I've just set up slurm where one physical machine will be the only system in the cluster (so far). This is on Ubuntu 18.04.

I have slurmdbd running, but when I attempt to start up slurmd and slurmctld this times out. Why?

I'm issuing the following commands:

systemctl start slurmctld
systemctl start slurmd

I've also tried:

systemctl start slurmctld slurmd

and:

systemctl start slurmd slurmctld

This fails with the following, for slurmctld:

systemd[1]: slurmd.service: Can't open PID file /var/run/slurm-llnl/slurm-llnl/slurmd.pid (yet?) after start: No such file or directory
systemd[1]: slurmctld.service: Start operation timed out. Terminating.
systemd[1]: slurmctld.service: Failed with result 'timeout'.
systemd[1]: Failed to start Slurm controller daemon.

And for slurmd:

systemd[1]: slurmd.service: Start operation timed out. Terminating.
systemd[1]: slurmd.service: Failed with result 'timeout'.
systemd[1]: Failed to start Slurm node daemon.

However, when I start these manually (using two terminals) by issuing:

slurmctld -Dvvv
slurmd -Dvvv

Everything appears to work.

Why is this? How am I supposed to start slurm?

These are the service files (which should be standard, I didn't touch them except for adding verbose arguments, but then removing them again later):
