the kvm-ifup script
102 - Fixed internal error handling for special job cases
103 - Updated man page to specify the escaping feature for options
109 *(Released Mon, 28 Feb 2011)*
111 A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
112 that this feature wiped the disks of the wrong instance, leading to loss
117 - Fixed title of query field containing instance name
118 - Expanded the glossary in the documentation
119 - Fixed one unittest (internal issue)
125 *(Released Mon, 21 Feb 2011)*
127 A number of bug fixes plus just a couple functionality changes.
129 On the user-visible side, the ``gnt-* list`` command output has changed
130 with respect to "special" field states. The current rc1 style of display
131 can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
132 the default output mode special fields states are displayed as follows:
134 - Offline resource: ``*``
135 - Unavailable/not applicable: ``-``
136 - Data missing (RPC failure): ``?``
137 - Unknown field: ``??``
139 Another user-visible change is the addition of ``--force-join`` to
144 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
145 - Fixed regression in RAPI/instance reinstall where all parameters were
146 required (instead of optional)
147 - Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
148 - Fixed iallocator usage (offline nodes were not considered offline)
149 - Fixed ``gnt-node list`` with respect to non-vm_capable nodes
150 - Fixed hypervisor and OS parameter validation with respect to
152 - Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
154 - Fixed ``tools/listrunner`` with respect to agent-based usage
160 *(Released Fri, 4 Feb 2011)*
162 Many changes and fixes since the beta1 release. While there were some
163 internal changes, the code has been mostly stabilised for the RC
166 Note: the dumb allocator was removed in this release, as it was not kept
167 up-to-date with the IAllocator protocol changes. It is recommended to
168 use the ``hail`` command from the ganeti-htools package.
170 Note: the 2.4 and up versions of Ganeti are not compatible with the
171 0.2.x branch of ganeti-htools. You need to upgrade to
172 ganeti-htools-0.3.0 (or later).
174 Regressions fixed from 2.3
175 ~~~~~~~~~~~~~~~~~~~~~~~~~~
177 - Fixed the ``gnt-cluster verify-disks`` command

186 - Fixed corner case in KVM handling of NICs
187 - Fixed many cases of wrong handling of non-vm_capable nodes
188 - Fixed a bug where a missing instance symlink was not possible to

190 activate-disks`` does it)
191 - Fixed the volume group name as reported by ``gnt-cluster
193 - Increased timeouts for the import-export code, hopefully leading to
194 fewer aborts due network or instance timeouts

203 multi-node groups (currently it is not recommended to use this tool)
209 - Improved network configuration for the KVM hypervisor
210 - Added e1000 as a supported NIC for Xen-HVM
211 - Improved the lvmstrap tool to also be able to use partitions, as
212 opposed to full disks
213 - Improved speed of disk wiping (the cluster parameter
214 ``prealloc_wipe_disks``, so that it has a low impact on the total time
215 of instance creations
216 - Added documentation for the OS parameters
217 - Changed ``gnt-instance deactivate-disks`` so that it can work if the
218 hypervisor is not responding
219 - Added display of blacklisted and hidden OS information in
221 - Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
222 NIC and node parameters, which might create problems with currently
223 invalid (but undetected) configuration files, but prevents validation
224 failures when unrelated parameters are modified
225 - Changed cluster initialisation to wait for the master daemon to become
227 - Expanded the RAPI interface:
229 - Added config redistribution resource
230 - Added activation/deactivation of instance disks
231 - Added export of console information
233 - Implemented log file reopening on SIGHUP, which allows using
234 logrotate(8) for the Ganeti log files
235 - Added a basic OOB helper script as an example
241 *(Released Fri, 14 Jan 2011)*
246 - Fixed timezone issues when formatting timestamps

264 - ``gnt-instance list-fields``
266 - Updated documentation and man pages
271 - Moved ``rapi_users`` file into separate directory, now named
272 ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
274 - Added new tool for running commands on many machines,
275 ``tools/ganeti-listrunner``
276 - Implemented more verbose result in ``OpInstanceConsole`` opcode, also

280 - Added support for non-partitioned md disks in ``lvmstrap``
281 - Added script to gracefully power off KVM instances
282 - Split ``utils`` module into smaller parts
283 - Changed query operations to return more detailed information, e.g.
