Me too.  I've got a 9TB filesystem that I can't mount since rebooting
during a rebalance.  I want to get the fs as repaired as possible, but
I am not in a hurry, and I have enough space at present to make a
duplicate and play with test versions of the repair.

 Yes, but its still real soon now.  I've been at about 90% done since
 Christmas.  It would have been out last week but I've been chasing a
 debugging a very difficult corruption under load.

 I finally found a race in btrfs causing the corruption and now I'm
 back on fsck full time again.

 This mail was about four month ago...
 Any news on this topic?

 I really would like to test btrfs on my desktop systems, but I still
 hesitate because of the missing fsck.

Glad to hear this. Thank you very much for your update. With respect to
the other thread (re: loose eSATA cable). I can keep the array around in
its current form if it would provide a good test case for btrfsck. That
being said, I'm really looking to recover some of the data from this
array if at all possible.

Cheers,

- Ben

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?
