I don't think it's possible to have one partition spread over two or more disks.
However, you can take parts of one partition on one disk, and move those parts to other partitions on another disk.
Example: On one disk, you have one partition, and it's getting full. So, you add another disk, and make two or three partitions on it. Then move /home, /boot, /usr to new partitions. Edit /etc/fstab to show the new partitions and their mount points. Edit your boot loader to show the new location of /boot (if you move it to another partition).
The Partitioning HOWTO should help you with what to do and how to do it.
