lmctfy init error

[Nipun Sehrawat]

Hello,

I built the latest release of lmctfy (0.5) and tried creating a cgroup hierarchy using the following config:

cgroup_mount:{

  mount_path:'/sys/fs/cgroup/freezer'

  hierarchy:CGROUP_FREEZER

}

cgroup_mount:{

  mount_path:'/sys/fs/cgroup/cpu'

  hierarchy:CGROUP_CPU

  hierarchy:CGROUP_CPUACCT

}

cgroup_mount:{

  mount_path:'/sys/fs/cgroup/cpuset'

  hierarchy:CGROUP_CPUSET

}

cgroup_mount:{

  mount_path:'/sys/fs/cgroup/memory'

  hierarchy:CGROUP_MEMORY

}

The command I run to initialize cgroups is (the machine doesn't have any cgroups mounted already):

sudo ./lmctfy init -c ../../../cgroup_config/config.ascii 

It fails with the following message:

Command exited with error message: 5: lmctfy requires a canonical tasks cgroup hierarchy, none were found

try using --stderrthreshold to get more info

Reading through the source code of lmctfy_impl.cc, it seems that freezer cgroup is expected to be mounted as the canonical cgroup task tracking hierarchy. Could someone point out if I am missing some steps?

Thanks,

Nipun
