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.
The scope of this article does not discuss how to mount and format your disk. To utilize the additional disk, you can add this through "WHM >> Basic WebHost Manager® Setup":
Enter the location where you wish for new users' home directories to be created. Select a location in your server's file system to contain all of your cPanel users' home directories, or enter one in the text box.
Additional home directories matching the following value will also be used for new home directory creations.
Select an additional directory that you wish to use to store your cPanel users' home directories, or enter one in the text box. If you use more than one directory to store cPanel accounts, the directory with the most free space automatically stores new accounts.
This option only accepts one value.
