You're attempting to start the slurmd - which isn't required on this machine, as you say. Disable it. Keep slurmctld enabled (and declared in the config). > therefore, my *question:* > > What is the best practice for excluding the master node from work?

These states are slurmd states, and therefor meaningless for a machine that doesn't have a running slurmd. (It's the nodes that are defined in the config that are supposed to be able to run slurmd.) > So is *DRAINED* the correct setting in such a case? Since this only applies to a node that has been defined in the config, and you (correctly) didn't do so, there's no need (and no means) to "drain" it.
