with drbd comes a script called "drbddisk". It's usually installed in
/etc/ha.d/ressource.d and should be called by heartbeat as a resource
agent when failing over. It will take care of switching the drbd device
on the standby node to primary mode.
Mounting the device after switching to primary is handled by the
heartbeat resource agent "Filesystem".
