Any ideas what this could mean? I'm having this trouble with a system which is so messed up that I even can't restore $ sudo btrfs restore /dev/loop2p1 /mnt/data_extension/restore parent transid verify failed on 1068982272 wanted 47618 found 47575 parent transid verify failed on 1068982272 wanted 47618 found 47575 parent transid verify failed on 1068982272 wanted 47618 found 47575 parent transid verify failed on 1068982272 wanted 47618 found 47575 Ignoring transid failure leaf parent key incorrect 1068982272 Couldn't setup extent tree parent transid verify failed on 1068982272 wanted 47618 found 47575 Ignoring transid failure leaf parent key incorrect 1068982272 Couldn't read fs root: -1 I'm issueing the command because it seems to be the last thing I can do to rescue any data of that partition. This occurs with v3.12 (output of `btrfs --version`) as well as the latest commit 24cf4d8c3ee924b474f68514e0167cc2e602a48d of btrfs-progs.
