Version 2.0.4 |
4 |
------------- |
5 |
|
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 |
11 |
scripts |
12 |
- Fixed the example startup script provided |
13 |
- Fixed insserv dependencies in the example startup script (patch from |
14 |
Debian) |
15 |
- Fixed handling of drained nodes in the iallocator framework |
16 |
- Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug |
17 |
#528618) |
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 |
21 |
shutdown |
22 |
- Fixed error reporting from LUs, previously all errors were converted |
23 |
into execution errors |
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 |
35 |
/etc/hosts |
36 |
- Added more node information to RAPI responses |
37 |
- Added a ``gnt-job watch`` command that allows following the ouput of a |
38 |
job |
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 |
42 |
automatically |
43 |
- Converted instance reinstall to multi-instance model |
44 |
|
45 |
|
46 |
Version 2.0.3 |
47 |
------------- |
48 |
|
49 |
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
50 |
to allow using the pre-2.0.2 behaviour in activation, if any existing |
51 |
instances have mismatched disk sizes in the configuration |
52 |
- Added ``gnt-cluster repair-disk-sizes`` command to check and update |
53 |
any configuration mismatches for disk sizes |
54 |
- Added ``gnt-master cluste-failover --no-voting`` to allow master |
55 |
failover to work on two-node clusters |
56 |
- Fixed the ``--net`` option of ``gnt-backup import``, which was |
57 |
unusable |
58 |
- Fixed detection of OS script errors in ``gnt-backup export`` |
59 |
- Fixed exit code of ``gnt-backup export`` |
60 |
|
61 |
|
62 |
Version 2.0.2 |
63 |
------------- |
64 |
|
65 |
- Added experimental support for stripped logical volumes; this should |
66 |
enhance performance but comes with a higher complexity in the block |
67 |
device handling; stripping is only enabled when passing |
68 |
``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
69 |
affected even in the non-stripped mode |
70 |
- Improved resiliency against transient failures at the end of DRBD |
71 |
resyncs, and in general of DRBD resync checks |
72 |
- Fixed a couple of issues with exports and snapshot errors |
73 |
- Fixed a couple of issues in instance listing |
74 |
- Added display of the disk size in ``gnt-instance info`` |
75 |
- Fixed checking for valid OSes in instance creation |
76 |
- Fixed handling of the "vcpus" parameter in instance listing and in |
77 |
general of invalid parameters |
78 |
- Fixed http server library, and thus RAPI, to handle invalid |
79 |
username/password combinations correctly; this means that now they |
80 |
report unauthorized for queries too, not only for modifications, |
81 |
allowing earlier detect of configuration problems |
82 |
- Added a new "role" node list field, equivalent to the master/master |
83 |
candidate/drained/offline flags combinations |
84 |
- Fixed cluster modify and changes of candidate pool size |
85 |
- Fixed cluster verify error messages for wrong files on regular nodes |
86 |
- Fixed a couple of issues with node demotion from master candidate role |
87 |
- Fixed node readd issues |
88 |
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
89 |
- Added a new ``--no-voting`` option for masterfailover to fix failover |
90 |
on two-nodes clusters when the former master node is unreachable |
91 |
- Added instance reinstall over RAPI |
92 |
|
93 |
|
94 |
Version 2.0.1 |
95 |
------------- |
96 |
|
97 |
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
98 |
allow re-adding the start in single-user option (regression from 1.2) |
99 |
- the watcher writes the instance status to a file, to allow monitoring |
100 |
to report the instance status (from the master) based on cached |
101 |
results of the watcher's queries; while this can get stale if the |
102 |
watcher is being locked due to other work on the cluster, this is |
103 |
still an improvement |
104 |
- the watcher now also restarts the node daemon and the rapi daemon if |
105 |
they died |
106 |
- fixed the watcher to handle full and drained queue cases |
107 |
- hooks export more instance data in the environment, which helps if |
108 |
hook scripts need to take action based on the instance's properties |
109 |
(no longer need to query back into ganeti) |
110 |
- instance failovers when the instance is stopped do not check for free |
111 |
RAM, so that failing over a stopped instance is possible in low memory |
112 |
situations |
113 |
- rapi uses queries for tags instead of jobs (for less job traffic), and |
114 |
for cluster tags it won't talk to masterd at all but read them from |
115 |
ssconf |
116 |
- a couple of error handling fixes in RAPI |
117 |
- drbd handling: improved the error handling of inconsistent disks after |
118 |
