7 - RAPI now requires a Content-Type header for requests with a body (e.g.
8 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
9 RFC2616 (HTTP/1.1), section 7.2.1)
17 A medium sized development cycle. Some new features, and some
18 fixes/small improvements/cleanups.
23 The node deamon now tries to mlock itself into memory, unless the
24 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
25 its logs, and falls back to console logging. This allows emergency
26 features such as ``gnt-node powercycle`` to work even in the event of a
27 broken node disk (tested offlining the disk hosting the node's
28 filesystem and dropping its memory caches. don't try this at home)
30 KVM: add vhost-net acceleration support. It can be tested with a new
31 enough version of the kernel and of qemu-kvm.
33 KVM: Add instance chrooting feature. If you use privilege dropping for
34 your VMs you can also now force them to chroot to an empty directory,
35 before starting the emulated guest.
37 KVM: Add maximum migration bandwith and maximum downtime tweaking
38 support (requires a new-enough version of qemu-kvm).
40 Cluster verify will now warn if the master node doesn't have the master
43 Add a new (incompatible) instance creation request format to RAPI which
44 supports all parameters (previously only a subset was supported, and it
45 wasn't possible to extend the old format to accomodate all the new
46 features. The old format is still supported, and a client can check for
47 this feature, before using it, by checking for its presence in the
48 ``features`` RAPI resource.
50 Now with ancient latin support. Try it passing the ``--roman`` option to
51 ``gnt-instance info, gnt-cluster info or gnt-node list`` (requires the
52 python-roman module to be installed, in order to work).
57 As usual many internal code refactorings, documentation updates, and
60 - Lots of improvements and cleanups to the experimental Remote API
61 (RAPI) client library.
62 - A new unit test suite for the core daemon libraries.
63 - A fix to creating missing directories makes sure the umask is not
64 applied anymore. This enforces the same directory permissions
66 - Better handling terminating daemons with ctrl+c (used when running
67 them in debugging mode).
68 - Fix a race condition in live migrating a KVM instance, when stat()
69 on the old proc status file returned EINVAL, which is an unexpected
71 - Fixed manpage checking with newer man and utf-8 charachters. But now
72 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
78 *(Released Fri, 7 May 2010)*
80 Fix a bug which prevented untagged KVM instances from starting.
86 *(Released Fri, 7 May 2010)*
88 Another release with a long development cycle, during which many
89 different features were added.
94 The KVM hypervisor now can run the individual instances as non-root, to
95 reduce the impact of a VM being hijacked due to bugs in the
96 hypervisor. It is possible to run all instances as a single (non-root)
97 user, to manually specify a user for each instance, or to dynamically
98 allocate a user out of a cluster-wide pool to each instance, with the
99 guarantee that no two instances will run under the same user ID on any
102 An experimental RAPI client library, that can be used standalone
103 (without the other Ganeti libraries), is provided in the source tree as
104 ``lib/rapi/client.py``. Note this client might change its interface in
105 the future, as we iterate on its capabilities.
107 A new command, ``gnt-cluster renew-crypto`` has been added to easily
108 replace the cluster's certificates and crypto keys. This might help in
109 case they have been compromised, or have simply expired.
111 A new disk option for instance creation has been added that allows one
112 to "adopt" currently existing logical volumes, with data
113 preservation. This should allow easier migration to Ganeti from
114 unmanaged (or managed via other software) instances.
116 Another disk improvement is the possibility to convert between redundant
117 (DRBD) and plain (LVM) disk configuration for an instance. This should
118 allow better scalability (starting with one node and growing the
119 cluster, or shrinking a two-node cluster to one node).
121 A new feature that could help with automated node failovers has been
122 implemented: if a node sees itself as offline (by querying the master
123 candidates), it will try to shutdown (hard) all instances and any active
124 DRBD devices. This reduces the risk of duplicate instances if an
125 external script automatically failovers the instances on such nodes. To
126 enable this, the cluster parameter ``maintain_node_health`` should be
127 enabled; in the future this option (per the name) will enable other
128 automatic maintenance features.
