Question: The disk usage report for Reseller and WebAdmin is not correct. It displays Space Utilized: 0.00 KB. What does this mean?
The Disk Usage reports are generated by Hosting Controller Quota service. The disk space calculation is a processor intensive job therefore it is not desirable to calculate the disk usage all the time. This service runs in a specific duration to calculate the disk usage for each account. At the same time disk usage reports are generated and e-mailed to customers if e-mail alerts are set under Panel Configuration :: Configure Services :: Disk Usage Settings.
After creating a new account, wait for some time so that DiskQuota service runs and calculates the disk usage. After that when you view the Disk Usage Report, you will see the correct usage.
