I have a pair of centos 6 systems, with a rather large raid thats DRBD 
replicated from box 1 to box 2... box 1 mounts this as /data

when box 1 reboots, /data doesn't get mounted, but the drbd replication 
starts up just fine.   the entry in fstab is...

/dev/drbd0              /data           xfs     inode64         1 0

once the system is booted up, if I `mount /data`, it mounts just fine.

I'm not using any sort of heartbeat or other HA management software, if 
box 1 fails, I'll manually configure box2 to take over after physically 
disabling box1 so it can't wake up a zombie.
