rgmanager segfaults with central_processing enabled in RHEL 6

Solution Verified - Updated -

Issue

  • Managing a service with clusvcadm while central_processing is enabled leads to an rgmanager segfault
  • When building a VM resource on a different node than the current RG-Master, the final clusvcadm -d and subsequent clusvcadm -e of the new ressource segfaults the rgmanager, leading to an immediate fencing of the node. When running the same procedure on the current RG-Manager, everything works as expected.
  • A cluster node crashes and gets fenced while enabling, disabling, relocating, restarting, or migrating a service withi clusvcadm and central_processing enabled.

Environment

  • Red Hat Enterprise Linux (RHEL) 6 with the High Availability Add-On
  • rgmanager prior to release 3.0.12.1-12.el6
  • <rm central_processing="1"> in /etc/cluster/cluster.conf
