clusvcadm command hangs, clustat does not show service states, or other rgmanager-based operations block on a RHEL High Availability cluster node

Solution Verified - Updated -


  • clusvcadm -d, clusvcadm -e, or other clusvcadm operations hang and never return
  • When running the clustat command we do not see any services, and it lists the following error message:
Service states unavailable: Temporary failure; try again
  • clurgmgrd resgroup_thread_main stuck waiting on dlm lock for service, causing other operations (such as disabling services) to hang
  • I can't enable or disable services. The operation just hangs forever.
  • rgmanager is hung.
  • clustat or rgmanager hangs and doesn't provide service lists
  • Nodes can talk to each other, both can see online but while we fire clustat, services are not listing.
  • clustat reports "Timed out waiting for a response from Resource Group Manager"
  • When I start rgmanager, there are no errors but it never seems to finish starting and doesn't log anything useful, and doesn't start services or initialize resources.
  • You see this in clustat:
Timed out waiting for a response from Resource Group Manager
  • There are four services running in this cluster, and we're trying to freeze each one with clusvcadm -Z. All services except one get frozen, the other one just sits there forever without returning.
  • clusvcamd is hanging and not showing any detail while disabling the service


  • Red Hat Enterprise Linux (RHEL) 5 or 6 with the High Availability Add On
  • rgmanager
