the problem is you have a misconfigured raid system
you can either have a raid system with
diskA + diskB (raid-level == linear )
or
diskA mirrored to diskB ( raid-level == 1 )

... okay .. but .. this just combines sda2 + sdb2 as "one disk"

the above says you have the same data on sda1 and sdb1 and hda11
if any of the partitions are not exactly the same sizes ( same number of
cylinders ) ... you're dead ..
- dont forget that some disk bios mapps 16 heads into 255 heads
and that makes things nice and messy

it'd be better if you highlighted what you thought was bad
like you did in fstab
