Description steve 2011-03-03 20:50:45 UTC
Section 2.1.1 contains

********begin doc sample ****************

mount {
    cpuset = /cgroup/cpuset;
}

creates a hierarchy for the cpuset subsystem, the equivalent of the shell commands:

        mkdir /cgroup/cpuset
        mount -t cgroup -o cpuset cpuset /cgroup/cpuset

Group entries create control groups and set subsystem parameters. For example: 

group daemons/sql {
    perm {
        task {
            uid = root;
            gid = sqladmin;
        } admin {
            uid = root;
            gid = root;
        }
    } cpuset {
        cpuset.cpus = 0-3;
    }
}

creates a control group for sql daemons, with permissions for users in the sqladmin group to add tasks to the control group and the root user to modify subsystem parameters. When combined with the example of the mount entry above, the equivalent shell commands are:

mkdir -p /cgroup/cpu/daemons/sql
chown root:root /cgroup/cpu/daemons/sql/*
chown root:sqladmin /cgroup/cpu/daemons/sql/tasks
echo 0-3 > /cgroup/cpu/daemons/sql/cpuset.cpus

*********end doc sample **************


   The 4 shell commands are incorrect for the example above. They should
be

mkdir -p /cgroup/cpuset/daemons/sql
chown root:root /cgroup/cpuset/daemons/sql/*
chown root:sqladmin /cgroup/cpuset/daemons/sql/tasks
echo 0-3 > /cgroup/cpuset/daemons/sql/cpuset.cpus

  ie replace directory "cpu" with "cpuset". I think.