resync to reduce the frequency of "there are some degraded disks for |
119 |
this instance" messages |
120 |
- fixed a bug in live migration when DRBD doesn't want to reconnect (the |
121 |
error handling path called a wrong function name) |
122 |
|
123 |
|
124 |
Version 2.0.0 final |
125 |
------------------- |
126 |
|
127 |
- no changes from rc5 |
128 |
|
129 |
|
130 |
Version 2.0 release candidate 5 |
131 |
------------------------------- |
132 |
|
133 |
- fix a couple of bugs (validation, argument checks) |
134 |
- fix ``gnt-cluster getmaster`` on non-master nodes (regression) |
135 |
- some small improvements to RAPI and IAllocator |
136 |
- make watcher automatically start the master daemon if down |
137 |
|
138 |
|
139 |
Version 2.0 release candidate 4 |
140 |
------------------------------- |
141 |
|
142 |
- change the OS list to not require locks; this helps with big clusters |
143 |
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the |
144 |
volume group is broken |
145 |
- ``gnt-instance info``, without any arguments, doesn't run for all |
146 |
instances anymore; either pass ``--all`` or pass the desired |
147 |
instances; this helps against mistakes on big clusters where listing |
148 |
the information for all instances takes a long time |
149 |
- miscellaneous doc and man pages fixes |
150 |
|
151 |
|
152 |
Version 2.0 release candidate 3 |
153 |
------------------------------- |
154 |
|
155 |
- Change the internal locking model of some ``gnt-node`` commands, in |
156 |
order to reduce contention (and blocking of master daemon) when |
157 |
batching many creation/reinstall jobs |
158 |
- Fixes to Xen soft reboot |
159 |
- No longer build documentation at build time, instead distribute it in |
160 |
the archive, in order to reduce the need for the whole docbook/rst |
161 |
toolchains |
162 |
|
163 |
|
164 |
Version 2.0 release candidate 2 |
165 |
------------------------------- |
166 |
|
167 |
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0 |
168 |
- Fix watcher startup sequence, improves the behaviour of busy clusters |
169 |
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance |
170 |
replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC |
171 |
bind address and other places |
172 |
- Some documentation fixes and updates |
173 |
|
174 |
|
175 |
Version 2.0 release candidate 1 |
176 |
------------------------------- |
177 |
|
178 |
- More documentation updates, now all docs should be more-or-less |
179 |
up-to-date |
180 |
- A couple of small fixes (mixed hypervisor clusters, offline nodes, |
181 |
etc.) |
182 |
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM |
183 |
and KVM) |
184 |
- Fix an issue related to $libdir/run/ganeti and cluster creation |
185 |
|
186 |
|
187 |
Version 2.0 beta 2 |
188 |
------------------ |
189 |
|
190 |
- Xen PVM and KVM have switched the default value for the instance root |
191 |
disk to the first partition on the first drive, instead of the whole |
192 |
drive; this means that the OS installation scripts must be changed |
193 |
accordingly |
194 |
- Man pages have been updated |
195 |
- RAPI has been switched by default to HTTPS, and the exported functions |
196 |
should all work correctly |
197 |
- RAPI v1 has been removed |
198 |
- Many improvements to the KVM hypervisor |
199 |
- Block device errors are now better reported |
200 |
- Many other bugfixes and small improvements |
201 |
|
202 |
|
203 |
Version 2.0 beta 1 |
204 |
------------------ |
205 |
|
206 |
- Version 2 is a general rewrite of the code and therefore the |
207 |
differences are too many to list, see the design document for 2.0 in |
208 |
the ``doc/`` subdirectory for more details |
209 |
- In this beta version there is not yet a migration path from 1.2 (there |
210 |
will be one in the final 2.0 release) |
211 |
- A few significant changes are: |
212 |
|
213 |
- all commands are executed by a daemon (``ganeti-masterd``) and the |
214 |
various ``gnt-*`` commands are just front-ends to it |
215 |
- all the commands are entered into, and executed from a job queue, |
216 |
see the ``gnt-job(8)`` manpage |
217 |
- the RAPI daemon supports read-write operations, secured by basic |
218 |
HTTP authentication on top of HTTPS |
219 |
- DRBD version 0.7 support has been removed, DRBD 8 is the only |
220 |
supported version (when migrating from Ganeti 1.2 to 2.0, you need |
221 |
to migrate to DRBD 8 first while still running Ganeti 1.2) |
222 |
- DRBD devices are using statically allocated minor numbers, which |
223 |
will be assigned to existing instances during the migration process |
224 |
- there is support for both Xen PVM and Xen HVM instances running on |
225 |
the same cluster |
226 |
- KVM virtualization is supported too |
227 |
- file-based storage has been implemented, which means that it is |
228 |
