Linux 强行取消挂载
Linux系统有时需要取消挂载一些设备或者目录,
# /dev/sdb挂载到了 /mnt/usb
umount /mnt/usb
但是多半会提示:
umount: /mnt/usb: target is busy
如果已 备份 了数据需要强行卸载,并且尝试 umount -f /mnt/usb
还是失败的情况
可以使用命令:
fuser -cu /mnt/usb #查看挂载文件进程
fuser -mv /dev/sdb #或者查看挂载点进程
fuser -ck /mnt/usb #结束进程
fuser -mk /dev/sdb #使用挂载点结束进程
或者使用 懒卸载 方式,命令执行后系统会自动关闭相关进程后再卸载:
umount -l /mnt/usb
