EPO

~~~

**epo** [--on] [--groups|--all] *arguments*

Performs an emergency power-off on nodes given as arguments. If ``--groups``

is given, arguments are node groups. If ``--all`` is provided, the whole

cluster will be shut down.

The ``--on`` flag recovers the cluster after an emergency power-off

Please note that the master node will not be turned down or up automatically.

It will just be left in a state, where you can manully perform the shutdown of

that one node. If the master is in the list of affected nodes and this is not a

complete cluster emergency power-off (e.g. using ``--all``), you're required to

do a master failover to another node not affected.
