Well, that's why GFS stops working. You need to work out why it's 
failing. I've never used that particular fencing device, so I can't help 
you, but checking through the documentation for the xvm fencing agent 
might be a good start. If that doesn't tell you what you need, try 
asking on the redhat clustering (RHCE) mailing list. That would be the 
right place to ask, rather than here as it has nothing at all to do with 
DRBD.
