fence_xvm times out or hangs for long periods of time in a RHEL 5, 6, or 7 High Availability cluster of VMs running on a RHEL 6 or 7 host using fence-virtd-multicast
Issue
- I am trying to get
fence_xvmto work on mylibvirtVMs, and the request just times out.
# fence_xvm -a 226.18.19.20 -k /etc/cluster/fence_virtd.key -o list
Timed out waiting for response
Operation failed
- My VM cluster nodes that use
fence_xvmcan't fence each other. - How can I troubleshoot
fence_xvmnot returning any results or fencing a node?
Environment
