Why would it create a second MD with the same UUID as an existing
one? I have never seen this behaviour in 7 years of mdadm
development. Which version are you running?

I appreciate your work on the patch. It seems a bit large. Do you
need to factor our __load_superblock? Or would it be possible to
create a minimal version?

Thanks,
