134 | 61b5e342 | Michael Hanselmann | |
135 | aa287e8c | Michael Hanselmann | |
136 | 9d725d41 | Iustin Pop | Version 2.0.3 |
137 | 61b5e342 | Michael Hanselmann | ------------- |
138 | 61b5e342 | Michael Hanselmann | |
139 | 61b5e342 | Michael Hanselmann | - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
140 | 61b5e342 | Michael Hanselmann | to allow using the pre-2.0.2 behaviour in activation, if any existing |
141 | 61b5e342 | Michael Hanselmann | instances have mismatched disk sizes in the configuration |
142 | 7faf5110 | Michael Hanselmann | - Added ``gnt-cluster repair-disk-sizes`` command to check and update |
143 | 7faf5110 | Michael Hanselmann | any configuration mismatches for disk sizes |
144 | 61b5e342 | Michael Hanselmann | - Added ``gnt-master cluste-failover --no-voting`` to allow master |
145 | 61b5e342 | Michael Hanselmann | failover to work on two-node clusters |
146 | aa287e8c | Michael Hanselmann | - Fixed the ``--net`` option of ``gnt-backup import``, which was |
147 | aa287e8c | Michael Hanselmann | unusable |

149 | 61b5e342 | Michael Hanselmann | - Fixed exit code of ``gnt-backup export`` |
150 | 61b5e342 | Michael Hanselmann | |
151 | 9d725d41 | Iustin Pop | |
152 | 550a995a | Iustin Pop | Version 2.0.2 |
153 | 61b5e342 | Michael Hanselmann | ------------- |
154 | 61b5e342 | Michael Hanselmann | |
155 | 61b5e342 | Michael Hanselmann | - Added experimental support for stripped logical volumes; this should |
156 | 61b5e342 | Michael Hanselmann | enhance performance but comes with a higher complexity in the block |
157 | 61b5e342 | Michael Hanselmann | device handling; stripping is only enabled when passing |
158 | 61b5e342 | Michael Hanselmann | ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
159 | 61b5e342 | Michael Hanselmann | affected even in the non-stripped mode |
160 | 61b5e342 | Michael Hanselmann | - Improved resiliency against transient failures at the end of DRBD |
161 | 61b5e342 | Michael Hanselmann | resyncs, and in general of DRBD resync checks |
162 | 61b5e342 | Michael Hanselmann | - Fixed a couple of issues with exports and snapshot errors |
163 | 61b5e342 | Michael Hanselmann | - Fixed a couple of issues in instance listing |
164 | 61b5e342 | Michael Hanselmann | - Added display of the disk size in ``gnt-instance info`` |
165 | 61b5e342 | Michael Hanselmann | - Fixed checking for valid OSes in instance creation |
166 | aa287e8c | Michael Hanselmann | - Fixed handling of the "vcpus" parameter in instance listing and in |
167 | 61b5e342 | Michael Hanselmann | general of invalid parameters |
168 | 61b5e342 | Michael Hanselmann | - Fixed http server library, and thus RAPI, to handle invalid |
169 | 61b5e342 | Michael Hanselmann | username/password combinations correctly; this means that now they |
170 | 61b5e342 | Michael Hanselmann | report unauthorized for queries too, not only for modifications, |
171 | 61b5e342 | Michael Hanselmann | allowing earlier detect of configuration problems |
172 | aa287e8c | Michael Hanselmann | - Added a new "role" node list field, equivalent to the master/master |
173 | 61b5e342 | Michael Hanselmann | candidate/drained/offline flags combinations |
174 | 61b5e342 | Michael Hanselmann | - Fixed cluster modify and changes of candidate pool size |
175 | 61b5e342 | Michael Hanselmann | - Fixed cluster verify error messages for wrong files on regular nodes |
176 | 61b5e342 | Michael Hanselmann | - Fixed a couple of issues with node demotion from master candidate role |