130 Instance export/import now will reuse the original instance
131 specifications for all parameters; that means exporting an instance,
132 deleting it and the importing it back should give an almost identical
133 instance. Note that the default import behaviour has changed from
134 before, where it created only one NIC; now it recreates the original
137 Cluster verify has added a few new checks: SSL certificates validity,
138 /etc/hosts consistency across the cluster, etc.
143 As usual, many internal changes were done, documentation fixes,
146 - Fixed cluster initialization with disabled cluster storage (regression
148 - File-based storage supports growing the disks
149 - Fixed behaviour of node role changes
150 - Fixed cluster verify for some corner cases, plus a general rewrite of
151 cluster verify to allow future extension with more checks
152 - Fixed log spamming by watcher and node daemon (regression introduced
154 - Fixed possible validation issues when changing the list of enabled
156 - Fixed cleanup of /etc/hosts during node removal
157 - Fixed RAPI response for invalid methods
158 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
159 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
160 from ide disks, etc.)
161 - Allow OS changes without re-installation (to record a changed OS
162 outside of Ganeti, or to allow OS renames)
163 - Allow instance creation without OS installation (useful for example if
164 the OS will be installed manually, or restored from a backup not in
166 - Implemented option to make cluster ``copyfile`` use the replication
168 - Added list of enabled hypervisors to ssconf (possibly useful for
170 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
172 - A partial form of node re-IP is possible via node readd, which now
173 allows changed node primary IP
174 - Command line utilities now show an informational message if the job is
176 - The logs of the master daemon now show the PID/UID/GID of the
183 *(Released Fri, 12 Mar 2010)*
185 During the 2.1.0 long release candidate cycle, a lot of improvements and
186 changes have accumulated with were released later as 2.1.1.
191 The node evacuate command (``gnt-node evacuate``) was significantly
192 rewritten, and as such the IAllocator protocol was changed - a new
193 request type has been added. This unfortunate change during a stable
194 series is designed to improve performance of node evacuations; on
195 clusters with more than about five nodes and which are well-balanced,
196 evacuation should proceed in parallel for all instances of the node
197 being evacuated. As such, any existing IAllocator scripts need to be
198 updated, otherwise the above command will fail due to the unknown
199 request. The provided "dumb" allocator has not been updated; but the
200 ganeti-htools package supports the new protocol since version 0.2.4.
202 Another important change is increased validation of node and instance
203 names. This might create problems in special cases, if invalid host
204 names are being used.
206 Also, a new layer of hypervisor parameters has been added, that sits at
207 OS level between the cluster defaults and the instance ones. This allows
208 customisation of virtualization parameters depending on the installed
209 OS. For example instances with OS 'X' may have a different KVM kernel
210 (or any other parameter) than the cluster defaults. This is intended to
211 help managing a multiple OSes on the same cluster, without manual
212 modification of each instance's parameters.
214 A tool for merging clusters, ``cluster-merge``, has been added in the
220 - Improved the int/float conversions that should make the code more
221 robust in face of errors from the node daemons
222 - Fixed the remove node code in case of internal configuration errors
223 - Fixed the node daemon behaviour in face of inconsistent queue
224 directory (e.g. read-only file-system where we can't open the files
226 - Fixed the behaviour of gnt-node modify for master candidate demotion;
227 now it either aborts cleanly or, if given the new “auto_promote”
228 parameter, will automatically promote other nodes as needed
229 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
230 completely prevent Ganeti from working
231 - Fixed bug for instance export when not all disks were successfully
233 - Fixed behaviour of node add when the new node is slow in starting up
235 - Fixed handling of signals in the LUXI client, which should improve
236 behaviour of command-line scripts
237 - Added checks for invalid node/instance names in the configuration (now
238 flagged during cluster verify)
239 - Fixed watcher behaviour for disk activation errors
240 - Fixed two potentially endless loops in http library, which led to the
241 RAPI daemon hanging and consuming 100% CPU in some cases
242 - Fixed bug in RAPI daemon related to hashed passwords
243 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
