Recreates the disks of the given instance, or only a subset of the |
|
| 1372 |
disks (if the option ``disks`` is passed, which must be a |
|
| 1373 |
comma-separated list of disk indices, starting from zero). |
|
| 1371 |
Recreates all or a subset of disks of the given instance. |
|
| 1374 | 1372 |
|
| 1375 | 1373 |
Note that this functionality should only be used for missing disks; if |
| 1376 | 1374 |
any of the given disks already exists, the operation will fail. While |
| 1377 | 1375 |
this is suboptimal, recreate-disks should hopefully not be needed in |
| 1378 | 1376 |
normal operation and as such the impact of this is low. |
| 1379 | 1377 |
|
| 1378 |
If only a subset should be recreated, any number of ``disk`` options can |
|
| 1379 |
be specified. It expects a disk index and an optional list of disk |
|
| 1380 |
parameters to change. Only ``size`` and ``mode`` can be changed while |
|
| 1381 |
recreating disks. To recreate all disks while changing parameters on |
|
| 1382 |
a subset only, a ``--disk`` option must be given for every disk of the |
|
| 1383 |
instance. |
|
| 1384 |
|
|
| 1380 | 1385 |
Optionally the instance's disks can be recreated on different |
| 1381 | 1386 |
nodes. This can be useful if, for example, the original nodes of the |
| 1382 | 1387 |
instance have gone down (and are marked offline), so we can't recreate |
| 1383 | 1388 |
on the same nodes. To do this, pass the new node(s) via ``-n`` option, |
| 1384 | 1389 |
with a syntax similar to the **add** command. The number of nodes |
| 1385 | 1390 |
passed must equal the number of nodes that the instance currently |
| 1386 |
has. Note that changing nodes is only allowed for 'all disk'
|
|
| 1387 |
replacement (when ``--disks`` is not passed).
|
|
| 1391 |
has. Note that changing nodes is only allowed when all disks are
|
|
| 1392 |
replaced, e.g. when no ``--disk`` option is passed.

The ``--submit`` option is used to send the job to the master daemon |
| 1390 | 1395 |
but not wait for its completion. The job ID will be shown so that it |