possible to run the cluster without LVM and DRBD storage, for |
229 |
example using a shared filesystem exported from shared storage (and |
230 |
still have live migration) |
231 |
|
232 |
|
233 |
Version 1.2.7 |
234 |
------------- |
235 |
|
236 |
- Change the default reboot type in ``gnt-instance reboot`` to "hard" |
237 |
- Reuse the old instance mac address by default on instance import, if |
238 |
the instance name is the same. |
239 |
- Handle situations in which the node info rpc returns incomplete |
240 |
results (issue 46) |
241 |
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify`` |
242 |
- Improved version of batcher: |
243 |
|
244 |
- state file support |
245 |
- instance mac address support |
246 |
- support for HVM clusters/instances |
247 |
|
248 |
- Add an option to show the number of cpu sockets and nodes in |
249 |
``gnt-node list`` |
250 |
- Support OSes that handle more than one version of the OS api (but do |
251 |
not change the current API in any other way) |
252 |
- Fix ``gnt-node migrate`` |
253 |
- ``gnt-debug`` man page |
254 |
- Fixes various more typos and small issues |
255 |
- Increase disk resync maximum speed to 60MB/s (from 30MB/s) |
256 |
|
257 |
|
258 |
Version 1.2.6 |
259 |
------------- |
260 |
|
261 |
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
262 |
type of disk exported to fully virtualized instances. |
263 |
- provide access to the serial console of HVM instances |
264 |
- instance auto_balance flag, set by default. If turned off it will |
265 |
avoid warnings on cluster verify if there is not enough memory to fail |
266 |
over an instance. in the future it will prevent automatically failing |
267 |
it over when we will support that. |
268 |
- batcher tool for instance creation, see ``tools/README.batcher`` |
269 |
- ``gnt-instance reinstall --select-os`` to interactively select a new |
270 |
operating system when reinstalling an instance. |
271 |
- when changing the memory amount on instance modify a check has been |
272 |
added that the instance will be able to start. also warnings are |
273 |
emitted if the instance will not be able to fail over, if auto_balance |
274 |
is true. |
275 |
- documentation fixes |
276 |
- sync fields between ``gnt-instance list/modify/add/import`` |
277 |
- fix a race condition in drbd when the sync speed was set after giving |
278 |
the device a remote peer. |
279 |
|
280 |
|
281 |
Version 1.2.5 |
282 |
------------- |
283 |
|
284 |
- note: the allowed size and number of tags per object were reduced |
285 |
- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups |
286 |
- fixed twisted 8.x compatibility |
287 |
- fixed ``gnt-instance replace-disks`` with iallocator |
288 |
- add TCP keepalives on twisted connections to detect restarted nodes |
289 |
- disk increase support, see ``gnt-instance grow-disk`` |
290 |
- implement bulk node/instance query for RAPI |
291 |
- add tags in node/instance listing (optional) |
292 |
- experimental migration (and live migration) support, read the man page |
293 |
for ``gnt-instance migrate`` |
294 |
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
295 |
has some small improvements in handling its state file |
296 |
|
297 |
|
298 |
Version 1.2.4 |
299 |
------------- |
300 |
|
301 |
- Experimental readonly, REST-based remote API implementation; |
302 |
automatically started on master node, TCP port 5080, if enabled by |
303 |
``--enable-rapi`` parameter to configure script. |
304 |
- Instance allocator support. Add and import instance accept a |
305 |
``--iallocator`` parameter, and call that instance allocator to decide |
306 |
which node to use for the instance. The iallocator document describes |
307 |
what's expected from an allocator script. |
308 |
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
309 |
``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
310 |
node is lost there is still enough memory to fail over the instances |
311 |
that reside on it. |
312 |
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
313 |
``gnt-cluster verify``, to check for site-specific compliance. All the |
314 |
hooks will run, and their output, if any, will be displayed. Any |
315 |
failing hook will make the verification return an error value. |
316 |
- ``gnt-cluster verify`` now checks that its peers are reachable on the |
317 |
primary and secondary interfaces |
318 |
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
319 |
that is still declared as part of the cluster and has failed. |
320 |
- ``gnt-* list`` commands now accept a new ``-o +field`` way of |
321 |
specifying output fields, that just adds the chosen fields to the |
322 |
default ones. |
323 |
- ``gnt-backup`` now has a new ``remove`` command to delete an existing |
324 |
export from the filesystem. |
325 |
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
