Um dos nossos QNAP NAS caiu enquanto alertava em disco, assim eles estavam todos trabalhando / acessíveis no array. E estou tentando recuperar os dados, pois o QNAP NAS não inicializa nem responde com / sem os discos.
Eu inicializei todos os HDDs usando um disco ao vivo do Ubuntu com o comando mdadm . Não tenho certeza do que aconteceu com o disco um, pois mostra HPFS / NTFS / exFAT na partição 3 de um disco. Além disso, o UUID *, que supõe alguns números exclusivos, é mostrado como ** 0000: 0000 .... junto com Raid level: unknown .
Abaixo estão alguns resultados úteis que eu colecionei.

Alguém pode apontar o que eu fiz de errado aqui, ou estou faltando alguma coisa?
Estou realmente preso a isso e se alguém puder ajudar a recuperar DATA, puxando o RAID.
