6 | 35dd762d | Michael Hanselmann | This document details the steps needed to upgrade a cluster to newer versions |
7 | 35dd762d | Michael Hanselmann | of Ganeti. |
8 | 35dd762d | Michael Hanselmann | |
9 | 35dd762d | Michael Hanselmann | As a general rule the node daemons need to be restarted after each software |
10 | 35dd762d | Michael Hanselmann | upgrade; if using the provided example init.d script, this means running the |
11 | 35dd762d | Michael Hanselmann | following command on all nodes:: |
12 | 35dd762d | Michael Hanselmann | |
13 | e1ff0de1 | Iustin Pop | $ /etc/init.d/ganeti restart |
14 | 35dd762d | Michael Hanselmann | |
15 | 98ef4a7b | Klaus Aehlig | 2.11 and above |
16 | 98ef4a7b | Klaus Aehlig | -------------- |
17 | 98ef4a7b | Klaus Aehlig | |
18 | 98ef4a7b | Klaus Aehlig | Starting from 2.10 onwards, Ganeti has support for parallely installed versions |
19 | 98ef4a7b | Klaus Aehlig | and automated upgrades. The default configuration for 2.11 and higher already is |
20 | 98ef4a7b | Klaus Aehlig | to install as a parallel version without changing the running version. If both |
21 | 98ef4a7b | Klaus Aehlig | versions, the installed one and the one to upgrade to, are 2.10 or higher, the |
22 | 98ef4a7b | Klaus Aehlig | actual switch of the live version can be carried out by the following command |
23 | 98ef4a7b | Klaus Aehlig | on the master node.:: |
24 | 98ef4a7b | Klaus Aehlig | |
25 | 98ef4a7b | Klaus Aehlig | $ gnt-cluster upgrade --to 2.11 |
26 | 98ef4a7b | Klaus Aehlig | |
27 | 98ef4a7b | Klaus Aehlig | This will carry out the steps described below in the section on upgrades from |
28 | 98ef4a7b | Klaus Aehlig | 2.1 and above. Downgrades to the previous minor version can be done in the same |
29 | 98ef4a7b | Klaus Aehlig | way, specifiying the smaller version on the ``--to`` argument. |

32 | 35dd762d | Michael Hanselmann | 2.1 and above |
33 | 35dd762d | Michael Hanselmann | ------------- |
34 | 35dd762d | Michael Hanselmann | |
35 | 35dd762d | Michael Hanselmann | Starting with Ganeti 2.0, upgrades between revisions (e.g. 2.1.0 to 2.1.1) |
36 | 35dd762d | Michael Hanselmann | should not need manual intervention. As a safety measure, minor releases (e.g. |
37 | 35dd762d | Michael Hanselmann | 2.1.3 to 2.2.0) require the ``cfgupgrade`` command for changing the |
38 | 35dd762d | Michael Hanselmann | configuration version. Below you find the steps necessary to upgrade between |
39 | 35dd762d | Michael Hanselmann | minor releases. |
40 | 35dd762d | Michael Hanselmann | |
41 | 35dd762d | Michael Hanselmann | To run commands on all nodes, the `distributed shell (dsh) |
42 | 35dd762d | Michael Hanselmann | <http://www.netfort.gr.jp/~dancer/software/dsh.html.en>`_ can be used, e.g. |
43 | 35dd762d | Michael Hanselmann | ``dsh -M -F 8 -f /var/lib/ganeti/ssconf_online_nodes gnt-cluster --version``. |
44 | 35dd762d | Michael Hanselmann | |
45 | 35dd762d | Michael Hanselmann | #. Ensure no jobs are running (master node only):: |
46 | 35dd762d | Michael Hanselmann | |
47 | e1ff0de1 | Iustin Pop | $ gnt-job list |
48 | 35dd762d | Michael Hanselmann | |
49 | 6c28c480 | Bernardo Dal Seno | #. Pause the watcher for an hour (master node only):: |
50 | 6c28c480 | Bernardo Dal Seno | |
