This is a step in the right direction, but I don't think drbd will play nice
with PVFS.  The problem is PVFS has a client which is trying to talk to a server.
If that server runs drdb as primary, then it will keep a mirror copy on another
node.  The problem is, when the node fails, PVFS doesn't know how to find the
secondary.  This is functionality we are working to build into the next generation
of PVFS.
