Oh - I wonder if the layering of RAID like this is causing the
mkfs code to get confused. (is Martin lurking on the list?)
I'd suggest trying a mkfs on one of the RAID5 devices, then pass
those sunit and swidth values into mkfs rather than using the
ones which it figures out on the fly from your RAID0 device, and
see if that helps at all.

There were changes recently in the MD stripe detection code, just
to change it so that it wouldn't quit out of mkfs in certain cases
and instead warn and carry on - so that wouldn't affect you here.
It's a good idea to get the latest tools though - you might find
version 2 logs to be of some help here too, and there was a recent
mkfs fix for those recently.
cheers.
