We have migrated domains from cPanel to cPanel using the transfer tool and after migration, the Quota showing unlimited and Disk used is showing 0 MB. Not sure why it is like this.
Please ensure that it is running as a privileged container. LXC when running as unprivileged will have all sorts of issues due to things like /dev/null, /dev/random, /dev/urandom, and /prox being owned by nobody instead of root. Specifically, if /proc/mounts cannot be read, quotas will not function.
Installed cPanel in an LXC container, services won't start and getting a lot of errors