245 - Enhanced compatibility with non-Debian OSes, but not using absolute
246 path in some commands and allowing customisation of the ssh
247 configuration directory
248 - Fixed possible future issue with new Python versions by abiding to the
249 proper use of ``__slots__`` attribute on classes
250 - Added checks that should prevent directory traversal attacks
251 - Many documentation fixes based on feedback from users
256 - Added an “early_release” more for instance replace disks and node
257 evacuate, where we release locks earlier and thus allow higher
258 parallelism within the cluster
259 - Added watcher hooks, intended to allow the watcher to restart other
260 daemons (e.g. from the ganeti-nbma project), but they can be used of
261 course for any other purpose
262 - Added a compile-time disable for DRBD barriers, to increase
263 performance if the administrator trusts the power supply or the
264 storage system to not lose writes
265 - Added the option of using syslog for logging instead of, or in
266 addition to, Ganeti's own log files
267 - Removed boot restriction for paravirtual NICs for KVM, recent versions
268 can indeed boot from a paravirtual NIC
269 - Added a generic debug level for many operations; while this is not
270 used widely yet, it allows one to pass the debug value all the way to
272 - Enhanced the hooks environment for instance moves (failovers,
273 migrations) where the primary/secondary nodes changed during the
274 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
275 - Enhanced data validations for many user-supplied values; one important
276 item is the restrictions imposed on instance and node names, which
277 might reject some (invalid) host names
278 - Add a configure-time option to disable file-based storage, if it's not
279 needed; this allows greater security separation between the master
280 node and the other nodes from the point of view of the inter-node RPC
282 - Added user notification in interactive tools if job is waiting in the
283 job queue or trying to acquire locks
284 - Added log messages when a job is waiting for locks
285 - Added filtering by node tags in instance operations which admit
286 multiple instances (start, stop, reboot, reinstall)
287 - Added a new tool for cluster mergers, ``cluster-merge``
288 - Parameters from command line which are of the form ``a=b,c=d`` can now
289 use backslash escapes to pass in values which contain commas,
290 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
292 - For KVM, the instance name is the first parameter passed to KVM, so
293 that it's more visible in the process list
299 *(Released Tue, 2 Mar 2010)*
301 Ganeti 2.1 brings many improvements with it. Major changes:
303 - Added infrastructure to ease automated disk repairs
304 - Added new daemon to export configuration data in a cheaper way than
306 - Instance NICs can now be routed instead of being associated with a
308 - Improved job locking logic to reduce impact of jobs acquiring multiple
309 locks waiting for other long-running jobs
311 In-depth implementation details can be found in the Ganeti 2.1 design
317 - Added chroot hypervisor
318 - Added more options to xen-hvm hypervisor (``kernel_path`` and
320 - Added more options to xen-pvm hypervisor (``use_bootloader``,
321 ``bootloader_path`` and ``bootloader_args``)
322 - Added the ``use_localtime`` option for the xen-hvm and kvm
323 hypervisors, and the default value for this has changed to false (in
324 2.0 xen-hvm always enabled it)
325 - Added luxi call to submit multiple jobs in one go
326 - Added cluster initialization option to not modify ``/etc/hosts``
328 - Added network interface parameters
329 - Added dry run mode to some LUs
330 - Added RAPI resources:
332 - ``/2/instances/[instance_name]/info``
333 - ``/2/instances/[instance_name]/replace-disks``
334 - ``/2/nodes/[node_name]/evacuate``
335 - ``/2/nodes/[node_name]/migrate``
336 - ``/2/nodes/[node_name]/role``
337 - ``/2/nodes/[node_name]/storage``
338 - ``/2/nodes/[node_name]/storage/modify``
339 - ``/2/nodes/[node_name]/storage/repair``
341 - Added OpCodes to evacuate or migrate all instances on a node
342 - Added new command to list storage elements on nodes (``gnt-node
343 list-storage``) and modify them (``gnt-node modify-storage``)
344 - Added new ssconf files with master candidate IP address
345 (``ssconf_master_candidates_ips``), node primary IP address
346 (``ssconf_node_primary_ips``) and node secondary IP address
347 (``ssconf_node_secondary_ips``)
348 - Added ``ganeti-confd`` and a client library to query the Ganeti
349 configuration via UDP
350 - Added ability to run hooks after cluster initialization and before
352 - Added automatic mode for disk replace (``gnt-instance replace-disks
354 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
355 after catastrophic data-loss
356 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume
358 - Added ``gnt-instance move`` command to move instances
