Problemas con disco duro?

Gracias Guille por la pista

En fin, ha vuelto a caer el servidor, y han abierto automáticamente un ticket para reemplazar el disco duro, ni me ha dado tiempo a pedirlo yo jeje. Esperemos que no tarde mucho y así pueda ponerme cuanto antes a reinstalar todo

Un saludo

La pista está aqui:
5 Reallocated_Sector_Ct 0x0033 052 052 036 Pre-fail Always
52 sectores reubicados por fallos seguramente de la superficie del disco.

Creo que con esos valores OVH debería cambiarte el disco.

Hola

Desde hace unas horas algunos servicios de mi servidor ha dejado de responder (por ej. Apache, aunque otros como FTP o SSH funcionan). He estado analizando la causa y parece que el sistema de archivos ha pasado a ser de solo lectura, obtengo este error: Read-only file system (errno = 30)

El caso es que esto me sucedió hace un mes y acabé formateando, desde entonces ha estado funcionando pero ahora ha vuelto a ocurrir. Desde hace un par de días notaba que las páginas tardaban más en generarse, esta mañana ya era insoportable (en procesar un PHP que suele tardar 0.05 segundos estaba tardando hasta 20 segundos) y lo he reiniciado. Ha estado funcionando hasta un par de horas después, que como digo parece que el sistema de archivos ha pasado a "solo lectura".

Ya he confirmado que no se trata de un ataque. Creo que podría ser el disco duro, pero no soy un experto para interpretar los datos de smartctl. ¿Podría ser eso y en su caso solicitar el cambio de disco?

Depués he intentado repararlo mediante fsck pero no he tenido éxito, y de hecho tras reiniciar el servidor no ha vuelto a arrancar (con el vKVM he visto que da un kernel panic por no poder montar el sistema de archivos).

Gracias a quien me pueda echar un cable. Adjunto resultado de smartctl y fsck.

Saludos

Edito: tras el vKVM he pasado los tests del modo rescue (sin errores salvo los del smart del disco), y al reiniciarlo desde el HD ha vuelto a arrancar, aunque ha tardado 20 minutos. Ahora mismo parece ir bien.
