Eu perdi uma unidade, então parei minha matriz, mudei a unidade, remontei a matriz.
Até agora tudo bem, exceto que quando eu tentei montar o array eu tive um erro sobre o sistema de arquivos md0 (desculpe, eu reiniciei para que não possa colá-lo do dmesg, algo como ioctl falhou ..) Então eu fiz um sudo fsck -f -y /dev/md0 retrospectivamente, eu acho um erro, mas isso é feito agora ...
Agora posso montar sem problemas meu array usando sudo mount /dev/md0 /media/raid5
O problema é que não há dados quando eu emito um ls -la /media/raid5 exceto um monte de coisas em lost + found ...
colei abaixo algumas coisas que podem ajudar; perdi meus dados ou é recuperável?
A coisa que eu acho "estranho" é o tamanho da matriz no detalhe, não sei se é relacionado, mas Array Size: 7813527552 parece correto, enquanto usado Dev Tamanho: 1953381888 parece muito baixo, na verdade o tamanho dos dados que eu m faltando é exatamente a diferença, 5To ..
df - h me diz que eu uso os 5To, parece que eles estão "escondidos" em lost + found, não são? se esse é o caso, algum meio de recuperá-lo, mesmo parcialmente?
