md0, md1이 삭제되어 다시 만들 수 없습니다.

이전에는 RAID 1 어레이를 사용할 수 있었습니다. 어떻게든 및 을 grub-install /dev/sdb지운 것 같습니다 .grub-install /dev/sdcmd0md1

재설정해야 해요. 배열을 만들려고 하면 md0다음 오류가 발생합니다.

/dev# mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 missing -f
mdadm: device /dev/sda1 not suitable for any style of array

데비안은 드라이브가 이미 어레이에 있다고 생각하는 것 같지만 그렇지 않습니다.

편집: 출력을 설치하지 마십시오. md0에 설치된 것으로 표시되는데 /왜 에는 표시되지 않습니까 proc/mdstat?

추가 정보: 내 작업 RAID 어레이에는 md0 및 md1이 있고 드라이브는 sdb 및 sdc입니다. 나는 이러한 grub-install명령을 실행했습니다. 며칠 후 다시 시작하려고 시도했지만 다음 오류가 발생했습니다 md0.

Gave up waiting for boot device
ALERT /dev/disk/by-uuid/38[...] does not exist

그래서 두 번째와 세 번째 하드 드라이브를 분리했는데 GRUB이 md0으로 설정되어 있으면 부팅되지 않습니다. 그래서 md0으로 설정했는데 이것이 dev/sda1현재 내 컴퓨터의 상태입니다.
