Well, you need to first create a 100mb /boot partition on one of the 
drives, preferably the master drive that the bootloader will be 
installed on. There are two options:

For the rest of the drives create an LVM partition on each one, then 
create a Logical Volume group, so you have 3 8.5gb LVM volumes in one 
group. Make the LVM group your "/" partition, then you will have ~25gb 
of space.

You could do something similar by creating Software RAID partitions 
instead of LVM, and setup a RAID 0 (striped across all 3 drives) array 
to mount /.

In either case, make sure you make a swap partition on one of the 
drives. I am currently using a 75gb LVM on /dev/hda and a 35gb LVM on 
/dev/hdb, which gives mes a "/" filesystem of 110gb. Works very well and 
I have had no problems yet.
