| 58 | 58 |
parameters (all optional): |

spindles |

How many spindles (physical disks on the node) the disk should span. |

mode |

The access mode. Either ``ro`` (read-only) or the default ``rw`` |

(read-write). |

The ``--disk add:size=*SIZE*,[options..]`` option adds a disk to the |
| 1104 | 1107 |
instance, and ``--disk *N*:add:size=*SIZE*,[options..]`` will add a disk |
| 1105 | 1108 |
to the the instance at a specific index. The available options are the |
| 1106 |
same as in the **add** command(``mode``, ``name``, ``vg``, ``metavg``).
|
|
| 1107 |
When adding an ExtStorage disk the ``provider=*PROVIDER*`` option is
|
|
| 1108 |
also mandatory and specifies the ExtStorage provider. Also, for
|
|
| 1109 |
ExtStorage disks arbitrary parameters can be passed as additional comma
|
|
| 1110 |
separated options, same as in the **add** command. -The ``--disk remove``
|
|
| 1111 |
option will remove the last disk of the instance. Use
|
|
| 1112 |
``--disk `` *ID*``:remove`` to remove a disk by its identifier. *ID*
|
|
| 1113 |
can be the index of the disk, the disks's name or the disks's UUID. The
|
|
| 1114 |
``--disk *ID*:modify[,options...]`` will change the options of the disk.

same as in the **add** command(``spindles``, ``mode``, ``name``, ``vg``,

``metavg``). When adding an ExtStorage disk the ``provider=*PROVIDER*``
|
|

option is also mandatory and specifies the ExtStorage provider. Also,

comma separated options, same as in the **add** command. -The ``--disk

remove`` option will remove the last disk of the instance. Use ``--disk

`` *ID*``:remove`` to remove a disk by its identifier. *ID* can be the
|
|
| 1116 |
index of the disk, the disks's name or the disks's UUID. The ``--disk

|
| 1117 |
*ID*:modify[,options...]`` will change the options of the disk. |

If only a subset should be recreated, any number of ``disk`` options can |
| 1629 | 1632 |
be specified. It expects a disk index and an optional list of disk |
| 1630 |
parameters to change. Only ``size`` and ``mode`` can be changed while
|
|
| 1631 |
recreating disks. To recreate all disks while changing parameters on
|
|
| 1632 |
a subset only, a ``--disk`` option must be given for every disk of the

instance. |

disk of the instance.

Optionally the instance's disks can be recreated on different |
| 1636 | 1639 |
nodes. This can be useful if, for example, the original nodes of the |
