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.
