Estou executando um servidor com o Software Raid 1 e ele é usado exclusivamente para fins de backup usando o Idera / R1Soft. Nos últimos dias, os backups foram gerados de forma extremamente lenta, por isso estou começando a me perguntar se há problemas de disco. No entanto, não tenho certeza se esse é o caso, então espero que alguém possa me ajudar a diagnosticar o problema.
Abaixo está um monte de informações dos discos, deixe-me saber se alguma coisa é necessária. Essas unidades parecem saudáveis ou o que parece ser o problema? O software de backup salva na partição / home /, então é provável que esse seja o problema.
Se um dos discos estiver com defeito, preciso enviar ao provedor do servidor uma prova disso, o que devo enviar?
Muito obrigado!