177 | 61b5e342 | Michael Hanselmann | - Fixed node readd issues |
178 | 61b5e342 | Michael Hanselmann | - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
179 | aa287e8c | Michael Hanselmann | - Added a new ``--no-voting`` option for masterfailover to fix failover |
180 | aa287e8c | Michael Hanselmann | on two-nodes clusters when the former master node is unreachable |
181 | 61b5e342 | Michael Hanselmann | - Added instance reinstall over RAPI |
182 | 61b5e342 | Michael Hanselmann | |
183 | 550a995a | Iustin Pop | |
184 | 0dea942c | Iustin Pop | Version 2.0.1 |
185 | 61b5e342 | Michael Hanselmann | ------------- |
186 | 61b5e342 | Michael Hanselmann | |
187 | 61b5e342 | Michael Hanselmann | - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
188 | 61b5e342 | Michael Hanselmann | allow re-adding the start in single-user option (regression from 1.2) |
189 | 61b5e342 | Michael Hanselmann | - the watcher writes the instance status to a file, to allow monitoring |
190 | 61b5e342 | Michael Hanselmann | to report the instance status (from the master) based on cached |
191 | 61b5e342 | Michael Hanselmann | results of the watcher's queries; while this can get stale if the |
192 | 61b5e342 | Michael Hanselmann | watcher is being locked due to other work on the cluster, this is |
193 | 61b5e342 | Michael Hanselmann | still an improvement |
194 | 61b5e342 | Michael Hanselmann | - the watcher now also restarts the node daemon and the rapi daemon if |
195 | 61b5e342 | Michael Hanselmann | they died |
196 | 61b5e342 | Michael Hanselmann | - fixed the watcher to handle full and drained queue cases |
197 | 7faf5110 | Michael Hanselmann | - hooks export more instance data in the environment, which helps if |
198 | 7faf5110 | Michael Hanselmann | hook scripts need to take action based on the instance's properties |
199 | 7faf5110 | Michael Hanselmann | (no longer need to query back into ganeti) |
200 | 61b5e342 | Michael Hanselmann | - instance failovers when the instance is stopped do not check for free |
201 | 61b5e342 | Michael Hanselmann | RAM, so that failing over a stopped instance is possible in low memory |
202 | 61b5e342 | Michael Hanselmann | situations |
203 | 61b5e342 | Michael Hanselmann | - rapi uses queries for tags instead of jobs (for less job traffic), and |
204 | 61b5e342 | Michael Hanselmann | for cluster tags it won't talk to masterd at all but read them from |
205 | 61b5e342 | Michael Hanselmann | ssconf |
206 | 61b5e342 | Michael Hanselmann | - a couple of error handling fixes in RAPI |
207 | 61b5e342 | Michael Hanselmann | - drbd handling: improved the error handling of inconsistent disks after |
208 | 61b5e342 | Michael Hanselmann | resync to reduce the frequency of "there are some degraded disks for |
209 | 61b5e342 | Michael Hanselmann | this instance" messages |
210 | 61b5e342 | Michael Hanselmann | - fixed a bug in live migration when DRBD doesn't want to reconnect (the |
211 | 61b5e342 | Michael Hanselmann | error handling path called a wrong function name) |
212 | 61b5e342 | Michael Hanselmann | |
213 | 0dea942c | Iustin Pop | |

224 | 61b5e342 | Michael Hanselmann | - fix ``gnt-cluster getmaster`` on non-master nodes (regression) |
225 | 61b5e342 | Michael Hanselmann | - some small improvements to RAPI and IAllocator |
226 | 61b5e342 | Michael Hanselmann | - make watcher automatically start the master daemon if down |
227 | 61b5e342 | Michael Hanselmann | |

