If your /var/ partition is full, and you’re having problems tracking down things you can safely delete, something you can do is move the /var/log to a different partition like /home.
To do this, you will need to modify a file however otherwise, customers auto responders will break. I’m not sure why this happens, however cPanel support themselves have given me this fix.
First, mv /var/log to your new location. In this example, we will move it to /home
mv /var/log /home
ln -s /home/log /var/log
vi /var/cpanel/jailshell-additional-mounts
- add /home/log to a blank line
- save the file
Autoresponders should now work properly with the log folder in a new location.
