Depends on the plugin, i.e. if it supports multiple hostnames. Most support only one and in that case obviously you need two resources (clones won't make sense in that case). > Until now I have no pingd resource.

Typical cases for fencing is if we can't talk to a node, hence we don't know what's going on there, and if a resource fails to stop, because then we don't know in which state that resource is. There could be others. For example, you can set on-fail="fence" for any operation on any resource. Thanks, Dejan P.S. See the other recent post and take a look at the document.
