Компьютер разбился, рейд-массив в беде

Я приехал домой сегодня и обнаружил, что мой домашний сервер отключен (не знаю почему). Снова включил его, и массив raid не смог подключиться.

/ proc / mdstat показывает:

Personalities : md0 : inactive sdh[7](S) sdc[2](S) sdd[1](S) sdb[3](S) sde[0](S) sdg[5](S) sdi[6](S) sdf[4](S) 39069143232 blocks super 1.2  unused devices: <none> 

и mdadm --detail / dev / md0 говорит, что уровень рейда равен raid0, тогда как на самом деле он должен быть raid6.

Глядя на mdadm -E на каждом отдельном диске. Все диски, кроме sdg, имеют состояние массива AAAAA.AA, число событий 191578 и состояние активно.

sdg, однако, имеет состояние массива AAAAAAAA и число событий 69286, и состояние чистое.

Также следует отметить, что UUID массива, показанный в -E, отличается от UUID массива, который я имею в /etc/mdadm.conf - хотя это может быть связано с проблемой, с которой я столкнулся в прошлом, когда машина зависала в начале роста и мне пришлось запустить, mdadm -CR /dev/md0 --metadata=1.2 --raid-devices=5 --level=6 -c512 /dev/sdb /dev/sdc /dev/sdd /dev/sdf /dev/sde --assume-cleanчто решило проблему, но я думаю, что это также изменило массив UUID.

Для справки: система содержит один загрузочный ssd (/ dev / sda), подключенный к материнской плате, и 8 дисков по 5 ТБ для массива raid 6 (/ dev / sdb через / dev / sdi), подключенного к dell perc H310 в режиме IT.

Вывод моего mdadm -E для всех дисков:
