| Program: ``gnt-cluster`` |
|
59 |
| Command: ``epo`` |
|
60 |
| Parameter: ``--on`` ``--force`` ``--groups`` ``--all`` |
|
61 |
| Options: ``--on``: By default epo turns off, with ``--on`` it tries to get the |
|
62 |
| cluster back online |
|
63 |
| ``--force``: To force the operation without asking for confirmation |
|
64 |
| ``--groups``: To operate on groups instead of nodes |
|
65 |
| ``--all``: To operate on the whole cluster |
|
66 |
|
|
67 |
This is a convenience command to allow easy emergency power off of a whole |
|
68 |
cluster or part of it. It takes care of all steps needed to get the cluster into |
|
69 |
a sane state to turn off the nodes. |
|
70 |
|
|
71 |
With ``--on`` it does the reverse and tries to bring the rest of the cluster back |
|
72 |
to life. |

.. note:: |
|
75 |
The master node is not able to shut itself cleanly down. Therefore, this |
|
76 |
command will not do all the work on single node clusters. On multi node |
|
77 |
clusters the command tries to find another master or if that is not possible |
|
78 |
prepares everything to the point where the user has to shutdown the master |
|
79 |
node itself alone this applies also to the single node cluster configuration. |
