Hello, In production You need automatic fencing, because when one node goes down, Your GFS filesystem will be freezed(no ro/rw operations permited) until You perform manual fencing. You could try to use new fence_scsi agent, but You need to check if Your storage support Persistent Reservations (SPC-2 or greater).