51 | 6c28c480 | Bernardo Dal Seno | $ gnt-cluster watcher pause 1h |
52 | 6c28c480 | Bernardo Dal Seno | |
53 | 35dd762d | Michael Hanselmann | #. Stop all daemons on all nodes:: |

60 | 35dd762d | Michael Hanselmann | |
61 | 35dd762d | Michael Hanselmann | #. Install new Ganeti version on all nodes |
62 | 35dd762d | Michael Hanselmann | #. Run cfgupgrade on the master node:: |
63 | 35dd762d | Michael Hanselmann | |
64 | e1ff0de1 | Iustin Pop | $ /usr/lib/ganeti/tools/cfgupgrade --verbose --dry-run |
65 | e1ff0de1 | Iustin Pop | $ /usr/lib/ganeti/tools/cfgupgrade --verbose |
66 | 35dd762d | Michael Hanselmann | |
67 | 35dd762d | Michael Hanselmann | (``cfgupgrade`` supports a number of parameters, run it with |
68 | 35dd762d | Michael Hanselmann | ``--help`` for more information) |
69 | 35dd762d | Michael Hanselmann | |
70 | fe05a931 | Michele Tartara | #. Upgrade the directory permissions on all nodes:: |
71 | fe05a931 | Michele Tartara | |
72 | fe05a931 | Michele Tartara | $ /usr/lib/ganeti/ensure-dirs --full-run |
73 | fe05a931 | Michele Tartara | |
74 | 91cdc18f | Michele Tartara | #. Create the (missing) required users and make users part of the required |
75 | 3449551d | Michele Tartara | groups on all nodes:: |

108 | 91fb0d18 | Bernardo Dal Seno | Reverting an upgrade |
109 | 91fb0d18 | Bernardo Dal Seno | ~~~~~~~~~~~~~~~~~~~~ |
110 | 91fb0d18 | Bernardo Dal Seno | |
111 | 91fb0d18 | Bernardo Dal Seno | For going back between revisions (e.g. 2.1.1 to 2.1.0) no manual |
112 | 91fb0d18 | Bernardo Dal Seno | intervention is required, as for upgrades. |
113 | 91fb0d18 | Bernardo Dal Seno | |
114 | 91fb0d18 | Bernardo Dal Seno | Starting from version 2.8, ``cfgupgrade`` supports ``--downgrade`` |
115 | 91fb0d18 | Bernardo Dal Seno | option to bring the configuration back to the previous stable version. |
116 | 91fb0d18 | Bernardo Dal Seno | This is useful if you upgrade Ganeti and after some time you run into |
117 | 91fb0d18 | Bernardo Dal Seno | problems with the new version. You can downgrade the configuration |
118 | 91fb0d18 | Bernardo Dal Seno | without losing the changes made since the upgrade. Any feature not |
119 | 91fb0d18 | Bernardo Dal Seno | supported by the old version will be removed from the configuration, of |
120 | 91fb0d18 | Bernardo Dal Seno | course, but you get a warning about it. If there is any new feature and |
121 | 91fb0d18 | Bernardo Dal Seno | you haven't changed from its default value, you don't have to worry |
122 | 91fb0d18 | Bernardo Dal Seno | about it, as it will get the same value whenever you'll upgrade again. |
123 | 91fb0d18 | Bernardo Dal Seno | |
124 | 91fb0d18 | Bernardo Dal Seno | The procedure is similar to upgrading, but please notice that you have to |
125 | 91fb0d18 | Bernardo Dal Seno | revert the configuration **before** installing the old version. |
126 | 91fb0d18 | Bernardo Dal Seno | |
127 | 91fb0d18 | Bernardo Dal Seno | #. Ensure no jobs are running (master node only):: |
128 | 91fb0d18 | Bernardo Dal Seno | |
129 | 91fb0d18 | Bernardo Dal Seno | $ gnt-job list |
130 | 91fb0d18 | Bernardo Dal Seno | |
131 | 91fb0d18 | Bernardo Dal Seno | #. Pause the watcher for an hour (master node only):: |
132 | 91fb0d18 | Bernardo Dal Seno | |
