df 掛起：dev sdh1 上的緩衝區 I/O 錯誤，邏輯區塊 754166359，非同步頁面讀取

Ubuntu 20.04 機器運行一段時間後，我嘗試運行df，它只是掛在那裡。

dmesg顯示大量相同的錯誤訊息：

接下來我們該如何進行呢？

我們可以卸載/dev/sdh1然後重新安裝它，以便我們df再次正常運行嗎？如果是這樣，我們如何找到 的掛載點/dev/sdh1，以便我們可以執行該命令sudo umount <mountpoint_of_/dev/sdh1>？

嘗試了以下命令，但它們沒有返回任何內容

  • findmnt -S /dev/sdh
  • findmnt -S /dev/sdh1
  • grep /dev/sdh /etc/mtab
  • grep /dev/sdh1 /etc/mtab

答案1

您不需要知道安裝點即可卸載它，設備名稱就足夠了。做就是了sudo umount /dev/sdh1。

如果你想辨識掛載點，findmnt /dev/sdh1應該就夠了。