359 - Added ``gnt-cluster watcher`` command to control watcher
360 - Added ``gnt-node powercycle`` command to powercycle nodes
361 - Added new job status field ``lock_status``
362 - Added parseable error codes to cluster verification (``gnt-cluster
363 verify --error-codes``) and made output less verbose (use
364 ``--verbose`` to restore previous behaviour)
365 - Added UUIDs to the main config entities (cluster, nodes, instances)
366 - Added support for OS variants
367 - Added support for hashed passwords in the Ganeti remote API users file
369 - Added option to specify maximum timeout on instance shutdown
370 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
371 - Added new helper script to start and stop Ganeti daemons
372 (``daemon-util``), with the intent to reduce the work necessary to
373 adjust Ganeti for non-Debian distributions and to start/stop daemons
375 - Added more unittests
376 - Fixed critical bug in ganeti-masterd startup
377 - Removed the configure-time ``kvm-migration-port`` parameter, this is
378 now customisable at the cluster level for both the KVM and Xen
379 hypervisors using the new ``migration_port`` parameter
380 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
381 reinstalling an instance
382 - Allowed ``@`` in tag names

392 - Match instance and node names case insensitively
393 - Reimplemented bash completion script to be more complete
400 *(Released Thu, 4 Feb 2010)*
402 - Fix cleaner behaviour on nodes not in a cluster (Debian bug 568105)
403 - Fix a string formatting bug
404 - Improve safety of the code in some error paths
405 - Improve data validation in the master of values returned from nodes
411 *(Released Thu, 17 Dec 2009)*
413 - Fix security issue due to missing validation of iallocator names; this
414 allows local and remote execution of arbitrary executables
415 - Fix failure of gnt-node list during instance removal
416 - Ship the RAPI documentation in the archive
422 *(Released Wed, 30 Sep 2009)*
424 - Fixed many wrong messages
425 - Fixed a few bugs related to the locking library
426 - Fixed MAC checking at instance creation time
427 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
428 - Fixed a few issues related to signal handling in both daemons and
430 - Fixed the example startup script provided
431 - Fixed insserv dependencies in the example startup script (patch from
433 - Fixed handling of drained nodes in the iallocator framework
434 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
436 - Fixed error related to invalid job IDs in job polling
437 - Fixed job/opcode persistence on unclean master shutdown
438 - Fixed handling of partial job processing after unclean master
440 - Fixed error reporting from LUs, previously all errors were converted
441 into execution errors
442 - Fixed error reporting from burnin
443 - Decreased significantly the memory usage of the job queue
444 - Optimised slightly multi-job submission
445 - Optimised slightly opcode loading
446 - Backported the multi-job submit framework from the development
447 branch; multi-instance start and stop should be faster
448 - Added script to clean archived jobs after 21 days; this will reduce
449 the size of the queue directory
450 - Added some extra checks in disk size tracking
451 - Added an example ethers hook script
452 - Added a cluster parameter that prevents Ganeti from modifying of
454 - Added more node information to RAPI responses
455 - Added a ``gnt-job watch`` command that allows following the ouput of a
457 - Added a bind-address option to ganeti-rapi
458 - Added more checks to the configuration verify
459 - Enhanced the burnin script such that some operations can be retried
461 - Converted instance reinstall to multi-instance model
467 *(Released Fri, 7 Aug 2009)*
469 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
470 to allow using the pre-2.0.2 behaviour in activation, if any existing
471 instances have mismatched disk sizes in the configuration
472 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
473 any configuration mismatches for disk sizes
474 - Added ``gnt-master cluste-failover --no-voting`` to allow master
475 failover to work on two-node clusters
476 - Fixed the ``--net`` option of ``gnt-backup import``, which was
478 - Fixed detection of OS script errors in ``gnt-backup export``
479 - Fixed exit code of ``gnt-backup export``
485 *(Released Fri, 17 Jul 2009)*
487 - Added experimental support for stripped logical volumes; this should
488 enhance performance but comes with a higher complexity in the block
489 device handling; stripping is only enabled when passing
490 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
491 affected even in the non-stripped mode
492 - Improved resiliency against transient failures at the end of DRBD
493 resyncs, and in general of DRBD resync checks
494 - Fixed a couple of issues with exports and snapshot errors
