Is there a way to have a RHEL 6 node in a two-node cluster panic or reboot itself when there's a problem instead of needing power or storage based fencing?

Solution In Progress - Updated -


  • Can I configure cluster nodes to use panics or reboots of some kind as a fence mechanism?
  • I don't have access to power fencing or shared storage. How can I configure the cluster nodes to fence themselves?


  • Red Hat Enterprise Linux (RHEL) 6 with the High Availability Add On
  • cman or cman/pacemaker cluster
  • Two-node cluster
  • No direct access to shared SCSI storage or power fencing mechanisms
