[slurm-users] systemctl enable slurmd.service Failed to execute operation: No such file or directory

Thu Jan 27 15:23:11 UTC 2022

The missing file error has nothing to do with slurm.  The systemctl command is part of the systems service management.

The error message indicates that you haven’t copied the slurmd.service file on your compute node to /etc/systemd/system or /usr/lib/systemd/system.  /etc/systemd/system is usually used when a user adds a new service to a machine.

Depending on your version of Linux you may also need to do a systemctl daemon-reload to activate the slurmd.service within system.

Once slurmd.service is copied over, the systemctld command should work just fine.

Remember:
                slurmd.service     -  Only on compute nodes
                slurmctld.service – Only on your cluster management node
              slurmdbd.service – Only on your cluster management node

Hello everyone,

I am installing slurm on Centos 7 following tutorial: https://www.slothparadise.com/how-to-install-slurm-on-centos-7-cluster/

I am at the step where we start slurm but it gives me the following error:

[root at exxact slurm-21.08.5]# systemctl enable slurmd.service
Failed to execute operation: No such file or directory

I have run the command to check if slurm is configured properly

[root at exxact slurm-21.08.5]# slurmd -C
NodeName=exxact CPUs=12 Boards=1 SocketsPerBoard=1 CoresPerSocket=6 ThreadsPerCore=2 RealMemory=31889
UpTime=19-16:06:00

I am new to this and unable to understand the problem. Kindly help me resolve this.
