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

Solution

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.

Provide the mount options for your cgroups mount.

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 ...
