If /home is full on a cpanel server, how do we configure the /home on another partition?

add a new hard drive, format and mount it as /home2 after this is done, we have two options to tell cpanel to utilize /home2. Edit /etc/wwwacct.conf and set HOMEDIR as /home2. All new accounts will be created in /home2   or Edit /etc/wwwacct.conf and set HOMEMATCH as /home*. All new accounts will be created in /home or /home2 depending upon the amount of free space in /home or /home2
