我正在尝试解决以下问题：在一台服务器上我的 USB 自动挂载，而在另一台服务器上则不然。比较两个实例的日志，我试图理解每一行的含义。

内核如何确定使用哪个 USB
usb 2-1.4版本usb 3-7？这是什么
sd 4:0:0:0:意思？
另外，我正在尝试在工作盒上复制自动安装问题。我进行了快速比较，发现两个机器上的 linux utils 版本不同，非工作有较旧的版本（util-linux-ng-2.18），而工作有较新的版本（util-linux-2.28）。有谁知道这是否会影响 USB 自动挂载？
答案1
1) 这不是“USB 版本”，它是 USB 树中连接硬件的 USB 端口的位置。实际数量由硬件和内核初始化 USB 根集线器并分配总线编号的顺序决定。如果您好奇的话，可以使用lsusb -t查看 USB 树。
2)4:0:0:0表示它被分配了SCSI总线编号4，并且该总线上只有一个设备（它是虚拟总线，因为USB存储协议本质上是SCSI）。对于 也一样13:0:0:0。sd是 SCSI 磁盘内核子系统（或者可能是“存储磁盘”，不知道...），类似于st（磁带）等。
3）这些都无助于解决您的自动安装问题。在两台主机上均检测到硬件和分区正常，并且一台主机配置为自动挂载它，而另一台主机则不然。
进行自动挂载的方法有多种，因此第一步是找出您在一台主机上安装的方式，然后在第二台主机上配置并安装它。
