Indeed.  That is my understanding too, and further, if heartbeat finds a
resource already running on a node on which it's trying to start it
stops and throws it's hands up.  When the O/S is starting LVM, both
nodes end up doing that.

I suppose ultimately this is not unlike not having the lustre devices
in /etc/fstab (set to automount, anyway) when using heartbeat because
you know heartbeat is going to do the mount.
