As Digimer said, you really need fencing when you are using DRBD. Otherwise
it's only a matter of time before your shared filesystem gets corrupted.

You also need an order constraint to be sure that the ClusterFS Filesystem
does not start until after the Master DRBD resource, and a colocation
constraint to ensure these are on the same node.
