Version 2.8.0 beta1 |
6 |
------------------- |
7 |
|
8 |
*(unreleased)* |
9 |
|
10 |
- The minimum Python version needed to run Ganeti is now 2.6. |
11 |
- The :doc:`Remote API <rapi>` daemon now supports a command line flag |
12 |
to always require authentication, ``--require-authentication``. It can |
13 |
be specified in ``$sysconfdir/default/ganeti``. |
14 |
- A new cluster attribute 'enabled_disk_templates' is introduced. It will |
15 |
be used to manage the disk templates to be used by instances in the cluster. |
16 |
Initially, it will be set to a list that includes plain, drbd, if they were |
17 |
enabled by specifying a volume group name, and file and sharedfile, if those |
18 |
were enabled at configure time. Additionally, it will include all disk |
19 |
templates that are currently used by instances. The order of disk templates |
20 |
will be based on Ganeti's history of supporting them. In the future, the |
21 |
first entry of the list will be used as a default disk template on instance |
22 |
creation. |
23 |
- ``cfgupgrade`` now supports a ``--downgrade`` option to bring the |
24 |
configuration back to the previous stable version. |
25 |
|
26 |
|
27 |
Version 2.7.0 beta1 |
28 |
------------------- |
29 |
|
30 |
*(Released Wed, 6 Feb 2013)* |
31 |
|
32 |
- ``gnt-instance batch-create`` has been changed to use the bulk create |
33 |
opcode from Ganeti. This lead to incompatible changes in the format of |
34 |
the JSON file. It's now not a custom dict anymore but a dict |
35 |
compatible with the ``OpInstanceCreate`` opcode. |
36 |
- Parent directories for file storage need to be listed in |
37 |
``$sysconfdir/ganeti/file-storage-paths`` now. ``cfgupgrade`` will |
38 |
write the file automatically based on old configuration values, but it |
39 |
can not distribute it across all nodes and the file contents should be |
40 |
verified. Use ``gnt-cluster copyfile |
41 |
$sysconfdir/ganeti/file-storage-paths`` once the cluster has been |
42 |
upgraded. The reason for requiring this list of paths now is that |
43 |
before it would have been possible to inject new paths via RPC, |
44 |
allowing files to be created in arbitrary locations. The RPC protocol |
45 |
is protected using SSL/X.509 certificates, but as a design principle |
46 |
Ganeti does not permit arbitrary paths to be passed. |
47 |
- The parsing of the variants file for OSes (see |
48 |
:manpage:`ganeti-os-interface(7)`) has been slightly changed: now empty |
49 |
lines and comment lines (starting with ``#``) are ignored for better |
50 |
readability. |
51 |
- The ``setup-ssh`` tool added in Ganeti 2.2 has been replaced and is no |
52 |
longer available. ``gnt-node add`` now invokes a new tool on the |
53 |
destination node, named ``prepare-node-join``, to configure the SSH |
54 |
daemon. Paramiko is no longer necessary to configure nodes' SSH |
55 |
daemons via ``gnt-node add``. |
56 |
- A new user option, :pyeval:`rapi.RAPI_ACCESS_READ`, has been added |
57 |
for RAPI users. It allows granting permissions to query for |
58 |
information to a specific user without giving |
59 |
:pyeval:`rapi.RAPI_ACCESS_WRITE` permissions. |
60 |
- A new tool named ``node-cleanup`` has been added. It cleans remains of |
61 |
a cluster from a machine by stopping all daemons, removing |
62 |
certificates and ssconf files. Unless the ``--no-backup`` option is |
63 |
given, copies of the certificates are made. |
64 |
- Draining (``gnt-cluster queue drain``) and un-draining the job queue |
65 |
(``gnt-cluster queue undrain``) now affects all nodes in a cluster and |
66 |
the flag is not reset after a master failover. |
67 |
- Instance creations now support the use of opportunistic locking, |
68 |
potentially speeding up the (parallel) creation of multiple instances. |
69 |
This feature is currently only available via the :doc:`RAPI |
70 |
<rapi>` interface and when an instance allocator is used. If the |
71 |
``opportunistic_locking`` parameter is set the opcode will try to |
72 |
acquire as many locks as possible, but will not wait for any locks |
73 |
held by other opcodes. If not enough resources can be found to |
74 |
allocate the instance, the temporary error code |
75 |
:pyeval:`errors.ECODE_TEMP_NORES` is returned. The operation can be |
76 |
retried thereafter, with or without opportunistic locking. |
77 |
- The functionality for allocating multiple instances at once has been |
78 |
overhauled and is now also available through :doc:`RAPI <rapi>`. |
79 |
- Man pages can now be included when the documentation is built, in |
80 |
which case the output is in ``doc/man-html``. The configure-time |
81 |
option is ``--enable-manpages-in-doc``. Sphinx 1.0 or higher is |
82 |
required. |
83 |
- A new htool called ``hroller`` helps scheduling parallel shutdown of |
84 |
nodes on clusters where all instances are shut down, but without ever |
85 |
rebooting both primary and secondary node for an instance at the same |
86 |
time. |
87 |
- Queries not needing locks or RPC access to the node can now be |
88 |
performed by the confd daemon, making them independent from jobs, and |
89 |
thus faster to execute. This is selectable at configure time. |
90 |
- The KVM hypervisor has been updated with many new hypervisor |
91 |
parameters, including a generic one for passing arbitrary command line |
92 |
values. See a complete list in :manpage:`gnt-instance(8)`. |
93 |
- A new tool, called ``mon-collector``, is the stand-alone executor of |
94 |
the data collectors for a monitoring system. As of this version, it |
95 |
just includes the DRBD data collector, that can be executed by calling |
96 |
``mon-collector`` using the ``drbd`` parameter. See |
97 |
:manpage:`mon-collector(7)`. |
98 |
- New ``exclusive-storage`` node parameter added. When it's set to true, |
99 |
physical disks are assigned in an exclusive fashion to instances, as |
100 |
documented in :doc:`Partitioned Ganeti <design-partitioned>`. |
101 |
Currently, only instances using the ``plain`` disk template are |
102 |
supported. |
103 |
- New network management functionality to support automatic allocation |
104 |
of IP addresses and managing of network parameters. See |
105 |
:manpage:`gnt-network(8)` for more details. |
106 |
- New external storage backend, to allow managing arbitrary storage |
107 |
systems external to the cluster. See |
108 |
:manpage:`ganeti-extstorage-interface(7)`. |
109 |
- Instance renames of LVM-based instances will now update the LV tags |
110 |
(which can be used to recover the instance-to-LV mapping in case of |
111 |
emergencies) |
112 |
- ``hbal`` will now exit with status 0 if, during job execution over |
113 |
LUXI, early exit has been requested and all jobs are successful; |
114 |
before, exit status 1 was used, which cannot be differentiated from |
115 |
"job error" case |
116 |
|
117 |
|
118 |
Version 2.6.2 |
119 |
------------- |
120 |
|
121 |
*(Released Fri, 21 Dec 2012)* |
122 |
|
123 |
Important behaviour change: hbal won't rebalance anymore instances which |
124 |
have the ``auto_balance`` attribute set to false. This was the intention |
125 |
all along, but until now it only skipped those from the N+1 memory |
126 |
reservation (DRBD-specific). |
127 |
|
128 |
A significant number of bug fixes in this release: |
129 |
|
130 |
- Fixed disk adoption interaction with ipolicy checks. |
131 |
- Fixed networking issues when instances are started, stopped or |
132 |
migrated, by forcing the tap device's MAC prefix to "fe" (issue 217). |
133 |
- Fixed the warning in cluster verify for shared storage instances not |
134 |
being redundant. |
135 |
- Fixed removal of storage directory on shared file storage (issue 262). |
136 |
- Fixed validation of LVM volume group name in OpClusterSetParams |
137 |
(``gnt-cluster modify``) (issue 285). |
138 |
- Fixed runtime memory increases (``gnt-instance modify -m``). |
139 |
- Fixed live migration under Xen's ``xl`` mode. |
140 |
- Fixed ``gnt-instance console`` with ``xl``. |
141 |
- Fixed building with newer Haskell compiler/libraries. |
142 |
- Fixed PID file writing in Haskell daemons (confd); this prevents |
143 |
restart issues if confd was launched manually (outside of |
144 |
``daemon-util``) while another copy of it was running |
145 |
- Fixed a type error when doing live migrations with KVM (issue 297) and |
146 |
the error messages for failing migrations have been improved. |
147 |
- Fixed opcode validation for the out-of-band commands (``gnt-node |
148 |
power``). |
149 |
- Fixed a type error when unsetting OS hypervisor parameters (issue |
150 |
311); now it's possible to unset all OS-specific hypervisor |
151 |
parameters. |
152 |
- Fixed the ``dry-run`` mode for many operations: verification of |
153 |
results was over-zealous but didn't take into account the ``dry-run`` |
154 |
operation, resulting in "wrong" failures. |
155 |
- Fixed bash completion in ``gnt-job list`` when the job queue has |
156 |
hundreds of entries; especially with older ``bash`` versions, this |
157 |
results in significant CPU usage. |
158 |
|
159 |
And lastly, a few other improvements have been made: |
160 |
|
161 |
- Added option to force master-failover without voting (issue 282). |
162 |
- Clarified error message on lock conflict (issue 287). |
163 |
- Logging of newly submitted jobs has been improved (issue 290). |
164 |
- Hostname checks have been made uniform between instance rename and |
165 |
create (issue 291). |
166 |
- The ``--submit`` option is now supported by ``gnt-debug delay``. |
167 |
- Shutting down the master daemon by sending SIGTERM now stops it from |
168 |
processing jobs waiting for locks; instead, those jobs will be started |
169 |
once again after the master daemon is started the next time (issue |
170 |
296). |
171 |
- Support for Xen's ``xl`` program has been improved (besides the fixes |
172 |
above). |
173 |
- Reduced logging noise in the Haskell confd daemon (only show one log |
174 |
entry for each config reload, instead of two). |
175 |
- Several man page updates and typo fixes. |
176 |
|
177 |
|
178 |
Version 2.6.1 |
179 |
------------- |
180 |
|
181 |
*(Released Fri, 12 Oct 2012)* |
182 |
|
183 |
A small bugfix release. Among the bugs fixed: |
184 |
|
185 |
- Fixed double use of ``PRIORITY_OPT`` in ``gnt-node migrate``, that |
186 |
made the command unusable. |
187 |
- Commands that issue many jobs don't fail anymore just because some jobs |
188 |
take so long that other jobs are archived. |
189 |
- Failures during ``gnt-instance reinstall`` are reflected by the exit |
190 |
status. |
191 |
- Issue 190 fixed. Check for DRBD in cluster verify is enabled only when |
192 |
DRBD is enabled. |
193 |
- When ``always_failover`` is set, ``--allow-failover`` is not required |
194 |
in migrate commands anymore. |
195 |
- ``bash_completion`` works even if extglob is disabled. |
196 |
- Fixed bug with locks that made failover for RDB-based instances fail. |
197 |
- Fixed bug in non-mirrored instance allocation that made Ganeti choose |
198 |
a random node instead of one based on the allocator metric. |
199 |
- Support for newer versions of pylint and pep8. |
200 |
- Hail doesn't fail anymore when trying to add an instance of type |
201 |
``file``, ``sharedfile`` or ``rbd``. |
202 |
- Added new Makefile target to rebuild the whole distribution, so that |
203 |
all files are included. |

Version 2.6.0 |
207 |
------------- |
208 |
|
209 |
*(Released Fri, 27 Jul 2012)* |
210 |
|
211 |
|
212 |
.. attention:: The ``LUXI`` protocol has been made more consistent |
213 |
regarding its handling of command arguments. This, however, leads to |
214 |
incompatibility issues with previous versions. Please ensure that you |
215 |
restart Ganeti daemons soon after the upgrade, otherwise most |
216 |
``LUXI`` calls (job submission, setting/resetting the drain flag, |
217 |
pausing/resuming the watcher, cancelling and archiving jobs, querying |
218 |
the cluster configuration) will fail. |
219 |
|
220 |
|
221 |
New features |
222 |
~~~~~~~~~~~~ |
223 |
|
224 |
Instance run status |
225 |
+++++++++++++++++++ |
226 |
|
227 |
The current ``admin_up`` field, which used to denote whether an instance |
