There are more-or-less standard raid LEVELS, including raid10 (which is the same as raid1+0, or a stripe on top of mirrors - note it does not mean 4 drives, you can use 6 - stripe over 3 mirrors each of 2 components; or the reverse - stripe over 2 mirrors of 3 components each etc).
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.