495 - Fixed a couple of issues in instance listing
496 - Added display of the disk size in ``gnt-instance info``
497 - Fixed checking for valid OSes in instance creation
498 - Fixed handling of the "vcpus" parameter in instance listing and in
499 general of invalid parameters
500 - Fixed http server library, and thus RAPI, to handle invalid
501 username/password combinations correctly; this means that now they
502 report unauthorized for queries too, not only for modifications,
503 allowing earlier detect of configuration problems
504 - Added a new "role" node list field, equivalent to the master/master
505 candidate/drained/offline flags combinations
506 - Fixed cluster modify and changes of candidate pool size
507 - Fixed cluster verify error messages for wrong files on regular nodes
508 - Fixed a couple of issues with node demotion from master candidate role
509 - Fixed node readd issues
510 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
511 - Added a new ``--no-voting`` option for masterfailover to fix failover
512 on two-nodes clusters when the former master node is unreachable
513 - Added instance reinstall over RAPI
519 *(Released Tue, 16 Jun 2009)*
521 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
522 allow re-adding the start in single-user option (regression from 1.2)
523 - the watcher writes the instance status to a file, to allow monitoring
524 to report the instance status (from the master) based on cached
525 results of the watcher's queries; while this can get stale if the
526 watcher is being locked due to other work on the cluster, this is
528 - the watcher now also restarts the node daemon and the rapi daemon if
530 - fixed the watcher to handle full and drained queue cases
531 - hooks export more instance data in the environment, which helps if
532 hook scripts need to take action based on the instance's properties
533 (no longer need to query back into ganeti)
534 - instance failovers when the instance is stopped do not check for free
535 RAM, so that failing over a stopped instance is possible in low memory
537 - rapi uses queries for tags instead of jobs (for less job traffic), and
538 for cluster tags it won't talk to masterd at all but read them from
540 - a couple of error handling fixes in RAPI
541 - drbd handling: improved the error handling of inconsistent disks after
542 resync to reduce the frequency of "there are some degraded disks for
543 this instance" messages
544 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
545 error handling path called a wrong function name)
551 *(Released Wed, 27 May 2009)*
553 - no changes from rc5
556 Version 2.0 release candidate 5
557 -------------------------------
559 *(Released Wed, 20 May 2009)*
561 - fix a couple of bugs (validation, argument checks)
562 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
563 - some small improvements to RAPI and IAllocator
564 - make watcher automatically start the master daemon if down
567 Version 2.0 release candidate 4
568 -------------------------------
570 *(Released Mon, 27 Apr 2009)*
572 - change the OS list to not require locks; this helps with big clusters
573 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
574 volume group is broken
575 - ``gnt-instance info``, without any arguments, doesn't run for all
576 instances anymore; either pass ``--all`` or pass the desired
577 instances; this helps against mistakes on big clusters where listing
578 the information for all instances takes a long time
579 - miscellaneous doc and man pages fixes
582 Version 2.0 release candidate 3
583 -------------------------------
585 *(Released Wed, 8 Apr 2009)*
587 - Change the internal locking model of some ``gnt-node`` commands, in
588 order to reduce contention (and blocking of master daemon) when
589 batching many creation/reinstall jobs
590 - Fixes to Xen soft reboot
591 - No longer build documentation at build time, instead distribute it in
592 the archive, in order to reduce the need for the whole docbook/rst
596 Version 2.0 release candidate 2
597 -------------------------------
599 *(Released Fri, 27 Mar 2009)*
601 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
602 - Fix watcher startup sequence, improves the behaviour of busy clusters
603 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
604 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
605 bind address and other places
606 - Some documentation fixes and updates
609 Version 2.0 release candidate 1
610 -------------------------------
612 *(Released Mon, 2 Mar 2009)*
614 - More documentation updates, now all docs should be more-or-less
616 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
618 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
620 - Fix an issue related to $libdir/run/ganeti and cluster creation
626 *(Released Thu, 19 Feb 2009)*
628 - Xen PVM and KVM have switched the default value for the instance root
629 disk to the first partition on the first drive, instead of the whole
