Some cluster components cannot start properly with redundant ring configured in RHEL 6

Solution Unverified - Updated -

Issue

  • Why was a node, after having its cluster services started and join the cluster domain successfully, not able to have the DLM be configured when using a redundant ring configuration?

  • fenced, rgmanager, GFS2, clvmd, and/or rgmanager do not start or function properly when using dlm with SCTP
