the disks on the secondary node. For these two cases (as the |

node doesn't change), it is possible to only run the replace |

for a subset of the disks, using the option |
|

<option>--disks</option> which takes a list of |
|
| 1593 |
comma-delimited disk indices (zero-based), |
|
| 1594 |
e.g. <userinput>0,2</userinput> to replace only the first |

This command changes the role of the node. Each options takes |
|
| 519 |
either a literal <literal>yes</literal> or |
|
| 520 |
<literal>no</literal>, and only one option should be given as |
|
| 521 |
<literal>yes</literal>. The meaning of the roles are described |
|
| 522 |
in the manpage <citerefentry> |

In case a node is demoted from the master candidate role, but |
|
| 529 |
there are not enough new nodes for this case, the operation |
|
| 530 |
will be refused. To override this check, pass the |
|
| 531 |
<option>--force</option> option. |
