Mike, > Why not use Raid-10 instead of this more complex setup?
I don't much about RAID10, and it's an mdadm special case. I felt it was cleaner to just have two separate arrays (well, three..). Also, I need to remove half the array on a regular basis, and rejoin it afterware for resync. I'm going to read about RAID10 and see if I can do that. >> Can grub2 boot such a nested configuration?

(+ > a small /boot RAID-1 partition) Yes, thanks for the tip. I didn't know about 0.90 vs. 1.0 superblock size limitation. (It would be frustrating to discover when I want to go past 2TB!) It is planned for Grub2 to support booting from 1.0 superblocks?
