当你尝试卸载一个设备时,可能会遇到"device is busy"的错误。这个错误表示设备仍然被其他进程使用,所以无法卸载。解决这个问题的方法有几种。
一种方法是使用fuser命令来查找正在访问该设备的进程。你可以使用以下命令查找与/mnt挂载点相关的进程号:
fuser -c /mnt
另一种方法是使用lsof命令来查找正在使用该设备的进程。你可以使用以下命令查找与/mnt挂载点相关的进程:
lsof | grep /mnt
找到相关的进程后,你可以结束这些进程,然后再尝试卸载设备。你可以使用以下命令结束进程:
kill -9 进程号
完成上述步骤后,你应该可以成功卸载设备。

linux umount target is busy
The error message "umount target is busy" in Linux means that the filesystem or device you are trying to unmount is currently in use by some process, and cannot be unmounted until that process releases it.
To fix this, you will need to identify the process that is using the target and terminate it or release the resource it is using. You can use the `fuser` command to find out which process is using the target:
```
sudo fuser -m /mount/point
```
Replace "/mount/point" with the actual mount point of the filesystem or device you are trying to unmount. This will show you the process ID (PID) of the process that is using the target.
You can then use the `kill` command to terminate the process, or try to gracefully shut it down by sending a termination signal:
```
sudo kill -TERM <PID>
```
Replace "<PID>" with the actual process ID you obtained from the `fuser` command.
Once the process is terminated or the resource is released, you should be able to unmount the target without getting the "umount target is busy" error.
umount tmpfs
umount tmpfs是指卸载tmpfs文件系统的操作。tmpfs是一种基于内存的文件系统,可以在内存中创建一个临时文件系统,用于存储临时数据或缓存。在卸载tmpfs之前,需要确保没有任何进程正在使用该文件系统。如果有进程在使用tmpfs,会出现"device is busy"的错误提示。可以使用lsof或fuser命令来查找正在使用tmpfs的进程,并将其停止或解除与tmpfs的关联。在卸载tmpfs之前,还应备份重要的共享内存数据,以免丢失。可以通过修改/etc/fstab文件来修改tmpfs的容量大小。在文件中找到tmpfs行,并在size选项后面指定分配的空间大小。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