228 |
should be running or not, has been removed. Instead, ``admin_state`` is |
229 |
introduced, with 3 possible values -- ``up``, ``down`` and ``offline``. |
230 |
|
231 |
The rational behind this is that an instance being “down” can have |
232 |
different meanings: |
233 |
|
234 |
- it could be down during a reboot |
235 |
- it could be temporarily be down for a reinstall |
236 |
- or it could be down because it is deprecated and kept just for its |
237 |
disk |
238 |
|
239 |
The previous Boolean state was making it difficult to do capacity |
240 |
calculations: should Ganeti reserve memory for a down instance? Now, the |
241 |
tri-state field makes it clear: |
242 |
|
243 |
- in ``up`` and ``down`` state, all resources are reserved for the |
244 |
instance, and it can be at any time brought up if it is down |
245 |
- in ``offline`` state, only disk space is reserved for it, but not |
246 |
memory or CPUs |
247 |
|
248 |
The field can have an extra use: since the transition between ``up`` and |
249 |
``down`` and vice-versus is done via ``gnt-instance start/stop``, but |
250 |
transition between ``offline`` and ``down`` is done via ``gnt-instance |
251 |
modify``, it is possible to given different rights to users. For |
252 |
example, owners of an instance could be allowed to start/stop it, but |
253 |
not transition it out of the offline state. |
254 |
|
255 |
Instance policies and specs |
256 |
+++++++++++++++++++++++++++ |
257 |
|
258 |
In previous Ganeti versions, an instance creation request was not |
259 |
limited on the minimum size and on the maximum size just by the cluster |
260 |
resources. As such, any policy could be implemented only in third-party |
261 |
clients (RAPI clients, or shell wrappers over ``gnt-*`` |
262 |
tools). Furthermore, calculating cluster capacity via ``hspace`` again |
263 |
required external input with regards to instance sizes. |
264 |
|
265 |
In order to improve these workflows and to allow for example better |
266 |
per-node group differentiation, we introduced instance specs, which |
267 |
allow declaring: |
268 |
|
269 |
- minimum instance disk size, disk count, memory size, cpu count |
270 |
- maximum values for the above metrics |
271 |
- and “standard” values (used in ``hspace`` to calculate the standard |
272 |
sized instances) |
273 |
|
274 |
The minimum/maximum values can be also customised at node-group level, |
275 |
for example allowing more powerful hardware to support bigger instance |
276 |
memory sizes. |
277 |
|
278 |
Beside the instance specs, there are a few other settings belonging to |
279 |
the instance policy framework. It is possible now to customise, per |
280 |
cluster and node-group: |
281 |
|
282 |
- the list of allowed disk templates |
283 |
- the maximum ratio of VCPUs per PCPUs (to control CPU oversubscription) |
284 |
- the maximum ratio of instance to spindles (see below for more |
285 |
information) for local storage |
286 |
|
287 |
All these together should allow all tools that talk to Ganeti to know |
288 |
what are the ranges of allowed values for instances and the |
289 |
over-subscription that is allowed. |
290 |
|
291 |
For the VCPU/PCPU ratio, we already have the VCPU configuration from the |
292 |
instance configuration, and the physical CPU configuration from the |
293 |
node. For the spindle ratios however, we didn't track before these |
294 |
values, so new parameters have been added: |
295 |
|
296 |
- a new node parameter ``spindle_count``, defaults to 1, customisable at |
297 |
node group or node level |
298 |
- at new backend parameter (for instances), ``spindle_use`` defaults to 1 |
299 |
|
300 |
Note that spindles in this context doesn't need to mean actual |
301 |
mechanical hard-drives; it's just a relative number for both the node |
302 |
I/O capacity and instance I/O consumption. |
303 |
|
304 |
Instance migration behaviour |
305 |
++++++++++++++++++++++++++++ |
306 |
|
307 |
While live-migration is in general desirable over failover, it is |
308 |
possible that for some workloads it is actually worse, due to the |
309 |
variable time of the “suspend” phase during live migration. |
310 |
|
311 |
To allow the tools to work consistently over such instances (without |
312 |
having to hard-code instance names), a new backend parameter |
313 |
``always_failover`` has been added to control the migration/failover |
314 |
behaviour. When set to True, all migration requests for an instance will |
315 |
instead fall-back to failover. |
316 |
|
317 |
Instance memory ballooning |
318 |
++++++++++++++++++++++++++ |
319 |
|
320 |
Initial support for memory ballooning has been added. The memory for an |
321 |
instance is no longer fixed (backend parameter ``memory``), but instead |
322 |
can vary between minimum and maximum values (backend parameters |
323 |
``minmem`` and ``maxmem``). Currently we only change an instance's |
324 |
memory when: |
325 |
|
326 |
- live migrating or failing over and instance and the target node |
327 |
doesn't have enough memory |
328 |
- user requests changing the memory via ``gnt-instance modify |
329 |
--runtime-memory`` |
330 |
|
331 |
Instance CPU pinning |
332 |
++++++++++++++++++++ |
333 |
|
334 |
In order to control the use of specific CPUs by instance, support for |
335 |
controlling CPU pinning has been added for the Xen, HVM and LXC |
336 |
hypervisors. This is controlled by a new hypervisor parameter |
337 |
``cpu_mask``; details about possible values for this are in the |
338 |
:manpage:`gnt-instance(8)`. Note that use of the most specific (precise |
339 |
VCPU-to-CPU mapping) form will work well only when all nodes in your |
340 |
cluster have the same amount of CPUs. |
341 |
|
342 |
Disk parameters |
343 |
+++++++++++++++ |
344 |
|
345 |
Another area in which Ganeti was not customisable were the parameters |
346 |
used for storage configuration, e.g. how many stripes to use for LVM, |
347 |
DRBD resync configuration, etc. |
348 |
|
349 |
To improve this area, we've added disks parameters, which are |
350 |
customisable at cluster and node group level, and which allow to |
351 |
specify various parameters for disks (DRBD has the most parameters |
352 |
currently), for example: |
353 |
|
354 |
- DRBD resync algorithm and parameters (e.g. speed) |
355 |
- the default VG for meta-data volumes for DRBD |
356 |
- number of stripes for LVM (plain disk template) |
357 |
- the RBD pool |
358 |
|
359 |
These parameters can be modified via ``gnt-cluster modify -D …`` and |
360 |
``gnt-group modify -D …``, and are used at either instance creation (in |
361 |
case of LVM stripes, for example) or at disk “activation” time |
362 |
(e.g. resync speed). |
363 |
|
364 |
Rados block device support |
365 |
++++++++++++++++++++++++++ |
366 |
|
367 |
A Rados (http://ceph.com/wiki/Rbd) storage backend has been added, |
368 |
denoted by the ``rbd`` disk template type. This is considered |
369 |
experimental, feedback is welcome. For details on configuring it, see |
370 |
the :doc:`install` document and the :manpage:`gnt-cluster(8)` man page. |
371 |
|
372 |
Master IP setup |
373 |
+++++++++++++++ |
374 |
|
375 |
The existing master IP functionality works well only in simple setups (a |
376 |
single network shared by all nodes); however, if nodes belong to |
377 |
different networks, then the ``/32`` setup and lack of routing |
378 |
information is not enough. |
379 |
|
380 |
To allow the master IP to function well in more complex cases, the |
381 |
system was reworked as follows: |
382 |
|
383 |
- a master IP netmask setting has been added |
384 |
- the master IP activation/turn-down code was moved from the node daemon |
385 |
to a separate script |
386 |
- whether to run the Ganeti-supplied master IP script or a user-supplied |
387 |
on is a ``gnt-cluster init`` setting |
388 |
|
389 |
Details about the location of the standard and custom setup scripts are |
390 |
in the man page :manpage:`gnt-cluster(8)`; for information about the |
391 |
setup script protocol, look at the Ganeti-supplied script. |
392 |
|
393 |
SPICE support |
394 |
+++++++++++++ |
395 |
|
396 |
The `SPICE <http://www.linux-kvm.org/page/SPICE>`_ support has been |
397 |
improved. |
398 |
|
399 |
It is now possible to use TLS-protected connections, and when renewing |
400 |
or changing the cluster certificates (via ``gnt-cluster renew-crypto``, |
401 |
it is now possible to specify spice or spice CA certificates. Also, it |
402 |
is possible to configure a password for SPICE sessions via the |
403 |
hypervisor parameter ``spice_password_file``. |
404 |
|
405 |
There are also new parameters to control the compression and streaming |
406 |
options (e.g. ``spice_image_compression``, ``spice_streaming_video``, |
407 |
etc.). For details, see the man page :manpage:`gnt-instance(8)` and look |
408 |
for the spice parameters. |
409 |
|
410 |
Lastly, it is now possible to see the SPICE connection information via |
411 |
``gnt-instance console``. |
412 |
|
413 |
OVF converter |
414 |
+++++++++++++ |
415 |
|
416 |
A new tool (``tools/ovfconverter``) has been added that supports |
417 |
conversion between Ganeti and the `Open Virtualization Format |
418 |
<http://en.wikipedia.org/wiki/Open_Virtualization_Format>`_ (both to and |
419 |
from). |
420 |
|
421 |
This relies on the ``qemu-img`` tool to convert the disk formats, so the |
422 |
actual compatibility with other virtualization solutions depends on it. |
423 |
|
424 |
Confd daemon changes |
425 |
++++++++++++++++++++ |
426 |
|
427 |
The configuration query daemon (``ganeti-confd``) is now optional, and |
428 |
has been rewritten in Haskell; whether to use the daemon at all, use the |
429 |
Python (default) or the Haskell version is selectable at configure time |
430 |
via the ``--enable-confd`` parameter, which can take one of the |
431 |
``haskell``, ``python`` or ``no`` values. If not used, disabling the |
432 |
daemon will result in a smaller footprint; for larger systems, we |
433 |
welcome feedback on the Haskell version which might become the default |
434 |
in future versions. |
435 |
|
436 |
If you want to use ``gnt-node list-drbd`` you need to have the Haskell |
437 |
daemon running. The Python version doesn't implement the new call. |
438 |
|
439 |
|
440 |
User interface changes |
441 |
~~~~~~~~~~~~~~~~~~~~~~ |
442 |
|
443 |
We have replaced the ``--disks`` option of ``gnt-instance |
444 |
replace-disks`` with a more flexible ``--disk`` option, which allows |
445 |
adding and removing disks at arbitrary indices (Issue 188). Furthermore, |
446 |
disk size and mode can be changed upon recreation (via ``gnt-instance |
447 |
recreate-disks``, which accepts the same ``--disk`` option). |
448 |
|
449 |
As many people are used to a ``show`` command, we have added that as an |
450 |
alias to ``info`` on all ``gnt-*`` commands. |
451 |
|
452 |
The ``gnt-instance grow-disk`` command has a new mode in which it can |
453 |
accept the target size of the disk, instead of the delta; this can be |
454 |
more safe since two runs in absolute mode will be idempotent, and |
455 |
sometimes it's also easier to specify the desired size directly. |
456 |
|
457 |
Also the handling of instances with regard to offline secondaries has |
458 |
been improved. Instance operations should not fail because one of it's |
459 |
secondary nodes is offline, even though it's safe to proceed. |
460 |
|
461 |
A new command ``list-drbd`` has been added to the ``gnt-node`` script to |
462 |
support debugging of DRBD issues on nodes. It provides a mapping of DRBD |
463 |
minors to instance name. |
464 |
|
465 |
API changes |
466 |
~~~~~~~~~~~ |
467 |
|
468 |
RAPI coverage has improved, with (for example) new resources for |
469 |
recreate-disks, node power-cycle, etc. |
470 |
|
471 |
Compatibility |
472 |
~~~~~~~~~~~~~ |
473 |
|
474 |
There is partial support for ``xl`` in the Xen hypervisor; feedback is |
475 |
welcome. |
476 |
|
477 |
Python 2.7 is better supported, and after Ganeti 2.6 we will investigate |
478 |
whether to still support Python 2.4 or move to Python 2.6 as minimum |
479 |
required version. |
480 |
