How to use an additional disk with cPanel

Question

There may be times you need to add additional disk space to the server and you want to store accounts on this additional disk. This can be done through the WHM interface.

Answer

1. Access your WHM server as the root user.
2. Navigate to WHM / Server Configuration / Basic WebHost Manager® Setup.

3. Locate the two values and set the additional home directory. 

   CONFIG_TEXT: Enter the location where you wish for new users’ home directories to be created. By default all directories matching the "Home Directory Prefix" are checked for available disk space and the directory with the most free space will be used.
   Example: /home
       
   Additional home directories matching the following value will also be used for new home directory creations. (Leaving this value blank disables the feature.) Only mount points are considered. This option only takes one value.
   Examples: “home” matches /home, /home2, /newhome, /usr/home, /anythingwith/homeinit
