What do the partition tables look like?
You may know this already, but you need to start the first partition on
each disk at cylinder 1 instead of cylinder 0 to leave room for the disk
label. Apparently, Ext2/3 leaves some free space at the start of
partitions for this sort of thing, but RAID doesn't.
