Hi, I''m having a filesystem that''s been a bit mangled by external causes, so I thought I''d see how much I could salvage (it''s not critical, though). Thus, I pulled btrfsck from git and ran: pannekake:~/btrfs-progs# ./btrfsck --repair /dev/mapper/pannekake-backup-btrfs It spit out a ton of warnings like these (I can get the whole log if you''re interested): parent transid verify failed on 7007735808 wanted 8322 found 8856 Ignoring transid failure parent transid verify failed on 2895847424 wanted 8184 found 8818 Ignoring transid failure parent transid verify failed on 7007735808 wanted 8322 found 8856 Ignoring transid failure parent transid verify failed on 2895847424 wanted 8184 found 8818 Ignoring transid failure parent transid verify failed on 7007735808 wanted 8322 found 8856 Ignoring transid failure parent transid verify failed on 2895847424 wanted 8184 found 8818 Ignoring transid failure and then died with btrfsck: cmds-check.c:2212: check_owner_ref: Assertion `!(rec->is_root)'' failed. Aborted I assume this is a bug in btrfsck. :-) What more information do you need from me to be able to look at this? The filesystem is a bit too big (550GB) to transfer easily. /* Steinar */ -- Homepage: sesse.net -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at vger.kernel.org/majordomo-info.html
