6 - Fixed many wrong messages
7 - Fixed a few bugs related to the locking library
8 - Fixed MAC checking at instance creation time
9 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
10 - Fixed a few issues related to signal handling in both daemons and
12 - Fixed the example startup script provided
13 - Fixed insserv dependencies in the example startup script (patch from
15 - Fixed handling of drained nodes in the iallocator framework
16 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
18 - Fixed error related to invalid job IDs in job polling
19 - Fixed job/opcode persistence on unclean master shutdown
20 - Fixed handling of partial job processing after unclean master
22 - Fixed error reporting from LUs, previously all errors were converted
24 - Fixed error reporting from burnin
25 - Decreased significantly the memory usage of the job queue
26 - Optimised slightly multi-job submission
27 - Optimised slightly opcode loading
28 - Backported the multi-job submit framework from the development
29 branch; multi-instance start and stop should be faster
30 - Added script to clean archived jobs after 21 days; this will reduce
31 the size of the queue directory
32 - Added some extra checks in disk size tracking
33 - Added an example ethers hook script
34 - Added a cluster parameter that prevents Ganeti from modifying of
36 - Added more node information to RAPI responses
37 - Added a “gnt-job watch” command that allows following the ouput of a
39 - Added a bind-address option to ganeti-rapi
40 - Added more checks to the configuration verify
41 - Enhanced the burnin script such that some operations can be retried
43 - Converted instance reinstall to multi-instance model
48 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
49 to allow using the pre-2.0.2 behaviour in activation, if any existing
50 instances have mismatched disk sizes in the configuration
51 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
52 any configuration mismatches for disk sizes
53 - Added ``gnt-master cluste-failover --no-voting`` to allow master
54 failover to work on two-node clusters
55 - Fixed the ‘--net’ option of ``gnt-backup import``, which was unusable
56 - Fixed detection of OS script errors in ``gnt-backup export``
57 - Fixed exit code of ``gnt-backup export``
63 - Added experimental support for stripped logical volumes; this should
64 enhance performance but comes with a higher complexity in the block
65 device handling; stripping is only enabled when passing
66 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
67 affected even in the non-stripped mode
68 - Improved resiliency against transient failures at the end of DRBD
69 resyncs, and in general of DRBD resync checks
70 - Fixed a couple of issues with exports and snapshot errors
71 - Fixed a couple of issues in instance listing
72 - Added display of the disk size in ``gnt-instance info``
73 - Fixed checking for valid OSes in instance creation
74 - Fixed handling of the ‘vcpus’ parameter in instance listing and in
75 general of invalid parameters
76 - Fixed http server library, and thus RAPI, to handle invalid
77 username/password combinations correctly; this means that now they
78 report unauthorized for queries too, not only for modifications,
79 allowing earlier detect of configuration problems
80 - Added a new ‘role’ node list field, equivalent to the master/master
81 candidate/drained/offline flags combinations
82 - Fixed cluster modify and changes of candidate pool size
83 - Fixed cluster verify error messages for wrong files on regular nodes
84 - Fixed a couple of issues with node demotion from master candidate role
85 - Fixed node readd issues
86 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
87 - Added a new ‘--no-voting’ option for masterfailover to fix failover on
88 two-nodes clusters when the former master node is unreachable
89 - Added instance reinstall over RAPI
95 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
96 allow re-adding the start in single-user option (regression from 1.2)
97 - the watcher writes the instance status to a file, to allow monitoring
98 to report the instance status (from the master) based on cached
99 results of the watcher's queries; while this can get stale if the
100 watcher is being locked due to other work on the cluster, this is
102 - the watcher now also restarts the node daemon and the rapi daemon if
104 - fixed the watcher to handle full and drained queue cases
105 - hooks export more instance data in the environment, which helps if
106 hook scripts need to take action based on the instance's properties
107 (no longer need to query back into ganeti)
108 - instance failovers when the instance is stopped do not check for free
109 RAM, so that failing over a stopped instance is possible in low memory
111 - rapi uses queries for tags instead of jobs (for less job traffic), and
112 for cluster tags it won't talk to masterd at all but read them from
114 - a couple of error handling fixes in RAPI
115 - drbd handling: improved the error handling of inconsistent disks after
116 resync to reduce the frequency of "there are some degraded disks for
117 this instance" messages
118 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
119 error handling path called a wrong function name)
125 - no changes from rc5
128 Version 2.0 release candidate 5
129 -------------------------------
131 - fix a couple of bugs (validation, argument checks)
132 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
133 - some small improvements to RAPI and IAllocator
