7 *(Released Thu, 17 Jun 2010)*
9 - Added tool (``move-instance``) and infrastructure to move instances
10 between separate clusters (see :doc:`separate documentation
11 <move-instance>` and :doc:`design document <design-2.2>`)
12 - Added per-request RPC timeout
13 - RAPI now requires a Content-Type header for requests with a body (e.g.
14 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
15 RFC2616 (HTTP/1.1), section 7.2.1)
16 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
18 - Implemented initial support for running Ganeti daemons as separate
19 users, see configure-time flags ``--with-user-prefix`` and
20 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
22 - Instances can be removed after export (``gnt-backup export
24 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
25 key (instead of 1024 bit)
26 - Added new cluster configuration file for cluster domain secret
27 - Import/export now use SSL instead of SSH
28 - Added support for showing estimated time when exporting an instance,
29 see the ``ganeti-os-interface(7)`` manpage and look for
36 *(Released Thu, 01 Jul 2010)*
38 A small bugfix release:
39 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
40 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
42 - Fix instance create: the --force-variant option was ignored
43 - Improve pylint 0.21 compatibility and warnings with Python 2.6
44 - Fix modify node storage with non-FQDN arguments
45 - Fix RAPI client to authenticate under Python 2.6 when used
46 for more than 5 requests needing authentication
47 - Fix gnt-instance modify -t (storage) giving a wrong error message
48 when converting a non-shutdown drbd instance to plain
54 *(Released Fri, 18 Jun 2010)*
56 A small bugfix release:
58 - Fix live migration of KVM instances started with older Ganeti
59 versions which had fewer hypervisor parameters
60 - Fix gnt-instance grow-disk on down instances
61 - Fix an error-reporting bug during instance migration
62 - Better checking of the ``--net`` and ``--disk`` values, to avoid
63 silently ignoring broken ones
64 - Fix an RPC error reporting bug affecting, for example, RAPI client
66 - Fix bug triggered by different API version os-es on different nodes
67 - Fix a bug in instance startup with custom hvparams: OS level
68 parameters would fail to be applied.
69 - Fix the RAPI client under Python 2.6 (but more work is needed to
70 make it work completely well with OpenSSL)
71 - Fix handling of errors when resolving names from DNS
77 *(Released Thu, 3 Jun 2010)*
79 A medium sized development cycle. Some new features, and some
80 fixes/small improvements/cleanups.
85 The node deamon now tries to mlock itself into memory, unless the
86 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
87 its logs, and falls back to console logging. This allows emergency
88 features such as ``gnt-node powercycle`` to work even in the event of a
89 broken node disk (tested offlining the disk hosting the node's
90 filesystem and dropping its memory caches; don't try this at home)
92 KVM: add vhost-net acceleration support. It can be tested with a new
93 enough version of the kernel and of qemu-kvm.
95 KVM: Add instance chrooting feature. If you use privilege dropping for
96 your VMs you can also now force them to chroot to an empty directory,
97 before starting the emulated guest.
99 KVM: Add maximum migration bandwith and maximum downtime tweaking
100 support (requires a new-enough version of qemu-kvm).
102 Cluster verify will now warn if the master node doesn't have the master
105 Add a new (incompatible) instance creation request format to RAPI which
106 supports all parameters (previously only a subset was supported, and it
107 wasn't possible to extend the old format to accomodate all the new
108 features. The old format is still supported, and a client can check for
109 this feature, before using it, by checking for its presence in the
110 ``features`` RAPI resource.
112 Now with ancient latin support. Try it passing the ``--roman`` option to
113 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
114 (requires the python-roman module to be installed, in order to work).
119 As usual many internal code refactorings, documentation updates, and
122 - Lots of improvements and cleanups to the experimental Remote API
123 (RAPI) client library.
124 - A new unit test suite for the core daemon libraries.
125 - A fix to creating missing directories makes sure the umask is not
126 applied anymore. This enforces the same directory permissions
128 - Better handling terminating daemons with ctrl+c (used when running
129 them in debugging mode).
