Does slurm require same version accross all nodes?

Question

I'me experimenting with a cluster set-up, where different nodes have either 19 or 20 version of slurm. The managing node has SLURM 20.

For some reason, nodes with SLURM 19 can't ping the manager (scontrol ping returns Slurmctld(primary) on node0 is DOWN).

I wonder if it is the incompatibility of SLURM 19/20 or did I messed-up anywhere else.

Thank you.

You can have different versions of the slurm components on your system, but there is an order:

slurmdbd >= slurmctld >= slurmd >= slurm-commands

And you should stay withing three releases (see https://slurm.schedmd.com/SLUG20/Field_Notes.pdf, slide 14).

As a side node: The major releases are the first four digits, based on year and month (yy.mm): 20.02 is the current major release 19.05 is the previous, and 20.11 is the next.

OK, that, probably, I messed-up somewhere else. – Araneus0390 Sep 23 '20 at 20:59
