Thank you Dave, although /var/log/messages says only the same as I mentioned above (after cluster startup and on mount command): Feb 18 16:47:00 share2 kernel: GFS: Trying to join cluster "lock_dlm", "cluster1:eva" Feb 18 16:47:00 share2 kernel: lock_dlm: fence domain not found; check fenced Feb 18 16:47:00 share2 kernel: GFS: can't mount proto = lock_dlm, table = cluster1:eva, hostdata = No more helpful info. I'll try to cycle both nodes together and see if it helps fencing. BTW: I used "fence_tool join" with "-t 120" option before. Looks like it's been deprecated in recent GFS versions?