133 | 91fb0d18 | Bernardo Dal Seno | $ gnt-cluster watcher pause 1h |
134 | 91fb0d18 | Bernardo Dal Seno | |
135 | 91fb0d18 | Bernardo Dal Seno | #. Stop all daemons on all nodes:: |
136 | 91fb0d18 | Bernardo Dal Seno | |
137 | 91fb0d18 | Bernardo Dal Seno | $ /etc/init.d/ganeti stop |
138 | 91fb0d18 | Bernardo Dal Seno | |
139 | 91fb0d18 | Bernardo Dal Seno | #. Backup old configuration (master node only):: |
140 | 91fb0d18 | Bernardo Dal Seno | |
141 | 91fb0d18 | Bernardo Dal Seno | $ tar czf /var/lib/ganeti-$(date +\%FT\%T).tar.gz -C /var/lib ganeti |
142 | 91fb0d18 | Bernardo Dal Seno | |
143 | 91fb0d18 | Bernardo Dal Seno | #. Run cfgupgrade on the master node:: |
144 | 91fb0d18 | Bernardo Dal Seno | |
145 | 91fb0d18 | Bernardo Dal Seno | $ /usr/lib/ganeti/tools/cfgupgrade --verbose --downgrade --dry-run |
146 | 91fb0d18 | Bernardo Dal Seno | $ /usr/lib/ganeti/tools/cfgupgrade --verbose --downgrade |
147 | 91fb0d18 | Bernardo Dal Seno | |
148 | 91fb0d18 | Bernardo Dal Seno | You may want to copy all the messages about features that have been |
149 | 91fb0d18 | Bernardo Dal Seno | removed during the downgrade, in case you want to restore them when |
150 | 91fb0d18 | Bernardo Dal Seno | upgrading again. |
151 | 91fb0d18 | Bernardo Dal Seno | |
152 | 91fb0d18 | Bernardo Dal Seno | #. Install the old Ganeti version on all nodes |
153 | f3c7b51c | Michele Tartara | |
154 | f3c7b51c | Michele Tartara | NB: in Ganeti 2.8, the ``cmdlib.py`` file was split into a series of files |
155 | f3c7b51c | Michele Tartara | contained in the ``cmdlib`` directory. If Ganeti is installed from sources |
156 | f3c7b51c | Michele Tartara | and not from a package, while downgrading Ganeti to a pre-2.8 |
157 | f3c7b51c | Michele Tartara | version it is important to remember to remove the ``cmdlib`` directory |
158 | f3c7b51c | Michele Tartara | from the directory containing the Ganeti python files (which usually is |
159 | f3c7b51c | Michele Tartara | ``${PREFIX}/lib/python${VERSION}/dist-packages/ganeti``). |
160 | f3c7b51c | Michele Tartara | A simpler upgrade/downgrade procedure will be made available in future |
161 | f3c7b51c | Michele Tartara | versions of Ganeti. |
162 | f3c7b51c | Michele Tartara | |
163 | 91fb0d18 | Bernardo Dal Seno | #. Restart daemons on all nodes:: |
164 | 91fb0d18 | Bernardo Dal Seno | |

184 | 35dd762d | Michael Hanselmann | 2.0 releases |
185 | 35dd762d | Michael Hanselmann | ------------ |
186 | 35dd762d | Michael Hanselmann | |
187 | 35dd762d | Michael Hanselmann | 2.0.3 to 2.0.4 |
188 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
189 | 35dd762d | Michael Hanselmann | |
190 | 35dd762d | Michael Hanselmann | No changes needed except restarting the daemon; but rollback to 2.0.3 might |
191 | 35dd762d | Michael Hanselmann | require configuration editing. |
192 | 35dd762d | Michael Hanselmann | |
193 | 35dd762d | Michael Hanselmann | If you're using Xen-HVM instances, please double-check the network |
194 | 35dd762d | Michael Hanselmann | configuration (``nic_type`` parameter) as the defaults might have changed: |
195 | 35dd762d | Michael Hanselmann | 2.0.4 adds any missing configuration items and depending on the version of the |
