了解 USB 消息日誌以對 USB 自動掛載進行故障排除
我正在嘗試解決一個問題,即在一台伺服器上我的 USB 自動掛載,而在另一台伺服器上卻沒有。比較兩個實例的日誌,我試圖了解每一行的含義。
自動掛載 USB 消息日誌:

- 核心如何確定使用哪個 USB
usb 2-1.4
版本usb 3-7
?- 是什麼
sd 4:0:0:0:
意思?另外,我正在嘗試在工作箱上複製自動安裝問題。我做了一個快速比較,發現兩個盒子上的 linux utils 版本不同,non-working 有一個舊版本(util-linux-ng-2.18),而 working 有一個新版本(util-linux-2.28)。有誰知道這是否會影響 USB 自動掛載?
1)那不是“USB版本”,它是USB-Tree中USB埠是您連接硬體的位置。實際編號由硬體和核心初始化 USB 根集線器和分配匯流排編號的順序決定。
lsusb -t
如果您好奇,請使用查看 USB 樹。2)
4:0:0:0
表示它被分配了 4 號 SCSI 匯流排,並且該匯流排上只有一個設備(它是虛擬匯流排,因為 USB 儲存協議本質上是 SCSI)。對13:0:0:0
.sd
是 SCSI 磁碟核心子系統(或者可能是“儲存磁碟”,不知道……),類似於st
(磁帶)等。3)這些都不會幫助您解決自動安裝問題。在兩台主機上都檢測到硬體和分區都很好,並且一台主機配置為自動掛載它,而另一台則沒有。
自動掛載有多種方式,所以第一步是找出你在一台主機上安裝的方式,然後在第二台主機上進行配置和安裝。
