7 *(Released Thu, 3 Jun 2010)*
9 A medium sized development cycle. Some new features, and some
10 fixes/small improvements/cleanups.
15 The node deamon now tries to mlock itself into memory, unless the
16 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
17 its logs, and falls back to console logging. This allows emergency
18 features such as ``gnt-node powercycle`` to work even in the event of a
19 broken node disk (tested offlining the disk hosting the node's
20 filesystem and dropping its memory caches; don't try this at home)
22 KVM: add vhost-net acceleration support. It can be tested with a new
23 enough version of the kernel and of qemu-kvm.
25 KVM: Add instance chrooting feature. If you use privilege dropping for
26 your VMs you can also now force them to chroot to an empty directory,
27 before starting the emulated guest.
29 KVM: Add maximum migration bandwith and maximum downtime tweaking
30 support (requires a new-enough version of qemu-kvm).
32 Cluster verify will now warn if the master node doesn't have the master
35 Add a new (incompatible) instance creation request format to RAPI which
36 supports all parameters (previously only a subset was supported, and it
37 wasn't possible to extend the old format to accomodate all the new
38 features. The old format is still supported, and a client can check for
39 this feature, before using it, by checking for its presence in the
40 ``features`` RAPI resource.
42 Now with ancient latin support. Try it passing the ``--roman`` option to
43 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
44 (requires the python-roman module to be installed, in order to work).
49 As usual many internal code refactorings, documentation updates, and
52 - Lots of improvements and cleanups to the experimental Remote API
53 (RAPI) client library.
54 - A new unit test suite for the core daemon libraries.
55 - A fix to creating missing directories makes sure the umask is not
56 applied anymore. This enforces the same directory permissions
58 - Better handling terminating daemons with ctrl+c (used when running
59 them in debugging mode).
60 - Fix a race condition in live migrating a KVM instance, when stat()
61 on the old proc status file returned EINVAL, which is an unexpected
63 - Fixed manpage checking with newer man and utf-8 charachters. But now
64 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
70 *(Released Fri, 7 May 2010)*
72 Fix a bug which prevented untagged KVM instances from starting.
78 *(Released Fri, 7 May 2010)*
80 Another release with a long development cycle, during which many
81 different features were added.
86 The KVM hypervisor now can run the individual instances as non-root, to
87 reduce the impact of a VM being hijacked due to bugs in the
88 hypervisor. It is possible to run all instances as a single (non-root)
89 user, to manually specify a user for each instance, or to dynamically
90 allocate a user out of a cluster-wide pool to each instance, with the
91 guarantee that no two instances will run under the same user ID on any
94 An experimental RAPI client library, that can be used standalone
95 (without the other Ganeti libraries), is provided in the source tree as
96 ``lib/rapi/client.py``. Note this client might change its interface in
97 the future, as we iterate on its capabilities.
99 A new command, ``gnt-cluster renew-crypto`` has been added to easily
100 replace the cluster's certificates and crypto keys. This might help in
101 case they have been compromised, or have simply expired.
103 A new disk option for instance creation has been added that allows one
104 to "adopt" currently existing logical volumes, with data
105 preservation. This should allow easier migration to Ganeti from
106 unmanaged (or managed via other software) instances.
108 Another disk improvement is the possibility to convert between redundant
109 (DRBD) and plain (LVM) disk configuration for an instance. This should
110 allow better scalability (starting with one node and growing the
111 cluster, or shrinking a two-node cluster to one node).
113 A new feature that could help with automated node failovers has been
114 implemented: if a node sees itself as offline (by querying the master
115 candidates), it will try to shutdown (hard) all instances and any active
116 DRBD devices. This reduces the risk of duplicate instances if an
117 external script automatically failovers the instances on such nodes. To
118 enable this, the cluster parameter ``maintain_node_health`` should be
119 enabled; in the future this option (per the name) will enable other
120 automatic maintenance features.
122 Instance export/import now will reuse the original instance
123 specifications for all parameters; that means exporting an instance,
124 deleting it and the importing it back should give an almost identical
125 instance. Note that the default import behaviour has changed from
126 before, where it created only one NIC; now it recreates the original
129 Cluster verify has added a few new checks: SSL certificates validity,
130 /etc/hosts consistency across the cluster, etc.
