Curiously, I would've thought the opposite, that is, bunch of separate
raid1 arrays would be easier to understand than raid10.
Raid1 is conceptually simple compared to any other raid level,
and if you're using lvm anyway, it doesn't make much difference
whether physical volumes are disks or disk pairs.
Anybody want to claim being a newbie and having an opinion here?
