mkraid creating 5G raid device from 110G partitions

Hello all,
I'm trying to create a RAID-1 array using 2 WD hard drives on a server running knoppix. For some reason mkraid /dev/md1 creates a raid device that is only 5 Gigs, however the partitions I am using in the array are about 110Gigs. This is urgent, so if the answer to this is out there but I havent found it on google yet, I apologize.
Here is the relevant Raid configuration:
The server is running knoppix 3.3, 2 WD 120Gig HD's, 2G Ram
mkraid version 0.90.0
root@0[mnt]# fdisk -l