130 - Fix a race condition in live migrating a KVM instance, when stat()
131 on the old proc status file returned EINVAL, which is an unexpected
133 - Fixed manpage checking with newer man and utf-8 charachters. But now
134 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
140 *(Released Fri, 7 May 2010)*
142 Fix a bug which prevented untagged KVM instances from starting.
148 *(Released Fri, 7 May 2010)*
150 Another release with a long development cycle, during which many
151 different features were added.
156 The KVM hypervisor now can run the individual instances as non-root, to
157 reduce the impact of a VM being hijacked due to bugs in the
158 hypervisor. It is possible to run all instances as a single (non-root)
159 user, to manually specify a user for each instance, or to dynamically
160 allocate a user out of a cluster-wide pool to each instance, with the
161 guarantee that no two instances will run under the same user ID on any
164 An experimental RAPI client library, that can be used standalone
165 (without the other Ganeti libraries), is provided in the source tree as
166 ``lib/rapi/client.py``. Note this client might change its interface in
167 the future, as we iterate on its capabilities.
169 A new command, ``gnt-cluster renew-crypto`` has been added to easily
170 replace the cluster's certificates and crypto keys. This might help in
171 case they have been compromised, or have simply expired.
173 A new disk option for instance creation has been added that allows one
174 to "adopt" currently existing logical volumes, with data
175 preservation. This should allow easier migration to Ganeti from
176 unmanaged (or managed via other software) instances.
178 Another disk improvement is the possibility to convert between redundant
179 (DRBD) and plain (LVM) disk configuration for an instance. This should
180 allow better scalability (starting with one node and growing the
181 cluster, or shrinking a two-node cluster to one node).
183 A new feature that could help with automated node failovers has been
184 implemented: if a node sees itself as offline (by querying the master
185 candidates), it will try to shutdown (hard) all instances and any active
186 DRBD devices. This reduces the risk of duplicate instances if an
187 external script automatically failovers the instances on such nodes. To
188 enable this, the cluster parameter ``maintain_node_health`` should be
189 enabled; in the future this option (per the name) will enable other
190 automatic maintenance features.
192 Instance export/import now will reuse the original instance
193 specifications for all parameters; that means exporting an instance,
194 deleting it and the importing it back should give an almost identical
195 instance. Note that the default import behaviour has changed from
196 before, where it created only one NIC; now it recreates the original
199 Cluster verify has added a few new checks: SSL certificates validity,
200 /etc/hosts consistency across the cluster, etc.
205 As usual, many internal changes were done, documentation fixes,
208 - Fixed cluster initialization with disabled cluster storage (regression
210 - File-based storage supports growing the disks
211 - Fixed behaviour of node role changes
212 - Fixed cluster verify for some corner cases, plus a general rewrite of
213 cluster verify to allow future extension with more checks
214 - Fixed log spamming by watcher and node daemon (regression introduced
216 - Fixed possible validation issues when changing the list of enabled
218 - Fixed cleanup of /etc/hosts during node removal
219 - Fixed RAPI response for invalid methods
220 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
221 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
222 from ide disks, etc.)
223 - Allow OS changes without re-installation (to record a changed OS
224 outside of Ganeti, or to allow OS renames)
225 - Allow instance creation without OS installation (useful for example if
226 the OS will be installed manually, or restored from a backup not in
228 - Implemented option to make cluster ``copyfile`` use the replication
230 - Added list of enabled hypervisors to ssconf (possibly useful for
232 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
234 - A partial form of node re-IP is possible via node readd, which now
235 allows changed node primary IP
236 - Command line utilities now show an informational message if the job is
238 - The logs of the master daemon now show the PID/UID/GID of the
245 *(Released Fri, 12 Mar 2010)*
247 During the 2.1.0 long release candidate cycle, a lot of improvements and
248 changes have accumulated with were released later as 2.1.1.
