7 *(Released Fri, 16 Jul 2010)*
10 - Add an option to only select some reboot types during qa/burnin.
11 (on some hypervisors consequent reboots are not supported)
12 - Fix infrequent race condition in master failover. Sometimes the old
13 master ip address would be still detected as up for a short time
14 after it was removed, causing failover to fail.
15 - Decrease mlockall warnings when the ctypes module is missing. On
16 Python 2.4 we support running even if no ctypes module is installed,
17 but we were too verbose about this issue.
18 - Fix building on old distributions, on which man doesn't have a
20 - Fix RAPI not to ignore the MAC address on instance creation
21 - Implement the old instance creation format in the RAPI client.
27 *(Released Thu, 01 Jul 2010)*
29 A small bugfix release:
30 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
31 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
33 - Fix instance create: the --force-variant option was ignored
34 - Improve pylint 0.21 compatibility and warnings with Python 2.6
35 - Fix modify node storage with non-FQDN arguments
36 - Fix RAPI client to authenticate under Python 2.6 when used
37 for more than 5 requests needing authentication
38 - Fix gnt-instance modify -t (storage) giving a wrong error message
39 when converting a non-shutdown drbd instance to plain
45 *(Released Fri, 18 Jun 2010)*
47 A small bugfix release:
49 - Fix live migration of KVM instances started with older Ganeti
50 versions which had fewer hypervisor parameters
51 - Fix gnt-instance grow-disk on down instances
52 - Fix an error-reporting bug during instance migration
53 - Better checking of the ``--net`` and ``--disk`` values, to avoid
54 silently ignoring broken ones
55 - Fix an RPC error reporting bug affecting, for example, RAPI client
57 - Fix bug triggered by different API version os-es on different nodes
58 - Fix a bug in instance startup with custom hvparams: OS level
59 parameters would fail to be applied.
60 - Fix the RAPI client under Python 2.6 (but more work is needed to
61 make it work completely well with OpenSSL)
62 - Fix handling of errors when resolving names from DNS
68 *(Released Thu, 3 Jun 2010)*
70 A medium sized development cycle. Some new features, and some
71 fixes/small improvements/cleanups.
76 The node deamon now tries to mlock itself into memory, unless the
77 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
78 its logs, and falls back to console logging. This allows emergency
79 features such as ``gnt-node powercycle`` to work even in the event of a
80 broken node disk (tested offlining the disk hosting the node's
81 filesystem and dropping its memory caches; don't try this at home)
83 KVM: add vhost-net acceleration support. It can be tested with a new
84 enough version of the kernel and of qemu-kvm.
86 KVM: Add instance chrooting feature. If you use privilege dropping for
87 your VMs you can also now force them to chroot to an empty directory,
88 before starting the emulated guest.
90 KVM: Add maximum migration bandwith and maximum downtime tweaking
91 support (requires a new-enough version of qemu-kvm).
93 Cluster verify will now warn if the master node doesn't have the master
96 Add a new (incompatible) instance creation request format to RAPI which
97 supports all parameters (previously only a subset was supported, and it
98 wasn't possible to extend the old format to accomodate all the new
99 features. The old format is still supported, and a client can check for
100 this feature, before using it, by checking for its presence in the
101 ``features`` RAPI resource.
103 Now with ancient latin support. Try it passing the ``--roman`` option to
104 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
105 (requires the python-roman module to be installed, in order to work).
110 As usual many internal code refactorings, documentation updates, and
113 - Lots of improvements and cleanups to the experimental Remote API
114 (RAPI) client library.
115 - A new unit test suite for the core daemon libraries.
116 - A fix to creating missing directories makes sure the umask is not
117 applied anymore. This enforces the same directory permissions
119 - Better handling terminating daemons with ctrl+c (used when running
120 them in debugging mode).
