8 *(Released Fri, 12 Mar 2010)*
10 During the 2.1.0 long release candidate cycle, a lot of improvements and
11 changes have accumulated with were released later as 2.1.1.
16 The node evacuate command (``gnt-node evacuate``) was significantly
17 rewritten, and as such the IAllocator protocol was changed - a new
18 request type has been added. This unfortunate change during a stable
19 series is designed to improve performance of node evacuations; on
20 clusters with more than about five nodes and which are well-balanced,
21 evacuation should proceed in parallel for all instances of the node
22 being evacuated. As such, any existing IAllocator scripts need to be
23 updated, otherwise the above command will fail due to the unknown
24 request. The provided "dumb" allocator has not been updated; but the
25 ganeti-htools package supports the new protocol since version 0.2.4.
27 Another important change is increased validation of node and instance
28 names. This might create problems in special cases, if invalid host
31 Also, a new layer of hypervisor parameters has been added, that sits at
32 OS level between the cluster defaults and the instance ones. This allows
33 customisation of virtualization parameters depending on the installed
34 OS. For example instances with OS 'X' may have a different KVM kernel
35 (or any other parameter) than the cluster defaults. This is intended to
36 help managing a multiple OSes on the same cluster, without manual
37 modification of each instance's parameters.
39 A tool for merging clusters, ``cluster-merge``, has been added in the
45 - Improved the int/float conversions that should make the code more
46 robust in face of errors from the node daemons
47 - Fixed the remove node code in case of internal configuration errors
48 - Fixed the node daemon behaviour in face of inconsistent queue
49 directory (e.g. read-only file-system where we can't open the files
51 - Fixed the behaviour of gnt-node modify for master candidate demotion;
52 now it either aborts cleanly or, if given the new “auto_promote”
53 parameter, will automatically promote other nodes as needed
54 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
55 completely prevent Ganeti from working
56 - Fixed bug for instance export when not all disks were successfully
58 - Fixed behaviour of node add when the new node is slow in starting up
60 - Fixed handling of signals in the LUXI client, which should improve
61 behaviour of command-line scripts
62 - Added checks for invalid node/instance names in the configuration (now
63 flagged during cluster verify)
64 - Fixed watcher behaviour for disk activation errors
65 - Fixed two potentially endless loops in http library, which led to the
66 RAPI daemon hanging and consuming 100% CPU in some cases
67 - Fixed bug in RAPI daemon related to hashed passwords
68 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
70 - Enhanced compatibility with non-Debian OSes, but not using absolute
71 path in some commands and allowing customisation of the ssh
72 configuration directory
73 - Fixed possible future issue with new Python versions by abiding to the
74 proper use of ``__slots__`` attribute on classes
75 - Added checks that should prevent directory traversal attacks
76 - Many documentation fixes based on feedback from users
81 - Added an “early_release” more for instance replace disks and node
82 evacuate, where we release locks earlier and thus allow higher
83 parallelism within the cluster
84 - Added watcher hooks, intended to allow the watcher to restart other
85 daemons (e.g. from the ganeti-nbma project), but they can be used of
86 course for any other purpose
87 - Added a compile-time disable for DRBD barriers, to increase
88 performance if the administrator trusts the power supply or the
89 storage system to not lose writes
90 - Added the option of using syslog for logging instead of, or in
91 addition to, Ganeti's own log files
92 - Removed boot restriction for paravirtual NICs for KVM, recent versions
93 can indeed boot from a paravirtual NIC
94 - Added a generic debug level for many operations; while this is not
95 used widely yet, it allows one to pass the debug value all the way to
97 - Enhanced the hooks environment for instance moves (failovers,
98 migrations) where the primary/secondary nodes changed during the
99 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
100 - Enhanced data validations for many user-supplied values; one important
101 item is the restrictions imposed on instance and node names, which
102 might reject some (invalid) host names
103 - Add a configure-time option to disable file-based storage, if it's not
104 needed; this allows greater security separation between the master
105 node and the other nodes from the point of view of the inter-node RPC
107 - Added user notification in interactive tools if job is waiting in the
108 job queue or trying to acquire locks
109 - Added log messages when a job is waiting for locks
110 - Added filtering by node tags in instance operations which admit
111 multiple instances (start, stop, reboot, reinstall)
112 - Added a new tool for cluster mergers, ``cluster-merge``
113 - Parameters from command line which are of the form ``a=b,c=d`` can now
