Is it possible to configure a RHEL cluster such that it will function with only 1 node up?

Solution Verified - Updated -

Issue

  • I want to configure cluster so that only 1 node needs to be up for cluster to function.
  • Can a last man standing configuration be used in a RHEL High Availability cluster?
  • How can I configure qdiskd to provide votes such that one node can function by itself?

Environment

  • Red Hat Cluster Suite 4+
  • Red Hat Enterprise Linux (RHEL) 5 or 6 with the High Availability Add On
    • cman for cluster membership and quorum
    • NOTE: See this solution for more information on achieving similar goals in RHEL 7 with pacemaker and votequorum
  • 3 or more nodes in the cluster
