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. |

33 | 898fd9e1 | Helga Velroyen | ---- |
34 | 898fd9e1 | Helga Velroyen | |
35 | 898fd9e1 | Helga Velroyen | When upgrading to 2.11, first apply the instructions of ``2.11 and |
36 | 898fd9e1 | Helga Velroyen | above``. 2.11 comes with the new feature of enhanced RPC security |
37 | 898fd9e1 | Helga Velroyen | through client certificates. This features needs to be enabled after the |
38 | 898fd9e1 | Helga Velroyen | upgrade by:: |
39 | 898fd9e1 | Helga Velroyen | |
40 | 898fd9e1 | Helga Velroyen | $ gnt-cluster renew-crypto --new-node-certificates |
41 | 898fd9e1 | Helga Velroyen | |
42 | 898fd9e1 | Helga Velroyen | |
43 | 35dd762d | Michael Hanselmann | 2.1 and above |
44 | 35dd762d | Michael Hanselmann | ------------- |
45 | 35dd762d | Michael Hanselmann | |
46 | 35dd762d | Michael Hanselmann | Starting with Ganeti 2.0, upgrades between revisions (e.g. 2.1.0 to 2.1.1) |
47 | 35dd762d | Michael Hanselmann | should not need manual intervention. As a safety measure, minor releases (e.g. |
48 | 35dd762d | Michael Hanselmann | 2.1.3 to 2.2.0) require the ``cfgupgrade`` command for changing the |
49 | 35dd762d | Michael Hanselmann | configuration version. Below you find the steps necessary to upgrade between |
50 | 35dd762d | Michael Hanselmann | minor releases. |
51 | 35dd762d | Michael Hanselmann | |
52 | 35dd762d | Michael Hanselmann | To run commands on all nodes, the `distributed shell (dsh) |
53 | 35dd762d | Michael Hanselmann | <http://www.netfort.gr.jp/~dancer/software/dsh.html.en>`_ can be used, e.g. |
54 | 35dd762d | Michael Hanselmann | ``dsh -M -F 8 -f /var/lib/ganeti/ssconf_online_nodes gnt-cluster --version``. |
55 | 35dd762d | Michael Hanselmann | |

76 | e1ff0de1 | Iustin Pop | $ /usr/lib/ganeti/tools/cfgupgrade --verbose |
77 | 35dd762d | Michael Hanselmann | |
78 | 35dd762d | Michael Hanselmann | (``cfgupgrade`` supports a number of parameters, run it with |
79 | 35dd762d | Michael Hanselmann | ``--help`` for more information) |
80 | 35dd762d | Michael Hanselmann | |

119 | 91fb0d18 | Bernardo Dal Seno | Reverting an upgrade |
120 | 91fb0d18 | Bernardo Dal Seno | ~~~~~~~~~~~~~~~~~~~~ |
121 | 91fb0d18 | Bernardo Dal Seno | |
122 | 91fb0d18 | Bernardo Dal Seno | For going back between revisions (e.g. 2.1.1 to 2.1.0) no manual |
123 | 91fb0d18 | Bernardo Dal Seno | intervention is required, as for upgrades. |
124 | 91fb0d18 | Bernardo Dal Seno | |
125 | 91fb0d18 | Bernardo Dal Seno | Starting from version 2.8, ``cfgupgrade`` supports ``--downgrade`` |
126 | 91fb0d18 | Bernardo Dal Seno | option to bring the configuration back to the previous stable version. |
127 | 91fb0d18 | Bernardo Dal Seno | This is useful if you upgrade Ganeti and after some time you run into |
128 | 91fb0d18 | Bernardo Dal Seno | problems with the new version. You can downgrade the configuration |
129 | 91fb0d18 | Bernardo Dal Seno | without losing the changes made since the upgrade. Any feature not |
130 | 91fb0d18 | Bernardo Dal Seno | supported by the old version will be removed from the configuration, of |
131 | 91fb0d18 | Bernardo Dal Seno | course, but you get a warning about it. If there is any new feature and |
132 | 91fb0d18 | Bernardo Dal Seno | you haven't changed from its default value, you don't have to worry |
133 | 91fb0d18 | Bernardo Dal Seno | about it, as it will get the same value whenever you'll upgrade again. |
134 | 91fb0d18 | Bernardo Dal Seno | |

