So the disk to possibly dd to another is the one with the write error, sdg1. But only if the idea is to not use --assume-clean. That way a reassemble can rebuild, and not encounter another write error on that drive.

I meant resync.

But isn't a resync a state where md assumes parity is dirty and must be recreated? If so, what happens when sdj1 encounters UREs? If there's untrusted parity, does md just use what it has, or does it stop the array?