284 whether an information is unavailable due to an offline node. To use
285 this new functionality, the LUXI call ``Query`` must be used. Field
286 information is now stored by the master daemon and can be retrieved
287 using ``QueryFields``. Instances, nodes and groups can also be queried
288 using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
289 exposed via RAPI). The following commands make use of this
290 infrastructure change:
293 - ``gnt-group list-fields``
295 - ``gnt-node list-fields``
296 - ``gnt-instance list``
297 - ``gnt-instance list-fields``

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

511 - Fixed dry-run behaviour with many commands
512 - Support ``ssh-agent`` again when adding nodes
513 - Many additional bugfixes
519 *(Released Fri, 30 Jul 2010)*
521 Important change: the internal RPC mechanism between Ganeti nodes has
522 changed from using a home-grown http library (based on the Python base
523 libraries) to use the PycURL library. This requires that PycURL is
524 installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
525 against GnuTLS by default. cURL's support for GnuTLS had known issues
526 before cURL 7.21.0 and we recommend using the latest cURL release or
527 linking against OpenSSL. Most other distributions already link PycURL
528 and cURL against OpenSSL. The command::
530 python -c 'import pycurl; print pycurl.version'
532 can be used to determine the libraries PycURL and cURL are linked
535 Other significant changes:
537 - Rewrote much of the internals of the job queue, in order to achieve
538 better parallelism; this decouples job query operations from the job
539 processing, and it should allow much nicer behaviour of the master
540 daemon under load, and it also has uncovered some long-standing bugs
541 related to the job serialisation (now fixed)
542 - Added a default iallocator setting to the cluster parameters,
543 eliminating the need to always pass nodes or an iallocator for
544 operations that require selection of new node(s)
545 - Added experimental support for the LXC virtualization method
546 - Added support for OS parameters, which allows the installation of
547 instances to pass parameter to OS scripts in order to customise the
549 - Added a hypervisor parameter controlling the migration type (live or
550 non-live), since hypervisors have various levels of reliability; this
551 has renamed the 'live' parameter to 'mode'
552 - Added a cluster parameter ``reserved_lvs`` that denotes reserved
553 logical volumes, meaning that cluster verify will ignore them and not
554 flag their presence as errors
555 - The watcher will now reset the error count for failed instances after
556 8 hours, thus allowing self-healing if the problem that caused the
557 instances to be down/fail to start has cleared in the meantime
558 - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
559 check for, and warn, if the drbd module parameter ``usermode_helper``
560 is not consistent with the cluster-wide setting; this is needed to
561 make diagnose easier of failed drbd creations
562 - Started adding base IPv6 support, but this is not yet
563 enabled/available for use
564 - Rename operations (cluster, instance) will now return the new name,
565 which is especially useful if a short name was passed in
566 - Added support for instance migration in RAPI
567 - Added a tool to pre-configure nodes for the SSH setup, before joining
568 them to the cluster; this will allow in the future a simplified model
569 for node joining (but not yet fully enabled in 2.2); this needs the
570 paramiko python library
571 - Fixed handling of name-resolving errors
572 - Fixed consistency of job results on the error path
573 - Fixed master-failover race condition when executed multiple times in
575 - Fixed many bugs related to the job queue (mostly introduced during the
576 2.2 development cycle, so not all are impacting 2.1)
577 - Fixed instance migration with missing disk symlinks
578 - Fixed handling of unknown jobs in ``gnt-job archive``
579 - And many other small fixes/improvements
583 - Enhanced both the unittest and the QA coverage
584 - Switched the opcode validation to a generic model, and extended the
585 validation to all opcode parameters
586 - Changed more parts of the code that write shell scripts to use the
588 - Switched the master daemon to use the asyncore library for the Luxi
595 *(Released Thu, 17 Jun 2010)*
597 - Added tool (``move-instance``) and infrastructure to move instances
598 between separate clusters (see :doc:`separate documentation
599 <move-instance>` and :doc:`design document <design-2.2>`)
600 - Added per-request RPC timeout
601 - RAPI now requires a Content-Type header for requests with a body (e.g.
602 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
603 :rfc:`2616` (HTTP/1.1), section 7.2.1)
604 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
606 - Implemented initial support for running Ganeti daemons as separate
607 users, see configure-time flags ``--with-user-prefix`` and
608 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
610 - Instances can be removed after export (``gnt-backup export
612 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
613 key (instead of 1024 bit)
614 - Added new cluster configuration file for cluster domain secret
615 - Import/export now use SSL instead of SSH
616 - Added support for showing estimated time when exporting an instance,
617 see the ``ganeti-os-interface(7)`` manpage and look for
624 *(Released Tue, 16 Nov 2010)*
626 Some more bugfixes. Unless critical bugs occur, this will be the last
629 - Fix case of MAC special-values
630 - Fix mac checker regex
631 - backend: Fix typo causing "out of range" error
632 - Add missing --units in gnt-instance list man page
638 *(Released Tue, 24 Aug 2010)*
641 - Don't ignore secondary node silently on non-mirrored disk templates
643 - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
644 - Fix usb_mouse parameter breaking with vnc_console (issue 109)
645 - Properly document the usb_mouse parameter
646 - Fix path in ganeti-rapi(8) (issue 116)
647 - Adjust error message when the ganeti user's .ssh directory is
649 - Add same-node-check when changing the disk template to drbd
655 *(Released Fri, 16 Jul 2010)*
658 - Add an option to only select some reboot types during qa/burnin.
659 (on some hypervisors consequent reboots are not supported)
660 - Fix infrequent race condition in master failover. Sometimes the old
661 master ip address would be still detected as up for a short time
662 after it was removed, causing failover to fail.
663 - Decrease mlockall warnings when the ctypes module is missing. On
664 Python 2.4 we support running even if no ctypes module is installed,
665 but we were too verbose about this issue.
666 - Fix building on old distributions, on which man doesn't have a
668 - Fix RAPI not to ignore the MAC address on instance creation
669 - Implement the old instance creation format in the RAPI client.