121 - Fix a race condition in live migrating a KVM instance, when stat()
122 on the old proc status file returned EINVAL, which is an unexpected
124 - Fixed manpage checking with newer man and utf-8 charachters. But now
125 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
131 *(Released Fri, 7 May 2010)*
133 Fix a bug which prevented untagged KVM instances from starting.
139 *(Released Fri, 7 May 2010)*
141 Another release with a long development cycle, during which many
142 different features were added.
147 The KVM hypervisor now can run the individual instances as non-root, to
148 reduce the impact of a VM being hijacked due to bugs in the
149 hypervisor. It is possible to run all instances as a single (non-root)
150 user, to manually specify a user for each instance, or to dynamically
151 allocate a user out of a cluster-wide pool to each instance, with the
152 guarantee that no two instances will run under the same user ID on any
155 An experimental RAPI client library, that can be used standalone
156 (without the other Ganeti libraries), is provided in the source tree as
157 ``lib/rapi/client.py``. Note this client might change its interface in
158 the future, as we iterate on its capabilities.
160 A new command, ``gnt-cluster renew-crypto`` has been added to easily
161 replace the cluster's certificates and crypto keys. This might help in
162 case they have been compromised, or have simply expired.
164 A new disk option for instance creation has been added that allows one
165 to "adopt" currently existing logical volumes, with data
166 preservation. This should allow easier migration to Ganeti from
167 unmanaged (or managed via other software) instances.
169 Another disk improvement is the possibility to convert between redundant
170 (DRBD) and plain (LVM) disk configuration for an instance. This should
171 allow better scalability (starting with one node and growing the
172 cluster, or shrinking a two-node cluster to one node).
174 A new feature that could help with automated node failovers has been
175 implemented: if a node sees itself as offline (by querying the master
176 candidates), it will try to shutdown (hard) all instances and any active
177 DRBD devices. This reduces the risk of duplicate instances if an
178 external script automatically failovers the instances on such nodes. To
179 enable this, the cluster parameter ``maintain_node_health`` should be
180 enabled; in the future this option (per the name) will enable other
181 automatic maintenance features.
183 Instance export/import now will reuse the original instance
184 specifications for all parameters; that means exporting an instance,
185 deleting it and the importing it back should give an almost identical
186 instance. Note that the default import behaviour has changed from
187 before, where it created only one NIC; now it recreates the original
190 Cluster verify has added a few new checks: SSL certificates validity,
191 /etc/hosts consistency across the cluster, etc.
196 As usual, many internal changes were done, documentation fixes,
199 - Fixed cluster initialization with disabled cluster storage (regression
201 - File-based storage supports growing the disks
202 - Fixed behaviour of node role changes
203 - Fixed cluster verify for some corner cases, plus a general rewrite of
204 cluster verify to allow future extension with more checks
205 - Fixed log spamming by watcher and node daemon (regression introduced
207 - Fixed possible validation issues when changing the list of enabled
209 - Fixed cleanup of /etc/hosts during node removal
210 - Fixed RAPI response for invalid methods
211 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
212 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
213 from ide disks, etc.)
214 - Allow OS changes without re-installation (to record a changed OS
215 outside of Ganeti, or to allow OS renames)
216 - Allow instance creation without OS installation (useful for example if
217 the OS will be installed manually, or restored from a backup not in
219 - Implemented option to make cluster ``copyfile`` use the replication
221 - Added list of enabled hypervisors to ssconf (possibly useful for
223 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
225 - A partial form of node re-IP is possible via node readd, which now
226 allows changed node primary IP
227 - Command line utilities now show an informational message if the job is
229 - The logs of the master daemon now show the PID/UID/GID of the
236 *(Released Fri, 12 Mar 2010)*
238 During the 2.1.0 long release candidate cycle, a lot of improvements and
239 changes have accumulated with were released later as 2.1.1.