135 As usual, many internal changes were done, documentation fixes,
138 - Fixed cluster initialization with disabled cluster storage (regression
140 - File-based storage supports growing the disks
141 - Fixed behaviour of node role changes
142 - Fixed cluster verify for some corner cases, plus a general rewrite of
143 cluster verify to allow future extension with more checks
144 - Fixed log spamming by watcher and node daemon (regression introduced
146 - Fixed possible validation issues when changing the list of enabled
148 - Fixed cleanup of /etc/hosts during node removal
149 - Fixed RAPI response for invalid methods
150 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
151 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
152 from ide disks, etc.)
153 - Allow OS changes without re-installation (to record a changed OS
154 outside of Ganeti, or to allow OS renames)
155 - Allow instance creation without OS installation (useful for example if
156 the OS will be installed manually, or restored from a backup not in
158 - Implemented option to make cluster ``copyfile`` use the replication
160 - Added list of enabled hypervisors to ssconf (possibly useful for
162 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
164 - A partial form of node re-IP is possible via node readd, which now
165 allows changed node primary IP
166 - Command line utilities now show an informational message if the job is
168 - The logs of the master daemon now show the PID/UID/GID of the
175 *(Released Fri, 12 Mar 2010)*
177 During the 2.1.0 long release candidate cycle, a lot of improvements and
178 changes have accumulated with were released later as 2.1.1.
183 The node evacuate command (``gnt-node evacuate``) was significantly
184 rewritten, and as such the IAllocator protocol was changed - a new
185 request type has been added. This unfortunate change during a stable
186 series is designed to improve performance of node evacuations; on
187 clusters with more than about five nodes and which are well-balanced,
188 evacuation should proceed in parallel for all instances of the node
189 being evacuated. As such, any existing IAllocator scripts need to be
190 updated, otherwise the above command will fail due to the unknown
191 request. The provided "dumb" allocator has not been updated; but the
192 ganeti-htools package supports the new protocol since version 0.2.4.
194 Another important change is increased validation of node and instance
195 names. This might create problems in special cases, if invalid host
196 names are being used.
198 Also, a new layer of hypervisor parameters has been added, that sits at
199 OS level between the cluster defaults and the instance ones. This allows
200 customisation of virtualization parameters depending on the installed
201 OS. For example instances with OS 'X' may have a different KVM kernel
202 (or any other parameter) than the cluster defaults. This is intended to
203 help managing a multiple OSes on the same cluster, without manual
204 modification of each instance's parameters.
206 A tool for merging clusters, ``cluster-merge``, has been added in the
212 - Improved the int/float conversions that should make the code more
213 robust in face of errors from the node daemons
214 - Fixed the remove node code in case of internal configuration errors
215 - Fixed the node daemon behaviour in face of inconsistent queue
216 directory (e.g. read-only file-system where we can't open the files
218 - Fixed the behaviour of gnt-node modify for master candidate demotion;
219 now it either aborts cleanly or, if given the new “auto_promote”
220 parameter, will automatically promote other nodes as needed
221 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
222 completely prevent Ganeti from working
223 - Fixed bug for instance export when not all disks were successfully
225 - Fixed behaviour of node add when the new node is slow in starting up
227 - Fixed handling of signals in the LUXI client, which should improve
228 behaviour of command-line scripts
229 - Added checks for invalid node/instance names in the configuration (now
230 flagged during cluster verify)
231 - Fixed watcher behaviour for disk activation errors
232 - Fixed two potentially endless loops in http library, which led to the
233 RAPI daemon hanging and consuming 100% CPU in some cases
234 - Fixed bug in RAPI daemon related to hashed passwords
235 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
237 - Enhanced compatibility with non-Debian OSes, but not using absolute
238 path in some commands and allowing customisation of the ssh
239 configuration directory
240 - Fixed possible future issue with new Python versions by abiding to the
241 proper use of ``__slots__`` attribute on classes
242 - Added checks that should prevent directory traversal attacks
243 - Many documentation fixes based on feedback from users