675 *(Released Thu, 01 Jul 2010)*
677 A small bugfix release:
678 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
679 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
680 a non-existing option
681 - Fix instance create: the --force-variant option was ignored
682 - Improve pylint 0.21 compatibility and warnings with Python 2.6
683 - Fix modify node storage with non-FQDN arguments
684 - Fix RAPI client to authenticate under Python 2.6 when used
685 for more than 5 requests needing authentication
686 - Fix gnt-instance modify -t (storage) giving a wrong error message
687 when converting a non-shutdown drbd instance to plain
693 *(Released Fri, 18 Jun 2010)*
695 A small bugfix release:
697 - Fix live migration of KVM instances started with older Ganeti
698 versions which had fewer hypervisor parameters
699 - Fix gnt-instance grow-disk on down instances
700 - Fix an error-reporting bug during instance migration
701 - Better checking of the ``--net`` and ``--disk`` values, to avoid
702 silently ignoring broken ones
703 - Fix an RPC error reporting bug affecting, for example, RAPI client
705 - Fix bug triggered by different API version os-es on different nodes
706 - Fix a bug in instance startup with custom hvparams: OS level
707 parameters would fail to be applied.
708 - Fix the RAPI client under Python 2.6 (but more work is needed to
709 make it work completely well with OpenSSL)
710 - Fix handling of errors when resolving names from DNS
716 *(Released Thu, 3 Jun 2010)*
718 A medium sized development cycle. Some new features, and some
719 fixes/small improvements/cleanups.
724 The node deamon now tries to mlock itself into memory, unless the
725 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
726 its logs, and falls back to console logging. This allows emergency
727 features such as ``gnt-node powercycle`` to work even in the event of a
728 broken node disk (tested offlining the disk hosting the node's
729 filesystem and dropping its memory caches; don't try this at home)
731 KVM: add vhost-net acceleration support. It can be tested with a new
732 enough version of the kernel and of qemu-kvm.
734 KVM: Add instance chrooting feature. If you use privilege dropping for
735 your VMs you can also now force them to chroot to an empty directory,
736 before starting the emulated guest.
738 KVM: Add maximum migration bandwith and maximum downtime tweaking
739 support (requires a new-enough version of qemu-kvm).
741 Cluster verify will now warn if the master node doesn't have the master
744 Add a new (incompatible) instance creation request format to RAPI which
745 supports all parameters (previously only a subset was supported, and it
746 wasn't possible to extend the old format to accomodate all the new
747 features. The old format is still supported, and a client can check for
748 this feature, before using it, by checking for its presence in the
749 ``features`` RAPI resource.
751 Now with ancient latin support. Try it passing the ``--roman`` option to
752 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
753 (requires the python-roman module to be installed, in order to work).
758 As usual many internal code refactorings, documentation updates, and
761 - Lots of improvements and cleanups to the experimental Remote API
762 (RAPI) client library.
763 - A new unit test suite for the core daemon libraries.
764 - A fix to creating missing directories makes sure the umask is not
765 applied anymore. This enforces the same directory permissions
767 - Better handling terminating daemons with ctrl+c (used when running
768 them in debugging mode).
769 - Fix a race condition in live migrating a KVM instance, when stat()
770 on the old proc status file returned EINVAL, which is an unexpected
772 - Fixed manpage checking with newer man and utf-8 charachters. But now
773 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
779 *(Released Fri, 7 May 2010)*
781 Fix a bug which prevented untagged KVM instances from starting.
787 *(Released Fri, 7 May 2010)*
789 Another release with a long development cycle, during which many
790 different features were added.
795 The KVM hypervisor now can run the individual instances as non-root, to
796 reduce the impact of a VM being hijacked due to bugs in the
797 hypervisor. It is possible to run all instances as a single (non-root)
798 user, to manually specify a user for each instance, or to dynamically
799 allocate a user out of a cluster-wide pool to each instance, with the
800 guarantee that no two instances will run under the same user ID on any
803 An experimental RAPI client library, that can be used standalone
804 (without the other Ganeti libraries), is provided in the source tree as
805 ``lib/rapi/client.py``. Note this client might change its interface in
806 the future, as we iterate on its capabilities.
808 A new command, ``gnt-cluster renew-crypto`` has been added to easily
809 replace the cluster's certificates and crypto keys. This might help in
810 case they have been compromised, or have simply expired.
812 A new disk option for instance creation has been added that allows one
813 to "adopt" currently existing logical volumes, with data
814 preservation. This should allow easier migration to Ganeti from
815 unmanaged (or managed via other software) instances.
817 Another disk improvement is the possibility to convert between redundant
818 (DRBD) and plain (LVM) disk configuration for an instance. This should
819 allow better scalability (starting with one node and growing the
820 cluster, or shrinking a two-node cluster to one node).
822 A new feature that could help with automated node failovers has been
823 implemented: if a node sees itself as offline (by querying the master
824 candidates), it will try to shutdown (hard) all instances and any active
825 DRBD devices. This reduces the risk of duplicate instances if an
826 external script automatically failovers the instances on such nodes. To
827 enable this, the cluster parameter ``maintain_node_health`` should be
828 enabled; in the future this option (per the name) will enable other
829 automatic maintenance features.
