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. -- Daniel Taylor VP Operations Vocal Laboratories, Inc dtaylor at vocalabs.com 612-235-5711