253 The node evacuate command (``gnt-node evacuate``) was significantly
254 rewritten, and as such the IAllocator protocol was changed - a new
255 request type has been added. This unfortunate change during a stable
256 series is designed to improve performance of node evacuations; on
257 clusters with more than about five nodes and which are well-balanced,
258 evacuation should proceed in parallel for all instances of the node
259 being evacuated. As such, any existing IAllocator scripts need to be
260 updated, otherwise the above command will fail due to the unknown
261 request. The provided "dumb" allocator has not been updated; but the
262 ganeti-htools package supports the new protocol since version 0.2.4.
264 Another important change is increased validation of node and instance
265 names. This might create problems in special cases, if invalid host
266 names are being used.
268 Also, a new layer of hypervisor parameters has been added, that sits at
269 OS level between the cluster defaults and the instance ones. This allows
270 customisation of virtualization parameters depending on the installed
271 OS. For example instances with OS 'X' may have a different KVM kernel
272 (or any other parameter) than the cluster defaults. This is intended to
273 help managing a multiple OSes on the same cluster, without manual
274 modification of each instance's parameters.
276 A tool for merging clusters, ``cluster-merge``, has been added in the
282 - Improved the int/float conversions that should make the code more
283 robust in face of errors from the node daemons
284 - Fixed the remove node code in case of internal configuration errors
285 - Fixed the node daemon behaviour in face of inconsistent queue
286 directory (e.g. read-only file-system where we can't open the files
288 - Fixed the behaviour of gnt-node modify for master candidate demotion;
289 now it either aborts cleanly or, if given the new “auto_promote”
290 parameter, will automatically promote other nodes as needed
291 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
292 completely prevent Ganeti from working
293 - Fixed bug for instance export when not all disks were successfully
295 - Fixed behaviour of node add when the new node is slow in starting up
297 - Fixed handling of signals in the LUXI client, which should improve
298 behaviour of command-line scripts
299 - Added checks for invalid node/instance names in the configuration (now
300 flagged during cluster verify)
301 - Fixed watcher behaviour for disk activation errors
302 - Fixed two potentially endless loops in http library, which led to the
303 RAPI daemon hanging and consuming 100% CPU in some cases
304 - Fixed bug in RAPI daemon related to hashed passwords
305 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
307 - Enhanced compatibility with non-Debian OSes, but not using absolute
308 path in some commands and allowing customisation of the ssh
309 configuration directory
310 - Fixed possible future issue with new Python versions by abiding to the
311 proper use of ``__slots__`` attribute on classes
312 - Added checks that should prevent directory traversal attacks
313 - Many documentation fixes based on feedback from users
318 - Added an “early_release” more for instance replace disks and node
319 evacuate, where we release locks earlier and thus allow higher
320 parallelism within the cluster
321 - Added watcher hooks, intended to allow the watcher to restart other
322 daemons (e.g. from the ganeti-nbma project), but they can be used of
323 course for any other purpose
324 - Added a compile-time disable for DRBD barriers, to increase
325 performance if the administrator trusts the power supply or the
326 storage system to not lose writes
327 - Added the option of using syslog for logging instead of, or in
328 addition to, Ganeti's own log files
329 - Removed boot restriction for paravirtual NICs for KVM, recent versions
330 can indeed boot from a paravirtual NIC
331 - Added a generic debug level for many operations; while this is not
332 used widely yet, it allows one to pass the debug value all the way to
334 - Enhanced the hooks environment for instance moves (failovers,
335 migrations) where the primary/secondary nodes changed during the
336 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
337 - Enhanced data validations for many user-supplied values; one important
338 item is the restrictions imposed on instance and node names, which
339 might reject some (invalid) host names
340 - Add a configure-time option to disable file-based storage, if it's not
341 needed; this allows greater security separation between the master
