I've been asked to upgrade our slurm installation. I have a slurm 2.3.4
on a Debian 7.0 wheezy cluster (1 master + 8 nodes). I've not installed
it so I'm a bit confused about how to do this and how to proceed without
destroying anything.
I was thinking to upgrade at least to Jessie (Debian 8) but what about
Slurm? I've read carefully the upgrading section
(https://slurm.schedmd.com/quickstart_admin.html) of the doc, reading
that the upgrade must be done incrementally and not jumping from 2.3.4
to 17, for example.
Yes, you may jump max 2 versions per upgrade.
Quoting https://slurm.schedmd.com/quickstart_admin.html#upgrade
Slurm daemons will support RPCs and state files from the two previous minor releases (e.g. a version 16.05.x SlurmDBD will support slurmctld daemons and commands with a version of 16.05.x, 15.08.x or 14.11.x).
Stil is not clear to me precisely how to do this. How would you proceed
if asked to upgrade a cluster you just don't know nothing about? What
would you check? What version of o.s. and slurm would you choose? What
would you backup? And how would you proceed?
Any info is gold! Thank you
My 2 cents of information:
My Slurm Wiki explains how to upgrade Slurm on CentOS 7:
https://wiki.fysik.dtu.dk/niflheim/Slurm_installation#upgrading-slurm
Probably the general method is the same for Debian.