248 - Added an “early_release” more for instance replace disks and node
249 evacuate, where we release locks earlier and thus allow higher
250 parallelism within the cluster
251 - Added watcher hooks, intended to allow the watcher to restart other
252 daemons (e.g. from the ganeti-nbma project), but they can be used of
253 course for any other purpose
254 - Added a compile-time disable for DRBD barriers, to increase
255 performance if the administrator trusts the power supply or the
256 storage system to not lose writes
257 - Added the option of using syslog for logging instead of, or in
258 addition to, Ganeti's own log files
259 - Removed boot restriction for paravirtual NICs for KVM, recent versions
260 can indeed boot from a paravirtual NIC
261 - Added a generic debug level for many operations; while this is not
262 used widely yet, it allows one to pass the debug value all the way to
264 - Enhanced the hooks environment for instance moves (failovers,
265 migrations) where the primary/secondary nodes changed during the
266 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
267 - Enhanced data validations for many user-supplied values; one important
268 item is the restrictions imposed on instance and node names, which
269 might reject some (invalid) host names
270 - Add a configure-time option to disable file-based storage, if it's not
271 needed; this allows greater security separation between the master
272 node and the other nodes from the point of view of the inter-node RPC
274 - Added user notification in interactive tools if job is waiting in the
275 job queue or trying to acquire locks
276 - Added log messages when a job is waiting for locks
277 - Added filtering by node tags in instance operations which admit
278 multiple instances (start, stop, reboot, reinstall)
279 - Added a new tool for cluster mergers, ``cluster-merge``
280 - Parameters from command line which are of the form ``a=b,c=d`` can now
281 use backslash escapes to pass in values which contain commas,
282 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
284 - For KVM, the instance name is the first parameter passed to KVM, so
285 that it's more visible in the process list
291 *(Released Tue, 2 Mar 2010)*
293 Ganeti 2.1 brings many improvements with it. Major changes:
295 - Added infrastructure to ease automated disk repairs
296 - Added new daemon to export configuration data in a cheaper way than
298 - Instance NICs can now be routed instead of being associated with a
300 - Improved job locking logic to reduce impact of jobs acquiring multiple
301 locks waiting for other long-running jobs
303 In-depth implementation details can be found in the Ganeti 2.1 design
309 - Added chroot hypervisor
310 - Added more options to xen-hvm hypervisor (``kernel_path`` and
312 - Added more options to xen-pvm hypervisor (``use_bootloader``,
313 ``bootloader_path`` and ``bootloader_args``)
314 - Added the ``use_localtime`` option for the xen-hvm and kvm
315 hypervisors, and the default value for this has changed to false (in
316 2.0 xen-hvm always enabled it)
317 - Added luxi call to submit multiple jobs in one go
318 - Added cluster initialization option to not modify ``/etc/hosts``
320 - Added network interface parameters
321 - Added dry run mode to some LUs
322 - Added RAPI resources:
324 - ``/2/instances/[instance_name]/info``
325 - ``/2/instances/[instance_name]/replace-disks``
326 - ``/2/nodes/[node_name]/evacuate``
327 - ``/2/nodes/[node_name]/migrate``
328 - ``/2/nodes/[node_name]/role``
329 - ``/2/nodes/[node_name]/storage``
330 - ``/2/nodes/[node_name]/storage/modify``
331 - ``/2/nodes/[node_name]/storage/repair``
333 - Added OpCodes to evacuate or migrate all instances on a node
334 - Added new command to list storage elements on nodes (``gnt-node
335 list-storage``) and modify them (``gnt-node modify-storage``)
336 - Added new ssconf files with master candidate IP address
337 (``ssconf_master_candidates_ips``), node primary IP address
338 (``ssconf_node_primary_ips``) and node secondary IP address
339 (``ssconf_node_secondary_ips``)
340 - Added ``ganeti-confd`` and a client library to query the Ganeti
341 configuration via UDP
342 - Added ability to run hooks after cluster initialization and before
344 - Added automatic mode for disk replace (``gnt-instance replace-disks
346 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
347 after catastrophic data-loss
348 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume
350 - Added ``gnt-instance move`` command to move instances
351 - Added ``gnt-cluster watcher`` command to control watcher
352 - Added ``gnt-node powercycle`` command to powercycle nodes
353 - Added new job status field ``lock_status``
354 - Added parseable error codes to cluster verification (``gnt-cluster
355 verify --error-codes``) and made output less verbose (use
356 ``--verbose`` to restore previous behaviour)
357 - Added UUIDs to the main config entities (cluster, nodes, instances)
