- Plesk for Linux
Disk space usage by the "Web" service is greater than overall disk usage of a domain, if the domain has web users.
This is a Plesk bug with ID PPPM-8374, which will be fixed in future product updates.
The "Web" service is being calculated in a manner that includes both web_users and httpdocs (but httpdocs already includes web_users).
# du -hs /var/www/vhosts/example.com/
# du -hs /var/www/vhosts/example.com/web_users/
# du -hs /var/www/vhosts/example.com/httpdocs/
14G (web users) + 14.5G (httpdocs + web users) ≈ 28.5G
Currently, there is no workaround.
