As I read that algorithm on the RAID 6 are way more complex, and rebuild time is longer, as I have only a Atom D510 as CPU, I consider that RAID 5 is a better option.
It's an old myth that RAID6 uses a lot of CPU. It doesn't, not even considering you have an Atom D510.
But if you can explain that RAID 6 have pros I haven't seen, I'll surely swith to RAID 6 (always want to learn :) ).
RAID6 will help you with drive failure plus random read error. RAID5 doesn't do that.
My recommendation to you is to convert your RAID5+spare to RAID6. -- Mikael Abrahamsson email: swmike@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
