Errores de entrada/salida (lectura) en Bacula al configurar una unidad de cinta + cambiador automático

Al ejecutar el label barcodecomando en bacula, obtengo errores de entrada/salida. Recién estoy comenzando a intentar configurar esto:

Bacula-dir:

    # Definition of file storage device
    Storage {
      Name = TapeDevice
    # Do not use "localhost" here    
      Address = ny-back01....     # N.B. Use a fully qualified name here
      SDPort = 9103
      Password = "..."
      Device = ULTRIUM-HH4
      Media Type = LTO-4
      Media Type = File
      Autochanger = Yes
    }

Bacula-sd:

Autochanger {
        Name = StorageLoader1U
        Device = ULTRIUM-HH4
        Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
        Changer Device = /dev/sg5
}

Device {
        Name = ULTRIUM-HH4
        Media Type = LTO-4
        Archive Device = /dev/st0
        AutomaticMount = yes;
        AlwaysOpen = yes;
        RemovableMedia = yes;
        RandomAccess = no;
        AutoChanger = yes;
        RandomAccess = no;
}

¿Alguien sabe lo que esto significa/por qué recibo esto?

Bien, debido al siguiente error de configuración:

  Media Type = LTO-4
  Media Type = File

Parece que confundí a Bacula. Los medios fueron enumerados en el list mediacomando como tipo Archivo. Entonces, lo que hice fue soltar el grupo y luego intentar volver a escanear con label barcode. Sin embargo, fue rechazado porque las cintas ya tenían la etiqueta de volumen de la bacula. Para solucionar esto hice este pequeño bucle:

for i in $(seq 1 8); do 
    /etc/bacula/scripts/mtx-changer /dev/sg5 load $i /dev/st0 0
    mt -f /dev/st0 rewind
    mt -f /dev/st0 weof
    /etc/bacula/scripts/mtx-changer /dev/sg5 unload $i /dev/st0 0
done

Luego pude ejecutar label barcodenuevamente esta vez sin el error original o el error "3920 No se puede etiquetar el volumen porque ya está etiquetado".
