Cgroup - no space left on device

Question

I have Debian 7 box and little issue:

mkdir /cgroups/test
echo 500 > /cgroups/test/cpu.shares
echo 3167 > /cgroups/test/tasks
bash: echo: write error: No space left on device

How can I fix it?

In fstab:

cgroup /cgroups cgroup defaults 0 0

I have installed: cgroup-bin, libcgroup1, libpam-cgroup

I'm not sure if this is a disk issue. Think this is more cgroup related. I might have some time to look into this tonight ... — justlovingIT, Mar 3, 2014 at 19:03

I have been able to reproduce and solve the issue doing :

/bin/echo 0 >/cgroups/test/cpuset.mems
/bin/echo 0 >/cgroups/test/cpuset.cpus

Seems that CPUs and Memory Nodes' list for the cpuset were created with empty values when the test folder was created.

Hope it will work for you also.

Hello! Has a bug report been filed for this? I didn't see one with a cursory search. This one needs to go upstream. bugzilla.kernel.org Thanks. At the very least, we should get a warning in the kernel logs.