630 drive; this means that the OS installation scripts must be changed
632 - Man pages have been updated
633 - RAPI has been switched by default to HTTPS, and the exported functions
634 should all work correctly
635 - RAPI v1 has been removed
636 - Many improvements to the KVM hypervisor
637 - Block device errors are now better reported
638 - Many other bugfixes and small improvements
644 *(Released Mon, 26 Jan 2009)*
646 - Version 2 is a general rewrite of the code and therefore the
647 differences are too many to list, see the design document for 2.0 in
648 the ``doc/`` subdirectory for more details
649 - In this beta version there is not yet a migration path from 1.2 (there
650 will be one in the final 2.0 release)
651 - A few significant changes are:
653 - all commands are executed by a daemon (``ganeti-masterd``) and the
654 various ``gnt-*`` commands are just front-ends to it
655 - all the commands are entered into, and executed from a job queue,
656 see the ``gnt-job(8)`` manpage
657 - the RAPI daemon supports read-write operations, secured by basic
658 HTTP authentication on top of HTTPS
659 - DRBD version 0.7 support has been removed, DRBD 8 is the only
660 supported version (when migrating from Ganeti 1.2 to 2.0, you need
661 to migrate to DRBD 8 first while still running Ganeti 1.2)
662 - DRBD devices are using statically allocated minor numbers, which
663 will be assigned to existing instances during the migration process
664 - there is support for both Xen PVM and Xen HVM instances running on
666 - KVM virtualization is supported too
667 - file-based storage has been implemented, which means that it is
668 possible to run the cluster without LVM and DRBD storage, for
669 example using a shared filesystem exported from shared storage (and
670 still have live migration)
676 *(Released Tue, 13 Jan 2009)*
678 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
679 - Reuse the old instance mac address by default on instance import, if
680 the instance name is the same.
681 - Handle situations in which the node info rpc returns incomplete
683 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
684 - Improved version of batcher:
687 - instance mac address support
688 - support for HVM clusters/instances
690 - Add an option to show the number of cpu sockets and nodes in
692 - Support OSes that handle more than one version of the OS api (but do
693 not change the current API in any other way)
694 - Fix ``gnt-node migrate``
695 - ``gnt-debug`` man page
696 - Fixes various more typos and small issues
697 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
703 *(Released Wed, 24 Sep 2008)*
705 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
706 type of disk exported to fully virtualized instances.
707 - provide access to the serial console of HVM instances
708 - instance auto_balance flag, set by default. If turned off it will
709 avoid warnings on cluster verify if there is not enough memory to fail
710 over an instance. in the future it will prevent automatically failing
711 it over when we will support that.
712 - batcher tool for instance creation, see ``tools/README.batcher``
713 - ``gnt-instance reinstall --select-os`` to interactively select a new
714 operating system when reinstalling an instance.
715 - when changing the memory amount on instance modify a check has been
716 added that the instance will be able to start. also warnings are
717 emitted if the instance will not be able to fail over, if auto_balance
719 - documentation fixes
720 - sync fields between ``gnt-instance list/modify/add/import``
721 - fix a race condition in drbd when the sync speed was set after giving
722 the device a remote peer.
728 *(Released Tue, 22 Jul 2008)*
730 - note: the allowed size and number of tags per object were reduced
731 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
732 - fixed twisted 8.x compatibility
733 - fixed ``gnt-instance replace-disks`` with iallocator
734 - add TCP keepalives on twisted connections to detect restarted nodes
735 - disk increase support, see ``gnt-instance grow-disk``
736 - implement bulk node/instance query for RAPI
737 - add tags in node/instance listing (optional)
738 - experimental migration (and live migration) support, read the man page
739 for ``gnt-instance migrate``
740 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
741 has some small improvements in handling its state file
747 *(Released Fri, 13 Jun 2008)*
749 - Experimental readonly, REST-based remote API implementation;
750 automatically started on master node, TCP port 5080, if enabled by
751 ``--enable-rapi`` parameter to configure script.
752 - Instance allocator support. Add and import instance accept a
753 ``--iallocator`` parameter, and call that instance allocator to decide
754 which node to use for the instance. The iallocator document describes
755 what's expected from an allocator script.