244 The node evacuate command (``gnt-node evacuate``) was significantly
245 rewritten, and as such the IAllocator protocol was changed - a new
246 request type has been added. This unfortunate change during a stable
247 series is designed to improve performance of node evacuations; on
248 clusters with more than about five nodes and which are well-balanced,
249 evacuation should proceed in parallel for all instances of the node
250 being evacuated. As such, any existing IAllocator scripts need to be
251 updated, otherwise the above command will fail due to the unknown
252 request. The provided "dumb" allocator has not been updated; but the
253 ganeti-htools package supports the new protocol since version 0.2.4.
255 Another important change is increased validation of node and instance
256 names. This might create problems in special cases, if invalid host
257 names are being used.
259 Also, a new layer of hypervisor parameters has been added, that sits at
260 OS level between the cluster defaults and the instance ones. This allows
261 customisation of virtualization parameters depending on the installed
262 OS. For example instances with OS 'X' may have a different KVM kernel
263 (or any other parameter) than the cluster defaults. This is intended to
264 help managing a multiple OSes on the same cluster, without manual
265 modification of each instance's parameters.
267 A tool for merging clusters, ``cluster-merge``, has been added in the
273 - Improved the int/float conversions that should make the code more
274 robust in face of errors from the node daemons
275 - Fixed the remove node code in case of internal configuration errors
276 - Fixed the node daemon behaviour in face of inconsistent queue
277 directory (e.g. read-only file-system where we can't open the files
279 - Fixed the behaviour of gnt-node modify for master candidate demotion;
280 now it either aborts cleanly or, if given the new “auto_promote”
281 parameter, will automatically promote other nodes as needed
282 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
283 completely prevent Ganeti from working
284 - Fixed bug for instance export when not all disks were successfully
286 - Fixed behaviour of node add when the new node is slow in starting up
288 - Fixed handling of signals in the LUXI client, which should improve
289 behaviour of command-line scripts
290 - Added checks for invalid node/instance names in the configuration (now
291 flagged during cluster verify)
292 - Fixed watcher behaviour for disk activation errors
293 - Fixed two potentially endless loops in http library, which led to the
294 RAPI daemon hanging and consuming 100% CPU in some cases
295 - Fixed bug in RAPI daemon related to hashed passwords
296 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
298 - Enhanced compatibility with non-Debian OSes, but not using absolute
299 path in some commands and allowing customisation of the ssh
300 configuration directory
301 - Fixed possible future issue with new Python versions by abiding to the
302 proper use of ``__slots__`` attribute on classes
303 - Added checks that should prevent directory traversal attacks
304 - Many documentation fixes based on feedback from users
309 - Added an “early_release” more for instance replace disks and node
310 evacuate, where we release locks earlier and thus allow higher
311 parallelism within the cluster
312 - Added watcher hooks, intended to allow the watcher to restart other
313 daemons (e.g. from the ganeti-nbma project), but they can be used of
314 course for any other purpose
315 - Added a compile-time disable for DRBD barriers, to increase
316 performance if the administrator trusts the power supply or the
317 storage system to not lose writes
318 - Added the option of using syslog for logging instead of, or in
319 addition to, Ganeti's own log files
320 - Removed boot restriction for paravirtual NICs for KVM, recent versions
321 can indeed boot from a paravirtual NIC
322 - Added a generic debug level for many operations; while this is not
323 used widely yet, it allows one to pass the debug value all the way to
325 - Enhanced the hooks environment for instance moves (failovers,
326 migrations) where the primary/secondary nodes changed during the
327 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
328 - Enhanced data validations for many user-supplied values; one important
329 item is the restrictions imposed on instance and node names, which
330 might reject some (invalid) host names
331 - Add a configure-time option to disable file-based storage, if it's not
332 needed; this allows greater security separation between the master
333 node and the other nodes from the point of view of the inter-node RPC
335 - Added user notification in interactive tools if job is waiting in the
336 job queue or trying to acquire locks
337 - Added log messages when a job is waiting for locks
338 - Added filtering by node tags in instance operations which admit
