Otherwise, the commands may not be able to communicate with the daemons if there's a protocol change. We were running the Slurm daemons in a container and ran into a problem where the commands could no longer communicate with the daemons when the version of Slurm on the host was updated, but the container was still running an older version of the daemons.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Rigoberto</div><div><br></div>

<p class="yiv0249574192MsoNormal">Just wondering if any sites are running containerized Slurmctld and Slurmdbd in production?</p>

<p class="yiv0249574192MsoNormal">We are in the process of planning migrating from a single host running slurmctld, slurmdbd, and MySQL (and other HPC services) to separate OpenStack VMs. Our site averages less than 1000’s running / pending jobs at any given time. Like
many HPC sites, our jobs are a mix of long running, large arrays, very short…</p>
