Hi experts, When I install and start slurm on Ubuntu as http://slurm.schedmd.com/quickstart_admin.html, I am confused about step 7:
NOTE: The *SlurmUser* must exist prior to starting Slurm and must exist on all nodes of the cluster. NOTE: The parent directories for Slurm's log files, process ID files, state save directories, etc. are not created by Slurm. They must be created and made writable by *SlurmUser* as needed prior to starting Slurm daemons. How to create slurmuser before creating those directories for slurm's log files..? When I create those directories as https://wiki.fysik.dtu.dk/niflheim/SLURM: mkdir /var/spool/slurmctld /var/log/slurm chown slurm: /var/spool/slurmctld /var/log/slurm chmod 755 /var/spool/slurmctld /var/log/slurm The command line shows: chown: invalid spec: "slurm:" Could any expert explain the meaning of step 7? Best Regards, Peixin
