I've already tested RAID-10 with MD as well as letting LVM do the striping. This is total equal: There are too many IO processes on all spindles for good performance. All r/w-heads in RAID-10 have to be repositioned over and over again. Even in random IO this only reads from a single spindle per RAID-1 array. Without striping MD RAID-1 has a good read balancing algorithm. With that I can read from both spindles in the RAID-1 array simultaneously. > For scripting, see Linux::LVM on CPAN.

Thanks, I'll look at that.