196 | 35dd762d | Michael Hanselmann | software the cluster has been installed with, some new keys might have been |
197 | 35dd762d | Michael Hanselmann | added. |
198 | 35dd762d | Michael Hanselmann | |
199 | 35dd762d | Michael Hanselmann | 2.0.1 to 2.0.2/2.0.3 |
200 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~ |
201 | 35dd762d | Michael Hanselmann | |
202 | 35dd762d | Michael Hanselmann | Between 2.0.1 and 2.0.2 there have been some changes in the handling of block |
203 | 35dd762d | Michael Hanselmann | devices, which can cause some issues. 2.0.3 was then released which adds two |
204 | 35dd762d | Michael Hanselmann | new options/commands to fix this issue. |
205 | 35dd762d | Michael Hanselmann | |
206 | 35dd762d | Michael Hanselmann | If you use DRBD-type instances and see problems in instance start or |
207 | 35dd762d | Michael Hanselmann | activate-disks with messages from DRBD about "lower device too small" or |
208 | 35dd762d | Michael Hanselmann | similar, it is recoomended to: |
209 | 35dd762d | Michael Hanselmann | |
210 | 35dd762d | Michael Hanselmann | #. Run ``gnt-instance activate-disks --ignore-size $instance`` for each |
211 | 35dd762d | Michael Hanselmann | of the affected instances |
212 | 35dd762d | Michael Hanselmann | #. Then run ``gnt-cluster repair-disk-sizes`` which will check that |
213 | 35dd762d | Michael Hanselmann | instances have the correct disk sizes |
214 | 35dd762d | Michael Hanselmann | |
215 | 35dd762d | Michael Hanselmann | 1.2 to 2.0 |
216 | 35dd762d | Michael Hanselmann | ---------- |
217 | 35dd762d | Michael Hanselmann | |
218 | 35dd762d | Michael Hanselmann | Prerequisites: |
219 | 35dd762d | Michael Hanselmann | |
220 | 35dd762d | Michael Hanselmann | - Ganeti 1.2.7 is currently installed |
221 | 35dd762d | Michael Hanselmann | - All instances have been migrated from DRBD 0.7 to DRBD 8.x (i.e. no |
222 | 35dd762d | Michael Hanselmann | ``remote_raid1`` disk template) |
223 | 35dd762d | Michael Hanselmann | - Upgrade to Ganeti 2.0.0~rc2 or later (~rc1 and earlier don't have the needed |
224 | 35dd762d | Michael Hanselmann | upgrade tool) |
225 | 35dd762d | Michael Hanselmann | |
226 | 35dd762d | Michael Hanselmann | In the below steps, replace :file:`/var/lib` with ``$libdir`` if Ganeti was not |
227 | 35dd762d | Michael Hanselmann | installed with this prefix (e.g. :file:`/usr/local/var`). Same for |
228 | 35dd762d | Michael Hanselmann | :file:`/usr/lib`. |
229 | 35dd762d | Michael Hanselmann | |
230 | 35dd762d | Michael Hanselmann | Execution (all steps are required in the order given): |
231 | 35dd762d | Michael Hanselmann | |
232 | 35dd762d | Michael Hanselmann | #. Make a backup of the current configuration, for safety:: |
233 | 35dd762d | Michael Hanselmann | |
234 | e1ff0de1 | Iustin Pop | $ cp -a /var/lib/ganeti /var/lib/ganeti-1.2.backup |
235 | 35dd762d | Michael Hanselmann | |
236 | 35dd762d | Michael Hanselmann | #. Stop all instances:: |
237 | 35dd762d | Michael Hanselmann | |
238 | e1ff0de1 | Iustin Pop | $ gnt-instance stop --all |
239 | 35dd762d | Michael Hanselmann | |
240 | 35dd762d | Michael Hanselmann | #. Make sure no DRBD device are in use, the following command should show no |
241 | 35dd762d | Michael Hanselmann | active minors:: |
242 | 35dd762d | Michael Hanselmann | |