831 Instance export/import now will reuse the original instance
832 specifications for all parameters; that means exporting an instance,
833 deleting it and the importing it back should give an almost identical
834 instance. Note that the default import behaviour has changed from
835 before, where it created only one NIC; now it recreates the original
838 Cluster verify has added a few new checks: SSL certificates validity,
839 /etc/hosts consistency across the cluster, etc.
844 As usual, many internal changes were done, documentation fixes,
847 - Fixed cluster initialization with disabled cluster storage (regression
849 - File-based storage supports growing the disks
850 - Fixed behaviour of node role changes
851 - Fixed cluster verify for some corner cases, plus a general rewrite of
852 cluster verify to allow future extension with more checks
853 - Fixed log spamming by watcher and node daemon (regression introduced
855 - Fixed possible validation issues when changing the list of enabled
857 - Fixed cleanup of /etc/hosts during node removal
858 - Fixed RAPI response for invalid methods
859 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
860 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
861 from ide disks, etc.)
862 - Allow OS changes without re-installation (to record a changed OS
863 outside of Ganeti, or to allow OS renames)
864 - Allow instance creation without OS installation (useful for example if
865 the OS will be installed manually, or restored from a backup not in
867 - Implemented option to make cluster ``copyfile`` use the replication
869 - Added list of enabled hypervisors to ssconf (possibly useful for
871 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
873 - A partial form of node re-IP is possible via node readd, which now
874 allows changed node primary IP
875 - Command line utilities now show an informational message if the job is
877 - The logs of the master daemon now show the PID/UID/GID of the
884 *(Released Fri, 12 Mar 2010)*
886 During the 2.1.0 long release candidate cycle, a lot of improvements and
887 changes have accumulated with were released later as 2.1.1.
892 The node evacuate command (``gnt-node evacuate``) was significantly
893 rewritten, and as such the IAllocator protocol was changed - a new
894 request type has been added. This unfortunate change during a stable
895 series is designed to improve performance of node evacuations; on
896 clusters with more than about five nodes and which are well-balanced,
897 evacuation should proceed in parallel for all instances of the node
898 being evacuated. As such, any existing IAllocator scripts need to be
899 updated, otherwise the above command will fail due to the unknown
900 request. The provided "dumb" allocator has not been updated; but the
901 ganeti-htools package supports the new protocol since version 0.2.4.
903 Another important change is increased validation of node and instance
904 names. This might create problems in special cases, if invalid host
905 names are being used.
907 Also, a new layer of hypervisor parameters has been added, that sits at
908 OS level between the cluster defaults and the instance ones. This allows
909 customisation of virtualization parameters depending on the installed
910 OS. For example instances with OS 'X' may have a different KVM kernel
911 (or any other parameter) than the cluster defaults. This is intended to
912 help managing a multiple OSes on the same cluster, without manual
913 modification of each instance's parameters.
915 A tool for merging clusters, ``cluster-merge``, has been added in the
921 - Improved the int/float conversions that should make the code more
922 robust in face of errors from the node daemons
923 - Fixed the remove node code in case of internal configuration errors
924 - Fixed the node daemon behaviour in face of inconsistent queue
925 directory (e.g. read-only file-system where we can't open the files
927 - Fixed the behaviour of gnt-node modify for master candidate demotion;
928 now it either aborts cleanly or, if given the new "auto_promote"
929 parameter, will automatically promote other nodes as needed
930 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
931 completely prevent Ganeti from working
932 - Fixed bug for instance export when not all disks were successfully
934 - Fixed behaviour of node add when the new node is slow in starting up
936 - Fixed handling of signals in the LUXI client, which should improve
937 behaviour of command-line scripts
938 - Added checks for invalid node/instance names in the configuration (now
939 flagged during cluster verify)
940 - Fixed watcher behaviour for disk activation errors
941 - Fixed two potentially endless loops in http library, which led to the
942 RAPI daemon hanging and consuming 100% CPU in some cases
943 - Fixed bug in RAPI daemon related to hashed passwords
944 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
946 - Enhanced compatibility with non-Debian OSes, but not using absolute
947 path in some commands and allowing customisation of the ssh
948 configuration directory
949 - Fixed possible future issue with new Python versions by abiding to the
950 proper use of ``__slots__`` attribute on classes
951 - Added checks that should prevent directory traversal attacks
952 - Many documentation fixes based on feedback from users
957 - Added an "early_release" more for instance replace disks and node
958 evacuate, where we release locks earlier and thus allow higher
959 parallelism within the cluster
960 - Added watcher hooks, intended to allow the watcher to restart other
961 daemons (e.g. from the ganeti-nbma project), but they can be used of
962 course for any other purpose
963 - Added a compile-time disable for DRBD barriers, to increase
964 performance if the administrator trusts the power supply or the
965 storage system to not lose writes
