OpenShift Enterprise 1.2 Deployment Guide refers to /cgroup/all which does not exist

Issue

  • In the OpenShift Enterprise 1.2 Deployment guide, under section 6.7.2. Configuring cgroups, it asks to verify the cgroups configuration and makes references to the /cgroup/all directory. There is also no mention of /cgroup/all in /etc/cgconfig.conf. Is this a documentation bug?

  • Here is the snip:

Verifying the cgroups Configuration
When cgroups have been configured correctly you should see the following:

    the /etc/cgconfig.conf file exists with SELinux label system_u:object_r:cgconfig_etc_t:s0.
    the /etc/cgconfig.conf file mounts cpu, cpuacct, memory, and net_cls on the /cgroup/all directory.
    the /cgroup directory exists, with SELinux label system_u:object_r:cgroup_t:s0.
    the command service cgconfig status returns "Running".
    the /cgroup/all directory exists and contains subsystem files for cpu, cpuacct, memory, and net_cls. 

When the cgred service is running correctly you should see the following:

    the /etc/cgrules.conf file exists with SELinux label system_u:object_r:cgrules_etc_t:s0.
    the service cgred status command returns "Running". 

When the openshift-cgroups pseudo-service has been run successfully, the /cgroup/all/openshift directory should exist, and contain subsystem files for cpu, cpuacct, memory, freezer, and net_cls. 

The contents of /opt/rh/ruby193/root/usr/share/gems/doc/openshift-origin-node-*/cgconfig.conf contains:

mount {
        cpuset  = /cgroup/cpuset;
        cpu     = /cgroup/cpu;
        cpuacct = /cgroup/cpuacct;
        memory  = /cgroup/memory;
        devices = /cgroup/devices;
        freezer = /cgroup/freezer;
        net_cls = /cgroup/net_cls;
        blkio   = /cgroup/blkio;
}
