First, I think if a resource cannot be started on a node it's better to return
OCF_ERR_INSTALLED rather than OCF_NOT_RUNNING, because it does not make any
sense to try to start the resource on that particular node. Then, how would you
check in the resource agent that a resource it not to be run on the particular
node? I mean you can do it, but aren't you duplicating cluster decision logic
into the resource agent (where it doesn't belong to IMHO)?