339 multiple instances (start, stop, reboot, reinstall)
340 - Added a new tool for cluster mergers, ``cluster-merge``
341 - Parameters from command line which are of the form ``a=b,c=d`` can now
342 use backslash escapes to pass in values which contain commas,
343 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
345 - For KVM, the instance name is the first parameter passed to KVM, so
346 that it's more visible in the process list
352 *(Released Tue, 2 Mar 2010)*
354 Ganeti 2.1 brings many improvements with it. Major changes:
356 - Added infrastructure to ease automated disk repairs
357 - Added new daemon to export configuration data in a cheaper way than
359 - Instance NICs can now be routed instead of being associated with a
361 - Improved job locking logic to reduce impact of jobs acquiring multiple
362 locks waiting for other long-running jobs
364 In-depth implementation details can be found in the Ganeti 2.1 design
370 - Added chroot hypervisor
371 - Added more options to xen-hvm hypervisor (``kernel_path`` and
373 - Added more options to xen-pvm hypervisor (``use_bootloader``,
374 ``bootloader_path`` and ``bootloader_args``)
375 - Added the ``use_localtime`` option for the xen-hvm and kvm
376 hypervisors, and the default value for this has changed to false (in
377 2.0 xen-hvm always enabled it)
378 - Added luxi call to submit multiple jobs in one go
379 - Added cluster initialization option to not modify ``/etc/hosts``
381 - Added network interface parameters
382 - Added dry run mode to some LUs
383 - Added RAPI resources:
385 - ``/2/instances/[instance_name]/info``
386 - ``/2/instances/[instance_name]/replace-disks``
387 - ``/2/nodes/[node_name]/evacuate``
388 - ``/2/nodes/[node_name]/migrate``
389 - ``/2/nodes/[node_name]/role``
390 - ``/2/nodes/[node_name]/storage``
391 - ``/2/nodes/[node_name]/storage/modify``
392 - ``/2/nodes/[node_name]/storage/repair``
394 - Added OpCodes to evacuate or migrate all instances on a node
395 - Added new command to list storage elements on nodes (``gnt-node
396 list-storage``) and modify them (``gnt-node modify-storage``)
397 - Added new ssconf files with master candidate IP address
398 (``ssconf_master_candidates_ips``), node primary IP address
399 (``ssconf_node_primary_ips``) and node secondary IP address
400 (``ssconf_node_secondary_ips``)
401 - Added ``ganeti-confd`` and a client library to query the Ganeti
402 configuration via UDP
403 - Added ability to run hooks after cluster initialization and before
405 - Added automatic mode for disk replace (``gnt-instance replace-disks
407 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
408 after catastrophic data-loss
409 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume
411 - Added ``gnt-instance move`` command to move instances
412 - Added ``gnt-cluster watcher`` command to control watcher
413 - Added ``gnt-node powercycle`` command to powercycle nodes
414 - Added new job status field ``lock_status``
415 - Added parseable error codes to cluster verification (``gnt-cluster
416 verify --error-codes``) and made output less verbose (use
417 ``--verbose`` to restore previous behaviour)
418 - Added UUIDs to the main config entities (cluster, nodes, instances)
419 - Added support for OS variants
420 - Added support for hashed passwords in the Ganeti remote API users file
422 - Added option to specify maximum timeout on instance shutdown
423 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
424 - Added new helper script to start and stop Ganeti daemons
425 (``daemon-util``), with the intent to reduce the work necessary to
426 adjust Ganeti for non-Debian distributions and to start/stop daemons
428 - Added more unittests
429 - Fixed critical bug in ganeti-masterd startup
430 - Removed the configure-time ``kvm-migration-port`` parameter, this is
431 now customisable at the cluster level for both the KVM and Xen
432 hypervisors using the new ``migration_port`` parameter
433 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
434 reinstalling an instance
435 - Allowed ``@`` in tag names
436 - Migrated to Sphinx (http://sphinx.pocoo.org/) for documentation

444 - Improved job locking logic to reduce lock contention
445 - Match instance and node names case insensitively
446 - Reimplemented bash completion script to be more complete
453 *(Released Thu, 4 Feb 2010)*
455 - Fix cleaner behaviour on nodes not in a cluster (Debian bug 568105)
456 - Fix a string formatting bug
457 - Improve safety of the code in some error paths
458 - Improve data validation in the master of values returned from nodes
464 *(Released Thu, 17 Dec 2009)*
466 - Fix security issue due to missing validation of iallocator names; this
467 allows local and remote execution of arbitrary executables
468 - Fix failure of gnt-node list during instance removal
469 - Ship the RAPI documentation in the archive
475 *(Released Wed, 30 Sep 2009)*
