But unfortunately the process breaks with: parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 Ignoring transid failure checking extents parent transid verify failed on 34172928 wanted 392666 found 395689 parent transid verify failed on 34172928 wanted 392666 found 395689 parent transid verify failed on 34172928 wanted 392666 found 395689 parent transid verify failed on 34172928 wanted 392666 found 395689 Ignoring transid failure leaf parent key incorrect 34172928 btrfsck: btrfsck.c:1935: check_owner_ref: Assertion `!(rec->is_root)' failed. after that I tried to restore the data from disk unfortunately with an older Version of btrfs-restore. There are a lot of files I have restored but this process also breaks. (I can't remember the message). But after a second try (with old and the latest version) breaks now much earlier. Here is the output: parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 Ignoring transid failure Root objectid is 5 We seem to be looping a lot on /mnt/var/cache/apt-xapian-index/index.1/postlist.DB, do you want to keep going on ?
