[Linux-cluster] post fail fencing

[Kaloyan Kovachev]

Hello,
 i would like to have one specific node to always fence any other failed node
and some nodes to never try to fence. For example in 4 or 5 nodes cluster:
Node1 is fencing any other failed, Node2 and Node3 will try fencing some time
later (in case the failed node is Node1) and Node4/Node5 should never try to
fence others

 What is the possible/recommended way to do this?
