[slurm-users] Slurm Upgrade from 17.02

[Ricardo Gregorio]

Thank you Ole/Chris/Marcus. Your input was much appreciated....

Ole, I was(am) basing my upgrade plan using the documentation found on the link you had sent me. In fact your wiki is always my first stop when learning/tshooting SLURM issues, even before SLURM docs pages. Excellent work, well done.

Regards,
Ricardo Gregorio

You should be able to upgrade 2 Slurm major versions in one step.  The
18.08 version is just about to become unsupported since 20.02 will be released shortly.  We use 19.05.5.

I have collected a number of upgrading details in my Slurm Wiki page:

You really, really want to perform a dry-run Slurm database upgrade on a test machine before doing the real upgrade!  See

We use the default MariaDB 5.5 in CentOS 7.7.  Upgrading to MariaDB 10 seems to have quite a number of unresolved installation issues, so I would skip that for now.  Se s

Slurm 19.05 works great for us.  We're happy with our SchedMD support contract.
