Hi, Kernel 3.12-rc built from HEAD has the same issue as 3.10 and 3.11 Ok, I was able to "fix" my problem by booting from an old kernel (3.8.7) and it allowed me to mount the fs. Then I removed /var/log/journal directory. After that I was able to boot with 3.11. So I believe 3.9/3.10 has a regression in how it handles COW files. As I described above, some time ago I defraged journald files and set +C attribute to /var/log/journal (both to the folders and existing files). So 3.11 boots fine and the only boot warning I see is Oct 11 19:06:55 brest kernel: BTRFS error (device sdd3): block group 1141416919040 has wrong amount of free space Oct 11 19:06:55 brest kernel: BTRFS error (device sdd3): failed to load free space cache for block group 1141416919040 I tried 'btrfsck -repair' but it crashes so I cannot even check or repair my btrfs mount. -- 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
