121 | d3b4cf9f | Iustin Pop | The <option>disk</option> option specifies the parameters |
122 | d3b4cf9f | Iustin Pop | for the disks of the instance. The numbering of disks starts |
123 | d3b4cf9f | Iustin Pop | at zero, and at least one disk needs to be passed. For each |
124 | d3b4cf9f | Iustin Pop | disk, at least the size needs to be given, and optionally |
125 | d3b4cf9f | Iustin Pop | the access mode (read-only or the default of read-write) can |
126 | d3b4cf9f | Iustin Pop | also be specified. The size is interpreted (when no unit is |
127 | d3b4cf9f | Iustin Pop | given) in mebibytes. You can also use one of the suffixes |
128 | d3b4cf9f | Iustin Pop | <literal>m</literal>, <literal>g</literal> or |
129 | b9ac33e9 | Iustin Pop | <literal>t</literal> to specificy the exact the units used; |
130 | b9ac33e9 | Iustin Pop | these suffixes map to mebibytes, gibibytes and tebibytes. |

134 | c0e4a2c3 | Iustin Pop | Alternatively, a single-disk instance can be created via the |
135 | c0e4a2c3 | Iustin Pop | <option>-s</option> option which takes a single argument, |
136 | c0e4a2c3 | Iustin Pop | the size of the disk. This is similar to the Ganeti 1.2 |
137 | c0e4a2c3 | Iustin Pop | version (but will only create one disk). |

140 | c0e4a2c3 | Iustin Pop | <para> |
141 | d3b4cf9f | Iustin Pop | The minimum disk specification is therefore |
142 | c0e4a2c3 | Iustin Pop | <userinput>--disk 0:size=20G</userinput> (or <userinput>-s |
143 | c0e4a2c3 | Iustin Pop | 20G</userinput> when using the <option>-s</option> option), |
144 | c0e4a2c3 | Iustin Pop | and a three-disk instance can be specified as |
145 | c0e4a2c3 | Iustin Pop | <userinput>--disk 0:size=20G --disk 1:size=4G --disk |
146 | c0e4a2c3 | Iustin Pop | 2:size=100G</userinput>. |

150 | d3b4cf9f | Iustin Pop | The NICs of the instances can be specified via the |
151 | d3b4cf9f | Iustin Pop | <option>--nic</option> option. By default, one NIC is |
152 | d3b4cf9f | Iustin Pop | created for the instance, with a random MAC, and connected |
153 | d3b4cf9f | Iustin Pop | to the default bridge. Each NIC can take up to three |

589 | d3b4cf9f | Iustin Pop | <para>The blktap driver (for Xen hypervisors). In |
590 | d3b4cf9f | Iustin Pop | order to be able to use the blktap driver you should |
591 | d3b4cf9f | Iustin Pop | check if the 'blktapctrl' user space disk agent is |
592 | d3b4cf9f | Iustin Pop | running (usually automatically started via xend). This |
593 | d3b4cf9f | Iustin Pop | user-level disk I/O interface has the advantage of |
594 | d3b4cf9f | Iustin Pop | better performance. Especially if you use a network |
595 | d3b4cf9f | Iustin Pop | file system (e.g. NFS) to store your instances this is |
596 | d3b4cf9f | Iustin Pop | the recommended choice. |

1824 | 80de0e3f | Iustin Pop | Failover will fail the instance over its secondary |
1825 | bd028152 | Iustin Pop | node. This works only for instances having a drbd disk |

1829 | a8083063 | Iustin Pop | <para> |
1830 | a8083063 | Iustin Pop | Normally the failover will check the consistency of the |
1831 | 80de0e3f | Iustin Pop | disks before failing over the instance. If you are trying to |
1832 | a8083063 | Iustin Pop | migrate instances off a dead node, this will fail. Use the |
1833 | a8083063 | Iustin Pop | <option>--ignore-consistency</option> option for this |
1834 | 24a40d57 | Iustin Pop | purpose. Note that this option can be dangerous as errors in |
1835 | 24a40d57 | Iustin Pop | shutting down the instance will be ignored, resulting in |
1836 | 24a40d57 | Iustin Pop | possibly having the instance running on two machines in |
1837 | 24a40d57 | Iustin Pop | parallel (on disconnected DRBD drives). |

1873 | d3b4cf9f | Iustin Pop | Migrate will move the instance to its secondary node without |
1874 | d3b4cf9f | Iustin Pop | shutdown. It only works for instances having the drbd8 disk |

1878 | d3b4cf9f | Iustin Pop | <para> |
1879 | d3b4cf9f | Iustin Pop | The migration command needs a perfectly healthy instance, as |
1880 | d3b4cf9f | Iustin Pop | we rely on the dual-master capability of drbd8 and the disks |
1881 | d3b4cf9f | Iustin Pop | of the instance are not allowed to be degraded. |

1885 | d3b4cf9f | Iustin Pop | The <option>--non-live</option> option will switch (for the |
1886 | d3b4cf9f | Iustin Pop | hypervisors that support it) between a "fully live" |
1887 | d3b4cf9f | Iustin Pop | (i.e. the interruption is as minimal as possible) migration |
1888 | d3b4cf9f | Iustin Pop | and one in which the instance is frozen, its state saved and |
1889 | d3b4cf9f | Iustin Pop | transported to the remote node, and then resumed there. This |
1890 | d3b4cf9f | Iustin Pop | all depends on the hypervisor support for two different |
1891 | d3b4cf9f | Iustin Pop | methods. In any case, it is not an error to pass this |
1892 | d3b4cf9f | Iustin Pop | parameter (it will just be ignored if the hypervisor doesn't |
1893 | d3b4cf9f | Iustin Pop | support it). |

1897 | d3b4cf9f | Iustin Pop | If the <option>--cleanup</option> option is passed, the |
1898 | d3b4cf9f | Iustin Pop | operation changes from migration to attempting recovery from |
1899 | d3b4cf9f | Iustin Pop | a failed previous migration. In this mode, ganeti checks if |
1900 | d3b4cf9f | Iustin Pop | the instance runs on the correct node (and updates its |
1901 | d3b4cf9f | Iustin Pop | configuration if not) and ensures the instances's disks are |
1902 | d3b4cf9f | Iustin Pop | configured correctly. In this mode, the |
1903 | d3b4cf9f | Iustin Pop | <option>--non-live</option> option is ignored. |