114 use backslash escapes to pass in values which contain commas,
115 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
117 - For KVM, the instance name is the first parameter passed to KVM, so
118 that it's more visible in the process list
124 *(Released Tue, 2 Mar 2010)*
126 Ganeti 2.1 brings many improvements with it. Major changes:
128 - Added infrastructure to ease automated disk repairs
129 - Added new daemon to export configuration data in a cheaper way than
131 - Instance NICs can now be routed instead of being associated with a
133 - Improved job locking logic to reduce impact of jobs acquiring multiple
134 locks waiting for other long-running jobs
136 In-depth implementation details can be found in the Ganeti 2.1 design
142 - Added chroot hypervisor
143 - Added more options to xen-hvm hypervisor (``kernel_path`` and
145 - Added more options to xen-pvm hypervisor (``use_bootloader``,
146 ``bootloader_path`` and ``bootloader_args``)
147 - Added the ``use_localtime`` option for the xen-hvm and kvm
148 hypervisors, and the default value for this has changed to false (in
149 2.0 xen-hvm always enabled it)
150 - Added luxi call to submit multiple jobs in one go
151 - Added cluster initialization option to not modify ``/etc/hosts``
153 - Added network interface parameters

162 - ``/2/nodes/[node_name]/storage``
163 - ``/2/nodes/[node_name]/storage/modify``
164 - ``/2/nodes/[node_name]/storage/repair``
166 - Added OpCodes to evacuate or migrate all instances on a node
167 - Added new command to list storage elements on nodes (``gnt-node
168 list-storage``) and modify them (``gnt-node modify-storage``)
169 - Added new ssconf files with master candidate IP address
170 (``ssconf_master_candidates_ips``), node primary IP address
171 (``ssconf_node_primary_ips``) and node secondary IP address
172 (``ssconf_node_secondary_ips``)
173 - Added ``ganeti-confd`` and a client library to query the Ganeti
174 configuration via UDP
175 - Added ability to run hooks after cluster initialization and before

189 ``--verbose`` to restore previous behaviour)
190 - Added UUIDs to the main config entities (cluster, nodes, instances)
191 - Added support for OS variants
192 - Added support for hashed passwords in the Ganeti remote API users file
194 - Added option to specify maximum timeout on instance shutdown
195 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
196 - Added new helper script to start and stop Ganeti daemons
197 (``daemon-util``), with the intent to reduce the work necessary to
198 adjust Ganeti for non-Debian distributions and to start/stop daemons
200 - Added more unittests
201 - Fixed critical bug in ganeti-masterd startup
202 - Removed the configure-time ``kvm-migration-port`` parameter, this is
203 now customisable at the cluster level for both the KVM and Xen
204 hypervisors using the new ``migration_port`` parameter
205 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
206 reinstalling an instance

228 - Fix a string formatting bug
229 - Improve safety of the code in some error paths
230 - Improve data validation in the master of values returned from nodes
236 *(Released Thu, 17 Dec 2009)*
238 - Fix security issue due to missing validation of iallocator names; this
239 allows local and remote execution of arbitrary executables
240 - Fix failure of gnt-node list during instance removal
241 - Ship the RAPI documentation in the archive
247 *(Released Wed, 30 Sep 2009)*
249 - Fixed many wrong messages

251 - Fixed MAC checking at instance creation time
252 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
253 - Fixed a few issues related to signal handling in both daemons and
255 - Fixed the example startup script provided
256 - Fixed insserv dependencies in the example startup script (patch from
258 - Fixed handling of drained nodes in the iallocator framework
259 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
261 - Fixed error related to invalid job IDs in job polling
262 - Fixed job/opcode persistence on unclean master shutdown
263 - Fixed handling of partial job processing after unclean master
265 - Fixed error reporting from LUs, previously all errors were converted

267 - Fixed error reporting from burnin
268 - Decreased significantly the memory usage of the job queue
269 - Optimised slightly multi-job submission
270 - Optimised slightly opcode loading
271 - Backported the multi-job submit framework from the development
272 branch; multi-instance start and stop should be faster
273 - Added script to clean archived jobs after 21 days; this will reduce
274 the size of the queue directory
275 - Added some extra checks in disk size tracking
276 - Added an example ethers hook script
277 - Added a cluster parameter that prevents Ganeti from modifying of
279 - Added more node information to RAPI responses
280 - Added a ``gnt-job watch`` command that allows following the ouput of a
282 - Added a bind-address option to ganeti-rapi
283 - Added more checks to the configuration verify
284 - Enhanced the burnin script such that some operations can be retried
286 - Converted instance reinstall to multi-instance model
292 *(Released Fri, 7 Aug 2009)*
294 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
295 to allow using the pre-2.0.2 behaviour in activation, if any existing
