I have my controller running (slurmctld and slrumdbd) and my controller and node host can ping each other by name so they resolve via /etc/hosts settings. When I try to start the slurmd.service it shows that it is active (running), but gives these errors:
Unable to register: Zero Bytes were transmitted or received The controller shows this from slurmctld.service: Munge decode failed: Invalid credential I copied the munge.key from controller to node (copying via an NFS shared directory required changing ownership and permissions and then changing them back). Apparently the node is communicating with the controller, but munge thinks I have a bad credential. Any idea how to troubleshoot this?
