Fallo de disco
Buenas,
Tengo un servidor Debian Stretch con varios discos, y uno de ellos
esta dando este error en el "dmesg":

Se repite muchas veces: https://paste.debian.net/1004844/
Veo que es en el disco sdb1.

¿Que puedo hacer?
Veo en los logs que el error es siempre en el mismo "block" y diferente "inode":

¿Podría identificar el bloque y saber que tengo guardado?
Agradezco cualquier ayuda.
Un saludo.
