Increasing the size of /tmp is not a practical thing to do on a busy server, mainly because you probably won't be able to dismount /tmp because it's constantly used by various services--trying to find and kill them all is too tedius. (Plus you won't be able to do single user mode through SSH)
So what we will do here is create a whole new /tmp storage location, make a backup of the old /tmp, add the new location to fstab, reboot the server, copy everything from the backup /tmpBKP location to new location, and lastly reboot the server again.
