设置磁带驱动器 + 自动转换器时，Bacula 中的输入/输出（读取）错误

在 bacula 中运行label barcode命令时，我收到输入/输出错误。我刚刚开始尝试进行设置：

Bacula 目录：

    # 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;
}

有人知道这是什么意思/为什么我会得到这个吗？

好的，由于以下配置错误：

  Media Type = LTO-4
  Media Type = File

看来我搞混了 bacula。命令中列出的介质list media类型为 File。所以我所做的就是删除池，然后尝试使用 重新扫描label barcode。但是，它被拒绝了，因为磁带上已经有 bacula 卷标。为了解决这个问题，我做了这个小循环：

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

然后，我这次能够label barcode再次运行，没有出现原始错误或“3920 无法标记卷，因为它已经被标记”错误。
