RAID-6 now in 2.6.1-mm

RAID-6 now in 2.6.1-mm

[H. Peter Anvin]

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

Can anyone explain how RAID6 works?  I understand RAID5, XOR, but I don't
see how that could be extended to allow any 2 disks to fail.

Thanks.

If you want the gory details, I've written a short paper on it:
