Hi, I just went thru a couple of papers describing RAID6. I dunno how relevant this discussion grp is for the qry ...but here I go :) ... I couldnt figure out why is P+Q configuration better over P+q' where q' == P. What I mean is instead of calculating a new checksum (thru a lot of GF theory etc) just store the parity block (P)again. In this case as well we have the same amount of fault tolerance or not :-s ... Let me know, here are the links which I went thru. http://kernel.org/pub/linux/kernel/people/hpa/raid6.pdf http://www.intel.com/design/storage/papers/308122.htm Regards, Amritanshu. - 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
