Hi Guys, Thanks for your answers.
I would like not to patch the source code of Slurm, like Jacek does it, to make things easier. But I think, it is the way to go. When I try the solutions, Florian and Angelos suggested, slurm will still think that the nodes are "powered down", even if they not. Well, it is better that slurm only thinks that they are down, better as if they will power down while upgrading something. What we really need is some state like "MAINT", for maintenance, which will slurm tell, not to utilize the node but also don't power down the node.

Excerpt: hosts=$(scontrol show hostnames $1) for host in $hosts; do scontrol show node $host | tr ' ' '\n' | grep -q 'State=IDLE+POWER$' if [[ $? == 1 ]]; then echo "node $host NOT IDLE" >>$OUTFILE continue else echo "node $host IDLE" >>$OUTFILE fi ssh $host poweroff ... sleep 1 ... done Best, Florian ________________________________ From: slurm-users <slurm-users-boun...@lists.schedmd.com<mailto:slurm-users-boun...@lists.schedmd.com>> on behalf of Steininger, Herbert <herbert_steinin...@psych.mpg.de<mailto:herbert_steinin...@psych.mpg.de>> Sent: Monday, 24 August 2020 10:52 To: Slurm User Community List <slurm-users@lists.schedmd.com<mailto:slurm-users@lists.schedmd.com>> Subject: [External] [slurm-users] [slurm 20.02.3] don't suspend nodes in down state Hi, how can I prevent slurm, to suspend nodes, which I have set to down state for maintenance? I know about "SuspendExcNodes", but this doesn't seem the right way, to roll out the slurm.conf every time this changes. Is there a state that I can set so that the nodes doesn't get suspended? It happened a few times that I was doing some stuff on a server and after our idle time (1h) slurm decided to suspend the node.
