2 - Added experimental support for stripped logical volumes; this should
3 enhance performance but comes with a higher complexity in the block
4 device handling; stripping is only enabled when passing
5 --with-lvm-stripecount=N to configure, but codepaths are affected
6 even in the non-stripped mode
7 - Improved resiliency against transient failures at the end of DRBD
8 resyncs, and in general of DRBD resync checks
9 - Fixed a couple of issues with exports and snapshot errors
10 - Fixed a couple of issues in instance listing
11 - Added display of the disk size in “gnt-instance info”
12 - Fixed checking for valid OSes in instance creation
13 - Fixed handling of the ‘vcpus’ parameter in instance listing and in
14 general of invalid parameters
15 - Fixed http server library, and thus RAPI, to handle invalid
16 username/password combinations correctly; this means that now they
17 report unauthorized for queries too, not only for modifications,
18 allowing earlier detect of configuration problems
19 - Added a new ‘role’ node list field, equivalent to the master/master
20 candidate/drained/offline flags combinations
21 - Fixed cluster modify and changes of candidate pool size
22 - Fixed cluster verify error messages for wrong files on regular nodes
23 - Fixed a couple of issues with node demotion from master candidate
25 - Fixed node readd issues
26 - Added non-interactive mode for “ganeti-masterd --no-voting” startup
27 - Added a new ‘--no-voting’ option for masterfailover to fix failover
28 on two-nodes clusters when the former master node is unreachable
29 - Added instance reinstall over RAPI
32 - added -H/-B startup parameters to gnt-instance, which will allow
33 re-adding the start in single-user option (regression from 1.2)
34 - the watcher writes the instance status to a file, to allow
35 monitoring to report the instance status (from the master) based on
36 cached results of the watcher's queries; while this can get stale if
37 the watcher is being locked due to other work on the cluster, this
38 is still an improvement
39 - the watcher now also restarts the node daemon and the rapi daemon if
41 - fixed the watcher to handle full and drained queue cases
42 - hooks export more instance data in the environment, which helps if
43 hook scripts need to take action based on the instance's properties
44 (no longer need to query back into ganeti)
45 - instance failovers when the instance is stopped do not check for
46 free RAM, so that failing over a stopped instance is possible in low
48 - rapi uses queries for tags instead of jobs (for less job traffic),
49 and for cluster tags it won't talk to masterd at all but read them
51 - a couple of error handling fixes in RAPI
52 - drbd handling: improved the error handling of inconsistent disks
53 after resync to reduce the frequency of "there are some degraded
54 disks for this instance" message
55 - fixed a bug in live migration when DRBD doesn't want to reconnect
56 (the error handling path called a wrong function name)
61 Version 2.0 release candidate 5
62 - fix a couple of bugs (validation, argument checks)
63 - fix gnt-cluster getmaster on non-master nodes (regression)
64 - some small improvements to RAPI and IAllocator
65 - make watcher automatically start the master daemon if down
67 Version 2.0 release candidate 4
68 - change the OS list to not require locks; this helps with big
70 - fix gnt-cluster verify and gnt-cluster verify-disks when the volume
72 - “gnt-instance info”, without any arguments, doesn't run for all
73 instances anymore; either pass ‘--all’ or pass the desired
74 instances; this helps against mistakes on big clusters where listing
75 the information for all instances takes a long time
76 - miscellaneous doc and man pages fixes
78 Version 2.0 release candidate 3
79 - Change the internal locking model of some gnt-node commands, in
80 order to reduce contention (and blocking of master daemon) when
81 batching many creation/reinstall jobs
82 - Fixes to Xen soft reboot
83 - No longer build documentation at 'make' time, instead distribute it
84 in the archive, in order to reduce the need for the whole
85 docbook/rst toolchains
87 Version 2.0 release candidate 2
88 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to
90 - Fix watcher startup sequence, improves the behaviour of busy
92 - Some other fixes in cluster verify, replace-disks, gnt-instance add,
93 gnt-cluster queue, KVM VNC bind address and other places
94 - Some documentation fixes and updates
96 Version 2.0 release candidate 1
97 - More documentation updates, now all docs should be more-or-less
99 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
101 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen
103 - Fix an issue related to $libdir/run/ganeti and cluster creation
106 - Xen PVM and KVM have switched the default value for the instance
107 root disk to the first partition on the first drive, instead of the