342 node and the other nodes from the point of view of the inter-node RPC
344 - Added user notification in interactive tools if job is waiting in the
345 job queue or trying to acquire locks
346 - Added log messages when a job is waiting for locks
347 - Added filtering by node tags in instance operations which admit
348 multiple instances (start, stop, reboot, reinstall)
349 - Added a new tool for cluster mergers, ``cluster-merge``
350 - Parameters from command line which are of the form ``a=b,c=d`` can now
351 use backslash escapes to pass in values which contain commas,
352 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
354 - For KVM, the instance name is the first parameter passed to KVM, so
355 that it's more visible in the process list
361 *(Released Tue, 2 Mar 2010)*
363 Ganeti 2.1 brings many improvements with it. Major changes:
365 - Added infrastructure to ease automated disk repairs
366 - Added new daemon to export configuration data in a cheaper way than
368 - Instance NICs can now be routed instead of being associated with a
370 - Improved job locking logic to reduce impact of jobs acquiring multiple
371 locks waiting for other long-running jobs
373 In-depth implementation details can be found in the Ganeti 2.1 design
379 - Added chroot hypervisor
380 - Added more options to xen-hvm hypervisor (``kernel_path`` and
382 - Added more options to xen-pvm hypervisor (``use_bootloader``,
383 ``bootloader_path`` and ``bootloader_args``)
384 - Added the ``use_localtime`` option for the xen-hvm and kvm
385 hypervisors, and the default value for this has changed to false (in
386 2.0 xen-hvm always enabled it)
387 - Added luxi call to submit multiple jobs in one go
388 - Added cluster initialization option to not modify ``/etc/hosts``
390 - Added network interface parameters
391 - Added dry run mode to some LUs
392 - Added RAPI resources:
394 - ``/2/instances/[instance_name]/info``
395 - ``/2/instances/[instance_name]/replace-disks``
396 - ``/2/nodes/[node_name]/evacuate``
397 - ``/2/nodes/[node_name]/migrate``
398 - ``/2/nodes/[node_name]/role``
399 - ``/2/nodes/[node_name]/storage``
400 - ``/2/nodes/[node_name]/storage/modify``
401 - ``/2/nodes/[node_name]/storage/repair``
403 - Added OpCodes to evacuate or migrate all instances on a node
404 - Added new command to list storage elements on nodes (``gnt-node
405 list-storage``) and modify them (``gnt-node modify-storage``)
406 - Added new ssconf files with master candidate IP address
407 (``ssconf_master_candidates_ips``), node primary IP address
408 (``ssconf_node_primary_ips``) and node secondary IP address
409 (``ssconf_node_secondary_ips``)
410 - Added ``ganeti-confd`` and a client library to query the Ganeti
411 configuration via UDP
412 - Added ability to run hooks after cluster initialization and before
414 - Added automatic mode for disk replace (``gnt-instance replace-disks
416 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
417 after catastrophic data-loss
418 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume
420 - Added ``gnt-instance move`` command to move instances
421 - Added ``gnt-cluster watcher`` command to control watcher
422 - Added ``gnt-node powercycle`` command to powercycle nodes
423 - Added new job status field ``lock_status``
424 - Added parseable error codes to cluster verification (``gnt-cluster
425 verify --error-codes``) and made output less verbose (use
426 ``--verbose`` to restore previous behaviour)
427 - Added UUIDs to the main config entities (cluster, nodes, instances)
428 - Added support for OS variants
429 - Added support for hashed passwords in the Ganeti remote API users file
431 - Added option to specify maximum timeout on instance shutdown
432 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
433 - Added new helper script to start and stop Ganeti daemons
434 (``daemon-util``), with the intent to reduce the work necessary to
435 adjust Ganeti for non-Debian distributions and to start/stop daemons
437 - Added more unittests
438 - Fixed critical bug in ganeti-masterd startup
439 - Removed the configure-time ``kvm-migration-port`` parameter, this is
440 now customisable at the cluster level for both the KVM and Xen
441 hypervisors using the new ``migration_port`` parameter
442 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
443 reinstalling an instance
444 - Allowed ``@`` in tag names

453 - Improved job locking logic to reduce lock contention
454 - Match instance and node names case insensitively
455 - Reimplemented bash completion script to be more complete
462 *(Released Thu, 4 Feb 2010)*
464 - Fix cleaner behaviour on nodes not in a cluster (Debian bug 568105)
