All fencing daemons running in the cluster form a group called the "fence domain". Any member of the fence domain that fails is fenced by a remaining domain member. The actual fencing does not occur unless the cluster has quorum so if a node failure causes the loss of quorum, the failed node will not be fenced until quorum has been regained. If a failed domain member (due to be fenced) rejoins the cluster prior to the actual fencing operation is carried out, the fencing operation is bypassed.
