[Linux-cluster] Clusterng with GFS

[Jayson Vantuyl]

You should not be unmounting the GFS anywhere.  GFS should be mounted  
everywhere.  With proper fencing (which is a MUST, no avoiding it)  
GFS can recover from losing a node with no downtime.  Then you just  
need to have the appropriate daemons and cleanup scripts running  
(usually from rgmanager).

If you want to failover a normal volume (another way to do this),  
just use XFS, reiserfs, or ext3.