465 - Fix a string formatting bug
466 - Improve safety of the code in some error paths
467 - Improve data validation in the master of values returned from nodes
473 *(Released Thu, 17 Dec 2009)*
475 - Fix security issue due to missing validation of iallocator names; this
476 allows local and remote execution of arbitrary executables
477 - Fix failure of gnt-node list during instance removal
478 - Ship the RAPI documentation in the archive
484 *(Released Wed, 30 Sep 2009)*
486 - Fixed many wrong messages
487 - Fixed a few bugs related to the locking library
488 - Fixed MAC checking at instance creation time
489 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
490 - Fixed a few issues related to signal handling in both daemons and
492 - Fixed the example startup script provided
493 - Fixed insserv dependencies in the example startup script (patch from
495 - Fixed handling of drained nodes in the iallocator framework
496 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
498 - Fixed error related to invalid job IDs in job polling
499 - Fixed job/opcode persistence on unclean master shutdown
500 - Fixed handling of partial job processing after unclean master
502 - Fixed error reporting from LUs, previously all errors were converted
503 into execution errors
504 - Fixed error reporting from burnin
505 - Decreased significantly the memory usage of the job queue
506 - Optimised slightly multi-job submission
507 - Optimised slightly opcode loading
508 - Backported the multi-job submit framework from the development
509 branch; multi-instance start and stop should be faster
510 - Added script to clean archived jobs after 21 days; this will reduce
511 the size of the queue directory
512 - Added some extra checks in disk size tracking
513 - Added an example ethers hook script
514 - Added a cluster parameter that prevents Ganeti from modifying of
516 - Added more node information to RAPI responses
517 - Added a ``gnt-job watch`` command that allows following the ouput of a
519 - Added a bind-address option to ganeti-rapi
520 - Added more checks to the configuration verify
521 - Enhanced the burnin script such that some operations can be retried
523 - Converted instance reinstall to multi-instance model
529 *(Released Fri, 7 Aug 2009)*
531 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
532 to allow using the pre-2.0.2 behaviour in activation, if any existing
533 instances have mismatched disk sizes in the configuration
534 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
535 any configuration mismatches for disk sizes
536 - Added ``gnt-master cluste-failover --no-voting`` to allow master
537 failover to work on two-node clusters
538 - Fixed the ``--net`` option of ``gnt-backup import``, which was
540 - Fixed detection of OS script errors in ``gnt-backup export``
541 - Fixed exit code of ``gnt-backup export``
547 *(Released Fri, 17 Jul 2009)*
549 - Added experimental support for stripped logical volumes; this should
550 enhance performance but comes with a higher complexity in the block
551 device handling; stripping is only enabled when passing
552 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
553 affected even in the non-stripped mode
554 - Improved resiliency against transient failures at the end of DRBD
555 resyncs, and in general of DRBD resync checks
556 - Fixed a couple of issues with exports and snapshot errors
557 - Fixed a couple of issues in instance listing
558 - Added display of the disk size in ``gnt-instance info``
559 - Fixed checking for valid OSes in instance creation
560 - Fixed handling of the "vcpus" parameter in instance listing and in
561 general of invalid parameters
562 - Fixed http server library, and thus RAPI, to handle invalid
563 username/password combinations correctly; this means that now they
564 report unauthorized for queries too, not only for modifications,
565 allowing earlier detect of configuration problems
566 - Added a new "role" node list field, equivalent to the master/master
567 candidate/drained/offline flags combinations
568 - Fixed cluster modify and changes of candidate pool size
569 - Fixed cluster verify error messages for wrong files on regular nodes
570 - Fixed a couple of issues with node demotion from master candidate role
571 - Fixed node readd issues
572 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
573 - Added a new ``--no-voting`` option for masterfailover to fix failover
574 on two-nodes clusters when the former master node is unreachable
575 - Added instance reinstall over RAPI
581 *(Released Tue, 16 Jun 2009)*
583 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
