What do you get for:

btrfs insp dump-s -f /dev/dm-0

See attached file "btrfs_insp_dump-s_-f.txt"

I'm on PTO this week so I'll be a little less responsive, but thankfully this is 
just the extent tree.  First thing is to make sure you've backed everything up, 
and then you should be able to just do btrfs check --repair and it should fix it 
for you.

However I've noticed some failure cases where it won't fix transid errors 
sometimes because it errors out trying to read the things.  If that happens just 
let me know, I have a private branch with fsck changes to address this class of 
problems and I can point you at that.  I'd rather wait to make sure the normal 
fsck won't work first tho, just in case.  Thanks,

Josef
