df 挂起：设备 sdh1 上的缓冲区 I/O 错误，逻辑块 754166359，异步页面读取

在 Ubuntu 20.04 机器运行了一段时间后，我尝试运行df，但它只是挂在那里。

dmesg显示大量相同的错误消息：

下一步该怎么办？

我们可以卸载/dev/sdh1然后重新挂载它，以便df再次正常运行吗？如果是这样，我们如何找到的挂载点/dev/sdh1，以便我们可以运行命令sudo umount <mountpoint_of_/dev/sdh1>？

尝试了以下命令，但它们没有返回任何内容

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

答案1

您无需知道挂载点即可卸载它，只需知道设备名称即可。只需执行sudo umount /dev/sdh1。

如果您想识别挂载点，findmnt /dev/sdh1就足够了。