134 - make watcher automatically start the master daemon if down
137 Version 2.0 release candidate 4
138 -------------------------------
140 - change the OS list to not require locks; this helps with big clusters
141 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
142 volume group is broken
143 - ``gnt-instance info``, without any arguments, doesn't run for all
144 instances anymore; either pass ``--all`` or pass the desired
145 instances; this helps against mistakes on big clusters where listing
146 the information for all instances takes a long time
147 - miscellaneous doc and man pages fixes
150 Version 2.0 release candidate 3
151 -------------------------------
153 - Change the internal locking model of some ``gnt-node`` commands, in
154 order to reduce contention (and blocking of master daemon) when
155 batching many creation/reinstall jobs
156 - Fixes to Xen soft reboot
157 - No longer build documentation at build time, instead distribute it in
158 the archive, in order to reduce the need for the whole docbook/rst
162 Version 2.0 release candidate 2
163 -------------------------------
165 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
166 - Fix watcher startup sequence, improves the behaviour of busy clusters
167 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
168 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
169 bind address and other places
170 - Some documentation fixes and updates
173 Version 2.0 release candidate 1
174 -------------------------------
176 - More documentation updates, now all docs should be more-or-less
178 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
180 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
182 - Fix an issue related to $libdir/run/ganeti and cluster creation
188 - Xen PVM and KVM have switched the default value for the instance root
189 disk to the first partition on the first drive, instead of the whole
190 drive; this means that the OS installation scripts must be changed
192 - Man pages have been updated
193 - RAPI has been switched by default to HTTPS, and the exported functions
194 should all work correctly
195 - RAPI v1 has been removed
196 - Many improvements to the KVM hypervisor
197 - Block device errors are now better reported
198 - Many other bugfixes and small improvements
204 - Version 2 is a general rewrite of the code and therefore the
205 differences are too many to list, see the design document for 2.0 in
206 the ``doc/`` subdirectory for more details
207 - In this beta version there is not yet a migration path from 1.2 (there
208 will be one in the final 2.0 release)
209 - A few significant changes are:
211 - all commands are executed by a daemon (``ganeti-masterd``) and the
212 various ``gnt-*`` commands are just front-ends to it
213 - all the commands are entered into, and executed from a job queue,
214 see the ``gnt-job(8)`` manpage
215 - the RAPI daemon supports read-write operations, secured by basic
216 HTTP authentication on top of HTTPS
217 - DRBD version 0.7 support has been removed, DRBD 8 is the only
218 supported version (when migrating from Ganeti 1.2 to 2.0, you need
219 to migrate to DRBD 8 first while still running Ganeti 1.2)
220 - DRBD devices are using statically allocated minor numbers, which
221 will be assigned to existing instances during the migration process
222 - there is support for both Xen PVM and Xen HVM instances running on
224 - KVM virtualization is supported too
225 - file-based storage has been implemented, which means that it is
226 possible to run the cluster without LVM and DRBD storage, for
227 example using a shared filesystem exported from shared storage (and
228 still have live migration)
234 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
235 - Reuse the old instance mac address by default on instance import, if
236 the instance name is the same.
237 - Handle situations in which the node info rpc returns incomplete
239 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
240 - Improved version of batcher:
243 - instance mac address support
244 - support for HVM clusters/instances
246 - Add an option to show the number of cpu sockets and nodes in
248 - Support OSes that handle more than one version of the OS api (but do
249 not change the current API in any other way)
250 - Fix ``gnt-node migrate``
251 - ``gnt-debug`` man page
252 - Fixes various more typos and small issues
253 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
259 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
260 type of disk exported to fully virtualized instances.
261 - provide access to the serial console of HVM instances
262 - instance auto_balance flag, set by default. If turned off it will
263 avoid warnings on cluster verify if there is not enough memory to fail
264 over an instance. in the future it will prevent automatically failing
265 it over when we will support that.
266 - batcher tool for instance creation, see ``tools/README.batcher``
267 - ``gnt-instance reinstall --select-os`` to interactively select a new
268 operating system when reinstalling an instance.
269 - when changing the memory amount on instance modify a check has been
270 added that the instance will be able to start. also warnings are
271 emitted if the instance will not be able to fail over, if auto_balance
273 - documentation fixes
274 - sync fields between ``gnt-instance list/modify/add/import``
275 - fix a race condition in drbd when the sync speed was set after giving
276 the device a remote peer.