477 - Fixed many wrong messages
478 - Fixed a few bugs related to the locking library
479 - Fixed MAC checking at instance creation time
480 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
481 - Fixed a few issues related to signal handling in both daemons and
483 - Fixed the example startup script provided
484 - Fixed insserv dependencies in the example startup script (patch from
486 - Fixed handling of drained nodes in the iallocator framework
487 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
489 - Fixed error related to invalid job IDs in job polling
490 - Fixed job/opcode persistence on unclean master shutdown
491 - Fixed handling of partial job processing after unclean master
493 - Fixed error reporting from LUs, previously all errors were converted
494 into execution errors
495 - Fixed error reporting from burnin
496 - Decreased significantly the memory usage of the job queue
497 - Optimised slightly multi-job submission
498 - Optimised slightly opcode loading
499 - Backported the multi-job submit framework from the development
500 branch; multi-instance start and stop should be faster
501 - Added script to clean archived jobs after 21 days; this will reduce
502 the size of the queue directory
503 - Added some extra checks in disk size tracking
504 - Added an example ethers hook script
505 - Added a cluster parameter that prevents Ganeti from modifying of
507 - Added more node information to RAPI responses
508 - Added a ``gnt-job watch`` command that allows following the ouput of a
510 - Added a bind-address option to ganeti-rapi
511 - Added more checks to the configuration verify
512 - Enhanced the burnin script such that some operations can be retried
514 - Converted instance reinstall to multi-instance model
520 *(Released Fri, 7 Aug 2009)*
522 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
523 to allow using the pre-2.0.2 behaviour in activation, if any existing
524 instances have mismatched disk sizes in the configuration
525 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
526 any configuration mismatches for disk sizes
527 - Added ``gnt-master cluste-failover --no-voting`` to allow master
528 failover to work on two-node clusters
529 - Fixed the ``--net`` option of ``gnt-backup import``, which was
531 - Fixed detection of OS script errors in ``gnt-backup export``
532 - Fixed exit code of ``gnt-backup export``
538 *(Released Fri, 17 Jul 2009)*
540 - Added experimental support for stripped logical volumes; this should
541 enhance performance but comes with a higher complexity in the block
542 device handling; stripping is only enabled when passing
543 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
544 affected even in the non-stripped mode
545 - Improved resiliency against transient failures at the end of DRBD
546 resyncs, and in general of DRBD resync checks
547 - Fixed a couple of issues with exports and snapshot errors
548 - Fixed a couple of issues in instance listing
549 - Added display of the disk size in ``gnt-instance info``
550 - Fixed checking for valid OSes in instance creation
551 - Fixed handling of the "vcpus" parameter in instance listing and in
552 general of invalid parameters
553 - Fixed http server library, and thus RAPI, to handle invalid
554 username/password combinations correctly; this means that now they
555 report unauthorized for queries too, not only for modifications,
556 allowing earlier detect of configuration problems
557 - Added a new "role" node list field, equivalent to the master/master
558 candidate/drained/offline flags combinations
559 - Fixed cluster modify and changes of candidate pool size
560 - Fixed cluster verify error messages for wrong files on regular nodes
561 - Fixed a couple of issues with node demotion from master candidate role
562 - Fixed node readd issues
563 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
564 - Added a new ``--no-voting`` option for masterfailover to fix failover
565 on two-nodes clusters when the former master node is unreachable
566 - Added instance reinstall over RAPI
572 *(Released Tue, 16 Jun 2009)*
574 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
575 allow re-adding the start in single-user option (regression from 1.2)
576 - the watcher writes the instance status to a file, to allow monitoring
577 to report the instance status (from the master) based on cached
578 results of the watcher's queries; while this can get stale if the
579 watcher is being locked due to other work on the cluster, this is
581 - the watcher now also restarts the node daemon and the rapi daemon if
583 - fixed the watcher to handle full and drained queue cases
584 - hooks export more instance data in the environment, which helps if
585 hook scripts need to take action based on the instance's properties
586 (no longer need to query back into ganeti)
587 - instance failovers when the instance is stopped do not check for free