136 | df89787b | Klaus Aehlig | .................... |
137 | df89787b | Klaus Aehlig | |
138 | df89787b | Klaus Aehlig | From version 2.11 onwards, downgrades can be done by using the |
139 | df89787b | Klaus Aehlig | ``gnt-cluster upgrade`` command.:: |
140 | df89787b | Klaus Aehlig | |
141 | df89787b | Klaus Aehlig | gnt-cluster upgrade --to 2.10 |
142 | df89787b | Klaus Aehlig | |
143 | df89787b | Klaus Aehlig | Manual downgrades |
144 | df89787b | Klaus Aehlig | ................. |
145 | df89787b | Klaus Aehlig | |
146 | 91fb0d18 | Bernardo Dal Seno | The procedure is similar to upgrading, but please notice that you have to |
147 | 91fb0d18 | Bernardo Dal Seno | revert the configuration **before** installing the old version. |
148 | 91fb0d18 | Bernardo Dal Seno | |
149 | 91fb0d18 | Bernardo Dal Seno | #. Ensure no jobs are running (master node only):: |
150 | 91fb0d18 | Bernardo Dal Seno | |
151 | 91fb0d18 | Bernardo Dal Seno | $ gnt-job list |
152 | 91fb0d18 | Bernardo Dal Seno | |
153 | 91fb0d18 | Bernardo Dal Seno | #. Pause the watcher for an hour (master node only):: |
154 | 91fb0d18 | Bernardo Dal Seno | |
155 | 91fb0d18 | Bernardo Dal Seno | $ gnt-cluster watcher pause 1h |
156 | 91fb0d18 | Bernardo Dal Seno | |
157 | 91fb0d18 | Bernardo Dal Seno | #. Stop all daemons on all nodes:: |
158 | 91fb0d18 | Bernardo Dal Seno | |
159 | 91fb0d18 | Bernardo Dal Seno | $ /etc/init.d/ganeti stop |
160 | 91fb0d18 | Bernardo Dal Seno | |
161 | 91fb0d18 | Bernardo Dal Seno | #. Backup old configuration (master node only):: |
162 | 91fb0d18 | Bernardo Dal Seno | |
163 | 91fb0d18 | Bernardo Dal Seno | $ tar czf /var/lib/ganeti-$(date +\%FT\%T).tar.gz -C /var/lib ganeti |
164 | 91fb0d18 | Bernardo Dal Seno | |
165 | 91fb0d18 | Bernardo Dal Seno | #. Run cfgupgrade on the master node:: |
166 | 91fb0d18 | Bernardo Dal Seno | |
167 | 91fb0d18 | Bernardo Dal Seno | $ /usr/lib/ganeti/tools/cfgupgrade --verbose --downgrade --dry-run |
168 | 91fb0d18 | Bernardo Dal Seno | $ /usr/lib/ganeti/tools/cfgupgrade --verbose --downgrade |
169 | 91fb0d18 | Bernardo Dal Seno | |
170 | 91fb0d18 | Bernardo Dal Seno | You may want to copy all the messages about features that have been |
171 | 91fb0d18 | Bernardo Dal Seno | removed during the downgrade, in case you want to restore them when |
172 | 91fb0d18 | Bernardo Dal Seno | upgrading again. |
173 | 91fb0d18 | Bernardo Dal Seno | |
174 | 91fb0d18 | Bernardo Dal Seno | #. Install the old Ganeti version on all nodes |
175 | f3c7b51c | Michele Tartara | |
176 | f3c7b51c | Michele Tartara | NB: in Ganeti 2.8, the ``cmdlib.py`` file was split into a series of files |
177 | f3c7b51c | Michele Tartara | contained in the ``cmdlib`` directory. If Ganeti is installed from sources |
178 | f3c7b51c | Michele Tartara | and not from a package, while downgrading Ganeti to a pre-2.8 |
179 | f3c7b51c | Michele Tartara | version it is important to remember to remove the ``cmdlib`` directory |
180 | f3c7b51c | Michele Tartara | from the directory containing the Ganeti python files (which usually is |
181 | f3c7b51c | Michele Tartara | ``${PREFIX}/lib/python${VERSION}/dist-packages/ganeti``). |
182 | f3c7b51c | Michele Tartara | A simpler upgrade/downgrade procedure will be made available in future |
183 | f3c7b51c | Michele Tartara | versions of Ganeti. |
184 | f3c7b51c | Michele Tartara | |

