Hide
New OpenShift installs use Control Groups version 2 by default, also known as cgroup2 or cgroupsv2. This includes many bug fixes, performance improvements, and the possibility of integration with new features. cgroupsv1 are still used in upgraded clusters which have install born dates prior to 4.14. and can still be used by changing the CgroupMode of the Node Config object to be 'v1'.