966 - Added the option of using syslog for logging instead of, or in
967 addition to, Ganeti's own log files
968 - Removed boot restriction for paravirtual NICs for KVM, recent versions
969 can indeed boot from a paravirtual NIC
970 - Added a generic debug level for many operations; while this is not
971 used widely yet, it allows one to pass the debug value all the way to
973 - Enhanced the hooks environment for instance moves (failovers,
974 migrations) where the primary/secondary nodes changed during the
975 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
976 - Enhanced data validations for many user-supplied values; one important
977 item is the restrictions imposed on instance and node names, which
978 might reject some (invalid) host names
979 - Add a configure-time option to disable file-based storage, if it's not
980 needed; this allows greater security separation between the master
981 node and the other nodes from the point of view of the inter-node RPC
983 - Added user notification in interactive tools if job is waiting in the
984 job queue or trying to acquire locks
985 - Added log messages when a job is waiting for locks
986 - Added filtering by node tags in instance operations which admit
987 multiple instances (start, stop, reboot, reinstall)
988 - Added a new tool for cluster mergers, ``cluster-merge``
989 - Parameters from command line which are of the form ``a=b,c=d`` can now
990 use backslash escapes to pass in values which contain commas,
991 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
993 - For KVM, the instance name is the first parameter passed to KVM, so
994 that it's more visible in the process list
1000 *(Released Tue, 2 Mar 2010)*
1002 Ganeti 2.1 brings many improvements with it. Major changes:
1004 - Added infrastructure to ease automated disk repairs
1005 - Added new daemon to export configuration data in a cheaper way than
1006 using the remote API
1007 - Instance NICs can now be routed instead of being associated with a
1009 - Improved job locking logic to reduce impact of jobs acquiring multiple
1010 locks waiting for other long-running jobs
1012 In-depth implementation details can be found in the Ganeti 2.1 design
1018 - Added chroot hypervisor
1019 - Added more options to xen-hvm hypervisor (``kernel_path`` and
1021 - Added more options to xen-pvm hypervisor (``use_bootloader``,
1022 ``bootloader_path`` and ``bootloader_args``)
1023 - Added the ``use_localtime`` option for the xen-hvm and kvm
1024 hypervisors, and the default value for this has changed to false (in
1025 2.0 xen-hvm always enabled it)
1026 - Added luxi call to submit multiple jobs in one go
1027 - Added cluster initialization option to not modify ``/etc/hosts``
1029 - Added network interface parameters
1030 - Added dry run mode to some LUs
1031 - Added RAPI resources:

1035 - ``/2/nodes/[node_name]/evacuate``
1036 - ``/2/nodes/[node_name]/migrate``
1037 - ``/2/nodes/[node_name]/role``
1038 - ``/2/nodes/[node_name]/storage``
1039 - ``/2/nodes/[node_name]/storage/modify``
1040 - ``/2/nodes/[node_name]/storage/repair``
1042 - Added OpCodes to evacuate or migrate all instances on a node
1043 - Added new command to list storage elements on nodes (``gnt-node
1044 list-storage``) and modify them (``gnt-node modify-storage``)
1045 - Added new ssconf files with master candidate IP address
1046 (``ssconf_master_candidates_ips``), node primary IP address
1047 (``ssconf_node_primary_ips``) and node secondary IP address
1048 (``ssconf_node_secondary_ips``)
1049 - Added ``ganeti-confd`` and a client library to query the Ganeti
1050 configuration via UDP
1051 - Added ability to run hooks after cluster initialization and before
1053 - Added automatic mode for disk replace (``gnt-instance replace-disks
1055 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
1056 after catastrophic data-loss
1057 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume
1059 - Added ``gnt-instance move`` command to move instances

1061 - Added ``gnt-node powercycle`` command to powercycle nodes
1062 - Added new job status field ``lock_status``
1063 - Added parseable error codes to cluster verification (``gnt-cluster
1064 verify --error-codes``) and made output less verbose (use
1065 ``--verbose`` to restore previous behaviour)
1066 - Added UUIDs to the main config entities (cluster, nodes, instances)
1067 - Added support for OS variants
1068 - Added support for hashed passwords in the Ganeti remote API users file
1070 - Added option to specify maximum timeout on instance shutdown
1071 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
1072 - Added new helper script to start and stop Ganeti daemons
1073 (``daemon-util``), with the intent to reduce the work necessary to
1074 adjust Ganeti for non-Debian distributions and to start/stop daemons
1076 - Added more unittests
1077 - Fixed critical bug in ganeti-masterd startup
1078 - Removed the configure-time ``kvm-migration-port`` parameter, this is
1079 now customisable at the cluster level for both the KVM and Xen
1080 hypervisors using the new ``migration_port`` parameter
1081 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
1082 reinstalling an instance
1083 - Allowed ``@`` in tag names
1084 - Migrated to Sphinx (http://sphinx.pocoo.org/) for documentation
1085 - Many documentation updates

1104 - Fix a string formatting bug
1105 - Improve safety of the code in some error paths
1106 - Improve data validation in the master of values returned from nodes
1112 *(Released Thu, 17 Dec 2009)*
1114 - Fix security issue due to missing validation of iallocator names; this
1115 allows local and remote execution of arbitrary executables
1116 - Fix failure of gnt-node list during instance removal
1117 - Ship the RAPI documentation in the archive
1123 *(Released Wed, 30 Sep 2009)*
1125 - Fixed many wrong messages