358 - Added support for OS variants
359 - Added support for hashed passwords in the Ganeti remote API users file
361 - Added option to specify maximum timeout on instance shutdown
362 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
363 - Added new helper script to start and stop Ganeti daemons
364 (``daemon-util``), with the intent to reduce the work necessary to
365 adjust Ganeti for non-Debian distributions and to start/stop daemons
367 - Added more unittests
368 - Fixed critical bug in ganeti-masterd startup
369 - Removed the configure-time ``kvm-migration-port`` parameter, this is
370 now customisable at the cluster level for both the KVM and Xen
371 hypervisors using the new ``migration_port`` parameter
372 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
373 reinstalling an instance
374 - Allowed ``@`` in tag names

392 *(Released Thu, 4 Feb 2010)*
394 - Fix cleaner behaviour on nodes not in a cluster (Debian bug 568105)
395 - Fix a string formatting bug
396 - Improve safety of the code in some error paths
397 - Improve data validation in the master of values returned from nodes
403 *(Released Thu, 17 Dec 2009)*
405 - Fix security issue due to missing validation of iallocator names; this
406 allows local and remote execution of arbitrary executables
407 - Fix failure of gnt-node list during instance removal
408 - Ship the RAPI documentation in the archive
414 *(Released Wed, 30 Sep 2009)*
416 - Fixed many wrong messages
417 - Fixed a few bugs related to the locking library
418 - Fixed MAC checking at instance creation time
419 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
420 - Fixed a few issues related to signal handling in both daemons and
422 - Fixed the example startup script provided
423 - Fixed insserv dependencies in the example startup script (patch from
425 - Fixed handling of drained nodes in the iallocator framework
426 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
428 - Fixed error related to invalid job IDs in job polling
429 - Fixed job/opcode persistence on unclean master shutdown
430 - Fixed handling of partial job processing after unclean master
432 - Fixed error reporting from LUs, previously all errors were converted
433 into execution errors
434 - Fixed error reporting from burnin
435 - Decreased significantly the memory usage of the job queue
436 - Optimised slightly multi-job submission
437 - Optimised slightly opcode loading
438 - Backported the multi-job submit framework from the development
439 branch; multi-instance start and stop should be faster
440 - Added script to clean archived jobs after 21 days; this will reduce
441 the size of the queue directory
442 - Added some extra checks in disk size tracking
443 - Added an example ethers hook script
444 - Added a cluster parameter that prevents Ganeti from modifying of
446 - Added more node information to RAPI responses
447 - Added a ``gnt-job watch`` command that allows following the ouput of a
449 - Added a bind-address option to ganeti-rapi
450 - Added more checks to the configuration verify
451 - Enhanced the burnin script such that some operations can be retried
453 - Converted instance reinstall to multi-instance model
459 *(Released Fri, 7 Aug 2009)*
461 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
462 to allow using the pre-2.0.2 behaviour in activation, if any existing
463 instances have mismatched disk sizes in the configuration
464 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
465 any configuration mismatches for disk sizes
466 - Added ``gnt-master cluste-failover --no-voting`` to allow master
467 failover to work on two-node clusters
468 - Fixed the ``--net`` option of ``gnt-backup import``, which was
470 - Fixed detection of OS script errors in ``gnt-backup export``
471 - Fixed exit code of ``gnt-backup export``
477 *(Released Fri, 17 Jul 2009)*
479 - Added experimental support for stripped logical volumes; this should
480 enhance performance but comes with a higher complexity in the block
481 device handling; stripping is only enabled when passing
482 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
483 affected even in the non-stripped mode
484 - Improved resiliency against transient failures at the end of DRBD
485 resyncs, and in general of DRBD resync checks
486 - Fixed a couple of issues with exports and snapshot errors
487 - Fixed a couple of issues in instance listing
488 - Added display of the disk size in ``gnt-instance info``
489 - Fixed checking for valid OSes in instance creation
490 - Fixed handling of the "vcpus" parameter in instance listing and in
491 general of invalid parameters
492 - Fixed http server library, and thus RAPI, to handle invalid
493 username/password combinations correctly; this means that now they
494 report unauthorized for queries too, not only for modifications,
495 allowing earlier detect of configuration problems
