.. note:: this command only stores a local flag file, and if you |

failover the master, it will not have effect on the new master. |

If the cluster parameter ``maintain_node_health`` is enabled (see the |
|
| 1065 |
manpage for :command:`gnt-cluster`, the init and modify subcommands), |
|
| 1066 |
then the following will happen automatically: |
|
| 1067 |
|
|
| 1068 |
- the watcher will shutdown any instances running on offline nodes |
|
| 1069 |
- the watcher will deactivate any DRBD devices on offline nodes |
|
| 1070 |
|
|
| 1071 |
In the future, more actions are planned, so only enable this parameter |
|
| 1072 |
if the nodes are completely dedicated to Ganeti; otherwise it might be |
|
| 1073 |
possible to lose data due to auto-maintenance actions. |
