Are you sure this is software raid? I have to ask. What follows is only
true if you have software raid.
Does knoppix have the raid tools. Fedora uses mdadm to manage software
RAID. You will also need the raid device in /dev. On my server I have
/dev/md0 for /boot and /dev/md1 for everything else.
Also check to see if Knoppix can read XFS. Not all Linux distributions
can read XFS.
