Well, if you stop corosync, it would appear to leave gracefully from
corosync's perspective so the other node should know that it didn't
fail. However, and I am not a pacemaker expert, I would guess that
pacemaker just saw the membership change that it wasn't expecting and
invoked a fence.

If you plan to remove a node, it is probably best to stop pacemaker,
then stop corosync.

Also, 'openais' is oooold. Is this an old cluster? Corosync came out of
the openais project.