229 | d1908b41 | Iustin Pop | Version 2.0 release candidate 4 |
230 | 61b5e342 | Michael Hanselmann | ------------------------------- |
231 | 61b5e342 | Michael Hanselmann | |
232 | 61b5e342 | Michael Hanselmann | - change the OS list to not require locks; this helps with big clusters |
233 | 61b5e342 | Michael Hanselmann | - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the |
234 | 61b5e342 | Michael Hanselmann | volume group is broken |
235 | 61b5e342 | Michael Hanselmann | - ``gnt-instance info``, without any arguments, doesn't run for all |
236 | 61b5e342 | Michael Hanselmann | instances anymore; either pass ``--all`` or pass the desired |
237 | 61b5e342 | Michael Hanselmann | instances; this helps against mistakes on big clusters where listing |
238 | 61b5e342 | Michael Hanselmann | the information for all instances takes a long time |
239 | 61b5e342 | Michael Hanselmann | - miscellaneous doc and man pages fixes |

244 | 61b5e342 | Michael Hanselmann | |
245 | 61b5e342 | Michael Hanselmann | - Change the internal locking model of some ``gnt-node`` commands, in |
246 | 61b5e342 | Michael Hanselmann | order to reduce contention (and blocking of master daemon) when |
247 | 61b5e342 | Michael Hanselmann | batching many creation/reinstall jobs |
248 | 61b5e342 | Michael Hanselmann | - Fixes to Xen soft reboot |
249 | 61b5e342 | Michael Hanselmann | - No longer build documentation at build time, instead distribute it in |
250 | 61b5e342 | Michael Hanselmann | the archive, in order to reduce the need for the whole docbook/rst |
251 | 61b5e342 | Michael Hanselmann | toolchains |

267 | 61b5e342 | Michael Hanselmann | |
268 | 61b5e342 | Michael Hanselmann | - More documentation updates, now all docs should be more-or-less |
269 | 61b5e342 | Michael Hanselmann | up-to-date |
270 | 61b5e342 | Michael Hanselmann | - A couple of small fixes (mixed hypervisor clusters, offline nodes, |
271 | 61b5e342 | Michael Hanselmann | etc.) |
272 | 61b5e342 | Michael Hanselmann | - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM |
273 | 61b5e342 | Michael Hanselmann | and KVM) |

277 | 2fb85b64 | Iustin Pop | Version 2.0 beta 2 |
278 | 61b5e342 | Michael Hanselmann | ------------------ |
279 | 61b5e342 | Michael Hanselmann | |
280 | 61b5e342 | Michael Hanselmann | - Xen PVM and KVM have switched the default value for the instance root |
281 | 61b5e342 | Michael Hanselmann | disk to the first partition on the first drive, instead of the whole |
282 | 61b5e342 | Michael Hanselmann | drive; this means that the OS installation scripts must be changed |
283 | 61b5e342 | Michael Hanselmann | accordingly |
284 | 61b5e342 | Michael Hanselmann | - Man pages have been updated |
285 | 61b5e342 | Michael Hanselmann | - RAPI has been switched by default to HTTPS, and the exported functions |
286 | 61b5e342 | Michael Hanselmann | should all work correctly |
287 | 61b5e342 | Michael Hanselmann | - RAPI v1 has been removed |
288 | 61b5e342 | Michael Hanselmann | - Many improvements to the KVM hypervisor |
289 | 61b5e342 | Michael Hanselmann | - Block device errors are now better reported |

