Joe references Disk Quota Monitoring in the 3.65 release announcement, and that sounds useful, but I can’t find it in my 3.65 Reseller account, even Ctrl-F searching. There are also references to “Limits & Validation”, a menu option, but this doesn’t exist in my install, either???
Thanks for asking. All of my issues are now closed.
The answer to this one is that it is a root privilege only.
The answer to the quota issue was my own unfamiliarity with the fact that there are two different quotas for a virtual domain, and I had only increased one of them.
