<p>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.</p>

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