question about cgroupv2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Sorry for disturbing.

I want to test how to use cgroup v2 on kernel 4.6.2.
And I have read https://www.kernel.org/doc/Documentation/cgroup-v2.txt
According to the above document, I added kernel parameter cgroup_no_v1=1.
But, system still automount the v1 cgroup.
Then, I executed:
# mount -t cgroup2 none /mnt

But, cgroup.controllers in /mnt is empty.

I'm not sure if I made something wrong or cgroup v2 is not supported on kernel 4.6.2?


Thanks
