Cover letter [Ocfs2-devel] [PATCH 0/18] ocfs2: Add metadata ECC - almost there.
Quoted 5 lines · Joel Becker
These patches add the metadata ECC code to ocfs2. They have one limitation - they do not ECC directory blocks yet. However, that will only take a simple insertion of the dirblock trailer. With xattr ECC completed, the patches are approaching a final form and are ready for initial review. They are atop my xattr-buckets-2 branch.
Could you please expand a bit why you chose ECC over more standard CRCs?
My assumption would be normally that if there is disk corruption it won't be single flipped bits, but more large scale corruption. Do you have data/experiences on the contrary?
Thanks,