|
481 |
Support for Fedora has been slightly improved; the provided example |
482 |
init.d script should work better on it and the INSTALL file should |
483 |
document the needed dependencies. |
484 |
|
485 |
Internal changes |
486 |
~~~~~~~~~~~~~~~~ |
487 |
|
488 |
The deprecated ``QueryLocks`` LUXI request has been removed. Use |
489 |
``Query(what=QR_LOCK, ...)`` instead. |
490 |
|
491 |
The LUXI requests :pyeval:`luxi.REQ_QUERY_JOBS`, |
492 |
:pyeval:`luxi.REQ_QUERY_INSTANCES`, :pyeval:`luxi.REQ_QUERY_NODES`, |
493 |
:pyeval:`luxi.REQ_QUERY_GROUPS`, :pyeval:`luxi.REQ_QUERY_EXPORTS` and |
494 |
:pyeval:`luxi.REQ_QUERY_TAGS` are deprecated and will be removed in a |
495 |
future version. :pyeval:`luxi.REQ_QUERY` should be used instead. |
496 |
|
497 |
RAPI client: ``CertificateError`` now derives from |
498 |
``GanetiApiError``. This should make it more easy to handle Ganeti |
499 |
errors. |
500 |
|
501 |
Deprecation warnings due to PyCrypto/paramiko import in |
502 |
``tools/setup-ssh`` have been silenced, as usually they are safe; please |
503 |
make sure to run an up-to-date paramiko version, if you use this tool. |
504 |
|
505 |
The QA scripts now depend on Python 2.5 or above (the main code base |
506 |
still works with Python 2.4). |
507 |
|
508 |
The configuration file (``config.data``) is now written without |
509 |
indentation for performance reasons; if you want to edit it, it can be |
510 |
re-formatted via ``tools/fmtjson``. |
511 |
|
512 |
A number of bugs has been fixed in the cluster merge tool. |
513 |
|
514 |
``x509`` certification verification (used in import-export) has been |
515 |
changed to allow the same clock skew as permitted by the cluster |
516 |
verification. This will remove some rare but hard to diagnose errors in |
517 |
import-export. |
518 |
|
519 |
|
520 |
Version 2.6.0 rc4 |
521 |

528 |
instance, fix CDROM booting for KVM instances) |
529 |
- fixed node group modification of node parameters |
530 |
- fixed issue in LUClusterVerifyGroup with multi-group clusters |
531 |
- fixed generation of bash completion to ensure a stable ordering |
532 |
- fixed a few typos |
533 |
|
534 |
|
535 |
Version 2.6.0 rc3 |
536 |
----------------- |
537 |
|
538 |
*(Released Fri, 13 Jul 2012)* |
539 |
|
540 |
Third release candidate for 2.6. The following changes were done from |

544 |
- Fixed an inconsistency in the LUXI protocol with the provided |
545 |
arguments (NOT backwards compatible) |
546 |
- Fixed a bug with node groups ipolicy where ``min`` was greater than |
547 |
the cluster ``std`` value |
548 |
- Implemented a new ``gnt-node list-drbd`` call to list DRBD minors for |
549 |
easier instance debugging on nodes (requires ``hconfd`` to work) |
550 |
|
551 |
|
552 |
Version 2.6.0 rc2 |
553 |
----------------- |
554 |
|
555 |
*(Released Tue, 03 Jul 2012)* |

566 |
commands which use activate disks internally: |
567 |
* ``gnt-instance start|reboot|rename|backup|export`` |
568 |
- Made it possible to remove safely an instance if its secondaries are |

Version 2.6.0 beta1 |
614 |
------------------- |
615 |
|
616 |
*(Released Wed, 23 May 2012)* |
617 |
|
618 |
First beta release of 2.6. The following changes were done from beta1 to |
619 |
beta2: |
620 |
|
621 |
- integrated patch for distributions without ``start-stop-daemon`` |
622 |
- adapted example init.d script to work on Fedora |
623 |
- fixed log handling in Haskell daemons |
624 |
- adapted checks in the watcher for pycurl linked against libnss |
625 |
- add partial support for ``xl`` instead of ``xm`` for Xen |
626 |
- fixed a type issue in cluster verification |
627 |
- fixed ssconf handling in the Haskell code (was breaking confd in IPv6 |
628 |
clusters) |
629 |
|
630 |
Plus integrated fixes from the 2.5 branch: |
631 |
|
632 |
- fixed ``kvm-ifup`` to use ``/bin/bash`` |
633 |
- fixed parallel build failures |
634 |
- KVM live migration when using a custom keymap |
635 |
|
636 |
|
637 |
Version 2.5.2 |
638 |
------------- |
639 |
|
640 |
*(Released Tue, 24 Jul 2012)* |
641 |
|
642 |
A small bugfix release, with no new features: |
643 |
|
644 |
- fixed bash-isms in kvm-ifup, for compatibility with systems which use a |
645 |
different default shell (e.g. Debian, Ubuntu) |
646 |
- fixed KVM startup and live migration with a custom keymap (fixes Issue |
647 |
243 and Debian bug #650664) |
648 |
- fixed compatibility with KVM versions that don't support multiple boot |
649 |
devices (fixes Issue 230 and Debian bug #624256) |
650 |
|
651 |
Additionally, a few fixes were done to the build system (fixed parallel |
652 |
build failures) and to the unittests (fixed race condition in test for |
653 |
FileID functions, and the default enable/disable mode for QA test is now |
654 |
customisable). |
655 |
|
656 |
|
657 |
Version 2.5.1 |
658 |
------------- |
659 |
|
660 |
*(Released Fri, 11 May 2012)* |
661 |
|
662 |
A small bugfix release. |
663 |
|
664 |
The main issues solved are on the topic of compatibility with newer LVM |
665 |
releases: |
666 |
|
667 |
- fixed parsing of ``lv_attr`` field |
668 |
- adapted to new ``vgreduce --removemissing`` behaviour where sometimes |
669 |
the ``--force`` flag is needed |
670 |
|
671 |
Also on the topic of compatibility, ``tools/lvmstrap`` has been changed |
672 |
to accept kernel 3.x too (was hardcoded to 2.6.*). |
673 |
|
674 |
A regression present in 2.5.0 that broke handling (in the gnt-* scripts) |
675 |
of hook results and that also made display of other errors suboptimal |
676 |
was fixed; the code behaves now like 2.4 and earlier. |
677 |
|
678 |
Another change in 2.5, the cleanup of the OS scripts environment, is too |
679 |
aggressive: it removed even the ``PATH`` variable, which requires the OS |
680 |
scripts to *always* need to export it. Since this is a bit too strict, |
681 |
we now export a minimal PATH, the same that we export for hooks. |
682 |
|
683 |
The fix for issue 201 (Preserve bridge MTU in KVM ifup script) was |
684 |
integrated into this release. |
685 |
|
686 |
Finally, a few other miscellaneous changes were done (no new features, |
687 |
just small improvements): |
688 |
|
689 |
- Fix ``gnt-group --help`` display |
690 |
- Fix hardcoded Xen kernel path |
691 |
- Fix grow-disk handling of invalid units |
692 |
- Update synopsis for ``gnt-cluster repair-disk-sizes`` |
693 |
- Accept both PUT and POST in noded (makes future upgrade to 2.6 easier) |
694 |
|
695 |
|
696 |
Version 2.5.0 |
697 |
------------- |
698 |
|
699 |
*(Released Thu, 12 Apr 2012)* |
700 |
|
701 |
Incompatible/important changes and bugfixes |
702 |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
703 |
|
704 |
- The default of the ``/2/instances/[instance_name]/rename`` RAPI |
705 |
resource's ``ip_check`` parameter changed from ``True`` to ``False`` |
706 |
to match the underlying LUXI interface. |
707 |
- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use |
708 |
body parameters, see :doc:`RAPI documentation <rapi>`. The server does |
709 |
not maintain backwards-compatibility as the underlying operation |
710 |
changed in an incompatible way. The RAPI client can talk to old |
711 |
servers, but it needs to be told so as the return value changed. |
712 |
- When creating file-based instances via RAPI, the ``file_driver`` |
713 |
parameter no longer defaults to ``loop`` and must be specified. |
714 |
- The deprecated ``bridge`` NIC parameter is no longer supported. Use |
715 |
``link`` instead. |
716 |
- Support for the undocumented and deprecated RAPI instance creation |
717 |
request format version 0 has been dropped. Use version 1, supported |
718 |
since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead. |
719 |
- Pyparsing 1.4.6 or above is required, see :doc:`installation |
720 |
documentation <install>`. |
721 |
- The "cluster-verify" hooks are now executed per group by the |
722 |
``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior |
723 |
if you just run ``gnt-cluster verify``, which generates one opcode per |
724 |
group. |
725 |
- The environment as passed to the OS scripts is cleared, and thus no |
726 |
environment variables defined in the node daemon's environment will be |
727 |
inherited by the scripts. |
728 |
- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been |
729 |
deprecated. |
730 |
- :doc:`New iallocator modes <design-multi-reloc>` have been added to |
731 |
support operations involving multiple node groups. |
732 |
- Offline nodes are ignored when failing over an instance. |
733 |
- Support for KVM version 1.0, which changed the version reporting format |
734 |
from 3 to 2 digits. |
735 |
- TCP/IP ports used by DRBD disks are returned to a pool upon instance |
736 |
removal. |
737 |
- ``Makefile`` is now compatible with Automake 1.11.2 |
738 |
- Includes all bugfixes made in the 2.4 series |
739 |
|
740 |
New features |
741 |
~~~~~~~~~~~~ |
742 |
|
743 |
- The ganeti-htools project has been merged into the ganeti-core source |
744 |
tree and will be built as part of Ganeti (see :doc:`install-quick`). |
745 |
- Implemented support for :doc:`shared storage <design-shared-storage>`. |
746 |
- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting |
747 |
GPT-style partition tables (requires `parted |
748 |
<http://www.gnu.org/s/parted/>`_). |
749 |
- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor. |
750 |
- Allowed adding tags on instance creation. |
751 |
- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`) |
752 |
- Allow instances to be started in a paused state, enabling the user to |
753 |
see the complete console output on boot using the console. |
754 |
- Added new hypervisor flag to control default reboot behaviour |
755 |
(``reboot_behavior``). |
756 |
- Added support for KVM keymaps (hypervisor parameter ``keymap``). |
757 |
- Improved out-of-band management support: |
758 |
|
759 |
- Added ``gnt-node health`` command reporting the health status of |
760 |
nodes. |
761 |
- Added ``gnt-node power`` command to manage power status of nodes. |
762 |
- Added command for emergency power-off (EPO), ``gnt-cluster epo``. |
763 |
|
764 |
- Instance migration can fall back to failover if instance is not |
765 |
running. |
766 |
- Filters can be used when listing nodes, instances, groups and locks; |
767 |
see :manpage:`ganeti(7)` manpage. |
768 |
- Added post-execution status as variables to :doc:`hooks <hooks>` |
769 |
environment. |
770 |
- Instance tags are exported/imported together with the instance. |
771 |
- When given an explicit job ID, ``gnt-job info`` will work for archived |
772 |
jobs. |
773 |
- Jobs can define dependencies on other jobs (not yet supported via |
774 |
RAPI or command line, but used by internal commands and usable via |
775 |
LUXI). |
776 |
|
777 |
- Lock monitor (``gnt-debug locks``) shows jobs waiting for |
778 |
dependencies. |
779 |
|
780 |
- Instance failover is now available as a RAPI resource |
781 |
(``/2/instances/[instance_name]/failover``). |
782 |
- ``gnt-instance info`` defaults to static information if primary node |
783 |
is offline. |
784 |
- Opcodes have a new ``comment`` attribute. |
785 |
- Added basic SPICE support to KVM hypervisor. |
786 |
- ``tools/ganeti-listrunner`` allows passing of arguments to executable. |
787 |
|
788 |
Node group improvements |
789 |
~~~~~~~~~~~~~~~~~~~~~~~ |
790 |
|
791 |
- ``gnt-cluster verify`` has been modified to check groups separately, |
792 |
thereby improving performance. |
793 |
- Node group support has been added to ``gnt-cluster verify-disks``, |
794 |
which now operates per node group. |
795 |
- Watcher has been changed to work better with node groups. |
796 |
|
797 |
- One process and state file per node group. |
798 |
- Slow watcher in one group doesn't block other group's watcher. |
799 |
|
800 |
- Added new command, ``gnt-group evacuate``, to move all instances in a |
801 |
node group to other groups. |
802 |
- Added ``gnt-instance change-group`` to move an instance to another |
803 |
node group. |
804 |
- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support |
805 |
per-group operations. |
806 |
- Node groups can be tagged. |
807 |
