You could create the RAID first and the overlay afterwards.
Or you can create loop devices on the busy devices and use those.
I solved it by creating loop devices and use dd. I let it finish, then
ran fsck and resize2fs on the partition and now my data is back!

Thank you all for your invaluable help!

Would it be worth it for me to write up an article on the wiki on how to
re-create messed up metadata?

Hey - I was planning to do that! :-)

Seriously, yes of course, please do. That would be wonderful. It belongs best after "Recovering a damaged RAID" in the "When things go Wrogn" section, i think.

Just skim the contribution guidelines before you start, they're nothing onerous, just use good English and use "I" a lot, take responsibility for what you write. It's meant to be easy reading but informative. A case study of what you did would be marvelous.

I need to edit the page about that script you ran, and put a big big warning in front of it not to run it recklessly :-)

(Contact me off-line if you haven't got an account and have difficulty creating one.)

Cheers,
Wol
