Description Johnny Liu 2014-07-15 08:37:55 UTC 
Description of problem:
When user remove net_cls from OPENSHIFT_CGROUP_SUBSYSTEMS, "oo-cgroup-enable -a" does not work.
# oo-cgroup-enable -a
undefined method `[]=' for nil:NilClass

Version-Release number of selected component (if applicable):
rubygem-openshift-origin-node-1.23.9.11-1.el6op.noarch

How reproducible:
Always

Steps to Reproduce:
1.Create an app.
2.On node, run "oo-cgroup-disable -a"
3.Set OPENSHIFT_CGROUP_SUBSYSTEMS in /etc/openshift/node.conf, note that not include net_cls
OPENSHIFT_CGROUP_SUBSYSTEMS=cpu,cpuacct,memory,freezer,blkio
4.On node, run "oo-cgroup-enable -a"


Actual results:
# oo-cgroup-enable -a
undefined method `[]=' for nil:NilClass

Expected results:
should be no error, and no net_cls cgroup subsystem is defined.

Additional info:
If remove other CGROUP items, e.g: memory, it is working well.

OpenShift Enterprise v2 has officially reached EoL.  This product is no longer supported and bugs will be closed.

Please look into the replacement enterprise-grade container option, OpenShift Container Platform v3.  https://www.openshift.com/container-platform/