296 instances have mismatched disk sizes in the configuration
297 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
298 any configuration mismatches for disk sizes
299 - Added ``gnt-master cluste-failover --no-voting`` to allow master
300 failover to work on two-node clusters
301 - Fixed the ``--net`` option of ``gnt-backup import``, which was
303 - Fixed detection of OS script errors in ``gnt-backup export``
304 - Fixed exit code of ``gnt-backup export``
310 *(Released Fri, 17 Jul 2009)*
312 - Added experimental support for stripped logical volumes; this should
313 enhance performance but comes with a higher complexity in the block
314 device handling; stripping is only enabled when passing
315 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
316 affected even in the non-stripped mode
317 - Improved resiliency against transient failures at the end of DRBD
318 resyncs, and in general of DRBD resync checks
319 - Fixed a couple of issues with exports and snapshot errors
320 - Fixed a couple of issues in instance listing
321 - Added display of the disk size in ``gnt-instance info``
322 - Fixed checking for valid OSes in instance creation
323 - Fixed handling of the "vcpus" parameter in instance listing and in
324 general of invalid parameters
325 - Fixed http server library, and thus RAPI, to handle invalid
326 username/password combinations correctly; this means that now they
327 report unauthorized for queries too, not only for modifications,
328 allowing earlier detect of configuration problems
329 - Added a new "role" node list field, equivalent to the master/master
330 candidate/drained/offline flags combinations
331 - Fixed cluster modify and changes of candidate pool size
332 - Fixed cluster verify error messages for wrong files on regular nodes
333 - Fixed a couple of issues with node demotion from master candidate role
334 - Fixed node readd issues
335 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
336 - Added a new ``--no-voting`` option for masterfailover to fix failover
337 on two-nodes clusters when the former master node is unreachable
338 - Added instance reinstall over RAPI
344 *(Released Tue, 16 Jun 2009)*
346 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
347 allow re-adding the start in single-user option (regression from 1.2)
348 - the watcher writes the instance status to a file, to allow monitoring
349 to report the instance status (from the master) based on cached
350 results of the watcher's queries; while this can get stale if the
351 watcher is being locked due to other work on the cluster, this is
353 - the watcher now also restarts the node daemon and the rapi daemon if
355 - fixed the watcher to handle full and drained queue cases
356 - hooks export more instance data in the environment, which helps if
357 hook scripts need to take action based on the instance's properties
358 (no longer need to query back into ganeti)
359 - instance failovers when the instance is stopped do not check for free
360 RAM, so that failing over a stopped instance is possible in low memory
362 - rapi uses queries for tags instead of jobs (for less job traffic), and
363 for cluster tags it won't talk to masterd at all but read them from
365 - a couple of error handling fixes in RAPI
366 - drbd handling: improved the error handling of inconsistent disks after
367 resync to reduce the frequency of "there are some degraded disks for
368 this instance" messages
369 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
370 error handling path called a wrong function name)
376 *(Released Wed, 27 May 2009)*
378 - no changes from rc5
381 Version 2.0 release candidate 5
382 -------------------------------
384 *(Released Wed, 20 May 2009)*
386 - fix a couple of bugs (validation, argument checks)
387 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
388 - some small improvements to RAPI and IAllocator

392 Version 2.0 release candidate 4
393 -------------------------------
395 *(Released Mon, 27 Apr 2009)*
397 - change the OS list to not require locks; this helps with big clusters
398 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
399 volume group is broken
400 - ``gnt-instance info``, without any arguments, doesn't run for all
401 instances anymore; either pass ``--all`` or pass the desired
402 instances; this helps against mistakes on big clusters where listing
403 the information for all instances takes a long time
404 - miscellaneous doc and man pages fixes
407 Version 2.0 release candidate 3
408 -------------------------------
410 *(Released Wed, 8 Apr 2009)*
412 - Change the internal locking model of some ``gnt-node`` commands, in
413 order to reduce contention (and blocking of master daemon) when
414 batching many creation/reinstall jobs
415 - Fixes to Xen soft reboot
416 - No longer build documentation at build time, instead distribute it in
417 the archive, in order to reduce the need for the whole docbook/rst
421 Version 2.0 release candidate 2
422 -------------------------------
424 *(Released Fri, 27 Mar 2009)*
426 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
427 - Fix watcher startup sequence, improves the behaviour of busy clusters
428 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
429 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