- Some operations switch from an exclusive to a shared lock as soon as |
808 |
possible. |
809 |
- Instance's primary and secondary nodes' groups are now available as |
810 |
query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group`` |
811 |
and ``snodes.group.uuid``). |
812 |
|
813 |
Misc |
814 |
~~~~ |
815 |
|
816 |
- Numerous updates to documentation and manpages. |
817 |
|
818 |
- :doc:`RAPI <rapi>` documentation now has detailed parameter |
819 |
descriptions. |
820 |
- Some opcode/job results are now also documented, see :doc:`RAPI |
821 |
<rapi>`. |
822 |
|
823 |
- A lockset's internal lock is now also visible in lock monitor. |
824 |
- Log messages from job queue workers now contain information about the |
825 |
opcode they're processing. |
826 |
- ``gnt-instance console`` no longer requires the instance lock. |
827 |
- A short delay when waiting for job changes reduces the number of LUXI |
828 |
requests significantly. |
829 |
- DRBD metadata volumes are overwritten with zeros during disk creation. |
830 |
- Out-of-band commands no longer acquire the cluster lock in exclusive |
831 |
mode. |
832 |
- ``devel/upload`` now uses correct permissions for directories. |
833 |
|
834 |
|
835 |

936 |
|
937 |
Many bug-fixes and a few small features: |
938 |
|
939 |
- Fixed argument order in ``ReserveLV`` and ``ReserveMAC`` which caused |
940 |
issues when you tried to add an instance with two MAC addresses in one |
941 |
request |
942 |
- KVM: fixed per-instance stored UID value |
943 |
- KVM: configure bridged NICs at migration start |
944 |
- KVM: Fix a bug where instance will not start with never KVM versions |
945 |
(>= 0.14) |
946 |
- Added OS search path to ``gnt-cluster info`` |
947 |
- Fixed an issue with ``file_storage_dir`` where you were forced to |
948 |
provide an absolute path, but the documentation states it is a |
949 |
relative path, the documentation was right |
950 |
- Added a new parameter to instance stop/start called ``--no-remember`` |
951 |
that will make the state change to not be remembered |
952 |
- Implemented ``no_remember`` at RAPI level |
953 |
- Improved the documentation |
954 |
- Node evacuation: don't call IAllocator if node is already empty |
955 |
- Fixed bug in DRBD8 replace disks on current nodes |
956 |
- Fixed bug in recreate-disks for DRBD instances |
957 |
- Moved assertion checking locks in ``gnt-instance replace-disks`` |
958 |
causing it to abort with not owning the right locks for some situation |
959 |
- Job queue: Fixed potential race condition when cancelling queued jobs |
960 |
- Fixed off-by-one bug in job serial generation |
961 |

|
968 |
Version 2.4.2 |
969 |
------------- |
970 |
|
971 |
*(Released Thu, 12 May 2011)* |
972 |
|
973 |
Many bug-fixes and a few new small features: |
974 |
|
975 |
- Fixed a bug related to log opening failures |
976 |
- Fixed a bug in instance listing with orphan instances |
977 |
- Fixed a bug which prevented resetting the cluster-level node parameter |
978 |
``oob_program`` to the default |
979 |
- Many fixes related to the ``cluster-merge`` tool |
980 |
- Fixed a race condition in the lock monitor, which caused failures |
981 |
during (at least) creation of many instances in parallel |
982 |
- Improved output for gnt-job info |
983 |
- Removed the quiet flag on some ssh calls which prevented debugging |
984 |
failures |
985 |
- Improved the N+1 failure messages in cluster verify by actually |
986 |
showing the memory values (needed and available) |
987 |
- Increased lock attempt timeouts so that when executing long operations |
988 |
(e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire' |
989 |
too early and thus prevent the use of the 'fair' mechanism |
990 |
- Changed instance query data (``gnt-instance info``) to not acquire |
991 |
locks unless needed, thus allowing its use on locked instance if only |
992 |
static information is asked for |
993 |
- Improved behaviour with filesystems that do not support rename on an |
994 |
opened file |
995 |
- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which |
996 |
kept locks on all nodes during the wipe, which is unneeded |
997 |
- Fixed ``gnt-watcher`` handling of errors during hooks execution |
998 |
- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than |
999 |
10GiB) which caused the wipe to fail right at the end in some cases |
1000 |
- Fixed master IP activation when doing master failover with no-voting |
1001 |
- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of |
1002 |
the master node itself |
1003 |
- Fixed potential data-loss in under disk full conditions, where Ganeti |
1004 |
wouldn't check correctly the return code and would consider |
1005 |
partially-written files 'correct' |
1006 |
- Fixed bug related to multiple VGs and DRBD disk replacing |
1007 |
- Added new disk parameter ``metavg`` that allows placement of the meta |
1008 |
device for DRBD in a different volume group |
1009 |
- Fixed error handling in the node daemon when the system libc doesn't |
1010 |
have major number 6 (i.e. if ``libc.so.6`` is not the actual libc) |
1011 |
- Fixed lock release during replace-disks, which kept cluster-wide locks |
1012 |
when doing disk replaces with an iallocator script |
1013 |
- Added check for missing bridges in cluster verify |
1014 |
- Handle EPIPE errors while writing to the terminal better, so that |
1015 |
piping the output to e.g. ``less`` doesn't cause a backtrace |
1016 |
- Fixed rare case where a ^C during Luxi calls could have been |
1017 |
interpreted as server errors, instead of simply terminating |
1018 |
- Fixed a race condition in LUGroupAssignNodes (``gnt-group |
1019 |
assign-nodes``) |
1020 |
- Added a few more parameters to the KVM hypervisor, allowing a second |
1021 |
CDROM, custom disk type for CDROMs and a floppy image |
1022 |
- Removed redundant message in instance rename when the name is given |
1023 |
already as a FQDN |
1024 |
- Added option to ``gnt-instance recreate-disks`` to allow creating the |
1025 |
disks on new nodes, allowing recreation when the original instance |
1026 |
nodes are completely gone |
1027 |
- Added option when converting disk templates to DRBD to skip waiting |
1028 |
for the resync, in order to make the instance available sooner |
1029 |
- Added two new variables to the OS scripts environment (containing the |
1030 |
instance's nodes) |
1031 |
- Made the root_path and optional parameter for the xen-pvm hypervisor, |
1032 |
to allow use of ``pvgrub`` as bootloader |
1033 |
- Changed the instance memory modifications to only check out-of-memory |
1034 |
conditions on memory increases, and turned the secondary node warnings |
1035 |
into errors (they can still be overridden via ``--force``) |
1036 |
- Fixed the handling of a corner case when the Python installation gets |
1037 |
corrupted (e.g. a bad disk) while ganeti-noded is running and we try |
1038 |
to execute a command that doesn't exist |
1039 |
- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary |
1040 |
node of the instance returned failures during instance shutdown; this |
1041 |
adds the option ``--ignore-consistency`` to gnt-instance move |
1042 |
|
1043 |
And as usual, various improvements to the error messages, documentation |
1044 |
and man pages. |
1045 |
|
1046 |
|
1047 |
Version 2.4.1 |
1048 |
------------- |
1049 |
|
1050 |
*(Released Wed, 09 Mar 2011)* |
1051 |
|
1052 |
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote |
1053 |
the RAPI users file if run twice (even with ``--dry-run``). |
1054 |
|
1055 |
The release fixes that bug (nothing else changed). |
1056 |
|
1057 |
|
1058 |
Version 2.4.0 |
1059 |
------------- |
1060 |
|
1061 |
*(Released Mon, 07 Mar 2011)* |
1062 |
|
1063 |
Final 2.4.0 release. Just a few small fixes: |
1064 |
|
1065 |
- Fixed RAPI node evacuate |
1066 |
- Fixed the kvm-ifup script |
1067 |
- Fixed internal error handling for special job cases |
1068 |
- Updated man page to specify the escaping feature for options |
1069 |
|
1070 |
|
1071 |
Version 2.4.0 rc3 |
1072 |
----------------- |
1073 |
|
1074 |
*(Released Mon, 28 Feb 2011)* |
1075 |
|
1076 |
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible |
1077 |
that this feature wiped the disks of the wrong instance, leading to loss |
1078 |
of data. |
1079 |
|
1080 |
Other changes: |
1081 |
|
1082 |
- Fixed title of query field containing instance name |
1083 |
- Expanded the glossary in the documentation |
1084 |
- Fixed one unittest (internal issue) |
1085 |
|
1086 |
|
1087 |
Version 2.4.0 rc2 |
1088 |
----------------- |
1089 |
|
1090 |
*(Released Mon, 21 Feb 2011)* |
1091 |
|
1092 |
A number of bug fixes plus just a couple functionality changes. |
1093 |
|
1094 |
On the user-visible side, the ``gnt-* list`` command output has changed |
1095 |
with respect to "special" field states. The current rc1 style of display |
1096 |
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in |
1097 |
the default output mode special fields states are displayed as follows: |
1098 |
|
1099 |
- Offline resource: ``*`` |
1100 |
- Unavailable/not applicable: ``-`` |
1101 |
- Data missing (RPC failure): ``?`` |
1102 |
- Unknown field: ``??`` |
1103 |
|
1104 |
Another user-visible change is the addition of ``--force-join`` to |
1105 |
``gnt-node add``. |
1106 |
|
1107 |
As for bug fixes: |
1108 |
|
1109 |
- ``tools/cluster-merge`` has seen many fixes and is now enabled again |
1110 |
- Fixed regression in RAPI/instance reinstall where all parameters were |
1111 |
required (instead of optional) |
1112 |
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2 |
1113 |
- Fixed iallocator usage (offline nodes were not considered offline) |
1114 |
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes |
1115 |
- Fixed hypervisor and OS parameter validation with respect to |
1116 |
non-vm_capable nodes |
1117 |
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly |
1118 |
cosmetic) |
1119 |
- Fixed ``tools/listrunner`` with respect to agent-based usage |
1120 |
|
1121 |
|
1122 |
Version 2.4.0 rc1 |
1123 |
----------------- |
1124 |
|
1125 |
*(Released Fri, 4 Feb 2011)* |
1126 |
|
1127 |
Many changes and fixes since the beta1 release. While there were some |
1128 |
internal changes, the code has been mostly stabilised for the RC |
1129 |
release. |
1130 |
|
1131 |
Note: the dumb allocator was removed in this release, as it was not kept |
1132 |
up-to-date with the IAllocator protocol changes. It is recommended to |
1133 |
use the ``hail`` command from the ganeti-htools package. |
1134 |
|
1135 |
Note: the 2.4 and up versions of Ganeti are not compatible with the |
1136 |
0.2.x branch of ganeti-htools. You need to upgrade to |
1137 |
ganeti-htools-0.3.0 (or later). |
1138 |
|
1139 |
Regressions fixed from 2.3 |
1140 |
~~~~~~~~~~~~~~~~~~~~~~~~~~ |
1141 |
|
1142 |
- Fixed the ``gnt-cluster verify-disks`` command |
1143 |
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to |
1144 |
serially on nodes) |
1145 |
- Fixed disk adoption breakage |
1146 |
- Fixed wrong headers in instance listing for field aliases |
1147 |
|
1148 |
Other bugs fixed |
1149 |
~~~~~~~~~~~~~~~~ |
1150 |
|
1151 |
- Fixed corner case in KVM handling of NICs |
1152 |
- Fixed many cases of wrong handling of non-vm_capable nodes |
1153 |
- Fixed a bug where a missing instance symlink was not possible to |
1154 |
recreate with any ``gnt-*`` command (now ``gnt-instance |
1155 |
activate-disks`` does it) |
1156 |
- Fixed the volume group name as reported by ``gnt-cluster |
1157 |
verify-disks`` |
1158 |
- Increased timeouts for the import-export code, hopefully leading to |
1159 |
fewer aborts due network or instance timeouts |
1160 |
- Fixed bug in ``gnt-node list-storage`` |
1161 |
- Fixed bug where not all daemons were started on cluster |
1162 |
initialisation, but only at the first watcher run |
1163 |
- Fixed many bugs in the OOB implementation |
1164 |
- Fixed watcher behaviour in presence of instances with offline |
1165 |
secondaries |
1166 |
- Fixed instance list output for instances running on the wrong node |
1167 |
- a few fixes to the cluster-merge tool, but it still cannot merge |
1168 |