108 whole drive; this means that the OS installation scripts must be
110 - Man pages have been updated
111 - RAPI has been switched by default to HTTPS, and the exported
112 functions should all work correctly
113 - RAPI v1 has been removed
114 - Many improvements to the KVM hypervisor
115 - Block device errors are now better reported
116 - Many other bugfixes and small improvements
119 - Version 2 is a general rewrite of the code and therefore the
120 differences are too many to list, see the design document for 2.0 in
121 the doc/ subdirectory for more details
122 - In this beta version there is not yet a migration path from 1.2
123 (there will be one in the final 2.0 release)
124 - A few significant changes are:
125 - all commands are executed by a daemon (ganeti-masterd) and the
126 various gnt-* commands are just front-ends to it
127 - all the commands are entered into, and executed from a job queue,
129 - the RAPI daemon supports read-write operations, secured by basic
130 HTTP authentication on top of HTTPS
131 - DRBD version 0.7 support has been removed, DRBD 8 is the only
132 supported version (when migrating from Ganeti 1.2 to 2.0, you need
133 to migrate to DRBD 8 first while still running Ganeti 1.2)
134 - DRBD devices are using statically allocated minor numbers, which
135 will be assigned to existing instances during the migration
137 - there is support for both Xen PVM and Xen HVM instances running on
139 - KVM virtualization is supported too
140 - file-based storage has been implemented, which means that it is
141 possible to run the cluster without LVM and DRBD storage, for
142 example using a shared filesystem exported from shared storage
143 (and still have live migration)
146 - Change the default reboot type in gnt-instance reboot to "hard"
147 - Reuse the old instance mac address by default on instance import,
148 if the instance name is the same.
149 - Handle situations in which the node info rpc returns incomplete results
151 - Add checks for tcp/udp ports collisions in gnt-cluster verify
152 - Improved version of batcher:
154 - instance mac address support
155 - support for HVM clusters/instances
156 - Add an option to show the number of cpu sockets and nodes in gnt-node list
157 - Support OSes that handle more than one version of the OS api
158 (but do not change the current API in any other way)
159 - Fix gnt-node migrate
161 - Fixes various more typos&small issues
162 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
165 - new --hvm-nic-type and --hvm-disk-type flags to control the type of disk
166 exported to fully virtualized instances.
167 - provide access to the serial console of HVM instances
168 - instance auto_balance flag, set by default. If turned off it will avoid
169 warnings on cluster verify if there is not enough memory to fail over an
170 instance. in the future it will prevent automatically failing it over when
171 we will support that.
172 - batcher tool for instance creation, see /tools/README.batcher
173 - gnt-instance reinstall --select-os to interactively select a new operating
174 system when reinstalling an instance.
175 - when changing the memory amount on instance modify a check has been added
176 that the instance will be able to start. also warnings are emitted if the
177 instance will not be able to fail over, if auto_balance is true.
178 - documentation fixes
179 - sync fields between instance list/modify/add/import
180 - fix a race condition in drbd when the sync speed was set after giving the
181 device a remote peer.
184 - note: the allowed size and number of tags per object were reduced
185 - fix a bug in “gnt-cluster verify” with inconsistent volume groups
186 - fixed twisted 8.x compatibility
187 - fixed gnt-instance replace-disks with iallocator
188 - add TCP keepalives on twisted connections to detect restarted nodes
189 - disk increase support, see “gnt-instance grow-disk”
190 - implement bulk node/instance query for RAPI
191 - add tags in node/instance listing (optional)
192 - experimental migration (and live migration) support, read the man
193 page for “gnt-instance migrate”
194 - the ganeti-watcher logs are now timestamped, and the watcher also
195 has some small improvements in handling its state file
198 - Experimental readonly, REST-based remote API implementation; automatically
199 started on master node, TCP port 5080, if enabled by --enable-rapi
200 parameter to configure script.
201 - Instance allocator support. Add and import instance accept a --iallocator
202 parameter, and call that instance allocator to decide which node to use for
203 the instance. The iallocator document describes what's expected from an
205 - gnt-cluster verify N+1 memory redundancy checks: Unless passed the
206 --no-nplus1-mem option gnt-cluster verify now checks that if a node is lost
207 there is still enough memory to fail over the instances that reside on it.