243 | e1ff0de1 | Iustin Pop | $ gnt-cluster command grep cs: /proc/drbd | grep -v cs:Unconf |
244 | 35dd762d | Michael Hanselmann | |
245 | 35dd762d | Michael Hanselmann | #. Stop the node daemons and rapi daemon on all nodes (note: should be logged |
246 | 35dd762d | Michael Hanselmann | in not via the cluster name, but the master node name, as the command below |
247 | 35dd762d | Michael Hanselmann | will remove the cluster ip from the master node):: |
248 | 35dd762d | Michael Hanselmann | |
249 | e1ff0de1 | Iustin Pop | $ gnt-cluster command /etc/init.d/ganeti stop |
250 | 35dd762d | Michael Hanselmann | |
251 | 35dd762d | Michael Hanselmann | #. Install the new software on all nodes, either from packaging (if available) |
252 | 35dd762d | Michael Hanselmann | or from sources; the master daemon will not start but give error messages |
253 | 35dd762d | Michael Hanselmann | about wrong configuration file, which is normal |
254 | 35dd762d | Michael Hanselmann | #. Upgrade the configuration file:: |
255 | 35dd762d | Michael Hanselmann | |
256 | e1ff0de1 | Iustin Pop | $ /usr/lib/ganeti/tools/cfgupgrade12 -v --dry-run |
257 | e1ff0de1 | Iustin Pop | $ /usr/lib/ganeti/tools/cfgupgrade12 -v |
258 | 35dd762d | Michael Hanselmann | |
259 | 35dd762d | Michael Hanselmann | #. Make sure ``ganeti-noded`` is running on all nodes (and start it if |
260 | 35dd762d | Michael Hanselmann | not) |
261 | 35dd762d | Michael Hanselmann | #. Start the master daemon:: |
262 | 35dd762d | Michael Hanselmann | |
263 | e1ff0de1 | Iustin Pop | $ ganeti-masterd |
264 | 35dd762d | Michael Hanselmann | |
265 | 35dd762d | Michael Hanselmann | #. Check that a simple node-list works:: |
266 | 35dd762d | Michael Hanselmann | |
267 | e1ff0de1 | Iustin Pop | $ gnt-node list |
268 | 35dd762d | Michael Hanselmann | |
269 | 35dd762d | Michael Hanselmann | #. Redistribute updated configuration to all nodes:: |
270 | 35dd762d | Michael Hanselmann | |
271 | e1ff0de1 | Iustin Pop | $ gnt-cluster redist-conf |
272 | e1ff0de1 | Iustin Pop | $ gnt-cluster copyfile /var/lib/ganeti/known_hosts |
273 | 35dd762d | Michael Hanselmann | |
274 | 35dd762d | Michael Hanselmann | #. Optional: if needed, install RAPI-specific certificates under |

313 | 35dd762d | Michael Hanselmann | |
314 | 35dd762d | Michael Hanselmann | 1.2 releases |
315 | 35dd762d | Michael Hanselmann | ------------ |
316 | 35dd762d | Michael Hanselmann | |
317 | 35dd762d | Michael Hanselmann | 1.2.4 to any other higher 1.2 version |
318 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
319 | 35dd762d | Michael Hanselmann | |
320 | 35dd762d | Michael Hanselmann | No changes needed. Rollback will usually require manual edit of the |
321 | 35dd762d | Michael Hanselmann | configuration file. |
322 | 35dd762d | Michael Hanselmann | |
323 | 35dd762d | Michael Hanselmann | 1.2.3 to 1.2.4 |
324 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
325 | 35dd762d | Michael Hanselmann | |
326 | 35dd762d | Michael Hanselmann | No changes needed. Note that going back from 1.2.4 to 1.2.3 will require manual |
327 | 35dd762d | Michael Hanselmann | edit of the configuration file (since we added some HVM-related new |
328 | 35dd762d | Michael Hanselmann | attributes). |
329 | 35dd762d | Michael Hanselmann | |