292 | 2fb85b64 | Iustin Pop | |
293 | 10f31783 | Iustin Pop | Version 2.0 beta 1 |
294 | 61b5e342 | Michael Hanselmann | ------------------ |
295 | 61b5e342 | Michael Hanselmann | |
296 | 61b5e342 | Michael Hanselmann | - Version 2 is a general rewrite of the code and therefore the |
297 | 61b5e342 | Michael Hanselmann | differences are too many to list, see the design document for 2.0 in |
298 | 61b5e342 | Michael Hanselmann | the ``doc/`` subdirectory for more details |
299 | 61b5e342 | Michael Hanselmann | - In this beta version there is not yet a migration path from 1.2 (there |
300 | 61b5e342 | Michael Hanselmann | will be one in the final 2.0 release) |
301 | 61b5e342 | Michael Hanselmann | - A few significant changes are: |
302 | 61b5e342 | Michael Hanselmann | |
303 | 61b5e342 | Michael Hanselmann | - all commands are executed by a daemon (``ganeti-masterd``) and the |
304 | 61b5e342 | Michael Hanselmann | various ``gnt-*`` commands are just front-ends to it |
305 | 7faf5110 | Michael Hanselmann | - all the commands are entered into, and executed from a job queue, |
306 | 7faf5110 | Michael Hanselmann | see the ``gnt-job(8)`` manpage |
307 | 7faf5110 | Michael Hanselmann | - the RAPI daemon supports read-write operations, secured by basic |
308 | 7faf5110 | Michael Hanselmann | HTTP authentication on top of HTTPS |
309 | 61b5e342 | Michael Hanselmann | - DRBD version 0.7 support has been removed, DRBD 8 is the only |
310 | 61b5e342 | Michael Hanselmann | supported version (when migrating from Ganeti 1.2 to 2.0, you need |
311 | 61b5e342 | Michael Hanselmann | to migrate to DRBD 8 first while still running Ganeti 1.2) |
312 | 61b5e342 | Michael Hanselmann | - DRBD devices are using statically allocated minor numbers, which |
313 | 61b5e342 | Michael Hanselmann | will be assigned to existing instances during the migration process |
314 | 61b5e342 | Michael Hanselmann | - there is support for both Xen PVM and Xen HVM instances running on |
315 | 61b5e342 | Michael Hanselmann | the same cluster |
316 | 61b5e342 | Michael Hanselmann | - KVM virtualization is supported too |
317 | 61b5e342 | Michael Hanselmann | - file-based storage has been implemented, which means that it is |
318 | 61b5e342 | Michael Hanselmann | possible to run the cluster without LVM and DRBD storage, for |
319 | 61b5e342 | Michael Hanselmann | example using a shared filesystem exported from shared storage (and |
320 | 61b5e342 | Michael Hanselmann | still have live migration) |
321 | 61b5e342 | Michael Hanselmann | |
322 | 10f31783 | Iustin Pop | |
323 | 10f31783 | Iustin Pop | Version 1.2.7 |
324 | 61b5e342 | Michael Hanselmann | ------------- |
325 | 61b5e342 | Michael Hanselmann | |
326 | 61b5e342 | Michael Hanselmann | - Change the default reboot type in ``gnt-instance reboot`` to "hard" |
327 | 61b5e342 | Michael Hanselmann | - Reuse the old instance mac address by default on instance import, if |
328 | 61b5e342 | Michael Hanselmann | the instance name is the same. |
329 | 7faf5110 | Michael Hanselmann | - Handle situations in which the node info rpc returns incomplete |
330 | 7faf5110 | Michael Hanselmann | results (issue 46) |
331 | 61b5e342 | Michael Hanselmann | - Add checks for tcp/udp ports collisions in ``gnt-cluster verify`` |

333 | 61b5e342 | Michael Hanselmann | |
334 | 61b5e342 | Michael Hanselmann | - state file support |
335 | 61b5e342 | Michael Hanselmann | - instance mac address support |
336 | 61b5e342 | Michael Hanselmann | - support for HVM clusters/instances |
337 | 61b5e342 | Michael Hanselmann | |
338 | 61b5e342 | Michael Hanselmann | - Add an option to show the number of cpu sockets and nodes in |
339 | 61b5e342 | Michael Hanselmann | ``gnt-node list`` |
340 | 61b5e342 | Michael Hanselmann | - Support OSes that handle more than one version of the OS api (but do |
341 | 61b5e342 | Michael Hanselmann | not change the current API in any other way) |
342 | 61b5e342 | Michael Hanselmann | - Fix ``gnt-node migrate`` |
343 | 61b5e342 | Michael Hanselmann | - ``gnt-debug`` man page |

