Hola, tuve problemas de comunicación entre el almacenamiento HP D6000 y mi servidor (que se ejecuta en redhat 7.3). Mi servidor HP D6000 proporciona un archivo /dev/sdc formateado en BTRFS
De hecho, desde mi servidor ya no tenía acceso a algún archivo o carpeta, al intentar leerlos/abrirlos obtuvimos un error de entrada de Linux.
Al observar el registro del sistema usando el comando dmesg, hemos visto que muchos mensajes de error estaban relacionados con btrfs. Ver dmesg_btrfs.log
