Hi,
I encountered an issue a while back when Slurm would expect a cgroups v1
hierarchy, but Debian 11 had switched to cgroups v2.
I don't know whether this has been tackled in Slurm since then, but I
worked around it by adding "systemd.unified_cgroup_hierarchy=0" to the
kernel command line to enable hybrid cgroup mode.

https://unix.stackexchange.com/questions/480747/how-to-find-out-if-systemd-uses-legacy-hybrid-or-unified-mode-cgroupsv1-vs-cgr
to find out which mode is active on your system.
Best,
Christoph

Hi,
I'm trying to use cgroups in my slurm config on Debian 11 (installed through
debian apt repo), but slurmd won't start, I've attached the relevant
slurmd.log
as well as slurm.conf and cgroup.conf files
The error seems to be unable to get parameter 'tasks' for
'/sys/fs/cgroup/cpuset/'
I've added the `cgroup_enable=memory swapaccount=1` to the cmdline but that
doesn't help
I've seen people having those kind of problems, but no one seem to be
able to solve it and keep the cgroupsThanks a lot
Arthur
