I don't know... but after btrfs-zero-log now I can't: ivan@ipplus-dev:~$ sudo btrfs filesystem df /dev/sdb [sudo] password for ivan: ERROR: couldn't get space info - Inappropriate ioctl for device ERROR: get_df failed Inappropriate ioctl for device ivan@ipplus-dev:~$
So you're saying that I can't make first and third partition to work with it's data? Maybe I'll try with btrfs-restore, do you think it can rescue this 2 drives?
