Hi Guys, I've tried to do all possible things by myself, but unfortunately all have failed. Therefore I'm looking for your help to get back my valuable data as FS failed at the time before I was able to finish backup tasks The error I'm getting is: # mount -o ro,nospace_cache /mnt/btrfs-backup/btrfs_backup.img /mnt/ssd-source/ [ 4417.684213] parent transid verify failed on 46587904 wanted 10081 found 10212 [ 4417.696899] parent transid verify failed on 46587904 wanted 10081 found 10212 [ 4417.728226] btrfs: open_ctree failed [ 4494.525556] device fsid c21fcec1-ab9a-4661-a9c0-25899886c91a devid 1 transid 10209 /dev/loop0 [ 4494.525570] device fsid c21fcec1-ab9a-4661-a9c0-25899886c91a devid 1 transid 10209 /dev/loop0 [ 4494.526924] btrfs: disabling disk space caching [ 4494.529273] device fsid c21fcec1-ab9a-4661-a9c0-25899886c91a devid 1 transid 10209 /dev/loop0 [ 4494.533728] parent transid verify failed on 46587904 wanted 10081 found 10212 [ 4494.533901] parent transid verify failed on 46587904 wanted 10081 found 10212 [ 4494.569029] btrfs: open_ctree failed # ./btrfsck /mnt/btrfs-backup/btrfs_backup.img # full output: http://bpaste.net/show/GeJtOSSLwcAvrD4BJIey/ [cut] parent transid verify failed on 55267328 wanted 10099 found 10212 Ignoring transid failure Check tree block failed, want=52756480, have=4325488229236153881 Check tree block failed, want=52756480, have=4325488229236153881 Check tree block failed, want=52756480, have=4325488229236153881 Check tree block failed, want=52756480, have=4325488229236153881 Check tree block failed, want=52756480, have=4325488229236153881 read block failed check_tree_block btrfsck: cmds-check.c:2214: check_owner_ref: Assertion `!(rec->is_root)' failed.

At the boot time, system did not mount root fs sitting on BTRFS. Having some experience, I've done some research and: 1. Made copy of my FS into file to work on this only to make sure I can always revert back to original FS with issue and restart recovery procedure from scratch 2. Built another system with full tool set to easily manipulate my FS image. 3. Pulled latest git clone git://github.com/josefbacik/btrfs-progs.git and built tools 4. Used latest tools trying to fix problem. I've checked multiple articles on the net and have tried following. ./btrfs restore /mnt/btrfs-backup/btrfs_backup.img /mnt/btrfs-restore/restore/ http://bpaste.net/show/fEXWHpRrVK8RBfKuhrjs/ System is: 3.11.0-12-generic #19-Ubuntu Btrfs tools were polled and compiled today. Any help would be highly appreciated, as I've said, I've just moved all my data from other faulty drive and backup task did not finish, therefore I've just one copy of my data sitting on this BTRFS :( Regards, Dawid -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
