컴퓨터 추락, 습격 배열 문제

0

나는 오늘 내 집 서버가 꺼져 있다는 것을 알기 위해 집에 도착했다 (왜 그런지 모르겠다). 다시 켜고 RAID 어레이를 마운트하지 못했습니다.

/ proc / mdstat는 다음을 보여줍니다.

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>

mdadm --detail / dev / md0은 공격대가 실제로 raid6 인 경우 공격대 수준이 raid0이라고 말합니다.

각 개별 드라이브에서 mdadm -E를 살펴 봅니다. sdg를 제외한 모든 드라이브의 어레이 상태는 AAAAA.AA이며 이벤트 카운트는 191578이며 상태는 활성입니다.

그러나 sdg의 배열 상태는 AAAAAAAA이고 이벤트 수는 69286이며 상태는 깨끗합니다.

또한 -E에 표시된 배열 UUID는 /etc/mdadm.conf에있는 배열 UUID와 다릅니다. 이는 과거에 머신이 커질 때 충돌했던 문제로 인한 것일 수 있습니다. mdadm -CR /dev/md0 --metadata=1.2 --raid-devices=5 --level=6 -c512 /dev/sdb /dev/sdc /dev/sdd /dev/sdf /dev/sde --assume-clean문제를 해결 하기 위해 실행해야 했지만 배열 UUID도 변경되었다고 생각합니다.

참고로, 시스템에는 IT 모드에서 Dell Perc H310에 연결된 RAID 6 어레이 (/ dev / sdb-/ dev / sdi) 용 8 개의 5TB 드라이브와 마더 보드에 연결된 하나의 부트 ssd (/ dev / sda)가 있습니다.

모든 드라이브에 대한 내 mdadm -E의 출력 :

실제로 어레이를 시작해 보셨습니까? 비활성으로 표시됩니다.
— cdhowie
안녕 @ cdhowie-나는 이것을 해결했다. sdg가 파손되었습니다 (SMART 결과에 표시). 나는 그것을 제거하고 새 드라이브를 추가했습니다. 어레이가 시작되고 재 구축되었으며 이제 모든 것이 작동합니다.
— Azelphur
다행. 디스크가 없어도 어레이가 열화되지 않은 것은 이상하다.
— cdhowie
@ cdhowie 나는 두 가지 중 하나에 해당하는 느낌을 가지고 있습니다. 과거에는 다소 나쁜 실패였으며 --assume-clean으로 배열을 다시 작성해야했습니다. 이로 인해 어레이 UUID가 변경되었지만 /etc/mdadm.conf에서 UUID를 업데이트하지 않았습니다.
