RAID-5 or RAID-6 with mdadm 1.9.0-4 and 2.6.11.9

RAID-5 or RAID-6 with mdadm 1.9.0-4 and 2.6.11.9

[Ewan Grantham]

A rather specific question, I know. But I'm intrigued by some of the
things I've read about what RAID-6 offers. On the other hand, given
the version of mdadm and the Linux kernel I'm running, I'm wondering
which would be more stable and/or give better performance.

Thanks,
Ean

I'm running both RAID-5 and RAID-6 on 2.6.11.7 and they work a treat.

RAID-6 saved me from a dual drive failure a little while back, where a 2nd drive developed (or 
noticed) grown defects during the rebuild of the first failed drive (it takes about 15 hours to 
rebuild this RAID-6)
