rgmanager fails to start after "dlm_controld[xxx]: dlm_join_lockspace no fence domain" in logs in RHEL 6 MRG 2.x cluster

Solution Verified - Updated -

Issue

  • When starting a two node cluster, I can see that each node is online with clustat. However, rgmanager does not start. It fails with:
Jul 26 13:49:44 node1 kernel: dlm: Using TCP for communications
Jul 26 13:49:44 node1 dlm_controld[12252]: dlm_join_lockspace no fence domain
Jul 26 13:49:44 node1 kernel: dlm: rgmanager: group join failed -1 -1
  • rgmanagerfails to start and errors in logs should 'dlm_join_lockspace no fence domain'

Environment

  • Red Hat Enterprise Linux (RHEL) 6 with the High Availability Add On
  • Red Hat Enterprise MRG 2.x
    • Running on top of cman cluster
  • FENCE_JOIN="no" in /etc/sysconfig/cman