330 | 35dd762d | Michael Hanselmann | 1.2.2 to 1.2.3 |
331 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
332 | 35dd762d | Michael Hanselmann | |
333 | 35dd762d | Michael Hanselmann | No changes needed. Note that the drbd7-to-8 upgrade tool does a disk format |
334 | 35dd762d | Michael Hanselmann | change for the DRBD metadata, so in theory this might be **risky**. It is |
335 | 35dd762d | Michael Hanselmann | advised to have (good) backups before doing the upgrade. |
336 | 35dd762d | Michael Hanselmann | |
337 | 35dd762d | Michael Hanselmann | 1.2.1 to 1.2.2 |
338 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
339 | 35dd762d | Michael Hanselmann | |
340 | 35dd762d | Michael Hanselmann | No changes needed. |
341 | 35dd762d | Michael Hanselmann | |
342 | 35dd762d | Michael Hanselmann | 1.2.0 to 1.2.1 |
343 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
344 | 35dd762d | Michael Hanselmann | |
345 | 35dd762d | Michael Hanselmann | No changes needed. Only some bugfixes and new additions that don't affect |
346 | 35dd762d | Michael Hanselmann | existing clusters. |
347 | 35dd762d | Michael Hanselmann | |
348 | 35dd762d | Michael Hanselmann | 1.2.0 beta 3 to 1.2.0 |
349 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~ |
350 | 35dd762d | Michael Hanselmann | |
351 | 35dd762d | Michael Hanselmann | No changes needed. |
352 | 35dd762d | Michael Hanselmann | |
353 | 35dd762d | Michael Hanselmann | 1.2.0 beta 2 to beta 3 |
354 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~~ |
355 | 35dd762d | Michael Hanselmann | |
356 | 35dd762d | Michael Hanselmann | No changes needed. A new version of the debian-etch-instance OS (0.3) has been |
357 | 35dd762d | Michael Hanselmann | released, but upgrading it is not required. |
358 | 35dd762d | Michael Hanselmann | |
359 | 35dd762d | Michael Hanselmann | 1.2.0 beta 1 to beta 2 |
360 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~~ |
361 | 35dd762d | Michael Hanselmann | |
362 | 35dd762d | Michael Hanselmann | Beta 2 switched the config file format to JSON. Steps to upgrade: |
363 | 35dd762d | Michael Hanselmann | |
364 | 35dd762d | Michael Hanselmann | #. Stop the daemons (``/etc/init.d/ganeti stop``) on all nodes |
365 | 35dd762d | Michael Hanselmann | #. Disable the cron job (default is :file:`/etc/cron.d/ganeti`) |
366 | 35dd762d | Michael Hanselmann | #. Install the new version |
367 | 35dd762d | Michael Hanselmann | #. Make a backup copy of the config file |
368 | 35dd762d | Michael Hanselmann | #. Upgrade the config file using the following command:: |
369 | 35dd762d | Michael Hanselmann | |
370 | e1ff0de1 | Iustin Pop | $ /usr/share/ganeti/cfgupgrade --verbose /var/lib/ganeti/config.data |
371 | 35dd762d | Michael Hanselmann | |
372 | 35dd762d | Michael Hanselmann | #. Start the daemons and run ``gnt-cluster info``, ``gnt-node list`` and |
373 | 35dd762d | Michael Hanselmann | ``gnt-instance list`` to check if the upgrade process finished successfully |
374 | 35dd762d | Michael Hanselmann | |
375 | 35dd762d | Michael Hanselmann | The OS definition also need to be upgraded. There is a new version of the |
376 | 35dd762d | Michael Hanselmann | debian-etch-instance OS (0.2) that goes along with beta 2. |
