91 | a8083063 | Iustin Pop | The <option>-s</option> option specifies the disk size for |
92 | b9ac33e9 | Iustin Pop | the instance, in mebibytes (defaults to |
93 | b9ac33e9 | Iustin Pop | <constant>20480MiB</constant> = |
94 | b9ac33e9 | Iustin Pop | <constant>20GiB</constant>). You can also use one of the |

103 | b9ac33e9 | Iustin Pop | as <filename class="devicefile">/dev/sdb</filename>). The |
104 | b9ac33e9 | Iustin Pop | default is <constant>4096MiB</constant>. As for the disk |
105 | b9ac33e9 | Iustin Pop | size, you can specify other suffixes. |

330 | a8083063 | Iustin Pop | There is a subtle grouping about the available output |

332 | a8083063 | Iustin Pop | and <option>oper_ram</option> are configuration value and |
333 | a8083063 | Iustin Pop | not run-time values. So if you don't select any of the |
334 | a8083063 | Iustin Pop | <option>oper_*</option> fields, the query will be satisfied |
335 | a8083063 | Iustin Pop | instantly from the cluster configuration, without having to |
336 | a8083063 | Iustin Pop | ask the remote nodes for the data. This can be helpful for |

604 | a8083063 | Iustin Pop | De-activates the block devices of the given instance. Note |
605 | a8083063 | Iustin Pop | that if you run this command for a remote raid instance |
606 | a8083063 | Iustin Pop | type, while it is running, it will not be able to shutdown |
607 | a8083063 | Iustin Pop | the block devices on the primary node, but it will shutdown |
608 | a8083063 | Iustin Pop | the block devices on the secondary nodes, thus breaking the |
609 | a8083063 | Iustin Pop | replication. |

630 | a8083063 | Iustin Pop | Failover will fail the instance over its secondary |
631 | a8083063 | Iustin Pop | node. This works only for instances having a remote raid |
632 | a8083063 | Iustin Pop | disk layout. |

636 | a8083063 | Iustin Pop | Normally the failover will check the consistency of the |
637 | a8083063 | Iustin Pop | disks before failing over the instance. If you are trying to |
638 | a8083063 | Iustin Pop | migrate instances off a dead node, this will fail. Use the |
639 | a8083063 | Iustin Pop | <option>--ignore-consistency</option> option for this |
640 | a8083063 | Iustin Pop | purpose. |