multi-node groups (currently it is not recommended to use this tool) |
1169 |
|
1170 |
|
1171 |
Improvements |
1172 |
~~~~~~~~~~~~ |
1173 |
|
1174 |
- Improved network configuration for the KVM hypervisor |
1175 |
- Added e1000 as a supported NIC for Xen-HVM |
1176 |
- Improved the lvmstrap tool to also be able to use partitions, as |
1177 |
opposed to full disks |
1178 |
- Improved speed of disk wiping (the cluster parameter |
1179 |
``prealloc_wipe_disks``, so that it has a low impact on the total time |
1180 |
of instance creations |
1181 |
- Added documentation for the OS parameters |
1182 |
- Changed ``gnt-instance deactivate-disks`` so that it can work if the |
1183 |
hypervisor is not responding |
1184 |
- Added display of blacklisted and hidden OS information in |
1185 |
``gnt-cluster info`` |
1186 |
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend, |
1187 |
NIC and node parameters, which might create problems with currently |
1188 |
invalid (but undetected) configuration files, but prevents validation |
1189 |
failures when unrelated parameters are modified |
1190 |
- Changed cluster initialisation to wait for the master daemon to become |
1191 |
available |
1192 |
- Expanded the RAPI interface: |
1193 |
|
1194 |
- Added config redistribution resource |
1195 |
- Added activation/deactivation of instance disks |
1196 |
- Added export of console information |
1197 |
|
1198 |
- Implemented log file reopening on SIGHUP, which allows using |
1199 |
logrotate(8) for the Ganeti log files |
1200 |
- Added a basic OOB helper script as an example |
1201 |
|
1202 |
|
1203 |
Version 2.4.0 beta1 |
1204 |
------------------- |
1205 |
|
1206 |
*(Released Fri, 14 Jan 2011)* |
1207 |
|
1208 |
User-visible |
1209 |
~~~~~~~~~~~~ |
1210 |
|
1211 |
- Fixed timezone issues when formatting timestamps |
1212 |
- Added support for node groups, available via ``gnt-group`` and other |
1213 |
commands |
1214 |
- Added out-of-band framework and management, see :doc:`design |
1215 |
document <design-oob>` |
1216 |
- Removed support for roman numbers from ``gnt-node list`` and |
1217 |
``gnt-instance list``. |
1218 |
- Allowed modification of master network interface via ``gnt-cluster |
1219 |
modify --master-netdev`` |
1220 |
- Accept offline secondaries while shutting down instance disks |
1221 |
- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors |
1222 |
- Added support for multiple LVM volume groups |
1223 |
- Avoid sorting nodes for ``gnt-node list`` if specific nodes are |
1224 |
requested |
1225 |
- Added commands to list available fields: |
1226 |
|
1227 |
- ``gnt-node list-fields`` |
1228 |
- ``gnt-group list-fields`` |
1229 |
- ``gnt-instance list-fields`` |
1230 |
|
1231 |
- Updated documentation and man pages |
1232 |
|
1233 |
Integration |
1234 |
~~~~~~~~~~~ |
1235 |
|
1236 |
- Moved ``rapi_users`` file into separate directory, now named |
1237 |
``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a |
1238 |
symlink |
1239 |
- Added new tool for running commands on many machines, |
1240 |
``tools/ganeti-listrunner`` |
1241 |
- Implemented more verbose result in ``OpInstanceConsole`` opcode, also |
1242 |
improving the ``gnt-instance console`` output |
1243 |
- Allowed customisation of disk index separator at ``configure`` time |
1244 |
- Export node group allocation policy to :doc:`iallocator <iallocator>` |
1245 |
- Added support for non-partitioned md disks in ``lvmstrap`` |
1246 |
- Added script to gracefully power off KVM instances |
1247 |
- Split ``utils`` module into smaller parts |
1248 |
- Changed query operations to return more detailed information, e.g. |
1249 |
whether an information is unavailable due to an offline node. To use |
1250 |
this new functionality, the LUXI call ``Query`` must be used. Field |
1251 |
information is now stored by the master daemon and can be retrieved |
1252 |
using ``QueryFields``. Instances, nodes and groups can also be queried |
1253 |
using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet |
1254 |
exposed via RAPI). The following commands make use of this |
1255 |
infrastructure change: |
1256 |
|
1257 |
- ``gnt-group list`` |
1258 |
- ``gnt-group list-fields`` |
1259 |
- ``gnt-node list`` |
1260 |
- ``gnt-node list-fields`` |
1261 |
- ``gnt-instance list`` |
1262 |
- ``gnt-instance list-fields`` |
1263 |
- ``gnt-debug locks`` |
1264 |
|
1265 |
Remote API |
1266 |
~~~~~~~~~~ |
1267 |
|
1268 |
- New RAPI resources (see :doc:`rapi`): |
1269 |
|
1270 |
- ``/2/modify`` |
1271 |
- ``/2/groups`` |
1272 |
- ``/2/groups/[group_name]`` |
1273 |
- ``/2/groups/[group_name]/assign-nodes`` |
1274 |
- ``/2/groups/[group_name]/modify`` |
1275 |
- ``/2/groups/[group_name]/rename`` |
1276 |
- ``/2/instances/[instance_name]/disk/[disk_index]/grow`` |
1277 |
|
1278 |
- RAPI changes: |
1279 |
|
1280 |
- Implemented ``no_install`` for instance creation |
1281 |
- Implemented OS parameters for instance reinstallation, allowing |
1282 |
use of special settings on reinstallation (e.g. for preserving data) |
1283 |

1475 |
locks is expected for a later 2.2.x release |
1476 |

1477 |
- Support ``ssh-agent`` again when adding nodes |
1478 |
- Many additional bugfixes |

|
1480 |
|
1481 |
Version 2.2.0 rc0 |
1482 |
----------------- |
1483 |
|
1484 |
*(Released Fri, 30 Jul 2010)* |
1485 |
|
1486 |
Important change: the internal RPC mechanism between Ganeti nodes has |
1487 |
changed from using a home-grown http library (based on the Python base |
1488 |
libraries) to use the PycURL library. This requires that PycURL is |
1489 |
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked |
1490 |
against GnuTLS by default. cURL's support for GnuTLS had known issues |
1491 |
before cURL 7.21.0 and we recommend using the latest cURL release or |
1492 |
linking against OpenSSL. Most other distributions already link PycURL |
1493 |
and cURL against OpenSSL. The command:: |
1494 |
|
1495 |
python -c 'import pycurl; print pycurl.version' |
1496 |
|
1497 |
can be used to determine the libraries PycURL and cURL are linked |
1498 |
against. |
1499 |
|
1500 |
Other significant changes: |
1501 |
|
1502 |
- Rewrote much of the internals of the job queue, in order to achieve |
1503 |
better parallelism; this decouples job query operations from the job |
1504 |
processing, and it should allow much nicer behaviour of the master |
1505 |
daemon under load, and it also has uncovered some long-standing bugs |
1506 |
related to the job serialisation (now fixed) |
1507 |
- Added a default iallocator setting to the cluster parameters, |
1508 |
eliminating the need to always pass nodes or an iallocator for |
1509 |
operations that require selection of new node(s) |
1510 |
- Added experimental support for the LXC virtualization method |
1511 |
- Added support for OS parameters, which allows the installation of |
1512 |
instances to pass parameter to OS scripts in order to customise the |
1513 |
instance |
1514 |
- Added a hypervisor parameter controlling the migration type (live or |
1515 |
non-live), since hypervisors have various levels of reliability; this |
1516 |
has renamed the 'live' parameter to 'mode' |
1517 |
- Added a cluster parameter ``reserved_lvs`` that denotes reserved |
1518 |
logical volumes, meaning that cluster verify will ignore them and not |
1519 |
flag their presence as errors |
1520 |
- The watcher will now reset the error count for failed instances after |
1521 |
8 hours, thus allowing self-healing if the problem that caused the |
1522 |
instances to be down/fail to start has cleared in the meantime |
1523 |
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti |
1524 |
check for, and warn, if the drbd module parameter ``usermode_helper`` |
1525 |
is not consistent with the cluster-wide setting; this is needed to |
1526 |
make diagnose easier of failed drbd creations |
1527 |
- Started adding base IPv6 support, but this is not yet |
1528 |
enabled/available for use |
1529 |
- Rename operations (cluster, instance) will now return the new name, |
1530 |
which is especially useful if a short name was passed in |
1531 |
- Added support for instance migration in RAPI |
1532 |
- Added a tool to pre-configure nodes for the SSH setup, before joining |
1533 |
them to the cluster; this will allow in the future a simplified model |
1534 |
for node joining (but not yet fully enabled in 2.2); this needs the |
1535 |
paramiko python library |
1536 |
- Fixed handling of name-resolving errors |
1537 |
- Fixed consistency of job results on the error path |
1538 |
- Fixed master-failover race condition when executed multiple times in |
1539 |
sequence |
1540 |
- Fixed many bugs related to the job queue (mostly introduced during the |
1541 |
2.2 development cycle, so not all are impacting 2.1) |
1542 |
- Fixed instance migration with missing disk symlinks |
1543 |
- Fixed handling of unknown jobs in ``gnt-job archive`` |
1544 |
- And many other small fixes/improvements |
1545 |
|
1546 |
Internal changes: |
1547 |
|
1548 |
- Enhanced both the unittest and the QA coverage |
1549 |
- Switched the opcode validation to a generic model, and extended the |
1550 |
validation to all opcode parameters |
1551 |
- Changed more parts of the code that write shell scripts to use the |
1552 |
same class for this |
1553 |
- Switched the master daemon to use the asyncore library for the Luxi |
1554 |
server endpoint |
1555 |
|
1556 |
|
1557 |
Version 2.2.0 beta0 |
1558 |
------------------- |
1559 |
|
1560 |
*(Released Thu, 17 Jun 2010)* |
1561 |
|
1562 |
- Added tool (``move-instance``) and infrastructure to move instances |
1563 |
between separate clusters (see :doc:`separate documentation |
1564 |
<move-instance>` and :doc:`design document <design-2.2>`) |
1565 |
- Added per-request RPC timeout |
1566 |
- RAPI now requires a Content-Type header for requests with a body (e.g. |
1567 |
``PUT`` or ``POST``) which must be set to ``application/json`` (see |
1568 |
:rfc:`2616` (HTTP/1.1), section 7.2.1) |
1569 |
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not |
1570 |
reachable |
1571 |
- Implemented initial support for running Ganeti daemons as separate |
1572 |
users, see configure-time flags ``--with-user-prefix`` and |
1573 |
``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this |
1574 |
time) |
1575 |
- Instances can be removed after export (``gnt-backup export |
1576 |
--remove-instance``) |
1577 |
- Self-signed certificates generated by Ganeti now use a 2048 bit RSA |
1578 |
key (instead of 1024 bit) |
1579 |
- Added new cluster configuration file for cluster domain secret |
1580 |
- Import/export now use SSL instead of SSH |
1581 |
- Added support for showing estimated time when exporting an instance, |
1582 |
see the ``ganeti-os-interface(7)`` manpage and look for |
1583 |
``EXP_SIZE_FD`` |
1584 |
|
1585 |
|
1586 |

1600 |
Version 2.1.7 |
1601 |
------------- |
1602 |
|
1603 |
*(Released Tue, 24 Aug 2010)* |
1604 |
|
1605 |
Bugfixes only: |
1606 |
- Don't ignore secondary node silently on non-mirrored disk templates |
1607 |
(issue 113) |
1608 |
- Fix --master-netdev arg name in gnt-cluster(8) (issue 114) |

1617 |
Version 2.1.6 |
1618 |
------------- |
1619 |
|
1620 |
*(Released Fri, 16 Jul 2010)* |
1621 |
|
1622 |
Bugfixes only: |
1623 |
- Add an option to only select some reboot types during qa/burnin. |
1624 |
(on some hypervisors consequent reboots are not supported) |
1625 |
- Fix infrequent race condition in master failover. Sometimes the old |
1626 |
master ip address would be still detected as up for a short time |
1627 |
after it was removed, causing failover to fail. |
1628 |
- Decrease mlockall warnings when the ctypes module is missing. On |
1629 |
Python 2.4 we support running even if no ctypes module is installed, |
1630 |
but we were too verbose about this issue. |
1631 |
- Fix building on old distributions, on which man doesn't have a |
1632 |
--warnings option. |
1633 |
- Fix RAPI not to ignore the MAC address on instance creation |
1634 |
- Implement the old instance creation format in the RAPI client. |

A small bugfix release: |
1643 |
- Fix disk adoption: broken by strict --disk option checking in 2.1.4 |
1644 |
