If n+1 disks have bad blocks there's no data to sync over, so they just propagate and stay bad forever. Or at least that's how it seemed to work last time I tried it. I'm not familiar with bad blocks. I just turn it off. As long as the bad block list is empty you can --update=no-bbl. If everything else fails - edit the metadata or carefully recreate. Which I don't recommend because you can go wrong in a hundred ways. I don't remember if anyone ever had a proper solution to this. It came up a couple of times on the list so you could search. If you've replaced drives since, the drive that has been part of the array the longest is probably the most likely to still have valid data in there. That could be synced over to the other drives once the bbl is cleared. It might not matter, you'd have to check with your filesystems if they believe any files located there. (Filesystems sometimes maintain their own bad block lists so you'd have to check those too.)
