Hello. I was looking at the PDFs linked to from the wiki, and found this: http://kernel.org/pub/linux/kernel/people/hpa/raid6.pdf More specifically, section 4, starting on page 8. Am I understanding this correctly, in that with raid6, linux is capable of detecting if the content on 1 disk is corrupted, and reconstruct it from the remaining disks?
I ran md/raid6 for awhile, do you mean remap the bad sector on the fly? Linux/md raid does not do this afaik.
But it can recover from a single or double disk failure, I have had both happen.
