I am trying to start slurmd.service using below commands but it is not successful permanently. I will be grateful if you could help me to resolve this issue!
systemctl start slurmd
scontrol update nodename=fwb-lab-tesla1 state=idle
This is the status of slurmd.service
cat /usr/lib/systemd/system/slurmd.service
