Hi, I need to take care of a 17.02 Slurm cluster (I'm preparing it for upgrades). I see that slurmdbd logs various "cluster not registered" messages at startup (DBD_CLUSTER_TRES,DBD_JOB_START,DBD_STEP_START), but I don't see a real problem. Accounting works. Do I have to worry? Can this be related to upper/lower case issues with ClusterName? For some reason ClusterName is all upper case in slurm.conf. According to docs (and my experience with Slurm 21.08) though, this should be OK. Thx for help Matthias