430 bind address and other places
431 - Some documentation fixes and updates
434 Version 2.0 release candidate 1
435 -------------------------------
437 *(Released Mon, 2 Mar 2009)*
439 - More documentation updates, now all docs should be more-or-less
441 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
443 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
445 - Fix an issue related to $libdir/run/ganeti and cluster creation
451 *(Released Thu, 19 Feb 2009)*
453 - Xen PVM and KVM have switched the default value for the instance root
454 disk to the first partition on the first drive, instead of the whole
455 drive; this means that the OS installation scripts must be changed
457 - Man pages have been updated
458 - RAPI has been switched by default to HTTPS, and the exported functions
459 should all work correctly
460 - RAPI v1 has been removed
461 - Many improvements to the KVM hypervisor
462 - Block device errors are now better reported
463 - Many other bugfixes and small improvements
469 *(Released Mon, 26 Jan 2009)*
471 - Version 2 is a general rewrite of the code and therefore the
472 differences are too many to list, see the design document for 2.0 in
473 the ``doc/`` subdirectory for more details
474 - In this beta version there is not yet a migration path from 1.2 (there
475 will be one in the final 2.0 release)
476 - A few significant changes are:
478 - all commands are executed by a daemon (``ganeti-masterd``) and the
479 various ``gnt-*`` commands are just front-ends to it
480 - all the commands are entered into, and executed from a job queue,
481 see the ``gnt-job(8)`` manpage
482 - the RAPI daemon supports read-write operations, secured by basic
483 HTTP authentication on top of HTTPS
484 - DRBD version 0.7 support has been removed, DRBD 8 is the only
485 supported version (when migrating from Ganeti 1.2 to 2.0, you need
486 to migrate to DRBD 8 first while still running Ganeti 1.2)
487 - DRBD devices are using statically allocated minor numbers, which
488 will be assigned to existing instances during the migration process
489 - there is support for both Xen PVM and Xen HVM instances running on
491 - KVM virtualization is supported too
492 - file-based storage has been implemented, which means that it is
493 possible to run the cluster without LVM and DRBD storage, for
494 example using a shared filesystem exported from shared storage (and
495 still have live migration)
501 *(Released Tue, 13 Jan 2009)*
503 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
504 - Reuse the old instance mac address by default on instance import, if
505 the instance name is the same.
506 - Handle situations in which the node info rpc returns incomplete
508 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
509 - Improved version of batcher:
512 - instance mac address support
513 - support for HVM clusters/instances
515 - Add an option to show the number of cpu sockets and nodes in
517 - Support OSes that handle more than one version of the OS api (but do
518 not change the current API in any other way)
519 - Fix ``gnt-node migrate``
520 - ``gnt-debug`` man page
521 - Fixes various more typos and small issues
522 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
528 *(Released Wed, 24 Sep 2008)*
530 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
531 type of disk exported to fully virtualized instances.
532 - provide access to the serial console of HVM instances
533 - instance auto_balance flag, set by default. If turned off it will
534 avoid warnings on cluster verify if there is not enough memory to fail
535 over an instance. in the future it will prevent automatically failing
536 it over when we will support that.
537 - batcher tool for instance creation, see ``tools/README.batcher``
538 - ``gnt-instance reinstall --select-os`` to interactively select a new
539 operating system when reinstalling an instance.
540 - when changing the memory amount on instance modify a check has been
541 added that the instance will be able to start. also warnings are
542 emitted if the instance will not be able to fail over, if auto_balance
544 - documentation fixes
545 - sync fields between ``gnt-instance list/modify/add/import``
546 - fix a race condition in drbd when the sync speed was set after giving
547 the device a remote peer.
553 *(Released Tue, 22 Jul 2008)*
555 - note: the allowed size and number of tags per object were reduced
556 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
557 - fixed twisted 8.x compatibility
558 - fixed ``gnt-instance replace-disks`` with iallocator
559 - add TCP keepalives on twisted connections to detect restarted nodes
560 - disk increase support, see ``gnt-instance grow-disk``
561 - implement bulk node/instance query for RAPI
562 - add tags in node/instance listing (optional)
563 - experimental migration (and live migration) support, read the man page
564 for ``gnt-instance migrate``
565 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
566 has some small improvements in handling its state file
572 *(Released Fri, 13 Jun 2008)*
574 - Experimental readonly, REST-based remote API implementation;
575 automatically started on master node, TCP port 5080, if enabled by
576 ``--enable-rapi`` parameter to configure script.
