Hi all,
I am running a home-grown Linux 2.6.20.11 SMP 64-bit build, and I am
wondering if there is indeed a RAID 10 "personality" defined in md
that can be implemented using mdadm. If so, is it available in
2.6.20.11, or is it in a later kernel version? In the past, to create
RAID 10, I created RAID 1's and a RAID 0, so an 8 drive RAID 10 would
actually consist of 5 md devices (four RAID 1's and one RAID 0). But
if I could just use RAID 10 natively, and simply create one RAID 10,
that would of course be better both in terms of management and
probably performance I would guess. Is this possible?
Yes, and you are correct on the performance. Read the man page section
on "near" and "far" copies of data carefully, and some back posts to
this list. Most of us find that using far copies generates slightly
slower write performance and significantly better read performance.
