Eu tentei btrfs recue chunk-recover -y <dev>:

Finalmente, ainda não consigo montar este disco com o erro do "tipo incorreto de fs":

vivodo@esper:~|⇒  sudo mount /dev/sdd /mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdd, missing codepage or helper program, or other error.
vivodo@esper:~|⇒  sudo mount -t btrfs -o compress=lzo /dev/sdd /mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdd, missing codepage or helper program, or other error.

O que mais posso fazer para recuperar meu disco btrfs?

PS, o ArchLinux Wiki diz que "existe um erro no systemd ou no mkinitcpio que causa o seguinte erro em sistemas com sistema de arquivos Btrfs para vários dispositivos usando o gancho btrfs no mkinitcpio.conf" ... Eu tenho vários sistemas de arquivos btrfs no meu host, mas eles não estão relacionados. Talvez não seja esse o caso.
