Ciao a tutti, ho due hdd in raid 1
(sda e sdc)
, identici.
I dischi sono da 2 tb wd o segate mi pare, ho accesso solo da remoto in ssh alla macchina.
Da ieri il raid ha cominciato a fallire e nei log ho trovato questo:

o capito che ci sta un problema su di un settore, ma cosa mi consigliate di fare?
Questa mattina al riavvio del pc, il raid è composto di un solo hdd, che posso fare? formattare
l disco e provare a riunirlo? cosa posso controllare prima di sostituirlo fisicamente?
