Hi Barbara,
This is a fresh install. I have installed slurm from source on Debian stretch
and now trying to set it up correctly. MariaDB is running for but I am confused
about the database configuration. I followed a tutorial (I can no longer find
it) that showed me how to create the database and give it to the slurm user on
mysql. Haven't really done anything further than that as running anything
return the same errors:

Did you upgrade SLURM or is it a fresh install?
Are there any associations set? For instance, did you create the cluster with
sacctmgr?sacctmgr add cluster <name>
Is mariadb/mysql server running, is slurmdbd running? Is it working? Try a
simple test, such as:sacctmgr show user -sIf it was an upgrade, did you try to
run the slurmdbd and slurmctld manuallly first:
slurmdbd -Dvvvvv
Then controller:
slurmctld -Dvvvvv
Which OS is that?Is there a firewall/selinux/ACLs?

Thank you Barbara,
Unfortunately, it does not seem to be a munge problem. Munge can successfully
authenticate with the nodes.
I have increased the verbosity level and restarted the slurmctld and now I am
getting more information about this:

The problem seems to somehow be related to slurmdbd? I am a bit lost at this
point, to be honest.

Hello,
does munge work?Try if decode works locally:munge -n | unmungeTry if decode
works remotely:munge -n | ssh <somehost_in_cluster> unmunge
It seems as munge keys do not match...
See comments inline..

I actually just managed to figure that one out.
The problem was that I had setup AccountingStoragePass=magic in the slurm.conf
file while after re-reading the documentation it seems this is only needed if I
have a different munge instance controlling the logins to the database, which I
don't. So commenting that line out seems to have worked however I am now
getting a different error:

My slurm.conf looks like this
# LOGGING AND ACCOUNTING
AccountingStorageHost=localhos t
AccountingStorageLoc=slurm_db
#AccountingStoragePass=magic
#AccountingStoragePort=
AccountingStorageType=accounti ng_storage/slurmdbd
AccountingStorageUser=slurm

ClusterName=research
JobCompType=jobcomp/none
JobAcctGatherFrequency=30

SlurmctldDebug=3
SlurmdDebug=3
You only need:AccountingStorageEnforce=assoc
iations,limits,qosAccountingStorageHost=<hostnam
e>AccountingStorageType=accounti ng_storage/slurmdbd
You can remove AccountingStorageLoc and AccountingStorageUser.
And the slurdbd.conf like this:
ArchiveEvents=yes
ArchiveJobs=yes
ArchiveResvs=yes
ArchiveSteps=no
#ArchiveTXN=no
#ArchiveUsage=no
# Authentication info
AuthType=auth/munge

SlurmUser=slurm

Thank you very much in advance.

Hi everyone,
I have set-up slurm to use slurm_db and all was working fine. However I had
to change the slurm.conf to play with user priority and upon restarting the
slurmctl is fails with the following messages below. It seems that somehow is
trying to use the mysql password as a munge socket? Any idea how to solve it?
