[slurm-users] slurm-users Digest, Vol 11, Issue 45

[Alan Do-Omri]

I'm writing in response to the message below. I don't know how to reply in this mailing list. Do we just reply to everyone? 
And Eli, thank you for your help! Yes, the munge service is running. I am on Ubuntu 16.04.10.

Have you started the munge service? The order should be roughly, start
munge, start mysql/mariadb, start slurmdbd, start slurmctld, start
slurmd. You didn't mention which distribution you're using. On recent
debian versions the 3 slurm daemons have been split out independently
and you'll probably be better off installing them instead of the
slurm-llnl/wlm overall package since you only need the slurmdbd &
slurmctld on one or 2 nodes.