207 | b18409cf | Klaus Aehlig | |
208 | b18409cf | Klaus Aehlig | After running ``cfgupgrade``, the ``client.pem`` and |
209 | b18409cf | Klaus Aehlig | ``ssconf_master_candidates_certs`` files need to be removed |
210 | b18409cf | Klaus Aehlig | from Ganeti's data directory on all nodes. While this step is |
211 | b18409cf | Klaus Aehlig | not necessary for 2.10 to run cleanly, leaving them will cause |
212 | b18409cf | Klaus Aehlig | problems when upgrading again after the downgrade. |

214 | 35dd762d | Michael Hanselmann | 2.0 releases |
215 | 35dd762d | Michael Hanselmann | ------------ |
216 | 35dd762d | Michael Hanselmann | |
217 | 35dd762d | Michael Hanselmann | 2.0.3 to 2.0.4 |
218 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
219 | 35dd762d | Michael Hanselmann | |
220 | 35dd762d | Michael Hanselmann | No changes needed except restarting the daemon; but rollback to 2.0.3 might |
221 | 35dd762d | Michael Hanselmann | require configuration editing. |
222 | 35dd762d | Michael Hanselmann | |
223 | 35dd762d | Michael Hanselmann | If you're using Xen-HVM instances, please double-check the network |
224 | 35dd762d | Michael Hanselmann | configuration (``nic_type`` parameter) as the defaults might have changed: |
225 | 35dd762d | Michael Hanselmann | 2.0.4 adds any missing configuration items and depending on the version of the |
226 | 35dd762d | Michael Hanselmann | software the cluster has been installed with, some new keys might have been |
227 | 35dd762d | Michael Hanselmann | added. |
228 | 35dd762d | Michael Hanselmann | |
229 | 35dd762d | Michael Hanselmann | 2.0.1 to 2.0.2/2.0.3 |
230 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~ |
231 | 35dd762d | Michael Hanselmann | |
232 | 35dd762d | Michael Hanselmann | Between 2.0.1 and 2.0.2 there have been some changes in the handling of block |
233 | 35dd762d | Michael Hanselmann | devices, which can cause some issues. 2.0.3 was then released which adds two |
234 | 35dd762d | Michael Hanselmann | new options/commands to fix this issue. |
235 | 35dd762d | Michael Hanselmann | |
236 | 35dd762d | Michael Hanselmann | If you use DRBD-type instances and see problems in instance start or |
237 | 35dd762d | Michael Hanselmann | activate-disks with messages from DRBD about "lower device too small" or |
238 | 35dd762d | Michael Hanselmann | similar, it is recoomended to: |
239 | 35dd762d | Michael Hanselmann | |
