Howdy,
While moving data back to a brand new btrfs FS I had just created (with
3.14 tools and under 3.15), I got this:
legolas:/mnt/btrfs_pool2# for i in tmp_ro.20140507_09:00:31 root_ro.20140507_10:00:20 usr_ro.20140507_09:00:41 var_ro.20140507_09:00:58 home_ro.20140507_10:00:01; do btrfs send $i | btrfs receive /mnt/btrfs_pool1/; done

Same deal with merlin/.config/google-chrome-mysetup/
However, I see:

=> corruption too
I could believe that btrfs has an issue on the source drive, but
ls -l looks clean on the source, and clearly looks corrupted on the
destination after send/receive.
Any clues?
I'll try reverting to 3.14 if I have enough time this morning to see
if the error happens again.
Thanks,
Marc
