Here's a baseline question: if I create a RAID10 array using default
settings, what do I get? I thought I was getting RAID1+0; am I really?
My superblocks, by the way, are marked version 01; my metadata in
mdadm.conf asked for 1.2. I wonder what I really got. The real question
in my mind now is why grub can't find the info, and either it's because
of 1.2 superblocks or because of sub-partitioning of components.
