Hey all,

Over the last several months there have been many claims regarding the
release of the rewritten btrfsck. Unfortunately, despite numerous
claims that it will be released Real Soon Now(c), I have yet to see
even a repository with preliminary code. Did I miss an announcement?
There is something to be said for "release early, release often." Is
there a timeline for getting btrfsck into some sort of usable form?

I can't speak for the devs, but that's never stopped me before :p

Speculative code to directly muck with known-to-be-corrupted data
structures is not something that benefits from early releases.  It's
too easy to cause damage that _can't_ be fixed later, and no amount of
warnings will prevent people from trying that code in desperation.

Or would you have taken a full image of your 8 drives before trying it
the first time?