- Fix batch-create: broken in the whole 2.1 series due to a lookup on |
1645 |
a non-existing option |
1646 |
- Fix instance create: the --force-variant option was ignored |
1647 |
- Improve pylint 0.21 compatibility and warnings with Python 2.6 |
1648 |
- Fix modify node storage with non-FQDN arguments |
1649 |

1663 |
versions which had fewer hypervisor parameters |
1664 |
- Fix gnt-instance grow-disk on down instances |
1665 |
- Fix an error-reporting bug during instance migration |
1666 |

1667 |
silently ignoring broken ones |
1668 |
- Fix an RPC error reporting bug affecting, for example, RAPI client |
1669 |
users |
1670 |
- Fix bug triggered by different API version os-es on different nodes |
1671 |
- Fix a bug in instance startup with custom hvparams: OS level |
1672 |
parameters would fail to be applied. |
1673 |
- Fix the RAPI client under Python 2.6 (but more work is needed to |
1674 |
make it work completely well with OpenSSL) |
1675 |
- Fix handling of errors when resolving names from DNS |
1676 |
|

Version 2.1.3 |
1679 |
------------- |
1680 |
|
1681 |
*(Released Thu, 3 Jun 2010)* |
1682 |
|
1683 |
A medium sized development cycle. Some new features, and some |
1684 |
fixes/small improvements/cleanups. |
1685 |
|
1686 |
Significant features |
1687 |
~~~~~~~~~~~~~~~~~~~~ |
1688 |
|
1689 |
The node deamon now tries to mlock itself into memory, unless the |
1690 |
``--no-mlock`` flag is passed. It also doesn't fail if it can't write |
1691 |
its logs, and falls back to console logging. This allows emergency |
1692 |
features such as ``gnt-node powercycle`` to work even in the event of a |
1693 |
broken node disk (tested offlining the disk hosting the node's |
1694 |
filesystem and dropping its memory caches; don't try this at home) |
1695 |
|
1696 |
KVM: add vhost-net acceleration support. It can be tested with a new |
1697 |
enough version of the kernel and of qemu-kvm. |
1698 |
|
1699 |
KVM: Add instance chrooting feature. If you use privilege dropping for |
1700 |
your VMs you can also now force them to chroot to an empty directory, |
1701 |
before starting the emulated guest. |
1702 |
|
1703 |
KVM: Add maximum migration bandwith and maximum downtime tweaking |
1704 |
support (requires a new-enough version of qemu-kvm). |
1705 |
|
1706 |
Cluster verify will now warn if the master node doesn't have the master |
1707 |
ip configured on it. |
1708 |
|
1709 |
Add a new (incompatible) instance creation request format to RAPI which |
1710 |
supports all parameters (previously only a subset was supported, and it |
1711 |
wasn't possible to extend the old format to accomodate all the new |
1712 |
features. The old format is still supported, and a client can check for |
1713 |
this feature, before using it, by checking for its presence in the |
1714 |
``features`` RAPI resource. |
1715 |
|
1716 |
Now with ancient latin support. Try it passing the ``--roman`` option to |
1717 |
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list`` |
1718 |
(requires the python-roman module to be installed, in order to work). |
1719 |
|
1720 |
Other changes |
1721 |
~~~~~~~~~~~~~ |
1722 |
|
1723 |
As usual many internal code refactorings, documentation updates, and |
1724 |
such. Among others: |
1725 |
|
1726 |
- Lots of improvements and cleanups to the experimental Remote API |
1727 |
(RAPI) client library. |
1728 |
- A new unit test suite for the core daemon libraries. |
1729 |
- A fix to creating missing directories makes sure the umask is not |
1730 |
applied anymore. This enforces the same directory permissions |
1731 |
everywhere. |
1732 |
- Better handling terminating daemons with ctrl+c (used when running |
1733 |
them in debugging mode). |
1734 |
- Fix a race condition in live migrating a KVM instance, when stat() |
1735 |
on the old proc status file returned EINVAL, which is an unexpected |
1736 |
value. |
1737 |
- Fixed manpage checking with newer man and utf-8 charachters. But now |
1738 |
you need the en_US.UTF-8 locale enabled to build Ganeti from git. |

Version 2.1.2.1 |
1742 |
--------------- |
1743 |
|
1744 |
*(Released Fri, 7 May 2010)* |
1745 |
|
1746 |
Fix a bug which prevented untagged KVM instances from starting. |
1747 |

1749 |
Version 2.1.2 |
1750 |
------------- |
1751 |
|
1752 |
*(Released Fri, 7 May 2010)* |
1753 |
|
1754 |
Another release with a long development cycle, during which many |
1755 |
different features were added. |
1756 |
|
1757 |
Significant features |
1758 |
~~~~~~~~~~~~~~~~~~~~ |
1759 |
|
1760 |
The KVM hypervisor now can run the individual instances as non-root, to |
1761 |
reduce the impact of a VM being hijacked due to bugs in the |
1762 |
hypervisor. It is possible to run all instances as a single (non-root) |
1763 |
user, to manually specify a user for each instance, or to dynamically |
1764 |
allocate a user out of a cluster-wide pool to each instance, with the |
1765 |
guarantee that no two instances will run under the same user ID on any |
1766 |
given node. |
1767 |
|
1768 |
An experimental RAPI client library, that can be used standalone |
1769 |
(without the other Ganeti libraries), is provided in the source tree as |
1770 |
``lib/rapi/client.py``. Note this client might change its interface in |
1771 |
the future, as we iterate on its capabilities. |
1772 |
|
1773 |
A new command, ``gnt-cluster renew-crypto`` has been added to easily |
1774 |
replace the cluster's certificates and crypto keys. This might help in |
1775 |
case they have been compromised, or have simply expired. |
1776 |
|
1777 |
A new disk option for instance creation has been added that allows one |
1778 |
to "adopt" currently existing logical volumes, with data |
1779 |
preservation. This should allow easier migration to Ganeti from |
1780 |
unmanaged (or managed via other software) instances. |
1781 |
|
1782 |
Another disk improvement is the possibility to convert between redundant |
1783 |
(DRBD) and plain (LVM) disk configuration for an instance. This should |
1784 |
allow better scalability (starting with one node and growing the |
1785 |
cluster, or shrinking a two-node cluster to one node). |
1786 |
|
1787 |
A new feature that could help with automated node failovers has been |
1788 |
implemented: if a node sees itself as offline (by querying the master |
1789 |
candidates), it will try to shutdown (hard) all instances and any active |
1790 |
DRBD devices. This reduces the risk of duplicate instances if an |
1791 |
external script automatically failovers the instances on such nodes. To |
1792 |
enable this, the cluster parameter ``maintain_node_health`` should be |
1793 |
enabled; in the future this option (per the name) will enable other |
1794 |
automatic maintenance features. |
1795 |
|
1796 |
Instance export/import now will reuse the original instance |
1797 |
specifications for all parameters; that means exporting an instance, |
1798 |
deleting it and the importing it back should give an almost identical |
1799 |
instance. Note that the default import behaviour has changed from |
1800 |
before, where it created only one NIC; now it recreates the original |
1801 |
number of NICs. |
1802 |
|
1803 |
Cluster verify has added a few new checks: SSL certificates validity, |
1804 |
/etc/hosts consistency across the cluster, etc. |
1805 |
|
1806 |
Other changes |
1807 |
~~~~~~~~~~~~~ |
1808 |
|
1809 |
As usual, many internal changes were done, documentation fixes, |
1810 |
etc. Among others: |
1811 |
|
1812 |
- Fixed cluster initialization with disabled cluster storage (regression |
1813 |
introduced in 2.1.1) |
1814 |
- File-based storage supports growing the disks |
1815 |
- Fixed behaviour of node role changes |
1816 |
- Fixed cluster verify for some corner cases, plus a general rewrite of |
1817 |
cluster verify to allow future extension with more checks |
1818 |
- Fixed log spamming by watcher and node daemon (regression introduced |
1819 |
in 2.1.1) |
1820 |
- Fixed possible validation issues when changing the list of enabled |
1821 |
hypervisors |
1822 |
- Fixed cleanup of /etc/hosts during node removal |
1823 |
- Fixed RAPI response for invalid methods |
1824 |
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon |
1825 |
- Multiple small improvements to the KVM hypervisor (VNC usage, booting |
1826 |
from ide disks, etc.) |
1827 |
- Allow OS changes without re-installation (to record a changed OS |
1828 |
outside of Ganeti, or to allow OS renames) |
1829 |
- Allow instance creation without OS installation (useful for example if |
1830 |
the OS will be installed manually, or restored from a backup not in |
1831 |
Ganeti format) |
1832 |
- Implemented option to make cluster ``copyfile`` use the replication |
1833 |
network |
1834 |
- Added list of enabled hypervisors to ssconf (possibly useful for |
1835 |
external scripts) |
1836 |
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from |
1837 |
1.2 clusters |
1838 |
- A partial form of node re-IP is possible via node readd, which now |
1839 |
allows changed node primary IP |
1840 |
- Command line utilities now show an informational message if the job is |
1841 |
waiting for a lock |
1842 |
- The logs of the master daemon now show the PID/UID/GID of the |
1843 |
connected client |
1844 |
|
1845 |
|
1846 |
Version 2.1.1 |
1847 |
------------- |
1848 |
|
1849 |
*(Released Fri, 12 Mar 2010)* |
1850 |
|
1851 |
During the 2.1.0 long release candidate cycle, a lot of improvements and |
1852 |
changes have accumulated with were released later as 2.1.1. |
1853 |
|
1854 |
Major changes |
1855 |
~~~~~~~~~~~~~ |
1856 |
|
1857 |
The node evacuate command (``gnt-node evacuate``) was significantly |
1858 |
rewritten, and as such the IAllocator protocol was changed - a new |
1859 |
request type has been added. This unfortunate change during a stable |
1860 |
series is designed to improve performance of node evacuations; on |
1861 |
clusters with more than about five nodes and which are well-balanced, |
1862 |
evacuation should proceed in parallel for all instances of the node |
1863 |
being evacuated. As such, any existing IAllocator scripts need to be |
1864 |
updated, otherwise the above command will fail due to the unknown |
1865 |
request. The provided "dumb" allocator has not been updated; but the |
1866 |
ganeti-htools package supports the new protocol since version 0.2.4. |
1867 |
|
1868 |
Another important change is increased validation of node and instance |
1869 |
names. This might create problems in special cases, if invalid host |
1870 |
names are being used. |
1871 |
|
1872 |
Also, a new layer of hypervisor parameters has been added, that sits at |
1873 |
OS level between the cluster defaults and the instance ones. This allows |
1874 |
customisation of virtualization parameters depending on the installed |
1875 |
OS. For example instances with OS 'X' may have a different KVM kernel |
1876 |
(or any other parameter) than the cluster defaults. This is intended to |
1877 |
help managing a multiple OSes on the same cluster, without manual |
1878 |
modification of each instance's parameters. |
1879 |
|
1880 |
A tool for merging clusters, ``cluster-merge``, has been added in the |
1881 |
tools sub-directory. |
1882 |
|
1883 |
Bug fixes |
1884 |
~~~~~~~~~ |
1885 |
|
1886 |
- Improved the int/float conversions that should make the code more |
1887 |
robust in face of errors from the node daemons |
1888 |
- Fixed the remove node code in case of internal configuration errors |
1889 |
- Fixed the node daemon behaviour in face of inconsistent queue |
1890 |
directory (e.g. read-only file-system where we can't open the files |
1891 |
read-write, etc.) |
1892 |
- Fixed the behaviour of gnt-node modify for master candidate demotion; |
1893 |
now it either aborts cleanly or, if given the new "auto_promote" |
1894 |
parameter, will automatically promote other nodes as needed |
1895 |
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would |
1896 |
completely prevent Ganeti from working |
1897 |
- Fixed bug for instance export when not all disks were successfully |
1898 |
exported |
1899 |
- Fixed behaviour of node add when the new node is slow in starting up |
1900 |
