[ClusterLabs] Fwd: Resource failure

[Digimer]

Stonith, in short, puts a node that has entered an unknown state (or a
service is it running enters a unknown state) into a known state,
usually by force-rebooting the node. How this is actually done depends
on what hardware (or hypervisor) your nodes are using.

So for me to offer any additional advice, you need to tell us what you
nodes are built on.
