linux 环境 umount target is busy

"umount target is busy" 错误通常在尝试卸载正在使用的文件系统或设备时出现。这种情况下，你需要找出正在使用该目标的进程并停止它或释放它正在使用的资源。

你可以使用以下命令找出正在占用目标的进程：

sudo fuser -m /mount/point

将 "/mount/point" 替换为你要卸载的文件系统或设备的实际挂载点。这将显示正在使用目标的进程 ID（PID）。

然后，你可以使用以下命令终止进程或尝试优雅地关闭它：

sudo kill -TERM <PID>

将 "<PID>" 替换为你从 `fuser` 命令中获得的实际进程 ID。

一旦进程被终止或释放了资源，你就可以成功卸载目标，而不会遇到 "umount target is busy" 错误。

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.

如果在执行umount命令时出现"umount目标忙"的错误，说明目标文件系统、目录或文件正在被其他进程占用，无法卸载。您可以按照以下步骤解决该问题：

1. 使用lsof命令查找使用目标的进程信息：`lsof /mnt/test/`。该命令将显示正在使用该目标的进程和进程ID。
2. 使用fuser命令查找使用目标的进程信息：`fuser -mv /mnt/test/`。该命令将显示正在使用该目标的进程、进程ID和权限。
3. 终止占用目标的进程：`kill -9 <进程ID>`。请注意，终止进程可能导致数据丢失，请谨慎操作。
4. 再次使用umount命令卸载目标：`umount /mnt/test/`。

请注意，以上步骤中的`/mnt/test/`是一个示例目录，您需要将其替换为您实际要卸载的目标路径。
