2.6. Removing Control Groups

Use cgdelete to remove cgroups. It has similar syntax as cgcreate. Run the following command:
cgdelete subsystems:path
where:
  • subsystems is a comma‑separated list of subsystems.
  • path is the path to the cgroup relative to the root of the hierarchy.
For example:
~]# cgdelete cpu,net_cls:/test-subgroup
cgdelete can also recursively remove all subgroups with the option -r.
When you delete a cgroup, all its tasks move to its parent group.
