The real problem is that in a striped array one of the drives will seem to be bigger than it
really is. In the 2.4 kernel the ataraid module had a feature where it suppressed the
partitions on the individual drives from the system. In the 2.6 kernel dmraid doesn't suppress
them. So far I have found that 1) I can't use any labels in fstab or it will trigger the
seeking errors problem. 2) have to edit the hal filter also 3) have to edit the lvm filter 4)
and now have to edit the udev filter. It's getting to be a bit of a pain. Smiles.