346 | 61b5e342 | Michael Hanselmann | |
347 | 10f31783 | Iustin Pop | |
348 | 10f31783 | Iustin Pop | Version 1.2.6 |
349 | 61b5e342 | Michael Hanselmann | ------------- |
350 | 61b5e342 | Michael Hanselmann | |
351 | 61b5e342 | Michael Hanselmann | - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
352 | 61b5e342 | Michael Hanselmann | type of disk exported to fully virtualized instances. |
353 | 61b5e342 | Michael Hanselmann | - provide access to the serial console of HVM instances |
354 | 7faf5110 | Michael Hanselmann | - instance auto_balance flag, set by default. If turned off it will |
355 | 7faf5110 | Michael Hanselmann | avoid warnings on cluster verify if there is not enough memory to fail |
356 | 7faf5110 | Michael Hanselmann | over an instance. in the future it will prevent automatically failing |
357 | 7faf5110 | Michael Hanselmann | it over when we will support that. |
358 | 61b5e342 | Michael Hanselmann | - batcher tool for instance creation, see ``tools/README.batcher`` |
359 | 61b5e342 | Michael Hanselmann | - ``gnt-instance reinstall --select-os`` to interactively select a new |
360 | 61b5e342 | Michael Hanselmann | operating system when reinstalling an instance. |
361 | 61b5e342 | Michael Hanselmann | - when changing the memory amount on instance modify a check has been |
362 | 61b5e342 | Michael Hanselmann | added that the instance will be able to start. also warnings are |
363 | 61b5e342 | Michael Hanselmann | emitted if the instance will not be able to fail over, if auto_balance |
364 | 61b5e342 | Michael Hanselmann | is true. |
365 | 61b5e342 | Michael Hanselmann | - documentation fixes |
366 | 61b5e342 | Michael Hanselmann | - sync fields between ``gnt-instance list/modify/add/import`` |
367 | 61b5e342 | Michael Hanselmann | - fix a race condition in drbd when the sync speed was set after giving |
368 | 61b5e342 | Michael Hanselmann | the device a remote peer. |
369 | 61b5e342 | Michael Hanselmann | |
370 | 10f31783 | Iustin Pop | |
371 | 10f31783 | Iustin Pop | Version 1.2.5 |
372 | 61b5e342 | Michael Hanselmann | ------------- |
373 | 61b5e342 | Michael Hanselmann | |
374 | 61b5e342 | Michael Hanselmann | - note: the allowed size and number of tags per object were reduced |
375 | 61b5e342 | Michael Hanselmann | - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups |
376 | 61b5e342 | Michael Hanselmann | - fixed twisted 8.x compatibility |

