Tenho usado o webmin para gerenciar meu array RAID por vários anos, e nunca tive nenhum motivo para usar os comandos mdadm no terminal.
No entanto, alguns dias atrás, adicionei um disco à minha matriz RAID6 de seis unidades e não houve progresso na reformulação. Eu assumi que se eu reiniciar o computador, o problema seria resolvido, mas depois da reinicialização estou com um problema maior agora.
Embora a matriz esteja em um estado limpo após a reinicialização, não consigo iniciar a matriz em / dev / md3. Veja os comandos e as capturas de tela webmin anexadas.
