do you mean STONITH will itself determine whether there is need of fencing or not and will get executed accordingly.
i am completly new to STONITH and configuring it first time. i am doing following. could you please verify it. i want to configure stonith external riloe. as for configuring riloe i need to give ilo_hostname ,ilo_password etc which is specific to each host. i have two nodes and that's why i am adding two premitive stoniths resource(stonith-node1 and stonith-node2) . stonith-node1 will keep all riloe parameters details of node1 and stonith-node2 will keep all riloe parameters detail of node2. now i will add resource constraint to make stonith-node1 to allways run on node1 . and same like this for stonith-node2. Please let me know your view on above steps. one thing more , does a node need quorum to fence another node. as in my case , i have only two nodes so will a node will be able to stonith other in split brain situation . As in split brain situation both nodes will loose quorum . Thanks a lot for your help.
