It could be systemd doing that.  Since slurmdbd is being started with -D, I would verify that slurmdbd.service has Type=simple and not Type=forking.   The systemctl status output later in the thread shows systemd starting slurmdbd with -D.

If that's the slurmdbd package from Ubuntu you might find that it's got the opposite config to what you expect.

This email was sent to you by someone outside the University.

You should only click on links or attachments if you are certain that the email is genuine and the content is safe.

That SIGTERM message means something is telling slurmdbd to quit.

Check your cron jobs, maintenance scripts, etc. Slurmdbd is being told to shutdown. If you are running in the foreground, a ^C does that. If you run a kill or killall on it, you will get that same message.

Thank you Ahmet,

I dont have a firewall active.

And because slurmdbd cannot connect to the database I am not able to getting it to be activated through systemctl I will share the output for slurmdbd -D -vvv shortly but overall it is always saying trying to connect to the db and then retries a couple of times and crashes

Hi;

Did you check can you connect db with your conf parameters from head-node:

mysql --user=slurm --password=slurmdbpass  slurm_acct_db

Also, check and stop firewall and selinux, if they are running.

Last, you can stop slurmdbd, then run run terminal with:

slurmdbd -D -vvv

Hi everyone

I am trying to get slurmdbd to run on my local home server but I am really struggling.

Note : am a novice slurm user

my slurmdbd always times out even though all the details in the conf file are correct

but everytime I try to start slurmdbd.service it crashes and I have that log that I shared with you

I use these versions

slurmdbd -V

slurm-wlm 19.05.5

mysql Ver 15.1 Distrib 10.3.39-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

Everything else Is working properly except I cannot get slurmdbd to work and at this point I exhausted all my possible trials :) looking for some expert insights :)

Any idea what I am doing wrong here ? Also I didn't compile any slurm package. I used the binary from apt repos

Any help will be appreciated

Cheers
