    Hi all<br>
    <br>
    Seems there still are some issues with the autofs -
    job_container/tmpfs functionality in Slurm 23.02.<br>
    If the required directories aren't mounted on the allocated node(s)
    before jobstart, we get:<br>
    <br>
    <font size="-1" face="Courier New, Courier, monospace">slurmstepd:
      error: couldn't chdir to `/users/lutest': No such file or
      directory: going to /tmp instead<br>
      slurmstepd: error: couldn't chdir to `/users/lutest': No such file
      or directory: going to /tmp instead</font><br>
    <br>
    An easy workaround however, is to include this line in the slurm
    prolog on the slurmd -nodes:<br>
    <font size="-1" face="Courier New, Courier, monospace"><br>
      /usr/bin/su - $SLURM_JOB_USER -c /usr/bin/true</font><br>
    <br>
    -but there might exist a better way to solve the problem?<br>
    <br>
    Best<br>
    Niels Carl<br>

              Hi Jason,<br>
              <br>
              IMHO, the job_container/tmpfs is not working well in Slurm
              22.05, but<br>
              there may be some significant improvements included in
              23.02 (announced<br>
              yesterday).  I've documented our experiences in the Wiki

              This page contains links to bug reports against the

              We're using the auto_tmpdir SPANK plugin with great