1126 - Fixed a few bugs related to the locking library
1127 - Fixed MAC checking at instance creation time
1128 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1129 - Fixed a few issues related to signal handling in both daemons and
1131 - Fixed the example startup script provided
1132 - Fixed insserv dependencies in the example startup script (patch from
1134 - Fixed handling of drained nodes in the iallocator framework
1135 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1137 - Fixed error related to invalid job IDs in job polling
1138 - Fixed job/opcode persistence on unclean master shutdown
1139 - Fixed handling of partial job processing after unclean master
1141 - Fixed error reporting from LUs, previously all errors were converted
1142 into execution errors
1143 - Fixed error reporting from burnin
1144 - Decreased significantly the memory usage of the job queue
1145 - Optimised slightly multi-job submission
1146 - Optimised slightly opcode loading
1147 - Backported the multi-job submit framework from the development
1148 branch; multi-instance start and stop should be faster
1149 - Added script to clean archived jobs after 21 days; this will reduce
1150 the size of the queue directory
1151 - Added some extra checks in disk size tracking
1152 - Added an example ethers hook script
1153 - Added a cluster parameter that prevents Ganeti from modifying of
1155 - Added more node information to RAPI responses
1156 - Added a ``gnt-job watch`` command that allows following the ouput of a
1158 - Added a bind-address option to ganeti-rapi
1159 - Added more checks to the configuration verify
1160 - Enhanced the burnin script such that some operations can be retried
1162 - Converted instance reinstall to multi-instance model
1168 *(Released Fri, 7 Aug 2009)*
1170 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1171 to allow using the pre-2.0.2 behaviour in activation, if any existing
1172 instances have mismatched disk sizes in the configuration
1173 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1174 any configuration mismatches for disk sizes
1175 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1176 failover to work on two-node clusters
1177 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1179 - Fixed detection of OS script errors in ``gnt-backup export``
1180 - Fixed exit code of ``gnt-backup export``
1186 *(Released Fri, 17 Jul 2009)*
1188 - Added experimental support for stripped logical volumes; this should
1189 enhance performance but comes with a higher complexity in the block
1190 device handling; stripping is only enabled when passing
1191 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1192 affected even in the non-stripped mode
1193 - Improved resiliency against transient failures at the end of DRBD
1194 resyncs, and in general of DRBD resync checks
1195 - Fixed a couple of issues with exports and snapshot errors
1196 - Fixed a couple of issues in instance listing
1197 - Added display of the disk size in ``gnt-instance info``
1198 - Fixed checking for valid OSes in instance creation
1199 - Fixed handling of the "vcpus" parameter in instance listing and in
1200 general of invalid parameters
1201 - Fixed http server library, and thus RAPI, to handle invalid
1202 username/password combinations correctly; this means that now they
1203 report unauthorized for queries too, not only for modifications,
1204 allowing earlier detect of configuration problems
1205 - Added a new "role" node list field, equivalent to the master/master
1206 candidate/drained/offline flags combinations
1207 - Fixed cluster modify and changes of candidate pool size
1208 - Fixed cluster verify error messages for wrong files on regular nodes
1209 - Fixed a couple of issues with node demotion from master candidate role
1210 - Fixed node readd issues
1211 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1212 - Added a new ``--no-voting`` option for masterfailover to fix failover
1213 on two-nodes clusters when the former master node is unreachable
1214 - Added instance reinstall over RAPI
1220 *(Released Tue, 16 Jun 2009)*
1222 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1223 allow re-adding the start in single-user option (regression from 1.2)
1224 - the watcher writes the instance status to a file, to allow monitoring
1225 to report the instance status (from the master) based on cached
1226 results of the watcher's queries; while this can get stale if the
1227 watcher is being locked due to other work on the cluster, this is
1228 still an improvement
1229 - the watcher now also restarts the node daemon and the rapi daemon if
1231 - fixed the watcher to handle full and drained queue cases
1232 - hooks export more instance data in the environment, which helps if
1233 hook scripts need to take action based on the instance's properties
1234 (no longer need to query back into ganeti)
1235 - instance failovers when the instance is stopped do not check for free
1236 RAM, so that failing over a stopped instance is possible in low memory
1238 - rapi uses queries for tags instead of jobs (for less job traffic), and
1239 for cluster tags it won't talk to masterd at all but read them from
1241 - a couple of error handling fixes in RAPI
1242 - drbd handling: improved the error handling of inconsistent disks after
1243 resync to reduce the frequency of "there are some degraded disks for
1244 this instance" messages
1245 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1246 error handling path called a wrong function name)
1252 *(Released Wed, 27 May 2009)*
1254 - no changes from rc5
1257 Version 2.0 release candidate 5
1258 -------------------------------
1260 *(Released Wed, 20 May 2009)*
1262 - fix a couple of bugs (validation, argument checks)
1263 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1264 - some small improvements to RAPI and IAllocator
