[slurm-users] Re: what updates NODEADDR

IIRC, you need to ensure reverse lookup for DNS matches your nodename

Hi

I'm using dynamic nodes with "slurmd -Z" with slurm 23.11.1. Firstly I find that when you do "scontrol show node" it shows the NODEADDR as ip rather than the NODENAME. Because I'm playing around with running this in containers on docker swarm I find this ip can be wrong. I can force it with scontrol update however after a while something updates it to something else again. Does anybody know if this is done by slurmd or slurmctld or something else? How can I stop this from happening? How can I get the node to register with the hostname rather than ip?

cheers, Jakub