496 - Added a new "role" node list field, equivalent to the master/master
497 candidate/drained/offline flags combinations
498 - Fixed cluster modify and changes of candidate pool size
499 - Fixed cluster verify error messages for wrong files on regular nodes
500 - Fixed a couple of issues with node demotion from master candidate role
501 - Fixed node readd issues
502 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
503 - Added a new ``--no-voting`` option for masterfailover to fix failover
504 on two-nodes clusters when the former master node is unreachable
505 - Added instance reinstall over RAPI
511 *(Released Tue, 16 Jun 2009)*
513 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
514 allow re-adding the start in single-user option (regression from 1.2)
515 - the watcher writes the instance status to a file, to allow monitoring
516 to report the instance status (from the master) based on cached
517 results of the watcher's queries; while this can get stale if the
518 watcher is being locked due to other work on the cluster, this is
520 - the watcher now also restarts the node daemon and the rapi daemon if
522 - fixed the watcher to handle full and drained queue cases
523 - hooks export more instance data in the environment, which helps if
524 hook scripts need to take action based on the instance's properties
525 (no longer need to query back into ganeti)
526 - instance failovers when the instance is stopped do not check for free
527 RAM, so that failing over a stopped instance is possible in low memory
529 - rapi uses queries for tags instead of jobs (for less job traffic), and
530 for cluster tags it won't talk to masterd at all but read them from
532 - a couple of error handling fixes in RAPI
533 - drbd handling: improved the error handling of inconsistent disks after
534 resync to reduce the frequency of "there are some degraded disks for
535 this instance" messages
536 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
537 error handling path called a wrong function name)
543 *(Released Wed, 27 May 2009)*
545 - no changes from rc5
548 Version 2.0 release candidate 5
549 -------------------------------
551 *(Released Wed, 20 May 2009)*
553 - fix a couple of bugs (validation, argument checks)
554 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
555 - some small improvements to RAPI and IAllocator
556 - make watcher automatically start the master daemon if down
559 Version 2.0 release candidate 4
560 -------------------------------
562 *(Released Mon, 27 Apr 2009)*
564 - change the OS list to not require locks; this helps with big clusters
565 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
566 volume group is broken
567 - ``gnt-instance info``, without any arguments, doesn't run for all
568 instances anymore; either pass ``--all`` or pass the desired
569 instances; this helps against mistakes on big clusters where listing
570 the information for all instances takes a long time
571 - miscellaneous doc and man pages fixes
574 Version 2.0 release candidate 3
575 -------------------------------
577 *(Released Wed, 8 Apr 2009)*
579 - Change the internal locking model of some ``gnt-node`` commands, in
580 order to reduce contention (and blocking of master daemon) when
581 batching many creation/reinstall jobs
582 - Fixes to Xen soft reboot
583 - No longer build documentation at build time, instead distribute it in
584 the archive, in order to reduce the need for the whole docbook/rst
588 Version 2.0 release candidate 2
589 -------------------------------
591 *(Released Fri, 27 Mar 2009)*
593 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
594 - Fix watcher startup sequence, improves the behaviour of busy clusters
595 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
596 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
597 bind address and other places
598 - Some documentation fixes and updates
601 Version 2.0 release candidate 1
602 -------------------------------
604 *(Released Mon, 2 Mar 2009)*
606 - More documentation updates, now all docs should be more-or-less
608 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
610 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
612 - Fix an issue related to $libdir/run/ganeti and cluster creation
618 *(Released Thu, 19 Feb 2009)*
620 - Xen PVM and KVM have switched the default value for the instance root
621 disk to the first partition on the first drive, instead of the whole
622 drive; this means that the OS installation scripts must be changed
624 - Man pages have been updated
625 - RAPI has been switched by default to HTTPS, and the exported functions
626 should all work correctly
627 - RAPI v1 has been removed
628 - Many improvements to the KVM hypervisor
629 - Block device errors are now better reported
630 - Many other bugfixes and small improvements
636 *(Released Mon, 26 Jan 2009)*
