It is not possible to flip a bit to change a set of disks from RAID 1 to RAID 5, as the physical layout is different.
As Tuomas pointed out though, a 2 disk RAID5 is kind of a special case where all you have is data and parity which is actually also just data. Seems kind of like a RAID1 with extra overhead. I don't think I've ever heard of a RAID5 implementation willing to handle <3 drives though.
I suspect I should have just kept out of this, and waited for someone like Neil to answer authoratatively.
So...Neil, what's the right answer to Tuomas's 2 disk RAID5 question? :) ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________ - 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