584 allow re-adding the start in single-user option (regression from 1.2)
585 - the watcher writes the instance status to a file, to allow monitoring
586 to report the instance status (from the master) based on cached
587 results of the watcher's queries; while this can get stale if the
588 watcher is being locked due to other work on the cluster, this is
590 - the watcher now also restarts the node daemon and the rapi daemon if
592 - fixed the watcher to handle full and drained queue cases
593 - hooks export more instance data in the environment, which helps if
594 hook scripts need to take action based on the instance's properties
595 (no longer need to query back into ganeti)
596 - instance failovers when the instance is stopped do not check for free
597 RAM, so that failing over a stopped instance is possible in low memory
599 - rapi uses queries for tags instead of jobs (for less job traffic), and
600 for cluster tags it won't talk to masterd at all but read them from
602 - a couple of error handling fixes in RAPI
603 - drbd handling: improved the error handling of inconsistent disks after
604 resync to reduce the frequency of "there are some degraded disks for
605 this instance" messages
606 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
607 error handling path called a wrong function name)
613 *(Released Wed, 27 May 2009)*
615 - no changes from rc5
618 Version 2.0 release candidate 5
619 -------------------------------
621 *(Released Wed, 20 May 2009)*
623 - fix a couple of bugs (validation, argument checks)
624 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
625 - some small improvements to RAPI and IAllocator
626 - make watcher automatically start the master daemon if down
629 Version 2.0 release candidate 4
630 -------------------------------
632 *(Released Mon, 27 Apr 2009)*
634 - change the OS list to not require locks; this helps with big clusters
635 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
636 volume group is broken
637 - ``gnt-instance info``, without any arguments, doesn't run for all
638 instances anymore; either pass ``--all`` or pass the desired
639 instances; this helps against mistakes on big clusters where listing
640 the information for all instances takes a long time
641 - miscellaneous doc and man pages fixes
644 Version 2.0 release candidate 3
645 -------------------------------
647 *(Released Wed, 8 Apr 2009)*
649 - Change the internal locking model of some ``gnt-node`` commands, in
650 order to reduce contention (and blocking of master daemon) when
651 batching many creation/reinstall jobs
652 - Fixes to Xen soft reboot
653 - No longer build documentation at build time, instead distribute it in
654 the archive, in order to reduce the need for the whole docbook/rst
658 Version 2.0 release candidate 2
659 -------------------------------
661 *(Released Fri, 27 Mar 2009)*
663 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
664 - Fix watcher startup sequence, improves the behaviour of busy clusters
665 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
666 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
667 bind address and other places
668 - Some documentation fixes and updates
671 Version 2.0 release candidate 1
672 -------------------------------
674 *(Released Mon, 2 Mar 2009)*
676 - More documentation updates, now all docs should be more-or-less
678 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
680 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
682 - Fix an issue related to $libdir/run/ganeti and cluster creation
688 *(Released Thu, 19 Feb 2009)*
690 - Xen PVM and KVM have switched the default value for the instance root
691 disk to the first partition on the first drive, instead of the whole
692 drive; this means that the OS installation scripts must be changed
694 - Man pages have been updated
695 - RAPI has been switched by default to HTTPS, and the exported functions
696 should all work correctly
697 - RAPI v1 has been removed
698 - Many improvements to the KVM hypervisor
699 - Block device errors are now better reported
700 - Many other bugfixes and small improvements
706 *(Released Mon, 26 Jan 2009)*
708 - Version 2 is a general rewrite of the code and therefore the
709 differences are too many to list, see the design document for 2.0 in
710 the ``doc/`` subdirectory for more details
711 - In this beta version there is not yet a migration path from 1.2 (there
712 will be one in the final 2.0 release)
713 - A few significant changes are:
715 - all commands are executed by a daemon (``ganeti-masterd``) and the
716 various ``gnt-*`` commands are just front-ends to it
717 - all the commands are entered into, and executed from a job queue,