577 - Instance allocator support. Add and import instance accept a
578 ``--iallocator`` parameter, and call that instance allocator to decide
579 which node to use for the instance. The iallocator document describes
580 what's expected from an allocator script.
581 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
582 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
583 node is lost there is still enough memory to fail over the instances
585 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
586 ``gnt-cluster verify``, to check for site-specific compliance. All the
587 hooks will run, and their output, if any, will be displayed. Any
588 failing hook will make the verification return an error value.
589 - ``gnt-cluster verify`` now checks that its peers are reachable on the
590 primary and secondary interfaces
591 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
592 that is still declared as part of the cluster and has failed.
593 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
594 specifying output fields, that just adds the chosen fields to the
596 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
597 export from the filesystem.
598 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
599 have been added. Using them you can enable/disable acpi and pae
600 support, and specify a path for a cd image to be exported to the
601 instance. These parameters as the name suggest only work on HVM
603 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
604 PAE support will be set to the previously hardcoded values, but the
605 (previously hardcoded) path to the CDROM ISO image will be unset and
606 if required, needs to be set manually with ``gnt-instance modify``
608 - The address to which an instance's VNC console is bound is now
609 selectable per-instance, rather than being cluster wide. Of course
610 this only applies to instances controlled via VNC, so currently just
611 applies to HVM clusters.
617 *(Released Mon, 18 Feb 2008)*
619 - more tweaks to the disk activation code (especially helpful for DRBD)
620 - change the default ``gnt-instance list`` output format, now there is
621 one combined status field (see the manpage for the exact values this
623 - some more fixes for the mac export to hooks change
624 - make Ganeti not break with DRBD 8.2.x (which changed the version
625 format in ``/proc/drbd``) (issue 24)
626 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
627 template, allowing migration from DRBD0.7+MD to DRBD8
633 *(Released Wed, 30 Jan 2008)*
635 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
637 - add command aliases infrastructure and a few aliases
638 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
639 man pages and the ``--help`` option of ``gnt-node
640 list``/``gnt-instance list``
641 - fix ``gnt-backup list`` with down nodes (issue 21)
642 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
643 - fix the dist archive and add a check for including svn/git files in
645 - some developer-related changes: improve the burnin and the QA suite,
646 add an upload script for testing during development
652 *(Released Wed, 16 Jan 2008)*
654 - experimental HVM support, read the install document, section
655 "Initializing the cluster"
656 - allow for the PVM hypervisor per-instance kernel and initrd paths
657 - add a new command ``gnt-cluster verify-disks`` which uses a new
658 algorithm to improve the reconnection of the DRBD pairs if the device
659 on the secondary node has gone away
660 - make logical volume code auto-activate LVs at disk activation time
661 - slightly improve the speed of activating disks
662 - allow specification of the MAC address at instance creation time, and
663 changing it later via ``gnt-instance modify``
664 - fix handling of external commands that generate lots of output on
666 - update documentation with regard to minimum version of DRBD8 supported
672 *(Released Tue, 4 Dec 2007)*
674 - Log the ``xm create`` output to the node daemon log on failure (to
675 help diagnosing the error)
676 - In debug mode, log all external commands output if failed to the logs
677 - Change parsing of lvm commands to ignore stderr
683 *(Released Wed, 28 Nov 2007)*
685 - Another round of updates to the DRBD 8 code to deal with more failures
686 in the replace secondary node operation
687 - Some more logging of failures in disk operations (lvm, drbd)
688 - A few documentation updates
695 *(Released Tue, 13 Nov 2007)*
697 - Change configuration file format from Python's Pickle to JSON.
698 Upgrading is possible using the cfgupgrade utility.
699 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
700 faster replace disks and is more stable (DRBD 8 has many improvements
701 compared to DRBD 0.7)
702 - Added command line tags support (see man pages for ``gnt-instance``,
703 ``gnt-node``, ``gnt-cluster``)
704 - Added instance rename support
705 - Added multi-instance startup/shutdown
706 - Added cluster rename support
707 - Added ``gnt-node evacuate`` to simplify some node operations
708 - Added instance reboot operation that can speedup reboot as compared to
710 - Soften the requirement that hostnames are in FQDN format
711 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
713 - Removed dependency on debian's patched fping that uses the
714 non-standard ``-S`` option
715 - Now the OS definitions are searched for in multiple, configurable
716 paths (easier for distros to package)
717 - Some changes to the hooks infrastructure (especially the new
718 post-configuration update hook)
719 - Other small bugfixes
