Hi Dejan, I 'm working with the IP resource as an example to test and get stonith up and running. The real resource I want HA for will be external storage and I need to be sure it doesn't get mounted simultaneously by 2 different nodes.

Fencing (stonith) is a sort of last resort measure to get the cluster back to a sane state. Why do you want to turn off a node just because one IP resource migrated?