588 RAM, so that failing over a stopped instance is possible in low memory
590 - rapi uses queries for tags instead of jobs (for less job traffic), and
591 for cluster tags it won't talk to masterd at all but read them from
593 - a couple of error handling fixes in RAPI
594 - drbd handling: improved the error handling of inconsistent disks after
595 resync to reduce the frequency of "there are some degraded disks for
596 this instance" messages
597 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
598 error handling path called a wrong function name)
604 *(Released Wed, 27 May 2009)*
606 - no changes from rc5
609 Version 2.0 release candidate 5
610 -------------------------------
612 *(Released Wed, 20 May 2009)*
614 - fix a couple of bugs (validation, argument checks)
615 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
616 - some small improvements to RAPI and IAllocator
617 - make watcher automatically start the master daemon if down
620 Version 2.0 release candidate 4
621 -------------------------------
623 *(Released Mon, 27 Apr 2009)*
625 - change the OS list to not require locks; this helps with big clusters
626 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
627 volume group is broken
628 - ``gnt-instance info``, without any arguments, doesn't run for all
629 instances anymore; either pass ``--all`` or pass the desired
630 instances; this helps against mistakes on big clusters where listing
631 the information for all instances takes a long time
632 - miscellaneous doc and man pages fixes
635 Version 2.0 release candidate 3
636 -------------------------------
638 *(Released Wed, 8 Apr 2009)*
640 - Change the internal locking model of some ``gnt-node`` commands, in
641 order to reduce contention (and blocking of master daemon) when
642 batching many creation/reinstall jobs
643 - Fixes to Xen soft reboot
644 - No longer build documentation at build time, instead distribute it in
645 the archive, in order to reduce the need for the whole docbook/rst
649 Version 2.0 release candidate 2
650 -------------------------------
652 *(Released Fri, 27 Mar 2009)*
654 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
655 - Fix watcher startup sequence, improves the behaviour of busy clusters
656 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
657 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC

659 - Some documentation fixes and updates
662 Version 2.0 release candidate 1
663 -------------------------------
665 *(Released Mon, 2 Mar 2009)*
667 - More documentation updates, now all docs should be more-or-less
669 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
671 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
673 - Fix an issue related to $libdir/run/ganeti and cluster creation
679 *(Released Thu, 19 Feb 2009)*
681 - Xen PVM and KVM have switched the default value for the instance root
682 disk to the first partition on the first drive, instead of the whole
683 drive; this means that the OS installation scripts must be changed
685 - Man pages have been updated
686 - RAPI has been switched by default to HTTPS, and the exported functions
687 should all work correctly
688 - RAPI v1 has been removed
689 - Many improvements to the KVM hypervisor
690 - Block device errors are now better reported
691 - Many other bugfixes and small improvements
697 *(Released Mon, 26 Jan 2009)*
699 - Version 2 is a general rewrite of the code and therefore the
700 differences are too many to list, see the design document for 2.0 in
701 the ``doc/`` subdirectory for more details
702 - In this beta version there is not yet a migration path from 1.2 (there
703 will be one in the final 2.0 release)
704 - A few significant changes are:
706 - all commands are executed by a daemon (``ganeti-masterd``) and the
707 various ``gnt-*`` commands are just front-ends to it
708 - all the commands are entered into, and executed from a job queue,
709 see the ``gnt-job(8)`` manpage
710 - the RAPI daemon supports read-write operations, secured by basic
711 HTTP authentication on top of HTTPS
712 - DRBD version 0.7 support has been removed, DRBD 8 is the only
713 supported version (when migrating from Ganeti 1.2 to 2.0, you need
714 to migrate to DRBD 8 first while still running Ganeti 1.2)
715 - DRBD devices are using statically allocated minor numbers, which
716 will be assigned to existing instances during the migration process
717 - there is support for both Xen PVM and Xen HVM instances running on
719 - KVM virtualization is supported too
720 - file-based storage has been implemented, which means that it is
721 possible to run the cluster without LVM and DRBD storage, for
722 example using a shared filesystem exported from shared storage (and
723 still have live migration)
729 *(Released Tue, 13 Jan 2009)*
731 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
732 - Reuse the old instance mac address by default on instance import, if
733 the instance name is the same.