240 | 35dd762d | Michael Hanselmann | #. Run ``gnt-instance activate-disks --ignore-size $instance`` for each |
241 | 35dd762d | Michael Hanselmann | of the affected instances |
242 | 35dd762d | Michael Hanselmann | #. Then run ``gnt-cluster repair-disk-sizes`` which will check that |
243 | 35dd762d | Michael Hanselmann | instances have the correct disk sizes |
244 | 35dd762d | Michael Hanselmann | |
245 | 35dd762d | Michael Hanselmann | 1.2 to 2.0 |
246 | 35dd762d | Michael Hanselmann | ---------- |
247 | 35dd762d | Michael Hanselmann | |
248 | 35dd762d | Michael Hanselmann | Prerequisites: |
249 | 35dd762d | Michael Hanselmann | |
250 | 35dd762d | Michael Hanselmann | - Ganeti 1.2.7 is currently installed |
251 | 35dd762d | Michael Hanselmann | - All instances have been migrated from DRBD 0.7 to DRBD 8.x (i.e. no |
252 | 35dd762d | Michael Hanselmann | ``remote_raid1`` disk template) |
253 | 35dd762d | Michael Hanselmann | - Upgrade to Ganeti 2.0.0~rc2 or later (~rc1 and earlier don't have the needed |
254 | 35dd762d | Michael Hanselmann | upgrade tool) |
255 | 35dd762d | Michael Hanselmann | |
256 | 35dd762d | Michael Hanselmann | In the below steps, replace :file:`/var/lib` with ``$libdir`` if Ganeti was not |
257 | 35dd762d | Michael Hanselmann | installed with this prefix (e.g. :file:`/usr/local/var`). Same for |
258 | 35dd762d | Michael Hanselmann | :file:`/usr/lib`. |
259 | 35dd762d | Michael Hanselmann | |
260 | 35dd762d | Michael Hanselmann | Execution (all steps are required in the order given): |
261 | 35dd762d | Michael Hanselmann | |
262 | 35dd762d | Michael Hanselmann | #. Make a backup of the current configuration, for safety:: |
263 | 35dd762d | Michael Hanselmann | |
264 | e1ff0de1 | Iustin Pop | $ cp -a /var/lib/ganeti /var/lib/ganeti-1.2.backup |
265 | 35dd762d | Michael Hanselmann | |
266 | 35dd762d | Michael Hanselmann | #. Stop all instances:: |
267 | 35dd762d | Michael Hanselmann | |
268 | e1ff0de1 | Iustin Pop | $ gnt-instance stop --all |
269 | 35dd762d | Michael Hanselmann | |
270 | 35dd762d | Michael Hanselmann | #. Make sure no DRBD device are in use, the following command should show no |
271 | 35dd762d | Michael Hanselmann | active minors:: |
272 | 35dd762d | Michael Hanselmann | |
273 | e1ff0de1 | Iustin Pop | $ gnt-cluster command grep cs: /proc/drbd | grep -v cs:Unconf |
274 | 35dd762d | Michael Hanselmann | |

