plesk ubuntu disk usage size incorrect

plesk ubuntu says the client is 36.8gb when checking the file size in terminal with "du -hs" says the domain is only using 8gb.

root@blue:/var/www/vhosts/files.millimetercreative.com# du -hs

8.4G .

this domain has no mail accounts and @11mb in logs...

i tried restarting plesk ubuntu with

root@blue:/var/www/vhosts/files.millimetercreative.com# /etc/init.d/psa restart

ii just tried psa stopall and start... and that didn't take care of the error...

apparently the disk usage is created by the daily maintenance script.

Run daily maintenance script: /opt/psa/bin/sw-engine-pleskrun /opt/psa/admin/plib/DailyMaintainance/script.php

that script kept spinning. i found the solution on parallels forums

/usr/local/psa/admin/sbin/statistics --calculate-one --domain-name=

^^^ this is still spinning as i write.

I found this << solution >> from another thread:
"
Go to Settings => Settings of server statistics => System Preferences

Under Include in the disk space usage calculation, uncheck domain backup files[/QUOTE]