638 - Version 2 is a general rewrite of the code and therefore the
639 differences are too many to list, see the design document for 2.0 in
640 the ``doc/`` subdirectory for more details
641 - In this beta version there is not yet a migration path from 1.2 (there
642 will be one in the final 2.0 release)
643 - A few significant changes are:
645 - all commands are executed by a daemon (``ganeti-masterd``) and the
646 various ``gnt-*`` commands are just front-ends to it
647 - all the commands are entered into, and executed from a job queue,
648 see the ``gnt-job(8)`` manpage
649 - the RAPI daemon supports read-write operations, secured by basic
650 HTTP authentication on top of HTTPS
651 - DRBD version 0.7 support has been removed, DRBD 8 is the only
652 supported version (when migrating from Ganeti 1.2 to 2.0, you need
653 to migrate to DRBD 8 first while still running Ganeti 1.2)
654 - DRBD devices are using statically allocated minor numbers, which
655 will be assigned to existing instances during the migration process
656 - there is support for both Xen PVM and Xen HVM instances running on
658 - KVM virtualization is supported too
659 - file-based storage has been implemented, which means that it is
660 possible to run the cluster without LVM and DRBD storage, for
661 example using a shared filesystem exported from shared storage (and
662 still have live migration)
668 *(Released Tue, 13 Jan 2009)*
670 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
671 - Reuse the old instance mac address by default on instance import, if
672 the instance name is the same.
673 - Handle situations in which the node info rpc returns incomplete
675 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
676 - Improved version of batcher:
679 - instance mac address support
680 - support for HVM clusters/instances
682 - Add an option to show the number of cpu sockets and nodes in
684 - Support OSes that handle more than one version of the OS api (but do
685 not change the current API in any other way)
686 - Fix ``gnt-node migrate``
687 - ``gnt-debug`` man page
688 - Fixes various more typos and small issues
689 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
695 *(Released Wed, 24 Sep 2008)*
697 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
698 type of disk exported to fully virtualized instances.
699 - provide access to the serial console of HVM instances
700 - instance auto_balance flag, set by default. If turned off it will
701 avoid warnings on cluster verify if there is not enough memory to fail
702 over an instance. in the future it will prevent automatically failing
703 it over when we will support that.
704 - batcher tool for instance creation, see ``tools/README.batcher``
705 - ``gnt-instance reinstall --select-os`` to interactively select a new
706 operating system when reinstalling an instance.
707 - when changing the memory amount on instance modify a check has been
708 added that the instance will be able to start. also warnings are
709 emitted if the instance will not be able to fail over, if auto_balance
711 - documentation fixes
712 - sync fields between ``gnt-instance list/modify/add/import``
713 - fix a race condition in drbd when the sync speed was set after giving
714 the device a remote peer.
720 *(Released Tue, 22 Jul 2008)*
722 - note: the allowed size and number of tags per object were reduced
723 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
724 - fixed twisted 8.x compatibility
725 - fixed ``gnt-instance replace-disks`` with iallocator
726 - add TCP keepalives on twisted connections to detect restarted nodes
727 - disk increase support, see ``gnt-instance grow-disk``
728 - implement bulk node/instance query for RAPI
729 - add tags in node/instance listing (optional)
730 - experimental migration (and live migration) support, read the man page
731 for ``gnt-instance migrate``
732 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
733 has some small improvements in handling its state file
739 *(Released Fri, 13 Jun 2008)*
741 - Experimental readonly, REST-based remote API implementation;
742 automatically started on master node, TCP port 5080, if enabled by
743 ``--enable-rapi`` parameter to configure script.
744 - Instance allocator support. Add and import instance accept a
745 ``--iallocator`` parameter, and call that instance allocator to decide
746 which node to use for the instance. The iallocator document describes
747 what's expected from an allocator script.
748 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
749 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
750 node is lost there is still enough memory to fail over the instances
752 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
753 ``gnt-cluster verify``, to check for site-specific compliance. All the
754 hooks will run, and their output, if any, will be displayed. Any
755 failing hook will make the verification return an error value.
