? umount ?
> 今天，小伙操作服务器的时候忘了umount，结果服务器关闭之后，再次umount，发现报错如下： ```bash [root@app-2 ]# umount /home/logs/2 umount: /mnt/cdrom: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) ``` ？被占用，强制卸载 ```bash [root@app-2 ]# umount /home/logs/2 -f //强制卸载也不行 umount2: 设备或资源忙 umount: /home/logs/2: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) umount2: 设备或资源忙 ``` 不行，只好使用fuser ```bash [root@app-2 ]# fuser -m /home/logs/2 ``` 没有反应，查看路径发现没有问题，已经恢复。
觉得不错，点个赞？
