Спроси в #btrfs.

При попытке найти корень, сыпит ошибками.

btrfs-find-root /mnt/1/root_btrfs_2.img
ERROR: failed to read block groups: Input/output error
Superblock thinks the generation is 885180
Superblock thinks the level is 1
Found tree root at 6943277056 gen 885180 level 1

Корень у тебя живой. И суперблоки живые. А сдохло chunk tree, если я правильно понимаю.

Если уж искать корни btrfs-find-root-ом, то ищи корень chunk tree (3).

И что пишет ядро при монтировании? Дубликат chunk tree тоже мёртвый?

Вообще конкретно это сообщение я даже не могу найти в коде btrfs-progs.

[ 186.142112] BTRFS error (device loop1): bad tree block start, want 6943834112 have 0

Это нашёл, но ни о чём не говорит. Ошибка в низкоуровневом коде чтения метаданных с диска, где именно он споткнулся — не понятно.

Короче, пиши в #btrfs. Ещё можешь btrfs restore попробовать, если нужно именно файлы спасти.

Этот раздел просто под корень. Хомяк на другом разделе. Хотел восстановить, чтобы не переустанавливать систему. Так наверно придется переставить, а играться с попытками восстановления можно будет и с образом.

Короче, пиши в #btrfs.

Как же я не люблю ирц, так сильно что всякое желание писать пропадает. :-(

Ты не знаешь правильно ли я понимаю? Если бы у меня раздел так же был бы один, но корень и /var были бы разнесены по подтомам. То при этой ошибке все равно умерла бы фс целиком и оба подтома были бы так же недоступны?

По хорошему давно стоило ее потестировать на производительность, но как то все времени не было. У меня есть флешка спасительная с линем, я думал на ней сначала опробовать эту фс. А на основной системе было страшновато использовать, система молодая, мало ли что. LUL

Всё, разобрался. Это extent tree.

Во-первых, попробуй btrfs check --repair --init-extent-tree.

Если не поможет, то btrfs restore должен сработать — если я правильно понимаю, extent tree непосредственно при чтении данных не используется. Всё проще, чем переустанавливать.

Ну и стандартное предупреждение — btrfs check --repair нужно делать на отдельной копии образа.

repair не помог. Сделал restore. Как докопируется попробую запуститься с этого корня. Но что то меня гложут сомненья в работоспособности системы. Как я понимаю симлинки не восстановились и атрибуиы файлов были утеряны.

Мне, возможно, везёт, но я её везде использую уже не один год без всяких проблем. Отключения случаются. Сейчас вот думаю, на новый SSD переезжать с только Btrfs, либо ext4 + ZFS, либо ext4 + Btrfs (ext4 для корня).

Выходит что ты прав. Попытка загрузиться провалилась. Права на все востановленные файлы поставились -rw-r–r– Я не долго думая сделал chmod -R +x * И раскидал симлинков на sbin bin lib в соответствующие каталоги в usr. Да еще и симлинк на /sbin/init сделал. Но все равно при загрузке системы ядро крашится при попытке переключить рут с ramfs на основной.

Это про NTFS, не умеющую контрольные суммы. А в Btrfs ты можешь потерять разве что всю ФС, но ничего испорчено не будет, восстановишь просто из резервной копии.

Вот это другое дело. :-)

Я в процессе восстановления нашел бекап системы и уже настроился из него восстановиться и как то даже не подумал почитать про возможные опции restore. С такими опциями восстановилось все удачно. Система загрузилась и работает. Спасибо за помощь.

P.S. В процессе восстановления проблемы возникли с 2 файлами.

We seem to be looping a lot on /mnt/restore/var/lib/clamav/daily.cld, do you want to keep going on ? (y/N/a):

Как раз понятно почему. Как я написал, extent tree вообще говоря при чтении данных не используется. В GRUB экстремально упрощённый драйвер btrfs, который игнорирует всё, что не нужно для минимальной задачи «прочесть файл».

Бекар на другом HDD. Довольно старый. Я не делаю их на регулярной основе. Этот был сделан в ходе эксперимента. Бекапы корня как по мне позволяют сэкономить время на восстановлении но не принципиально. Все более или менее интересные конфиги у меня регулярно бекапятся. И восстановить систему дело пары часов максимум.
