Hmm. I think I stumbled over exactly this problem when I was
experimenting with the drbd OCF RA and did some failover tests.

This is a really nasty bug and renders the cluster kinda useless,
because the failover node won't run the resources (that depend on
drbd) when the active node dies. Is this assumption correct?

If yes, I should stop using that broken dopd ASAP... :>