718 see the ``gnt-job(8)`` manpage
719 - the RAPI daemon supports read-write operations, secured by basic
720 HTTP authentication on top of HTTPS
721 - DRBD version 0.7 support has been removed, DRBD 8 is the only
722 supported version (when migrating from Ganeti 1.2 to 2.0, you need
723 to migrate to DRBD 8 first while still running Ganeti 1.2)
724 - DRBD devices are using statically allocated minor numbers, which
725 will be assigned to existing instances during the migration process
726 - there is support for both Xen PVM and Xen HVM instances running on
728 - KVM virtualization is supported too
729 - file-based storage has been implemented, which means that it is
730 possible to run the cluster without LVM and DRBD storage, for
731 example using a shared filesystem exported from shared storage (and
732 still have live migration)
738 *(Released Tue, 13 Jan 2009)*
740 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
741 - Reuse the old instance mac address by default on instance import, if
742 the instance name is the same.
743 - Handle situations in which the node info rpc returns incomplete
745 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
746 - Improved version of batcher:
749 - instance mac address support
750 - support for HVM clusters/instances
752 - Add an option to show the number of cpu sockets and nodes in
754 - Support OSes that handle more than one version of the OS api (but do
755 not change the current API in any other way)
756 - Fix ``gnt-node migrate``
757 - ``gnt-debug`` man page
758 - Fixes various more typos and small issues
759 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
765 *(Released Wed, 24 Sep 2008)*
767 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
768 type of disk exported to fully virtualized instances.
769 - provide access to the serial console of HVM instances
770 - instance auto_balance flag, set by default. If turned off it will
771 avoid warnings on cluster verify if there is not enough memory to fail
772 over an instance. in the future it will prevent automatically failing
773 it over when we will support that.
774 - batcher tool for instance creation, see ``tools/README.batcher``
775 - ``gnt-instance reinstall --select-os`` to interactively select a new
776 operating system when reinstalling an instance.
777 - when changing the memory amount on instance modify a check has been
778 added that the instance will be able to start. also warnings are
779 emitted if the instance will not be able to fail over, if auto_balance
781 - documentation fixes
782 - sync fields between ``gnt-instance list/modify/add/import``
783 - fix a race condition in drbd when the sync speed was set after giving
784 the device a remote peer.
790 *(Released Tue, 22 Jul 2008)*
792 - note: the allowed size and number of tags per object were reduced
793 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
794 - fixed twisted 8.x compatibility
795 - fixed ``gnt-instance replace-disks`` with iallocator
796 - add TCP keepalives on twisted connections to detect restarted nodes
797 - disk increase support, see ``gnt-instance grow-disk``
798 - implement bulk node/instance query for RAPI
799 - add tags in node/instance listing (optional)
800 - experimental migration (and live migration) support, read the man page
801 for ``gnt-instance migrate``
802 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
803 has some small improvements in handling its state file
809 *(Released Fri, 13 Jun 2008)*
811 - Experimental readonly, REST-based remote API implementation;
812 automatically started on master node, TCP port 5080, if enabled by
813 ``--enable-rapi`` parameter to configure script.
814 - Instance allocator support. Add and import instance accept a
815 ``--iallocator`` parameter, and call that instance allocator to decide
816 which node to use for the instance. The iallocator document describes
817 what's expected from an allocator script.
818 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
819 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
820 node is lost there is still enough memory to fail over the instances
822 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
823 ``gnt-cluster verify``, to check for site-specific compliance. All the
824 hooks will run, and their output, if any, will be displayed. Any
825 failing hook will make the verification return an error value.
826 - ``gnt-cluster verify`` now checks that its peers are reachable on the
827 primary and secondary interfaces
828 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
829 that is still declared as part of the cluster and has failed.