282 - note: the allowed size and number of tags per object were reduced
283 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
284 - fixed twisted 8.x compatibility
285 - fixed ``gnt-instance replace-disks`` with iallocator
286 - add TCP keepalives on twisted connections to detect restarted nodes
287 - disk increase support, see ``gnt-instance grow-disk``
288 - implement bulk node/instance query for RAPI
289 - add tags in node/instance listing (optional)
290 - experimental migration (and live migration) support, read the man page
291 for ``gnt-instance migrate``
292 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
293 has some small improvements in handling its state file
299 - Experimental readonly, REST-based remote API implementation;
300 automatically started on master node, TCP port 5080, if enabled by
301 ``--enable-rapi`` parameter to configure script.
302 - Instance allocator support. Add and import instance accept a
303 ``--iallocator`` parameter, and call that instance allocator to decide
304 which node to use for the instance. The iallocator document describes
305 what's expected from an allocator script.
306 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
307 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
308 node is lost there is still enough memory to fail over the instances
310 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
311 ``gnt-cluster verify``, to check for site-specific compliance. All the
312 hooks will run, and their output, if any, will be displayed. Any
313 failing hook will make the verification return an error value.
314 - ``gnt-cluster verify`` now checks that its peers are reachable on the
315 primary and secondary interfaces
316 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
317 that is still declared as part of the cluster and has failed.
318 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
319 specifying output fields, that just adds the chosen fields to the
321 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
322 export from the filesystem.
323 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
324 have been added. Using them you can enable/disable acpi and pae
325 support, and specify a path for a cd image to be exported to the
326 instance. These parameters as the name suggest only work on HVM
328 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
329 PAE support will be set to the previously hardcoded values, but the
330 (previously hardcoded) path to the CDROM ISO image will be unset and
331 if required, needs to be set manually with ``gnt-instance modify``
333 - The address to which an instance's VNC console is bound is now
334 selectable per-instance, rather than being cluster wide. Of course
335 this only applies to instances controlled via VNC, so currently just
336 applies to HVM clusters.
342 - more tweaks to the disk activation code (especially helpful for DRBD)
343 - change the default ``gnt-instance list`` output format, now there is
344 one combined status field (see the manpage for the exact values this
346 - some more fixes for the mac export to hooks change
347 - make Ganeti not break with DRBD 8.2.x (which changed the version
348 format in ``/proc/drbd``) (issue 24)
349 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
350 template, allowing migration from DRBD0.7+MD to DRBD8
356 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
358 - add command aliases infrastructure and a few aliases
359 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
360 man pages and the ``--help`` option of ``gnt-node
361 list``/``gnt-instance list``
362 - fix ``gnt-backup list`` with down nodes (issue 21)
363 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
364 - fix the dist archive and add a check for including svn/git files in
366 - some developer-related changes: improve the burnin and the QA suite,
367 add an upload script for testing during development
373 - experimental HVM support, read the install document, section
374 "Initializing the cluster"
375 - allow for the PVM hypervisor per-instance kernel and initrd paths
376 - add a new command ``gnt-cluster verify-disks`` which uses a new
377 algorithm to improve the reconnection of the DRBD pairs if the device
378 on the secondary node has gone away
379 - make logical volume code auto-activate LVs at disk activation time
380 - slightly improve the speed of activating disks
381 - allow specification of the MAC address at instance creation time, and
382 changing it later via ``gnt-instance modify``
383 - fix handling of external commands that generate lots of output on
385 - update documentation with regard to minimum version of DRBD8 supported
391 - Log the ``xm create`` output to the node daemon log on failure (to
392 help diagnosing the error)
393 - In debug mode, log all external commands output if failed to the logs
394 - Change parsing of lvm commands to ignore stderr
400 - Another round of updates to the DRBD 8 code to deal with more failures
401 in the replace secondary node operation
402 - Some more logging of failures in disk operations (lvm, drbd)
403 - A few documentation updates
410 - Change configuration file format from Python's Pickle to JSON.
411 Upgrading is possible using the cfgupgrade utility.
412 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
413 faster replace disks and is more stable (DRBD 8 has many improvements
414 compared to DRBD 0.7)
415 - Added command line tags support (see man pages for ``gnt-instance``,
416 ``gnt-node``, ``gnt-cluster``)
417 - Added instance rename support
418 - Added multi-instance startup/shutdown
419 - Added cluster rename support
420 - Added ``gnt-node evacuate`` to simplify some node operations
421 - Added instance reboot operation that can speedup reboot as compared to
423 - Soften the requirement that hostnames are in FQDN format
424 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
426 - Removed dependency on debian's patched fping that uses the
427 non-standard ``-S`` option
428 - Now the OS definitions are searched for in multiple, configurable
429 paths (easier for distros to package)
430 - Some changes to the hooks infrastructure (especially the new
431 post-configuration update hook)
432 - Other small bugfixes
