This is what I got:
myth:~# btrfs-find-root -a /dev/mapper/crypt_sdd1
Superblock thinks the generation is 39538
Superblock thinks the level is 1
Well block 4243456(gen: 3 level: 0) seems good, but generation/level doesn't match, want gen: 39538 level: 1
Well block 4194304(gen: 2 level: 0) seems good, but generation/level doesn't match, want gen: 39538 level: 1
myth:~#
Does it mean there is no other block I can/should use?
Thanks,
Marc