276 | 35dd762d | Michael Hanselmann | in not via the cluster name, but the master node name, as the command below |
277 | 35dd762d | Michael Hanselmann | will remove the cluster ip from the master node):: |
278 | 35dd762d | Michael Hanselmann | |
279 | e1ff0de1 | Iustin Pop | $ gnt-cluster command /etc/init.d/ganeti stop |
280 | 35dd762d | Michael Hanselmann | |
281 | 35dd762d | Michael Hanselmann | #. Install the new software on all nodes, either from packaging (if available) |
282 | 35dd762d | Michael Hanselmann | or from sources; the master daemon will not start but give error messages |
283 | 35dd762d | Michael Hanselmann | about wrong configuration file, which is normal |
284 | 35dd762d | Michael Hanselmann | #. Upgrade the configuration file:: |

289 | 35dd762d | Michael Hanselmann | #. Make sure ``ganeti-noded`` is running on all nodes (and start it if |
290 | 35dd762d | Michael Hanselmann | not) |
291 | 35dd762d | Michael Hanselmann | #. Start the master daemon:: |
292 | 35dd762d | Michael Hanselmann | |
293 | e1ff0de1 | Iustin Pop | $ ganeti-masterd |
294 | 35dd762d | Michael Hanselmann | |

303 | 35dd762d | Michael Hanselmann | |
304 | 35dd762d | Michael Hanselmann | #. Optional: if needed, install RAPI-specific certificates under |
305 | 35dd762d | Michael Hanselmann | :file:`/var/lib/ganeti/rapi.pem` and run:: |
306 | 35dd762d | Michael Hanselmann | |
307 | e1ff0de1 | Iustin Pop | $ gnt-cluster copyfile /var/lib/ganeti/rapi.pem |
308 | 35dd762d | Michael Hanselmann | |
309 | 35dd762d | Michael Hanselmann | #. Run a cluster verify, this should show no problems:: |
310 | 35dd762d | Michael Hanselmann | |
311 | e1ff0de1 | Iustin Pop | $ gnt-cluster verify |
312 | 35dd762d | Michael Hanselmann | |
313 | 35dd762d | Michael Hanselmann | #. Remove some obsolete files:: |
314 | 35dd762d | Michael Hanselmann | |
315 | e1ff0de1 | Iustin Pop | $ gnt-cluster command rm /var/lib/ganeti/ssconf_node_pass |
316 | e1ff0de1 | Iustin Pop | $ gnt-cluster command rm /var/lib/ganeti/ssconf_hypervisor |
317 | 35dd762d | Michael Hanselmann | |
318 | 35dd762d | Michael Hanselmann | #. Update the xen pvm (if this was a pvm cluster) setting for 1.2 |
319 | 35dd762d | Michael Hanselmann | compatibility:: |
320 | 35dd762d | Michael Hanselmann | |
321 | e1ff0de1 | Iustin Pop | $ gnt-cluster modify -H xen-pvm:root_path=/dev/sda |
322 | 35dd762d | Michael Hanselmann | |
323 | 35dd762d | Michael Hanselmann | #. Depending on your setup, you might also want to reset the initrd parameter:: |
324 | 35dd762d | Michael Hanselmann | |
325 | e1ff0de1 | Iustin Pop | $ gnt-cluster modify -H xen-pvm:initrd_path=/boot/initrd-2.6-xenU |
326 | 35dd762d | Michael Hanselmann | |
327 | 35dd762d | Michael Hanselmann | #. Reset the instance autobalance setting to default:: |
328 | 35dd762d | Michael Hanselmann | |
329 | e1ff0de1 | Iustin Pop | $ for i in $(gnt-instance list -o name --no-headers); do \ |
330 | e1ff0de1 | Iustin Pop | gnt-instance modify -B auto_balance=default $i; \ |
331 | e1ff0de1 | Iustin Pop | done |
332 | 35dd762d | Michael Hanselmann | |
333 | 35dd762d | Michael Hanselmann | #. Optional: start the RAPI demon:: |

335 | e1ff0de1 | Iustin Pop | $ ganeti-rapi |
336 | 35dd762d | Michael Hanselmann | |
337 | 35dd762d | Michael Hanselmann | #. Restart instances:: |