734 - Handle situations in which the node info rpc returns incomplete
736 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
737 - Improved version of batcher:
740 - instance mac address support
741 - support for HVM clusters/instances
743 - Add an option to show the number of cpu sockets and nodes in
745 - Support OSes that handle more than one version of the OS api (but do
746 not change the current API in any other way)
747 - Fix ``gnt-node migrate``
748 - ``gnt-debug`` man page
749 - Fixes various more typos and small issues
750 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
756 *(Released Wed, 24 Sep 2008)*
758 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
759 type of disk exported to fully virtualized instances.
760 - provide access to the serial console of HVM instances
761 - instance auto_balance flag, set by default. If turned off it will
762 avoid warnings on cluster verify if there is not enough memory to fail
763 over an instance. in the future it will prevent automatically failing
764 it over when we will support that.
765 - batcher tool for instance creation, see ``tools/README.batcher``
766 - ``gnt-instance reinstall --select-os`` to interactively select a new
767 operating system when reinstalling an instance.
768 - when changing the memory amount on instance modify a check has been
769 added that the instance will be able to start. also warnings are
770 emitted if the instance will not be able to fail over, if auto_balance
772 - documentation fixes
773 - sync fields between ``gnt-instance list/modify/add/import``
774 - fix a race condition in drbd when the sync speed was set after giving
775 the device a remote peer.
781 *(Released Tue, 22 Jul 2008)*
783 - note: the allowed size and number of tags per object were reduced
784 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
785 - fixed twisted 8.x compatibility
786 - fixed ``gnt-instance replace-disks`` with iallocator
787 - add TCP keepalives on twisted connections to detect restarted nodes
788 - disk increase support, see ``gnt-instance grow-disk``
789 - implement bulk node/instance query for RAPI
790 - add tags in node/instance listing (optional)
791 - experimental migration (and live migration) support, read the man page
792 for ``gnt-instance migrate``
793 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
794 has some small improvements in handling its state file
800 *(Released Fri, 13 Jun 2008)*
802 - Experimental readonly, REST-based remote API implementation;
803 automatically started on master node, TCP port 5080, if enabled by
804 ``--enable-rapi`` parameter to configure script.
805 - Instance allocator support. Add and import instance accept a
806 ``--iallocator`` parameter, and call that instance allocator to decide
807 which node to use for the instance. The iallocator document describes
808 what's expected from an allocator script.
809 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
810 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
811 node is lost there is still enough memory to fail over the instances
813 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
814 ``gnt-cluster verify``, to check for site-specific compliance. All the
815 hooks will run, and their output, if any, will be displayed. Any
816 failing hook will make the verification return an error value.
817 - ``gnt-cluster verify`` now checks that its peers are reachable on the
818 primary and secondary interfaces
819 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
820 that is still declared as part of the cluster and has failed.