the node daemon |
1901 |
- Fixed handling of signals in the LUXI client, which should improve |
1902 |
behaviour of command-line scripts |
1903 |
- Added checks for invalid node/instance names in the configuration (now |
1904 |
flagged during cluster verify) |
1905 |
- Fixed watcher behaviour for disk activation errors |
1906 |
- Fixed two potentially endless loops in http library, which led to the |
1907 |
RAPI daemon hanging and consuming 100% CPU in some cases |
1908 |
- Fixed bug in RAPI daemon related to hashed passwords |
1909 |
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM |
1910 |
instances |
1911 |
- Enhanced compatibility with non-Debian OSes, but not using absolute |
1912 |
path in some commands and allowing customisation of the ssh |
1913 |
configuration directory |
1914 |
- Fixed possible future issue with new Python versions by abiding to the |
1915 |
proper use of ``__slots__`` attribute on classes |
1916 |
- Added checks that should prevent directory traversal attacks |
1917 |
- Many documentation fixes based on feedback from users |
1918 |
|
1919 |
New features |
1920 |
~~~~~~~~~~~~ |
1921 |
|
1922 |
- Added an "early_release" more for instance replace disks and node |
1923 |
evacuate, where we release locks earlier and thus allow higher |
1924 |
parallelism within the cluster |
1925 |
- Added watcher hooks, intended to allow the watcher to restart other |
1926 |
daemons (e.g. from the ganeti-nbma project), but they can be used of |
1927 |
course for any other purpose |
1928 |
- Added a compile-time disable for DRBD barriers, to increase |
1929 |
performance if the administrator trusts the power supply or the |
1930 |
storage system to not lose writes |
1931 |
- Added the option of using syslog for logging instead of, or in |
1932 |
addition to, Ganeti's own log files |
1933 |
- Removed boot restriction for paravirtual NICs for KVM, recent versions |
1934 |
can indeed boot from a paravirtual NIC |
1935 |
- Added a generic debug level for many operations; while this is not |
1936 |
used widely yet, it allows one to pass the debug value all the way to |
1937 |
the OS scripts |
1938 |
- Enhanced the hooks environment for instance moves (failovers, |
1939 |
migrations) where the primary/secondary nodes changed during the |
1940 |
operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars |
1941 |
- Enhanced data validations for many user-supplied values; one important |
1942 |
item is the restrictions imposed on instance and node names, which |
1943 |
might reject some (invalid) host names |
1944 |
- Add a configure-time option to disable file-based storage, if it's not |
1945 |
needed; this allows greater security separation between the master |
1946 |
node and the other nodes from the point of view of the inter-node RPC |
1947 |
protocol |
1948 |
- Added user notification in interactive tools if job is waiting in the |
1949 |
job queue or trying to acquire locks |
1950 |
- Added log messages when a job is waiting for locks |
1951 |
- Added filtering by node tags in instance operations which admit |
1952 |
multiple instances (start, stop, reboot, reinstall) |
1953 |
- Added a new tool for cluster mergers, ``cluster-merge`` |
1954 |
- Parameters from command line which are of the form ``a=b,c=d`` can now |
1955 |
use backslash escapes to pass in values which contain commas, |
1956 |
e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value |
1957 |
``b,c`` |
1958 |
- For KVM, the instance name is the first parameter passed to KVM, so |
1959 |
that it's more visible in the process list |
1960 |
|
1961 |
|
1962 |
Version 2.1.0 |
1963 |
------------- |
1964 |
|
1965 |
*(Released Tue, 2 Mar 2010)* |
1966 |
|
1967 |
Ganeti 2.1 brings many improvements with it. Major changes: |
1968 |
|
1969 |
- Added infrastructure to ease automated disk repairs |
1970 |
- Added new daemon to export configuration data in a cheaper way than |
1971 |
using the remote API |
1972 |
- Instance NICs can now be routed instead of being associated with a |
1973 |
networking bridge |
1974 |
- Improved job locking logic to reduce impact of jobs acquiring multiple |
1975 |
locks waiting for other long-running jobs |
1976 |
|
1977 |
In-depth implementation details can be found in the Ganeti 2.1 design |
1978 |

2114 |
- Added script to clean archived jobs after 21 days; this will reduce |
2115 |
the size of the queue directory |
2116 |
- Added some extra checks in disk size tracking |
2117 |
- Added an example ethers hook script |
2118 |
- Added a cluster parameter that prevents Ganeti from modifying of |
2119 |
/etc/hosts |
2120 |
- Added more node information to RAPI responses |
2121 |
- Added a ``gnt-job watch`` command that allows following the ouput of a |
2122 |
job |
2123 |
- Added a bind-address option to ganeti-rapi |
2124 |
- Added more checks to the configuration verify |
2125 |
- Enhanced the burnin script such that some operations can be retried |
2126 |
automatically |
2127 |
- Converted instance reinstall to multi-instance model |
2128 |
|
2129 |

Version 2.0.3 |
2131 |
------------- |
2132 |
|
2133 |
*(Released Fri, 7 Aug 2009)* |
2134 |
|
2135 |
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
2136 |
to allow using the pre-2.0.2 behaviour in activation, if any existing |
2137 |
instances have mismatched disk sizes in the configuration |
2138 |
- Added ``gnt-cluster repair-disk-sizes`` command to check and update |
2139 |
any configuration mismatches for disk sizes |
2140 |
- Added ``gnt-master cluste-failover --no-voting`` to allow master |
2141 |
failover to work on two-node clusters |
2142 |
- Fixed the ``--net`` option of ``gnt-backup import``, which was |
2143 |
unusable |
2144 |
- Fixed detection of OS script errors in ``gnt-backup export`` |
2145 |
- Fixed exit code of ``gnt-backup export`` |
2146 |
|
2147 |
|
2148 |
Version 2.0.2 |
2149 |
------------- |
2150 |
|
2151 |
*(Released Fri, 17 Jul 2009)* |
2152 |
|
2153 |
- Added experimental support for stripped logical volumes; this should |
2154 |
enhance performance but comes with a higher complexity in the block |
2155 |
device handling; stripping is only enabled when passing |
2156 |
``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
2157 |
affected even in the non-stripped mode |
2158 |
- Improved resiliency against transient failures at the end of DRBD |
2159 |
resyncs, and in general of DRBD resync checks |
2160 |
- Fixed a couple of issues with exports and snapshot errors |
2161 |
- Fixed a couple of issues in instance listing |
2162 |
- Added display of the disk size in ``gnt-instance info`` |
2163 |
- Fixed checking for valid OSes in instance creation |
2164 |
- Fixed handling of the "vcpus" parameter in instance listing and in |
2165 |
general of invalid parameters |
2166 |
- Fixed http server library, and thus RAPI, to handle invalid |
2167 |
username/password combinations correctly; this means that now they |
2168 |
report unauthorized for queries too, not only for modifications, |
2169 |
allowing earlier detect of configuration problems |
2170 |
- Added a new "role" node list field, equivalent to the master/master |
2171 |
candidate/drained/offline flags combinations |
2172 |
- Fixed cluster modify and changes of candidate pool size |
2173 |
- Fixed cluster verify error messages for wrong files on regular nodes |
2174 |
- Fixed a couple of issues with node demotion from master candidate role |
2175 |
- Fixed node readd issues |
2176 |
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
2177 |
- Added a new ``--no-voting`` option for masterfailover to fix failover |
2178 |
on two-nodes clusters when the former master node is unreachable |
2179 |
- Added instance reinstall over RAPI |
2180 |
|
2181 |
|
2182 |
Version 2.0.1 |
2183 |
------------- |
2184 |
|
2185 |
*(Released Tue, 16 Jun 2009)* |
2186 |
|
2187 |
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
2188 |
allow re-adding the start in single-user option (regression from 1.2) |
2189 |
- the watcher writes the instance status to a file, to allow monitoring |
2190 |
to report the instance status (from the master) based on cached |
2191 |
results of the watcher's queries; while this can get stale if the |
2192 |
watcher is being locked due to other work on the cluster, this is |
2193 |
still an improvement |
2194 |
- the watcher now also restarts the node daemon and the rapi daemon if |
2195 |
they died |
2196 |
- fixed the watcher to handle full and drained queue cases |
2197 |
- hooks export more instance data in the environment, which helps if |
2198 |
hook scripts need to take action based on the instance's properties |
2199 |
(no longer need to query back into ganeti) |
2200 |
- instance failovers when the instance is stopped do not check for free |
2201 |
RAM, so that failing over a stopped instance is possible in low memory |
2202 |
situations |
2203 |
- rapi uses queries for tags instead of jobs (for less job traffic), and |
2204 |
for cluster tags it won't talk to masterd at all but read them from |
2205 |
ssconf |
2206 |
- a couple of error handling fixes in RAPI |
2207 |
- drbd handling: improved the error handling of inconsistent disks after |
2208 |
resync to reduce the frequency of "there are some degraded disks for |
2209 |
this instance" messages |
2210 |
- fixed a bug in live migration when DRBD doesn't want to reconnect (the |
2211 |
error handling path called a wrong function name) |
2212 |
|
2213 |
|
2214 |
Version 2.0.0 |
2215 |
------------- |
2216 |
|
2217 |
*(Released Wed, 27 May 2009)* |
2218 |
|
2219 |
- no changes from rc5 |
2220 |
|
2221 |
|
2222 |
Version 2.0 rc5 |
2223 |
--------------- |
2224 |
|
2225 |
*(Released Wed, 20 May 2009)* |
2226 |
|
2227 |
- fix a couple of bugs (validation, argument checks) |
2228 |
- fix ``gnt-cluster getmaster`` on non-master nodes (regression) |
2229 |
- some small improvements to RAPI and IAllocator |
2230 |
- make watcher automatically start the master daemon if down |
2231 |
|
2232 |
|
2233 |
Version 2.0 rc4 |
2234 |
--------------- |
2235 |
|
2236 |
*(Released Mon, 27 Apr 2009)* |
2237 |
|
2238 |
- change the OS list to not require locks; this helps with big clusters |
2239 |
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the |
2240 |
volume group is broken |
2241 |
- ``gnt-instance info``, without any arguments, doesn't run for all |
2242 |
instances anymore; either pass ``--all`` or pass the desired |
2243 |
instances; this helps against mistakes on big clusters where listing |
2244 |
the information for all instances takes a long time |
2245 |
- miscellaneous doc and man pages fixes |
2246 |
|
2247 |
|
2248 |
Version 2.0 rc3 |
2249 |
--------------- |
2250 |
|
2251 |
*(Released Wed, 8 Apr 2009)* |
2252 |
|
2253 |
- Change the internal locking model of some ``gnt-node`` commands, in |
2254 |
order to reduce contention (and blocking of master daemon) when |
2255 |
batching many creation/reinstall jobs |
2256 |
- Fixes to Xen soft reboot |
2257 |
- No longer build documentation at build time, instead distribute it in |
2258 |
the archive, in order to reduce the need for the whole docbook/rst |
2259 |
toolchains |
2260 |
|
2261 |
|
2262 |
Version 2.0 rc2 |
2263 |
--------------- |
2264 |
|
2265 |
*(Released Fri, 27 Mar 2009)* |
2266 |
|
2267 |
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0 |
2268 |
- Fix watcher startup sequence, improves the behaviour of busy clusters |
2269 |
- Some other fixes in ``gnt-cluster verify``, ``gnt-instance |
2270 |
replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC |
2271 |
bind address and other places |
2272 |
- Some documentation fixes and updates |
2273 |
|
2274 |
|
2275 |
Version 2.0 rc1 |
2276 |
--------------- |
2277 |
|
2278 |
*(Released Mon, 2 Mar 2009)* |
2279 |
|
2280 |
- More documentation updates, now all docs should be more-or-less |
2281 |
up-to-date |
2282 |
- A couple of small fixes (mixed hypervisor clusters, offline nodes, |
2283 |
etc.) |
2284 |
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM |
2285 |
and KVM) |
2286 |
- Fix an issue related to $libdir/run/ganeti and cluster creation |
2287 |
|
2288 |
|
2289 |
Version 2.0 beta2 |
2290 |
