About cgroups

OAR does not use Linux CGroups v2. The operating system on nodes must enable CGroups v1 in order for OAR to function with its usual advanced features. You can enable the Linux CGroups v1 (if disabled by default in your distro) by adding to your kernel command line on all machines where the oar-node service runs:

systemd.unified_cgroup_hierarchy=false systemd.legacy_systemd_cgroup_controller=true

(see /boot/grub/grub.conf, or /etc/default/grub on all nodes)
