Migrate will move the instance to its secondary node without |
| 1448 | 1449 |
shutdown. It only works for instances having the drbd8 disk template |
| ... | ... | |
| 1481 | 1482 |
If ``--ignore-ipolicy`` is given any instance policy violations occuring |
| 1482 | 1483 |
during this operation are ignored. |
| 1483 | 1484 |
|
| 1485 |
The ``--no-runtime-changes`` option forbids migrate to alter an |
|
| 1486 |
instance's runtime before migrating it (eg. ballooning an instance |
|
| 1487 |
down because the target node doesn't have enough available memory). |
|
| 1488 |

As for the **gnt-instance migrate** command, the options |
| 255 |
``--no-live`` and ``--migration-mode`` can be given to influence
|
|
| 256 |
the migration type. |
