Trimmed for space.

You could do as Tom Pfaff suggests, but given the odds of data 
corruption carrying forward I'd do the following:
Shut down gluster on the damaged system.
Unmount the damaged filesystem.
Reformat the damaged filesystem as new (throwing away any potential 
corruption that might not get caught on rebuild)
Mount the new filesystem at the original mount point
Restart gluster

In the event of corruption due to hardware failure you'd be doing this 
on replacement hardware.
The key is you have to have a functional filesystem for gluster to work 
with.
