No. The sequence of events is that openais tells crmd that shutdown
is pending, then crmd will try to stop all resources which are running
on the node. It may happen, usually with resources which are broken for
whatever reason, that the shutdown is escalated and that crmd gives up
on waiting for resources to stop. At any rate, if you don't see log
messages of the form "lrmd.*stop.*<rsc>" then there is probably a bug.
Please make a hb_report and file a bugzilla.

Thanks,

Dejan