208 - gnt-cluster verify hooks: it is now possible to add post-hooks to
209 gnt-cluster verify, to check for site-specific compliance. All the hooks
210 will run, and their output, if any, will be displayed. Any failing hook
211 will make the verification return an error value.
212 - gnt-cluster verify now checks that its peers are reachable on the primary
213 and secondary interfaces
214 - gnt-node add now supports the --readd option, to readd a node that is still
215 declared as part of the cluster and has failed.
216 - gnt-* list commands now accept a new -o +field way of specifying output
217 fields, that just adds the chosen fields to the default ones.
218 - gnt-backup now has a new "remove" command to delete an existing export from
220 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path have
221 been added. Using them you can enable/disable acpi and pae support, and
222 specify a path for a cd image to be exported to the instance. These
223 parameters as the name suggest only work on HVM clusters.
224 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and PAE
225 support will be set to the previously hardcoded values, but the (previously
226 hardcoded) path to the CDROM ISO image will be unset and if required, needs
227 to be set manually with gnt-instance modify after the upgrade..
228 - The address to which an instance's VNC console is bound is now selectable
229 per-instance, rather than being cluster wide. Of course this only applies
230 to instances controlled via VNC, so currently just applies to HVM clusters.
233 - more tweaks to the disk activation code (especially helpful for DRBD)
234 - change the default ‘gnt-instance list’ output format, now there is
235 one combined status field (see the manpage for the exact values this
237 - some more fixes for the mac export to hooks change
238 - make Ganeti not break with DRBD 8.2.x (which changed the version
239 format in /proc/drbd) (issue 24)
240 - add an upgrade tool from ‘remote_raid1’ disk template to ‘drbd’ disk
241 template, allowing migration from DRBD0.7+MD to DRBD8
244 - fix ‘gnt-instance modify’ breakage introduced in 1.2.1 with the HVM
246 - add command aliases infrastructure and a few aliases
247 - allow listing of VCPUs in the gnt-instance list and improve the man
248 pages and the --help option of gnt-node/gnt-instance list
249 - fix gnt-backup list with down nodes (issue 21)
250 - change the tools location (move from $pkgdatadir to
252 - fix the dist archive and add a check for including svn/git files in
254 - some developer-related changes: improve the burnin and the QA
255 suite, add an upload script for testing during development
258 - experimental HVM support, read the install document, section
259 "Initializing the cluster"
260 - allow for the PVM hypervisor per-instance kernel and initrd paths
261 - add a new command ‘gnt-cluster verify-disks’ which uses a new
262 algorithm to improve the reconnection of the DRBD pairs if the
263 device on the secondary node has gone away
264 - make logical volume code auto-activate LVs at disk activation time
265 - slightly improve the speed of activating disks
266 - allow specification of the MAC address at instance creation time,
267 and changing it later via ‘gnt-instance modify’
268 - fix handling of external commands that generate lots of output on
270 - update documentation with regard to minimum version of DRBD8
274 - Log the ‘xm create’ output to the node daemon log on failure (to
275 help diagnosing the error)
276 - In debug mode, log all external commands output if failed to the
278 - Change parsing of lvm commands to ignore stderr
281 - Another round of updates to the DRBD 8 code to deal with more
282 failures in the replace secondary node operation
283 - Some more logging of failures in disk operations (lvm, drbd)
284 - A few documentation updates
288 - Change configuration file format from Python's Pickle to JSON.
289 Upgrading is possible using the cfgupgrade utility.
290 - Add support for DRBD 8.0 (new disk template `drbd`) which allows for
291 faster replace disks and is more stable (DRBD 8 has many
292 improvements compared to DRBD 0.7)
293 - Added command line tags support (see man pages for gnt-instance,
294 gnt-node, gnt-cluster)
295 - Added instance rename support
296 - Added multi-instance startup/shutdown
297 - Added cluster rename support
298 - Added `gnt-node evacuate` to simplify some node operations
299 - Added instance reboot operation that can speedup reboot as compared
301 - Soften the requirement that hostnames are in FQDN format
302 - The ganeti-watcher now activates drbd pairs after secondary node
304 - Removed dependency on debian's patched fping that uses the
305 non-standard -S option
306 - Now the OS definitions are searched for in multiple, configurable
307 paths (easier for distros to package)
308 - Some changes to the hooks infrastructure (especially the new
309 post-configuration update hook)
310 - Other small bugfixes
