How do you 'manually create a directory'? That would be when the
ownership of root would be occurring. After creating it, you can
chown/chmod it as well.

Dear slurm community,
I run slurm 21.08.1 under Rocky Linux 8.5 on my small HPC cluster and
am trying to configure job_container/tmpfs to manage the temporary
directories.
I have a shared nfs drive "/home" and a local "/scratch" (with
permissions 1777) on each node.
For each submitted job I manually create a directory with the
"JOB_ID.$USER" in the local "/scratch" which is where all the temp
files for the job will be generated. Now, I would like to do these
automatically (especially to remove the directory when the job
finishes or is canceled):
I added the following parameters in my /etc/slurm.conf:
JobContainerType=job_container/tmpfs
PrologFlags=contain
So, I have created the "job_container.conf" in the directory "/etc/slurm"
with the following configuration:
AutoBasePath=false
BasePath=/scratch
Then, I replicated the changes to all nodes and restarted the slurm
daemons.
Finally, when I launch the job a directory with the "JOB_ID" is
created in the local "/scratch" of the compute node. The only problem
is that the owner of the directory is "root" and the user who
submitted the job doesn’t have read and write permissions to that
directory (other users do not either).
I would like that:
1) The name of the automatically created directory will be: "JOB_ID.$USER"
2) The owner of the directory will be the user who submitted the job,
not "root".
Please, could someone help me?
Thanks a lot.
Best regards,
Alain
