That looks like a problem in the resource agent. Most probably
you hit the bug 2219 which has been fixed on November 9.

My recommendation would be to stay with the OCF resource agents
whenever possible. Those should be in general of higher quality
than init scripts.

This has most probably been from the crm shell. It has been relaxed
in the meantime (see bugzilla 2222).

Yes, that's what I expected the right usage would be.
