Hi,

Normally updating slutm.conf across cluster & scontrol reconfigure should work.

Subject: [slurm-users] Use of scontrol update PartitionName
 
Hi,

To adapt to changing users need, we change which nodes are in what partitions. We use the command:

scontrol update PartitionName=partition01 Nodes=nd[001-200]

and modify slurm.conf at the same time to match.

But when I try to just modify slurm.conf and restart the process "slurmctld". The command "scontrol show PartitionName=partition01" still show the old list of nodes. Even after I reboot the slurmctld server completely. I don't know where the cached version of the list is or how it keeps it. Is there a some slurm.conf configuration that dictated that behavior?

Any hints?

Richard
