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. -- Moshe Yudkowsky * moshe@pobox.com * www.pobox.com/~moshe "You may not be interested in war, but war is interested in you." -- Leon Trotsky