821 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
822 specifying output fields, that just adds the chosen fields to the
824 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
825 export from the filesystem.
826 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
827 have been added. Using them you can enable/disable acpi and pae
828 support, and specify a path for a cd image to be exported to the
829 instance. These parameters as the name suggest only work on HVM
831 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
832 PAE support will be set to the previously hardcoded values, but the
833 (previously hardcoded) path to the CDROM ISO image will be unset and
834 if required, needs to be set manually with ``gnt-instance modify``
836 - The address to which an instance's VNC console is bound is now
837 selectable per-instance, rather than being cluster wide. Of course
838 this only applies to instances controlled via VNC, so currently just
839 applies to HVM clusters.
845 *(Released Mon, 18 Feb 2008)*
847 - more tweaks to the disk activation code (especially helpful for DRBD)
848 - change the default ``gnt-instance list`` output format, now there is
849 one combined status field (see the manpage for the exact values this
851 - some more fixes for the mac export to hooks change
852 - make Ganeti not break with DRBD 8.2.x (which changed the version
853 format in ``/proc/drbd``) (issue 24)
854 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
855 template, allowing migration from DRBD0.7+MD to DRBD8
861 *(Released Wed, 30 Jan 2008)*
863 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
865 - add command aliases infrastructure and a few aliases
866 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
867 man pages and the ``--help`` option of ``gnt-node
868 list``/``gnt-instance list``
869 - fix ``gnt-backup list`` with down nodes (issue 21)
870 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
871 - fix the dist archive and add a check for including svn/git files in
873 - some developer-related changes: improve the burnin and the QA suite,
874 add an upload script for testing during development
880 *(Released Wed, 16 Jan 2008)*
882 - experimental HVM support, read the install document, section
883 "Initializing the cluster"
884 - allow for the PVM hypervisor per-instance kernel and initrd paths
885 - add a new command ``gnt-cluster verify-disks`` which uses a new
886 algorithm to improve the reconnection of the DRBD pairs if the device
887 on the secondary node has gone away
888 - make logical volume code auto-activate LVs at disk activation time
889 - slightly improve the speed of activating disks
890 - allow specification of the MAC address at instance creation time, and
891 changing it later via ``gnt-instance modify``
892 - fix handling of external commands that generate lots of output on
894 - update documentation with regard to minimum version of DRBD8 supported
900 *(Released Tue, 4 Dec 2007)*
902 - Log the ``xm create`` output to the node daemon log on failure (to
903 help diagnosing the error)
904 - In debug mode, log all external commands output if failed to the logs
905 - Change parsing of lvm commands to ignore stderr
911 *(Released Wed, 28 Nov 2007)*
913 - Another round of updates to the DRBD 8 code to deal with more failures
914 in the replace secondary node operation
915 - Some more logging of failures in disk operations (lvm, drbd)
916 - A few documentation updates
923 *(Released Tue, 13 Nov 2007)*
925 - Change configuration file format from Python's Pickle to JSON.
926 Upgrading is possible using the cfgupgrade utility.
927 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
928 faster replace disks and is more stable (DRBD 8 has many improvements
929 compared to DRBD 0.7)
930 - Added command line tags support (see man pages for ``gnt-instance``,
931 ``gnt-node``, ``gnt-cluster``)
932 - Added instance rename support
933 - Added multi-instance startup/shutdown
934 - Added cluster rename support
935 - Added ``gnt-node evacuate`` to simplify some node operations
936 - Added instance reboot operation that can speedup reboot as compared to
938 - Soften the requirement that hostnames are in FQDN format
939 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
941 - Removed dependency on debian's patched fping that uses the
942 non-standard ``-S`` option
943 - Now the OS definitions are searched for in multiple, configurable
944 paths (easier for distros to package)
945 - Some changes to the hooks infrastructure (especially the new
946 post-configuration update hook)
947 - Other small bugfixes
