Common issues: Slurm configuration errors

Possible error messages

• Unable to execute command /usr/bin/systemctl --system start slurmd

Resolution

Because Slurm requires all of the nodes of a cluster to be defined in slurm.conf, CycleCloud pre-creates all of the VMs inside of CycleCloud when you first start the scheduler node. These VMs remain unallocated in Azure until a job requests them, but sometimes insufficient quota or incorrect autoscale limits cause installation issues.

• Make sure your subscription has enough quota for the selected VM type and that the autoscale limits are below the quota amount. You might have to select a different VM type or adjust your autoscale limits.
• Check /var/log/slurmctld/slurm.log for any errors related to starting the scheduler.