378 | 61b5e342 | Michael Hanselmann | - add TCP keepalives on twisted connections to detect restarted nodes |
379 | 61b5e342 | Michael Hanselmann | - disk increase support, see ``gnt-instance grow-disk`` |
380 | 61b5e342 | Michael Hanselmann | - implement bulk node/instance query for RAPI |
381 | 61b5e342 | Michael Hanselmann | - add tags in node/instance listing (optional) |
382 | 61b5e342 | Michael Hanselmann | - experimental migration (and live migration) support, read the man page |
383 | 61b5e342 | Michael Hanselmann | for ``gnt-instance migrate`` |
384 | 61b5e342 | Michael Hanselmann | - the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
385 | 61b5e342 | Michael Hanselmann | has some small improvements in handling its state file |
386 | 61b5e342 | Michael Hanselmann | |
387 | 10f31783 | Iustin Pop | |
388 | 10f31783 | Iustin Pop | Version 1.2.4 |
389 | 61b5e342 | Michael Hanselmann | ------------- |
390 | 61b5e342 | Michael Hanselmann | |
391 | 61b5e342 | Michael Hanselmann | - Experimental readonly, REST-based remote API implementation; |
392 | 61b5e342 | Michael Hanselmann | automatically started on master node, TCP port 5080, if enabled by |
393 | 61b5e342 | Michael Hanselmann | ``--enable-rapi`` parameter to configure script. |
394 | 61b5e342 | Michael Hanselmann | - Instance allocator support. Add and import instance accept a |
395 | 61b5e342 | Michael Hanselmann | ``--iallocator`` parameter, and call that instance allocator to decide |
396 | 61b5e342 | Michael Hanselmann | which node to use for the instance. The iallocator document describes |
397 | 61b5e342 | Michael Hanselmann | what's expected from an allocator script. |
398 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
399 | 61b5e342 | Michael Hanselmann | ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
400 | 61b5e342 | Michael Hanselmann | node is lost there is still enough memory to fail over the instances |
401 | 61b5e342 | Michael Hanselmann | that reside on it. |
402 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
403 | 61b5e342 | Michael Hanselmann | ``gnt-cluster verify``, to check for site-specific compliance. All the |
404 | 61b5e342 | Michael Hanselmann | hooks will run, and their output, if any, will be displayed. Any |
405 | 61b5e342 | Michael Hanselmann | failing hook will make the verification return an error value. |
406 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` now checks that its peers are reachable on the |
407 | 61b5e342 | Michael Hanselmann | primary and secondary interfaces |
408 | 61b5e342 | Michael Hanselmann | - ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
409 | 61b5e342 | Michael Hanselmann | that is still declared as part of the cluster and has failed. |
410 | 61b5e342 | Michael Hanselmann | - ``gnt-* list`` commands now accept a new ``-o +field`` way of |
411 | 61b5e342 | Michael Hanselmann | specifying output fields, that just adds the chosen fields to the |
412 | 61b5e342 | Michael Hanselmann | default ones. |
413 | 61b5e342 | Michael Hanselmann | - ``gnt-backup`` now has a new ``remove`` command to delete an existing |
414 | 61b5e342 | Michael Hanselmann | export from the filesystem. |
415 | 61b5e342 | Michael Hanselmann | - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
416 | 61b5e342 | Michael Hanselmann | have been added. Using them you can enable/disable acpi and pae |
417 | 61b5e342 | Michael Hanselmann | support, and specify a path for a cd image to be exported to the |
418 | 61b5e342 | Michael Hanselmann | instance. These parameters as the name suggest only work on HVM |
419 | 61b5e342 | Michael Hanselmann | clusters. |
420 | 61b5e342 | Michael Hanselmann | - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
421 | 61b5e342 | Michael Hanselmann | PAE support will be set to the previously hardcoded values, but the |
422 | 61b5e342 | Michael Hanselmann | (previously hardcoded) path to the CDROM ISO image will be unset and |
423 | 61b5e342 | Michael Hanselmann | if required, needs to be set manually with ``gnt-instance modify`` |
424 | 61b5e342 | Michael Hanselmann | after the upgrade. |
425 | 61b5e342 | Michael Hanselmann | - The address to which an instance's VNC console is bound is now |
426 | 61b5e342 | Michael Hanselmann | selectable per-instance, rather than being cluster wide. Of course |
427 | 61b5e342 | Michael Hanselmann | this only applies to instances controlled via VNC, so currently just |
428 | 61b5e342 | Michael Hanselmann | applies to HVM clusters. |
429 | 61b5e342 | Michael Hanselmann | |

434 | 61b5e342 | Michael Hanselmann | - more tweaks to the disk activation code (especially helpful for DRBD) |
435 | 61b5e342 | Michael Hanselmann | - change the default ``gnt-instance list`` output format, now there is |
436 | 61b5e342 | Michael Hanselmann | one combined status field (see the manpage for the exact values this |
437 | 61b5e342 | Michael Hanselmann | field will have) |
438 | 61b5e342 | Michael Hanselmann | - some more fixes for the mac export to hooks change |
439 | 61b5e342 | Michael Hanselmann | - make Ganeti not break with DRBD 8.2.x (which changed the version |
440 | 61b5e342 | Michael Hanselmann | format in ``/proc/drbd``) (issue 24) |
441 | 61b5e342 | Michael Hanselmann | - add an upgrade tool from "remote_raid1" disk template to "drbd" disk |
442 | 61b5e342 | Michael Hanselmann | template, allowing migration from DRBD0.7+MD to DRBD8 |
443 | 61b5e342 | Michael Hanselmann | |