756 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
757 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
758 node is lost there is still enough memory to fail over the instances
760 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
761 ``gnt-cluster verify``, to check for site-specific compliance. All the
762 hooks will run, and their output, if any, will be displayed. Any
763 failing hook will make the verification return an error value.
764 - ``gnt-cluster verify`` now checks that its peers are reachable on the
765 primary and secondary interfaces
766 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
767 that is still declared as part of the cluster and has failed.
768 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
769 specifying output fields, that just adds the chosen fields to the
771 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
772 export from the filesystem.
773 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
774 have been added. Using them you can enable/disable acpi and pae
775 support, and specify a path for a cd image to be exported to the
776 instance. These parameters as the name suggest only work on HVM
778 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
779 PAE support will be set to the previously hardcoded values, but the
780 (previously hardcoded) path to the CDROM ISO image will be unset and
781 if required, needs to be set manually with ``gnt-instance modify``
783 - The address to which an instance's VNC console is bound is now
784 selectable per-instance, rather than being cluster wide. Of course
785 this only applies to instances controlled via VNC, so currently just
786 applies to HVM clusters.
792 *(Released Mon, 18 Feb 2008)*
794 - more tweaks to the disk activation code (especially helpful for DRBD)
795 - change the default ``gnt-instance list`` output format, now there is
796 one combined status field (see the manpage for the exact values this
798 - some more fixes for the mac export to hooks change
799 - make Ganeti not break with DRBD 8.2.x (which changed the version
800 format in ``/proc/drbd``) (issue 24)
801 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
802 template, allowing migration from DRBD0.7+MD to DRBD8
808 *(Released Wed, 30 Jan 2008)*
810 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
812 - add command aliases infrastructure and a few aliases
813 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
814 man pages and the ``--help`` option of ``gnt-node
815 list``/``gnt-instance list``
816 - fix ``gnt-backup list`` with down nodes (issue 21)
817 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
818 - fix the dist archive and add a check for including svn/git files in
820 - some developer-related changes: improve the burnin and the QA suite,
821 add an upload script for testing during development
827 *(Released Wed, 16 Jan 2008)*
829 - experimental HVM support, read the install document, section
830 "Initializing the cluster"
831 - allow for the PVM hypervisor per-instance kernel and initrd paths
832 - add a new command ``gnt-cluster verify-disks`` which uses a new
833 algorithm to improve the reconnection of the DRBD pairs if the device
834 on the secondary node has gone away
835 - make logical volume code auto-activate LVs at disk activation time
836 - slightly improve the speed of activating disks
837 - allow specification of the MAC address at instance creation time, and
838 changing it later via ``gnt-instance modify``
839 - fix handling of external commands that generate lots of output on
841 - update documentation with regard to minimum version of DRBD8 supported
847 *(Released Tue, 4 Dec 2007)*
849 - Log the ``xm create`` output to the node daemon log on failure (to
850 help diagnosing the error)
851 - In debug mode, log all external commands output if failed to the logs
852 - Change parsing of lvm commands to ignore stderr
858 *(Released Wed, 28 Nov 2007)*
860 - Another round of updates to the DRBD 8 code to deal with more failures
861 in the replace secondary node operation
862 - Some more logging of failures in disk operations (lvm, drbd)
863 - A few documentation updates
870 *(Released Tue, 13 Nov 2007)*
872 - Change configuration file format from Python's Pickle to JSON.
873 Upgrading is possible using the cfgupgrade utility.
874 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
875 faster replace disks and is more stable (DRBD 8 has many improvements
876 compared to DRBD 0.7)
877 - Added command line tags support (see man pages for ``gnt-instance``,
878 ``gnt-node``, ``gnt-cluster``)
879 - Added instance rename support
880 - Added multi-instance startup/shutdown
881 - Added cluster rename support
882 - Added ``gnt-node evacuate`` to simplify some node operations
883 - Added instance reboot operation that can speedup reboot as compared to
885 - Soften the requirement that hostnames are in FQDN format
886 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
888 - Removed dependency on debian's patched fping that uses the
889 non-standard ``-S`` option
890 - Now the OS definitions are searched for in multiple, configurable
891 paths (easier for distros to package)
892 - Some changes to the hooks infrastructure (especially the new
893 post-configuration update hook)
894 - Other small bugfixes