----------------- |
2291 |
|
2292 |
*(Released Thu, 19 Feb 2009)* |
2293 |
|
2294 |
- Xen PVM and KVM have switched the default value for the instance root |
2295 |
disk to the first partition on the first drive, instead of the whole |
2296 |
drive; this means that the OS installation scripts must be changed |
2297 |
accordingly |
2298 |
- Man pages have been updated |
2299 |
- RAPI has been switched by default to HTTPS, and the exported functions |
2300 |
should all work correctly |
2301 |
- RAPI v1 has been removed |
2302 |
- Many improvements to the KVM hypervisor |
2303 |
- Block device errors are now better reported |
2304 |
- Many other bugfixes and small improvements |
2305 |
|
2306 |
|
2307 |
Version 2.0 beta1 |
2308 |
----------------- |
2309 |
|
2310 |
*(Released Mon, 26 Jan 2009)* |
2311 |
|
2312 |
- Version 2 is a general rewrite of the code and therefore the |
2313 |
differences are too many to list, see the design document for 2.0 in |
2314 |
the ``doc/`` subdirectory for more details |
2315 |
- In this beta version there is not yet a migration path from 1.2 (there |
2316 |
will be one in the final 2.0 release) |
2317 |
- A few significant changes are: |
2318 |
|
2319 |
- all commands are executed by a daemon (``ganeti-masterd``) and the |
2320 |
various ``gnt-*`` commands are just front-ends to it |
2321 |
- all the commands are entered into, and executed from a job queue, |
2322 |
see the ``gnt-job(8)`` manpage |
2323 |
- the RAPI daemon supports read-write operations, secured by basic |
2324 |
HTTP authentication on top of HTTPS |
2325 |
- DRBD version 0.7 support has been removed, DRBD 8 is the only |
2326 |
supported version (when migrating from Ganeti 1.2 to 2.0, you need |
2327 |
to migrate to DRBD 8 first while still running Ganeti 1.2) |
2328 |
- DRBD devices are using statically allocated minor numbers, which |
2329 |
will be assigned to existing instances during the migration process |
2330 |
- there is support for both Xen PVM and Xen HVM instances running on |
2331 |
the same cluster |
2332 |
- KVM virtualization is supported too |
2333 |
- file-based storage has been implemented, which means that it is |
2334 |
possible to run the cluster without LVM and DRBD storage, for |
2335 |
example using a shared filesystem exported from shared storage (and |
2336 |
still have live migration) |
2337 |
|
2338 |
|
2339 |
Version 1.2.7 |
2340 |
------------- |
2341 |
|
2342 |
*(Released Tue, 13 Jan 2009)* |
2343 |
|
2344 |
- Change the default reboot type in ``gnt-instance reboot`` to "hard" |
2345 |
- Reuse the old instance mac address by default on instance import, if |
2346 |
the instance name is the same. |
2347 |
- Handle situations in which the node info rpc returns incomplete |
2348 |
results (issue 46) |
2349 |
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify`` |
2350 |
- Improved version of batcher: |
2351 |
|
2352 |
- state file support |
2353 |
- instance mac address support |
2354 |
- support for HVM clusters/instances |
2355 |
|
2356 |
- Add an option to show the number of cpu sockets and nodes in |
2357 |
``gnt-node list`` |
2358 |
- Support OSes that handle more than one version of the OS api (but do |
2359 |
not change the current API in any other way) |
2360 |
- Fix ``gnt-node migrate`` |
2361 |
- ``gnt-debug`` man page |
2362 |
- Fixes various more typos and small issues |
2363 |
- Increase disk resync maximum speed to 60MB/s (from 30MB/s) |
2364 |
|
2365 |
|
2366 |
Version 1.2.6 |
2367 |
------------- |
2368 |
|
2369 |
*(Released Wed, 24 Sep 2008)* |
2370 |
|
2371 |
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
2372 |
type of disk exported to fully virtualized instances. |
2373 |
- provide access to the serial console of HVM instances |
2374 |
- instance auto_balance flag, set by default. If turned off it will |
2375 |
avoid warnings on cluster verify if there is not enough memory to fail |
2376 |
over an instance. in the future it will prevent automatically failing |
2377 |
it over when we will support that. |
2378 |
- batcher tool for instance creation, see ``tools/README.batcher`` |
2379 |
- ``gnt-instance reinstall --select-os`` to interactively select a new |
2380 |
operating system when reinstalling an instance. |
2381 |
- when changing the memory amount on instance modify a check has been |
2382 |
added that the instance will be able to start. also warnings are |
2383 |
emitted if the instance will not be able to fail over, if auto_balance |
2384 |
is true. |
2385 |
- documentation fixes |
2386 |
- sync fields between ``gnt-instance list/modify/add/import`` |
2387 |
- fix a race condition in drbd when the sync speed was set after giving |
2388 |
the device a remote peer. |
2389 |
|
2390 |
|
2391 |
Version 1.2.5 |
2392 |
------------- |
2393 |
|
2394 |
*(Released Tue, 22 Jul 2008)* |
2395 |
|
2396 |
- note: the allowed size and number of tags per object were reduced |
2397 |
- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups |
2398 |
- fixed twisted 8.x compatibility |
2399 |
- fixed ``gnt-instance replace-disks`` with iallocator |
2400 |
- add TCP keepalives on twisted connections to detect restarted nodes |
2401 |
- disk increase support, see ``gnt-instance grow-disk`` |
2402 |
- implement bulk node/instance query for RAPI |
2403 |
- add tags in node/instance listing (optional) |
2404 |
- experimental migration (and live migration) support, read the man page |
2405 |
for ``gnt-instance migrate`` |
2406 |
- the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
2407 |
has some small improvements in handling its state file |
2408 |
|
2409 |
|
2410 |
Version 1.2.4 |
2411 |
------------- |
2412 |
|
2413 |
*(Released Fri, 13 Jun 2008)* |
2414 |
|
2415 |
- Experimental readonly, REST-based remote API implementation; |
2416 |
automatically started on master node, TCP port 5080, if enabled by |
2417 |
``--enable-rapi`` parameter to configure script. |
2418 |
- Instance allocator support. Add and import instance accept a |
2419 |
``--iallocator`` parameter, and call that instance allocator to decide |
2420 |
which node to use for the instance. The iallocator document describes |
2421 |
what's expected from an allocator script. |
2422 |
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
2423 |
``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
2424 |
node is lost there is still enough memory to fail over the instances |
2425 |
that reside on it. |
2426 |
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
2427 |
``gnt-cluster verify``, to check for site-specific compliance. All the |
2428 |
hooks will run, and their output, if any, will be displayed. Any |
2429 |
failing hook will make the verification return an error value. |
2430 |
- ``gnt-cluster verify`` now checks that its peers are reachable on the |
2431 |
primary and secondary interfaces |
2432 |
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
2433 |
that is still declared as part of the cluster and has failed. |
2434 |
- ``gnt-* list`` commands now accept a new ``-o +field`` way of |
2435 |
specifying output fields, that just adds the chosen fields to the |
2436 |
default ones. |
2437 |
- ``gnt-backup`` now has a new ``remove`` command to delete an existing |
2438 |
export from the filesystem. |
2439 |
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
2440 |
have been added. Using them you can enable/disable acpi and pae |
2441 |
support, and specify a path for a cd image to be exported to the |
2442 |
instance. These parameters as the name suggest only work on HVM |
2443 |
clusters. |
2444 |
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
2445 |
PAE support will be set to the previously hardcoded values, but the |
2446 |
(previously hardcoded) path to the CDROM ISO image will be unset and |
2447 |
if required, needs to be set manually with ``gnt-instance modify`` |
2448 |
after the upgrade. |
2449 |
- The address to which an instance's VNC console is bound is now |
2450 |
selectable per-instance, rather than being cluster wide. Of course |
2451 |
this only applies to instances controlled via VNC, so currently just |
2452 |
applies to HVM clusters. |
2453 |
|
2454 |
|
2455 |
Version 1.2.3 |
2456 |
------------- |
2457 |
|
2458 |
*(Released Mon, 18 Feb 2008)* |
2459 |
|
2460 |
- more tweaks to the disk activation code (especially helpful for DRBD) |
2461 |
- change the default ``gnt-instance list`` output format, now there is |
2462 |
one combined status field (see the manpage for the exact values this |
2463 |
field will have) |
2464 |
- some more fixes for the mac export to hooks change |
2465 |
- make Ganeti not break with DRBD 8.2.x (which changed the version |
2466 |
format in ``/proc/drbd``) (issue 24) |
2467 |
- add an upgrade tool from "remote_raid1" disk template to "drbd" disk |
2468 |
template, allowing migration from DRBD0.7+MD to DRBD8 |
2469 |
|
2470 |
|
2471 |
Version 1.2.2 |
2472 |
------------- |

|
2476 |
- fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM |
2477 |
support (issue 23) |
2478 |
- add command aliases infrastructure and a few aliases |
2479 |
- allow listing of VCPUs in the ``gnt-instance list`` and improve the |
2480 |
man pages and the ``--help`` option of ``gnt-node |
2481 |
list``/``gnt-instance list`` |
2482 |
- fix ``gnt-backup list`` with down nodes (issue 21) |
2483 |
- change the tools location (move from $pkgdatadir to $pkglibdir/tools) |
2484 |
- fix the dist archive and add a check for including svn/git files in |
2485 |
the future |
2486 |
- some developer-related changes: improve the burnin and the QA suite, |
2487 |
add an upload script for testing during development |
2488 |
|
2489 |
|
2490 |
Version 1.2.1 |

2496 |
"Initializing the cluster" |
2497 |
- allow for the PVM hypervisor per-instance kernel and initrd paths |
2498 |
- add a new command ``gnt-cluster verify-disks`` which uses a new |
2499 |
algorithm to improve the reconnection of the DRBD pairs if the device |
2500 |
on the secondary node has gone away |
2501 |
- make logical volume code auto-activate LVs at disk activation time |
2502 |
- slightly improve the speed of activating disks |
2503 |
- allow specification of the MAC address at instance creation time, and |
2504 |
changing it later via ``gnt-instance modify`` |
2505 |
- fix handling of external commands that generate lots of output on |
2506 |
stderr |
2507 |
- update documentation with regard to minimum version of DRBD8 supported |
2508 |
|
2509 |
|
2510 |
Version 1.2.0 |
2511 |
------------- |
2512 |
|
2513 |
*(Released Tue, 4 Dec 2007)* |
2514 |
|
2515 |
- Log the ``xm create`` output to the node daemon log on failure (to |
2516 |
help diagnosing the error) |
2517 |
- In debug mode, log all external commands output if failed to the logs |
2518 |
- Change parsing of lvm commands to ignore stderr |
2519 |
|

*(Released Tue, 13 Nov 2007)* |
2537 |
|
2538 |
- Change configuration file format from Python's Pickle to JSON. |
2539 |
Upgrading is possible using the cfgupgrade utility. |
2540 |
- Add support for DRBD 8.0 (new disk template ``drbd``) which allows for |
2541 |
faster replace disks and is more stable (DRBD 8 has many improvements |
2542 |
compared to DRBD 0.7) |
2543 |
- Added command line tags support (see man pages for ``gnt-instance``, |
2544 |
``gnt-node``, ``gnt-cluster``) |
2545 |
- Added instance rename support |
2546 |
- Added multi-instance startup/shutdown |
2547 |
- Added cluster rename support |
2548 |
- Added ``gnt-node evacuate`` to simplify some node operations |
2549 |
- Added instance reboot operation that can speedup reboot as compared to |
2550 |
stop and start |
2551 |
- Soften the requirement that hostnames are in FQDN format |
2552 |
- The ``ganeti-watcher`` now activates drbd pairs after secondary node |
2553 |
reboots |
2554 |
- Removed dependency on debian's patched fping that uses the |
2555 |
non-standard ``-S`` option |
2556 |
- Now the OS definitions are searched for in multiple, configurable |
2557 |
paths (easier for distros to package) |
2558 |
- Some changes to the hooks infrastructure (especially the new |
2559 |
post-configuration update hook) |
2560 |
- Other small bugfixes |
