How it got into this state is probably easy. Various people on the list say "don't use badblocks !!!" - it's a mess. The easy way to fix that is simply to assemble the array with --force-no-badblocks or whatever.

The concern with that is if the problem is actually nothing to do with badblocks itself, and everything to do with what's underneath them. So don't be too hasty.

I'll leave it to the experts to dig into your problem in more detail.
