Hi all,
For those who haven't seen yet, RAID-6 has been integrated into the
2.6.1-mm kernels. Please test it out and let me know how it works
out.
The mdadm patch is still at:
ftp://ftp.kernel.org/pub/linux/kernel/people/hpa/
-hpa

I understand RAID5, XOR, but I don't see how that could be extended to allow any 2 disks to fail.
