Hi,
I am using Cloudmin Pro. I have created 2 OpenVZ containers and set up the host for KVM (but no VMs yet). My containers are running into quota limits. I have allocated 200GBs of disk space to the CTs each, but if I the disk usage of a CT reaches the 40GB limit, everything, even the Webmin/Virtualmin running on in the container is crying for quota limit. If I try to use the disk space of the container from the host (as root user), I run into the same quota limit. (other directories of the host are okay).
As far as I know, all of the quotas are switched off (no quota support) on the host, and in the CTs as well. quota -g root and quota -u root gives empty string on both the host and the container.
Webmin/System/Disk Quotas of the CT shows "No local filesystems can support quotas." mount | grep quota gives empty string ont the host and the CTs.
What part of Cloudmin is setting up a quota for the CTs?

Howdy -- hmm, what error is it that you're seeing exactly, and where is it that you're seeing it?

I get a "Disk quota exceeded" for any write attempts as a root inside the container. I get the same error message, if I try to write to the /vz/private/10000/ directory as root on the host. I get "Failed to open /etc/webmin/apache/site for writing : Disk quota exceeded" in Webmin/Virtualmin of the CT.
"df" at the CT

Yeah that's definitely very odd if quotas aren't enabled!
What is the output of the command "mount" on the host?
Also, what is the output of the command "repquota -v /" on the host?

Apologies for the delay here -- you're likely seeing some form of OpenVZ resource issue, it's probably not a filesystem quota issue.
Unfortunately, I don't know what OpenVZ resource limit that might be, though Jamie would know -- however, he is traveling at the moment.
The one thing I'd check though, is to review your Cloudmin settings for that container, and just verify that you don't see any resource related options that would restrict how much disk space the container would be able to use.