339 | e1ff0de1 | Iustin Pop | $ gnt-instance start --force-multiple --all |
340 | 35dd762d | Michael Hanselmann | |
341 | 35dd762d | Michael Hanselmann | At this point, ``gnt-cluster verify`` should show no errors and the migration |
342 | 35dd762d | Michael Hanselmann | is complete. |
343 | 35dd762d | Michael Hanselmann | |
344 | 35dd762d | Michael Hanselmann | 1.2 releases |
345 | 35dd762d | Michael Hanselmann | ------------ |
346 | 35dd762d | Michael Hanselmann | |
347 | 35dd762d | Michael Hanselmann | 1.2.4 to any other higher 1.2 version |
348 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
349 | 35dd762d | Michael Hanselmann | |
350 | 35dd762d | Michael Hanselmann | No changes needed. Rollback will usually require manual edit of the |
351 | 35dd762d | Michael Hanselmann | configuration file. |
352 | 35dd762d | Michael Hanselmann | |
353 | 35dd762d | Michael Hanselmann | 1.2.3 to 1.2.4 |
354 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
355 | 35dd762d | Michael Hanselmann | |
356 | 35dd762d | Michael Hanselmann | No changes needed. Note that going back from 1.2.4 to 1.2.3 will require manual |
357 | 35dd762d | Michael Hanselmann | edit of the configuration file (since we added some HVM-related new |
358 | 35dd762d | Michael Hanselmann | attributes). |
359 | 35dd762d | Michael Hanselmann | |
360 | 35dd762d | Michael Hanselmann | 1.2.2 to 1.2.3 |
361 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
362 | 35dd762d | Michael Hanselmann | |
363 | 35dd762d | Michael Hanselmann | No changes needed. Note that the drbd7-to-8 upgrade tool does a disk format |
364 | 35dd762d | Michael Hanselmann | change for the DRBD metadata, so in theory this might be **risky**. It is |
365 | 35dd762d | Michael Hanselmann | advised to have (good) backups before doing the upgrade. |
366 | 35dd762d | Michael Hanselmann | |
367 | 35dd762d | Michael Hanselmann | 1.2.1 to 1.2.2 |
368 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
369 | 35dd762d | Michael Hanselmann | |
370 | 35dd762d | Michael Hanselmann | No changes needed. |
371 | 35dd762d | Michael Hanselmann | |
372 | 35dd762d | Michael Hanselmann | 1.2.0 to 1.2.1 |
373 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~ |
374 | 35dd762d | Michael Hanselmann | |
375 | 35dd762d | Michael Hanselmann | No changes needed. Only some bugfixes and new additions that don't affect |
376 | 35dd762d | Michael Hanselmann | existing clusters. |
377 | 35dd762d | Michael Hanselmann | |
378 | 35dd762d | Michael Hanselmann | 1.2.0 beta 3 to 1.2.0 |
379 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~ |
380 | 35dd762d | Michael Hanselmann | |
381 | 35dd762d | Michael Hanselmann | No changes needed. |
382 | 35dd762d | Michael Hanselmann | |
383 | 35dd762d | Michael Hanselmann | 1.2.0 beta 2 to beta 3 |
384 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~~ |
385 | 35dd762d | Michael Hanselmann | |
386 | 35dd762d | Michael Hanselmann | No changes needed. A new version of the debian-etch-instance OS (0.3) has been |
387 | 35dd762d | Michael Hanselmann | released, but upgrading it is not required. |
388 | 35dd762d | Michael Hanselmann | |
389 | 35dd762d | Michael Hanselmann | 1.2.0 beta 1 to beta 2 |
390 | 35dd762d | Michael Hanselmann | ~~~~~~~~~~~~~~~~~~~~~~ |
391 | 35dd762d | Michael Hanselmann | |
392 | 35dd762d | Michael Hanselmann | Beta 2 switched the config file format to JSON. Steps to upgrade: |
393 | 35dd762d | Michael Hanselmann | |
394 | 35dd762d | Michael Hanselmann | #. Stop the daemons (``/etc/init.d/ganeti stop``) on all nodes |
395 | 35dd762d | Michael Hanselmann | #. Disable the cron job (default is :file:`/etc/cron.d/ganeti`) |
396 | 35dd762d | Michael Hanselmann | #. Install the new version |
397 | 35dd762d | Michael Hanselmann | #. Make a backup copy of the config file |
398 | 35dd762d | Michael Hanselmann | #. Upgrade the config file using the following command:: |
399 | 35dd762d | Michael Hanselmann | |
400 | e1ff0de1 | Iustin Pop | $ /usr/share/ganeti/cfgupgrade --verbose /var/lib/ganeti/config.data |
401 | 35dd762d | Michael Hanselmann | |
402 | 35dd762d | Michael Hanselmann | #. Start the daemons and run ``gnt-cluster info``, ``gnt-node list`` and |
403 | 35dd762d | Michael Hanselmann | ``gnt-instance list`` to check if the upgrade process finished successfully |
404 | 35dd762d | Michael Hanselmann | |
405 | 35dd762d | Michael Hanselmann | The OS definition also need to be upgraded. There is a new version of the |
406 | 35dd762d | Michael Hanselmann | debian-etch-instance OS (0.2) that goes along with beta 2. |
