Estoy ejecutando un servidor con Software Raid 1 y se utiliza únicamente con fines de copia de seguridad utilizando Idera/R1Soft. En los últimos días, las copias de seguridad se han generado muy lentamente, por lo que empiezo a preguntarme si hay problemas con el disco. Sin embargo, no estoy seguro de si este es el caso, así que espero que alguien pueda ayudarme a diagnosticar el problema.
A continuación se muestra mucha información sobre los discos; avíseme si necesita algo más. ¿Estas unidades parecen estar en buen estado o cuál parece ser el problema? El software de copia de seguridad se guarda en la partición /home/, por lo que probablemente aquí sea donde radica el problema.
Si uno de los discos está defectuoso, necesito enviar al proveedor del servidor un comprobante de ello, ¿qué envío?
¡Muchas gracias!

¿Ver todos los tipos de pre-falla? Si yo fuera tú, cambiaría ese disco lo antes posible.
