I guess that the question that comes to mind is.. Is it a really big deal if
the slurmctld process is down whilst the slurmdbd is being upgraded?
I tend to always stop slurmctld before upgrading slurmdbd, and have
never noticed any problems with that.
That's actually a stated recommendation, read the detailed documentation
in https://slurm.schedmd.com/quickstart_admin.html#upgrade
It's OK to stop slurmctld for some minutes, but you may want to increase
some timeouts in slurm.conf. See also my Wiki page
