I don't know very much but what I understand from fencing is forcefully disabling a node that is not reachable by cluster to prevent this dead node accidently (maybe the node wasn't dead and will try to write something to shared storage which can cause catastrophic damage if GFS is not used) write something to file system. It does this using power switches or other methods such as IPMI or ILO .(I heard there was a new module for fencing that uses vmware ) Thus I think this fencing conecpt is the same as STONITH in linux-ha.org which means Shoot The Other Node In The Head(Heart).... If I am mistaken someone please correct me. > I'm a bit unclear on the concept of fencing.
