How can I avoid having to create a stonith device for each node in a cluster where the "port" (-n) values do not match the node names in RHEL 6 or 7 with pacemaker?
Issue
- Is there a way to not have to create a stonith device for every node just because the names listed in
-o listoutput don't match the node names? - How can I tell stonith to map nodenames to different names before passing them to a fence agent?
- My pacemaker nodes are virtualized guests, and my stonith device won't work because stonith passes the nodename as the
-n(port) value and it needs to pass the VM's name which is different
Environment
- Red Hat Enterprise Linux (RHEL) 6 or 7 with the High Availability Add on
Pacemaker- All nodes utilize a single shared stonith/fence device, but the node names do not match the values that must be passed to
-nor what is listed in-o listoutput to/from the stonith agent- This is often applicable in virtualized environments where the hostname is used as the node name, but the VM name on the host is different
