[slurm-users] unable to start slurmd process.

[Riebs, Andy]

If you omitted the “-D” that I suggested, then the daemon would have detached and logged nothing on the screen. In this case, you can still go to the slurmd log (use “scontrol show config | grep -I log” if you’re not sure where the logs are stored).

I tried by executing the debug mode but there also it is not writing anything.

i waited for about 5-10 minutes

deda1x1452:/etc/sysconfig # /usr/sbin/slurmd -v -v

No output on terminal.

The OS is SLES12-SP4 . All firewall services are disabled.

The recent change is the local hostname earlier it was with local hostname node1,node2,etc but we have moved to dns based hostname which is deda

NodeName=node[1-12] NodeHostname=deda1x[1450-1461] NodeAddr=node[1-12] Sockets=2 CoresPerSocket=10 State=UNKNOWN
other than this it is fine but after that i have done several time slurmd process started on the node and it works fine but now i am seeing this issue today.

Navin.

Navin,

As you can see, systemd provides very little service-specific information. For slurm, you really need to go to the slurm logs to find out what happened.

Hint: A quick way to identify problems like this with slurmd and slurmctld is to run them with the “-Dvvv” option, causing them to log to your window, and usually causing the problem to become immediately obvious.

For example,

# /usr/local/slurm/sbin/slurmd -Dvvvv

Just it ^C when you’re done, if necessary. Of course, if it doesn’t fail when you run it this way, it’s time to look elsewhere.

Hi Team,

when i am trying to start the slurmd process i am getting the below error.

Slurm version is 17.11.8

The server and slurm is running from long time and we have not made any changes but today when i am starting it is giving this error message.
Any idea what could be wrong here.

Regards
Navin.
