We use it here for AFS storage. One of the sysadmins set up
a linux cluster using the heartbeat software. Only one of the machines
in the cluster pair runs the AFS server at any given time.
A failover causes the service IP address to transfer to the other
machine, and the AFS server to start on that machine also.
Be very careful with DRBD -- we lost a bunch of data when it
decided to resync the disks the wrong way. You have to understand
how it decides to do resyncs and when.