326 |
have been added. Using them you can enable/disable acpi and pae |
327 |
support, and specify a path for a cd image to be exported to the |
328 |
instance. These parameters as the name suggest only work on HVM |
329 |
clusters. |
330 |
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
331 |
PAE support will be set to the previously hardcoded values, but the |
332 |
(previously hardcoded) path to the CDROM ISO image will be unset and |
333 |
if required, needs to be set manually with ``gnt-instance modify`` |
334 |
after the upgrade. |
335 |
- The address to which an instance's VNC console is bound is now |
336 |
selectable per-instance, rather than being cluster wide. Of course |
337 |
this only applies to instances controlled via VNC, so currently just |
338 |
applies to HVM clusters. |
339 |
|
340 |
|
341 |
Version 1.2.3 |
342 |
------------- |
343 |
|
344 |
- more tweaks to the disk activation code (especially helpful for DRBD) |
345 |
- change the default ``gnt-instance list`` output format, now there is |
346 |
one combined status field (see the manpage for the exact values this |
347 |
field will have) |
348 |
- some more fixes for the mac export to hooks change |
349 |
- make Ganeti not break with DRBD 8.2.x (which changed the version |
350 |
format in ``/proc/drbd``) (issue 24) |
351 |
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk |
352 |
template, allowing migration from DRBD0.7+MD to DRBD8 |
353 |
|
354 |
|
355 |
Version 1.2.2 |
356 |
------------- |
357 |
|
358 |
- fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM |
359 |
support (issue 23) |
360 |
- add command aliases infrastructure and a few aliases |
361 |
- allow listing of VCPUs in the ``gnt-instance list`` and improve the |
362 |
man pages and the ``--help`` option of ``gnt-node |
363 |
list``/``gnt-instance list`` |
364 |
- fix ``gnt-backup list`` with down nodes (issue 21) |
365 |
- change the tools location (move from $pkgdatadir to $pkglibdir/tools) |
366 |
- fix the dist archive and add a check for including svn/git files in |
367 |
the future |
368 |
- some developer-related changes: improve the burnin and the QA suite, |
369 |
add an upload script for testing during development |
370 |
|
371 |
|
372 |
Version 1.2.1 |
373 |
------------- |
374 |
|
375 |
- experimental HVM support, read the install document, section |
376 |
"Initializing the cluster" |
377 |
- allow for the PVM hypervisor per-instance kernel and initrd paths |
378 |
- add a new command ``gnt-cluster verify-disks`` which uses a new |
379 |
algorithm to improve the reconnection of the DRBD pairs if the device |
380 |
on the secondary node has gone away |
381 |
- make logical volume code auto-activate LVs at disk activation time |
382 |
- slightly improve the speed of activating disks |
383 |
- allow specification of the MAC address at instance creation time, and |
384 |
changing it later via ``gnt-instance modify`` |
385 |
- fix handling of external commands that generate lots of output on |
386 |
stderr |
387 |
- update documentation with regard to minimum version of DRBD8 supported |
388 |
|
389 |
|
390 |
Version 1.2.0 |
391 |
------------- |
392 |
|
393 |
- Log the ``xm create`` output to the node daemon log on failure (to |
394 |
help diagnosing the error) |
395 |
- In debug mode, log all external commands output if failed to the logs |
396 |
- Change parsing of lvm commands to ignore stderr |
397 |
|
398 |
|
399 |
Version 1.2b3 |
400 |
------------- |
401 |
|
402 |
- Another round of updates to the DRBD 8 code to deal with more failures |
403 |
in the replace secondary node operation |
404 |
- Some more logging of failures in disk operations (lvm, drbd) |
405 |
- A few documentation updates |
406 |
- QA updates |
407 |
|
408 |
|
409 |
Version 1.2b2 |
410 |
------------- |
411 |
|
412 |
- Change configuration file format from Python's Pickle to JSON. |
413 |
Upgrading is possible using the cfgupgrade utility. |
414 |
- Add support for DRBD 8.0 (new disk template ``drbd``) which allows for |
415 |
faster replace disks and is more stable (DRBD 8 has many improvements |
416 |
compared to DRBD 0.7) |
417 |
- Added command line tags support (see man pages for ``gnt-instance``, |
418 |
``gnt-node``, ``gnt-cluster``) |
419 |
- Added instance rename support |
420 |
- Added multi-instance startup/shutdown |
421 |
- Added cluster rename support |
422 |
- Added ``gnt-node evacuate`` to simplify some node operations |
423 |
- Added instance reboot operation that can speedup reboot as compared to |
424 |
stop and start |
425 |
- Soften the requirement that hostnames are in FQDN format |
426 |
- The ``ganeti-watcher`` now activates drbd pairs after secondary node |
427 |
reboots |
428 |
- Removed dependency on debian's patched fping that uses the |
429 |
non-standard ``-S`` option |
430 |
