Eu queria substituir um dispositivo raid5 corrompido no meu sistema linux (opensuse 13.2), mas perdi o passo de set-faulty / remover o dispositivo (/ dev / sdc1).
Então, acidentalmente, apenas mudo o dispositivo com um novo disco clonado que leva a essa saída:
mdadm --detail /dev/md0
/dev/md0:

2 0 0 2 removed

4 8 65 4 active sync /dev/sde1
5 8 81 5 active sync /dev/sdf1
7 8 97 6 active sync /dev/sdg1
A remoção de sdc1 por mdadm --manage /dev/md0 -r /dev/sdc1 não removeu a entrada "removida" no dispositivo 2. Portanto, a matriz foi marcada como degradada.
Agora não sei como limpar o array de raid.
Edit: Aqui está a saída do mdadm --examine / dev / sd? 1:
