[slurm-users] Running slurmd without enabling jobs on a node

[Steve Brasier]

Hi all,

For a cluster in configless mode there appear to be two ways of having a login-only node (i.e. not running slurmctld) - either 1) setting DNS records or 2) "... consider running slurmd on the machine so it can manage the configuration files, but not allowing it to run jobs." [A]

What's the best way of achieving option 2)? Ideally I don't want the login node(s) which are running slurmd even showing up in e.g sinfo.

Hi;

I don't know the best way, but if you did not put a loginnode's name
into a partition, the sinfo will not show this node and any job will not
run on this node, just because of a node have a running slurmd.

Hi Steve,

I put my login node into a hidden & inactive partition.

Thanks all, turns out those nodes do need to be defined in the config using NodeName, but then as Ahmet M says just don't include them in a partition.
