Эй, после остановки во время обновления мой раздел btrfs не может смонтировать.Я перепробовал все из Вики Archlinux и BTRFS, которые смог найти, но этого было недостаточно.
То, что я пробовал, и вывод:
$ sudo mount -t btrfs / dev/ sda3 / mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sda3, missing codepage or helper program, or other error.
