Pessoal, boa noite. Espero que todos estejam bem! Sou novo no OpenMediaVault e confesso que estou um pouco desesperado.

Ontem à noite tive uma queda de energia devido a um problema no UPS que não segurou a falha.

Após reiniciar a máquina, notei que o RAID não havia subido. Em alguns comandos simples verifiquei que o mesmo ainda existe, mas não foi montado. No entanto, recebo um erro ao tentar montar.

Aqui estão alguns comandos que eu tentei: (eu entendo pouco de linux)...

root@OPENMEDIAVAULT:~# lsblk

Pelo amor de Jesus Cristo, tenho alguns dados EXTREMAMENTE IMPORTANTES dentro deste RAID e não posso perdê-los. Alguém por favor pode me ajudar? SEREI ETERNAMENTE GRATO!