756 - ``gnt-cluster verify`` now checks that its peers are reachable on the
757 primary and secondary interfaces
758 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
759 that is still declared as part of the cluster and has failed.
760 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
761 specifying output fields, that just adds the chosen fields to the
763 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
764 export from the filesystem.
765 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
766 have been added. Using them you can enable/disable acpi and pae
767 support, and specify a path for a cd image to be exported to the
768 instance. These parameters as the name suggest only work on HVM
770 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
771 PAE support will be set to the previously hardcoded values, but the
772 (previously hardcoded) path to the CDROM ISO image will be unset and
773 if required, needs to be set manually with ``gnt-instance modify``
775 - The address to which an instance's VNC console is bound is now
776 selectable per-instance, rather than being cluster wide. Of course
777 this only applies to instances controlled via VNC, so currently just
778 applies to HVM clusters.
784 *(Released Mon, 18 Feb 2008)*
786 - more tweaks to the disk activation code (especially helpful for DRBD)
787 - change the default ``gnt-instance list`` output format, now there is
788 one combined status field (see the manpage for the exact values this
790 - some more fixes for the mac export to hooks change
791 - make Ganeti not break with DRBD 8.2.x (which changed the version
792 format in ``/proc/drbd``) (issue 24)
793 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
794 template, allowing migration from DRBD0.7+MD to DRBD8
800 *(Released Wed, 30 Jan 2008)*
802 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
804 - add command aliases infrastructure and a few aliases
805 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
806 man pages and the ``--help`` option of ``gnt-node
807 list``/``gnt-instance list``
808 - fix ``gnt-backup list`` with down nodes (issue 21)
809 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
810 - fix the dist archive and add a check for including svn/git files in
812 - some developer-related changes: improve the burnin and the QA suite,
813 add an upload script for testing during development
819 *(Released Wed, 16 Jan 2008)*
821 - experimental HVM support, read the install document, section
822 "Initializing the cluster"
823 - allow for the PVM hypervisor per-instance kernel and initrd paths
824 - add a new command ``gnt-cluster verify-disks`` which uses a new
825 algorithm to improve the reconnection of the DRBD pairs if the device
826 on the secondary node has gone away
827 - make logical volume code auto-activate LVs at disk activation time
828 - slightly improve the speed of activating disks
829 - allow specification of the MAC address at instance creation time, and
830 changing it later via ``gnt-instance modify``
831 - fix handling of external commands that generate lots of output on
833 - update documentation with regard to minimum version of DRBD8 supported
839 *(Released Tue, 4 Dec 2007)*
841 - Log the ``xm create`` output to the node daemon log on failure (to
842 help diagnosing the error)
843 - In debug mode, log all external commands output if failed to the logs
844 - Change parsing of lvm commands to ignore stderr
850 *(Released Wed, 28 Nov 2007)*
852 - Another round of updates to the DRBD 8 code to deal with more failures
853 in the replace secondary node operation
854 - Some more logging of failures in disk operations (lvm, drbd)
855 - A few documentation updates
862 *(Released Tue, 13 Nov 2007)*
864 - Change configuration file format from Python's Pickle to JSON.
865 Upgrading is possible using the cfgupgrade utility.
866 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
867 faster replace disks and is more stable (DRBD 8 has many improvements
868 compared to DRBD 0.7)
869 - Added command line tags support (see man pages for ``gnt-instance``,
870 ``gnt-node``, ``gnt-cluster``)
871 - Added instance rename support
872 - Added multi-instance startup/shutdown
873 - Added cluster rename support
874 - Added ``gnt-node evacuate`` to simplify some node operations
875 - Added instance reboot operation that can speedup reboot as compared to
877 - Soften the requirement that hostnames are in FQDN format
878 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
880 - Removed dependency on debian's patched fping that uses the
881 non-standard ``-S`` option
882 - Now the OS definitions are searched for in multiple, configurable
883 paths (easier for distros to package)
884 - Some changes to the hooks infrastructure (especially the new
885 post-configuration update hook)
886 - Other small bugfixes
