Precursor: The commands are a default of the root ~/.bashrc file. The server must be rebooted in order for these commands to sticky and become active.
Some quick Q's
- Can you confirm that you have done the recommended reboot after install?
- Can you confirm that this is a dedicated server and not a VPS running OpenVZ?
- Is this machine from either OVH or it's reseller SYS?
Something interesting and a bit more detail
quotaoff is something built into the dependency tree that was installed with QuickBox.. it is not a QuickBox command per se.
I am curious however as I see
showspace are working. Do me this favor and ...
Let me know what all shows there.
Additionally, what lives in your
/etc/fstab? It may be possible (for some very odd reason) the quota package did not get installed. I will sample this against another Debian 8 install.
