Note: "permalinks" may not be as permanent as we would like,

Drbd will prevent data corruption on its own, but stonith with drbd can
give you increased uptime because there are cases when a standby drbd or
heartbeat will refuse to take over until the formerly active one has been
proven to be shut down.
