[lxc-users] Limits kind of not working

[Pavol Cupka]

OK, thank you for your answer. So I can confirm CPU and memory limits
working. IO and network have to be tested on my part yet. What doesn't work
for me is disk "quota" I am using btrfs and I have set 20GB for the
container root, but was still able to allocate more the 90GB writing with
dd to a file inside the container. What am I doing wrong?

Thank you in advance
