ZFS - A substituição do disco Zpool resulta no reinício do processo resilver que nunca termina

Question

Substitui uma unidade quebrada por um tipo já usado na minha piscina há algum tempo. O problema que enfrento é que o processo de resilver parece estar preso em um loop de reinicialização. Sempre que eu verifico o zpool status , vejo que o processo de resilver começou há alguns segundos. A porcentagem de progresso fica parada em 0%

por exemplo,

• scan: resilver em andamento desde Qui Jun 1 09:13:27 2017
• scan: resilver em andamento desde Qui Jun 1 09:15:10 2017
• scan: resilver em andamento desde Qui Jun 1 09:18:11 2017

...

Não tenho ideia do que está errado, nunca encontrei esse problema antes. Eu gostaria de receber alguns conselhos da comunidade.

Answer 1

Não consegui consertar isso e acabei substituindo o disco por outro, o que resolveu o problema. Eu suspeito que a unidade estava com defeito, mesmo quando nenhum erro SMART foi registrado.
