Shall I worry about these ? in /var/lib/lxcfs?

LXCFS
1

Hello,

I am new to LXD. Very impressed. That’s a great project.

I installed it on archlinux. I followed the instruction to the letter (https://wiki.archlinux.org/index.php/LXD)

All is working ok (except --stateful snapshots, but that’s ok, I didn’t install CRIU).

The only weird thing I have is these ??? in cgroup:

$ ls -l /var/lib/lxcfs
ls: cannot access '/var/lib/lxcfs/cgroup': Input/output error
total 0
?????????? ? ?    ?    ?            ? cgroup
dr-xr-xr-x 2 root root 0 Apr  7 17:38 proc
dr-xr-xr-x 2 root root 0 Apr  7 17:38 sys

Is that normal? I can live with it, but am I missing something?

Thanks.
L.

That’s coming from our cgroup emulation which is only relevant on older kernels.
Don’t worry about it, only proc and sys is actively used and cgroup becomes valid if accessed by a process in a container that needs it.

Excellent. Thank you Stéphane !