830 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
831 specifying output fields, that just adds the chosen fields to the
833 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
834 export from the filesystem.
835 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
836 have been added. Using them you can enable/disable acpi and pae
837 support, and specify a path for a cd image to be exported to the
838 instance. These parameters as the name suggest only work on HVM
840 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
841 PAE support will be set to the previously hardcoded values, but the
842 (previously hardcoded) path to the CDROM ISO image will be unset and
843 if required, needs to be set manually with ``gnt-instance modify``
845 - The address to which an instance's VNC console is bound is now
846 selectable per-instance, rather than being cluster wide. Of course
847 this only applies to instances controlled via VNC, so currently just
848 applies to HVM clusters.
854 *(Released Mon, 18 Feb 2008)*
856 - more tweaks to the disk activation code (especially helpful for DRBD)
857 - change the default ``gnt-instance list`` output format, now there is
858 one combined status field (see the manpage for the exact values this
860 - some more fixes for the mac export to hooks change
861 - make Ganeti not break with DRBD 8.2.x (which changed the version
862 format in ``/proc/drbd``) (issue 24)
863 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
864 template, allowing migration from DRBD0.7+MD to DRBD8
870 *(Released Wed, 30 Jan 2008)*
872 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
874 - add command aliases infrastructure and a few aliases
875 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
876 man pages and the ``--help`` option of ``gnt-node
877 list``/``gnt-instance list``
878 - fix ``gnt-backup list`` with down nodes (issue 21)
879 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
880 - fix the dist archive and add a check for including svn/git files in
882 - some developer-related changes: improve the burnin and the QA suite,
883 add an upload script for testing during development
889 *(Released Wed, 16 Jan 2008)*
891 - experimental HVM support, read the install document, section
892 "Initializing the cluster"
893 - allow for the PVM hypervisor per-instance kernel and initrd paths
894 - add a new command ``gnt-cluster verify-disks`` which uses a new
895 algorithm to improve the reconnection of the DRBD pairs if the device
896 on the secondary node has gone away
897 - make logical volume code auto-activate LVs at disk activation time
898 - slightly improve the speed of activating disks
899 - allow specification of the MAC address at instance creation time, and
900 changing it later via ``gnt-instance modify``
901 - fix handling of external commands that generate lots of output on
903 - update documentation with regard to minimum version of DRBD8 supported
909 *(Released Tue, 4 Dec 2007)*
911 - Log the ``xm create`` output to the node daemon log on failure (to
912 help diagnosing the error)
913 - In debug mode, log all external commands output if failed to the logs
914 - Change parsing of lvm commands to ignore stderr
920 *(Released Wed, 28 Nov 2007)*
922 - Another round of updates to the DRBD 8 code to deal with more failures
923 in the replace secondary node operation
924 - Some more logging of failures in disk operations (lvm, drbd)
925 - A few documentation updates
932 *(Released Tue, 13 Nov 2007)*
934 - Change configuration file format from Python's Pickle to JSON.
935 Upgrading is possible using the cfgupgrade utility.
936 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
937 faster replace disks and is more stable (DRBD 8 has many improvements
938 compared to DRBD 0.7)
939 - Added command line tags support (see man pages for ``gnt-instance``,
940 ``gnt-node``, ``gnt-cluster``)
941 - Added instance rename support
942 - Added multi-instance startup/shutdown
943 - Added cluster rename support
944 - Added ``gnt-node evacuate`` to simplify some node operations
945 - Added instance reboot operation that can speedup reboot as compared to
947 - Soften the requirement that hostnames are in FQDN format
948 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
950 - Removed dependency on debian's patched fping that uses the
951 non-standard ``-S`` option
952 - Now the OS definitions are searched for in multiple, configurable
953 paths (easier for distros to package)
954 - Some changes to the hooks infrastructure (especially the new
955 post-configuration update hook)
956 - Other small bugfixes
