error: cgroup namespace 'freezer' not mounted. aborting – Debian

Trying to run slurmd:

sudo systemctl start slurmd

I display the status of the daemon and an error is displayed on the screen:

>>sudo systemctl status slurmd

I don’t know how to fix it. I hope for your help. I use slurm version 18.08.05 and debian 10.

UPD.
I changed the ProctrackType value in slurm.config to proctrack/linuxproc:

ProctrackType=proctrack/linuxproc

All is work.

    Unlike the documentation (man cgroup.conf), the default value of the parameter CgroupMountpoint is not good.

    echo CgroupMountpoint=/sys/fs/cgroup >> /etc/slurm-llnl/cgroup.conf

    And you can reset the value of ProctrackType.

    In my case, this happened because I didn’t create and configure my cgroup.conf on the nodes running slurmd. Once this was added to the same directory as slurm.conf, it worked fine. CgroupMountpoint did not need to be defined as the default was sufficient.

    Same error in my cluster, my cgroup.conf wasn’t configured.

    A simple /etc/slurm/cgroup.conf with:

    CgroupAutomount=yes
ConstrainCores=no
ConstrainRAMSpace=no

    then:

    systemctl restart slurmd
