Computador travado, raid array em apuros

0

Cheguei em casa hoje e descobri que meu servidor estava desligado (não sei por quê). Voltei a ligá-lo novamente e o arranjo de raid estava falhando em montar.

/ proc / mdstat mostra:

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>

e mdadm --detail / dev / md0 diz que o nível de raid é raid0, quando na verdade é suposto ser raid6.

Observando o mdadm -E em cada unidade individual. Todas as unidades separadas do sdg têm um estado de matriz de AAAAA.AA, uma contagem de eventos de 191578 e estado ativo.

O sdg, no entanto, possui um estado de array de AAAAAAAA e uma contagem de eventos de 69286, e o estado é limpo.

Além disso, a matriz UUID mostrada em -E é diferente da matriz UUID que eu tenho em /etc/mdadm.conf - embora isso possa ser devido a um problema que eu tive no passado em que a máquina falhou no início de crescer, e eu tive que executar mdadm -CR /dev/md0 --metadata=1.2 --raid-devices=5 --level=6 -c512 /dev/sdb /dev/sdc /dev/sdd /dev/sdf /dev/sde --assume-clean , que resolveu o problema, mas eu estou supondo que também mudou o UUID da matriz.

Para referência, o sistema contém um ssd de boot (/ dev / sda) conectado à placa-mãe e 8 drives de 5TB para o array raid 6 (/ dev / sdb a / dev / sdi) conectado a um dell perc H310 em IT Modo.

A saída do meu mdadm -E para todas as unidades:
