I would but haven't the first clue what to do with this: http://www.mail-archive.com/linux-btrfs@xxxxxxxxxxxxxxx/msg19572.html This happens even with no data, so I can dd the entire missing device into a sparse file: dd to img, cp --sparse, tar with -Sj. The 80GB /dev/sdb becomes 2.5K. It's here now: https://dl.dropbox.com/u/3253801/devsdb_image_sparse.img.tar.bz2 And by the time I've done all that, the "*** Some devices missing" message is still present with 'btrfs fi show' Or since it's a VM that I don't care about at all, I can give you login info.
