There are two things that take up a substantial amount of space on a WHM server if not carefully managed:
- Files contained in account trash folders
- Incomplete / temporary cPanel uploads
To remove all files contained in account trash folders login to your WHM server via SSH and issue the following commands:
rm -rfv /home/*/.trash/*
To remove all incomplete / temporary cPanel uploads issue the following command:
rm -fv /home/*/tmp/Cpanel_*
A command I found particularly useful in find large files on the server is the following:
find /home -type f -size +200000k -exec ls -lh {} ; | awk '{ print $9 ": " $5 }'
This command finds files >= 200 Mb
