You should run 'fence_ack_manual' on the surviving node (you've obviously
just restarted the failed node by pressing its power button.)

The special two_node option allows the cluster to have quorum even though
there's only one node remaining.  Everything should run normally on the
surviving node after you do the manual ack.  Using SAN fencing with the
brocade will eliminate this manual step.