1265 - make watcher automatically start the master daemon if down
1268 Version 2.0 release candidate 4
1269 -------------------------------
1271 *(Released Mon, 27 Apr 2009)*
1273 - change the OS list to not require locks; this helps with big clusters
1274 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1275 volume group is broken
1276 - ``gnt-instance info``, without any arguments, doesn't run for all
1277 instances anymore; either pass ``--all`` or pass the desired
1278 instances; this helps against mistakes on big clusters where listing
1279 the information for all instances takes a long time
1280 - miscellaneous doc and man pages fixes
1283 Version 2.0 release candidate 3
1284 -------------------------------
1286 *(Released Wed, 8 Apr 2009)*
1288 - Change the internal locking model of some ``gnt-node`` commands, in
1289 order to reduce contention (and blocking of master daemon) when
1290 batching many creation/reinstall jobs
1291 - Fixes to Xen soft reboot
1292 - No longer build documentation at build time, instead distribute it in
1293 the archive, in order to reduce the need for the whole docbook/rst
1297 Version 2.0 release candidate 2
1298 -------------------------------
1300 *(Released Fri, 27 Mar 2009)*
1302 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1303 - Fix watcher startup sequence, improves the behaviour of busy clusters
1304 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1305 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1306 bind address and other places
1307 - Some documentation fixes and updates
1310 Version 2.0 release candidate 1
1311 -------------------------------
1313 *(Released Mon, 2 Mar 2009)*
1315 - More documentation updates, now all docs should be more-or-less
1317 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1319 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1321 - Fix an issue related to $libdir/run/ganeti and cluster creation
1327 *(Released Thu, 19 Feb 2009)*
1329 - Xen PVM and KVM have switched the default value for the instance root
1330 disk to the first partition on the first drive, instead of the whole
1331 drive; this means that the OS installation scripts must be changed
1333 - Man pages have been updated
1334 - RAPI has been switched by default to HTTPS, and the exported functions
1335 should all work correctly
1336 - RAPI v1 has been removed
1337 - Many improvements to the KVM hypervisor
1338 - Block device errors are now better reported
1339 - Many other bugfixes and small improvements
1345 *(Released Mon, 26 Jan 2009)*
1347 - Version 2 is a general rewrite of the code and therefore the
1348 differences are too many to list, see the design document for 2.0 in
1349 the ``doc/`` subdirectory for more details
1350 - In this beta version there is not yet a migration path from 1.2 (there
1351 will be one in the final 2.0 release)
1352 - A few significant changes are:
1354 - all commands are executed by a daemon (``ganeti-masterd``) and the
1355 various ``gnt-*`` commands are just front-ends to it
1356 - all the commands are entered into, and executed from a job queue,
1357 see the ``gnt-job(8)`` manpage
1358 - the RAPI daemon supports read-write operations, secured by basic
1359 HTTP authentication on top of HTTPS
1360 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1361 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1362 to migrate to DRBD 8 first while still running Ganeti 1.2)
1363 - DRBD devices are using statically allocated minor numbers, which
1364 will be assigned to existing instances during the migration process
1365 - there is support for both Xen PVM and Xen HVM instances running on
1367 - KVM virtualization is supported too
1368 - file-based storage has been implemented, which means that it is
1369 possible to run the cluster without LVM and DRBD storage, for
1370 example using a shared filesystem exported from shared storage (and
1371 still have live migration)
1377 *(Released Tue, 13 Jan 2009)*
1379 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1380 - Reuse the old instance mac address by default on instance import, if
1381 the instance name is the same.
1382 - Handle situations in which the node info rpc returns incomplete
1384 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1385 - Improved version of batcher:
1387 - state file support
1388 - instance mac address support
1389 - support for HVM clusters/instances
1391 - Add an option to show the number of cpu sockets and nodes in
1393 - Support OSes that handle more than one version of the OS api (but do
1394 not change the current API in any other way)
1395 - Fix ``gnt-node migrate``
1396 - ``gnt-debug`` man page
1397 - Fixes various more typos and small issues
1398 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1404 *(Released Wed, 24 Sep 2008)*
1406 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1407 type of disk exported to fully virtualized instances.
1408 - provide access to the serial console of HVM instances
1409 - instance auto_balance flag, set by default. If turned off it will
1410 avoid warnings on cluster verify if there is not enough memory to fail
1411 over an instance. in the future it will prevent automatically failing
1412 it over when we will support that.
1413 - batcher tool for instance creation, see ``tools/README.batcher``
1414 - ``gnt-instance reinstall --select-os`` to interactively select a new
1415 operating system when reinstalling an instance.
1416 - when changing the memory amount on instance modify a check has been
1417 added that the instance will be able to start. also warnings are
1418 emitted if the instance will not be able to fail over, if auto_balance
1420 - documentation fixes
1421 - sync fields between ``gnt-instance list/modify/add/import``
1422 - fix a race condition in drbd when the sync speed was set after giving
1423 the device a remote peer.
