The nodes are being removed as they aren't resolving in DNS anymore; are you using a dynamic system where only active hosts' names resolve?

Subject: [slurm-users] slurmctld removing offline nodes

We noticed that the slurm controller will remove nodes that it cannot reach.
How can this be disabled?
We would like to see the nodes marked down/drain instead of the controller removing the nodes from sinfo.
