Setting cpuset.memory_pressure_enabled in /etc/cgconfig.conf not working in RHEL 6

Solution Unverified - Updated -

Issue

  • Cannot set cpuset.memory_pressure_enabled = 1 via /etc/cgconfig.conf

    # service cgconfig start
Starting cgconfig service: Loading configuration file /etc/cgconfig.conf failed
Cgroup, requested group parameter does not exist
Failed to parse /etc/cgconfig.conf                         [FAILED]

  • The cgroups parameter  cpuset.memory_pressure_enabled cannot be set within a group.  It appears to only be applicable at the root of the cpuset controller, but we are unsure of how to set that in cgconfig.conf.

Environment