1429 *(Released Tue, 22 Jul 2008)*
1431 - note: the allowed size and number of tags per object were reduced
1432 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1433 - fixed twisted 8.x compatibility
1434 - fixed ``gnt-instance replace-disks`` with iallocator
1435 - add TCP keepalives on twisted connections to detect restarted nodes
1436 - disk increase support, see ``gnt-instance grow-disk``
1437 - implement bulk node/instance query for RAPI
1438 - add tags in node/instance listing (optional)
1439 - experimental migration (and live migration) support, read the man page
1440 for ``gnt-instance migrate``
1441 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1442 has some small improvements in handling its state file
1448 *(Released Fri, 13 Jun 2008)*
1450 - Experimental readonly, REST-based remote API implementation;
1451 automatically started on master node, TCP port 5080, if enabled by
1452 ``--enable-rapi`` parameter to configure script.
1453 - Instance allocator support. Add and import instance accept a
1454 ``--iallocator`` parameter, and call that instance allocator to decide
1455 which node to use for the instance. The iallocator document describes
1456 what's expected from an allocator script.
1457 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1458 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1459 node is lost there is still enough memory to fail over the instances
1461 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1462 ``gnt-cluster verify``, to check for site-specific compliance. All the
1463 hooks will run, and their output, if any, will be displayed. Any
1464 failing hook will make the verification return an error value.
1465 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1466 primary and secondary interfaces
1467 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1468 that is still declared as part of the cluster and has failed.
1469 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1470 specifying output fields, that just adds the chosen fields to the
1472 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1473 export from the filesystem.
1474 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1475 have been added. Using them you can enable/disable acpi and pae
1476 support, and specify a path for a cd image to be exported to the
1477 instance. These parameters as the name suggest only work on HVM
1479 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1480 PAE support will be set to the previously hardcoded values, but the
1481 (previously hardcoded) path to the CDROM ISO image will be unset and
1482 if required, needs to be set manually with ``gnt-instance modify``
1484 - The address to which an instance's VNC console is bound is now
1485 selectable per-instance, rather than being cluster wide. Of course
1486 this only applies to instances controlled via VNC, so currently just
1487 applies to HVM clusters.
1493 *(Released Mon, 18 Feb 2008)*
1495 - more tweaks to the disk activation code (especially helpful for DRBD)
1496 - change the default ``gnt-instance list`` output format, now there is
1497 one combined status field (see the manpage for the exact values this
1499 - some more fixes for the mac export to hooks change
1500 - make Ganeti not break with DRBD 8.2.x (which changed the version
1501 format in ``/proc/drbd``) (issue 24)
1502 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1503 template, allowing migration from DRBD0.7+MD to DRBD8
1509 *(Released Wed, 30 Jan 2008)*
1511 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1513 - add command aliases infrastructure and a few aliases
1514 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1515 man pages and the ``--help`` option of ``gnt-node
1516 list``/``gnt-instance list``
1517 - fix ``gnt-backup list`` with down nodes (issue 21)
1518 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1519 - fix the dist archive and add a check for including svn/git files in
1521 - some developer-related changes: improve the burnin and the QA suite,
1522 add an upload script for testing during development
1528 *(Released Wed, 16 Jan 2008)*
1530 - experimental HVM support, read the install document, section
1531 "Initializing the cluster"
1532 - allow for the PVM hypervisor per-instance kernel and initrd paths
1533 - add a new command ``gnt-cluster verify-disks`` which uses a new
1534 algorithm to improve the reconnection of the DRBD pairs if the device
1535 on the secondary node has gone away
1536 - make logical volume code auto-activate LVs at disk activation time
1537 - slightly improve the speed of activating disks
1538 - allow specification of the MAC address at instance creation time, and
1539 changing it later via ``gnt-instance modify``
1540 - fix handling of external commands that generate lots of output on
1542 - update documentation with regard to minimum version of DRBD8 supported
1548 *(Released Tue, 4 Dec 2007)*
1550 - Log the ``xm create`` output to the node daemon log on failure (to
1551 help diagnosing the error)
1552 - In debug mode, log all external commands output if failed to the logs
1553 - Change parsing of lvm commands to ignore stderr
1559 *(Released Wed, 28 Nov 2007)*
1561 - Another round of updates to the DRBD 8 code to deal with more failures
1562 in the replace secondary node operation
1563 - Some more logging of failures in disk operations (lvm, drbd)
1564 - A few documentation updates
1571 *(Released Tue, 13 Nov 2007)*
1573 - Change configuration file format from Python's Pickle to JSON.
1574 Upgrading is possible using the cfgupgrade utility.
1575 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1576 faster replace disks and is more stable (DRBD 8 has many improvements
1577 compared to DRBD 0.7)
1578 - Added command line tags support (see man pages for ``gnt-instance``,
1579 ``gnt-node``, ``gnt-cluster``)
1580 - Added instance rename support
1581 - Added multi-instance startup/shutdown
1582 - Added cluster rename support
1583 - Added ``gnt-node evacuate`` to simplify some node operations
1584 - Added instance reboot operation that can speedup reboot as compared to
1586 - Soften the requirement that hostnames are in FQDN format
1587 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
1589 - Removed dependency on debian's patched fping that uses the
1590 non-standard ``-S`` option
1591 - Now the OS definitions are searched for in multiple, configurable
1592 paths (easier for distros to package)
1593 - Some changes to the hooks infrastructure (especially the new
1594 post-configuration update hook)
1595 - Other small bugfixes
