Just to point out - if this is raid-10 (and not raid-1+0 which is a
completely different beast) this is actually a normal linux config. I'm
planning to set up a raid-10 across 3 devices. What happens is that is
that raid-10 writes X copies across Y devices. If X = Y then it's a
normal mirror config, if X > Y it makes good use of space (and if X < Y
it doesn't make sense :-)
IMO, odd-numbered disks in RAID-10 should be considered harmful and
never used....
agreed and then "writemostly" could work without the lame excues that
one could have a crazy RAID10 layout.....
