通过 sshfs 安装树莓派设备：
sshfs osmc@rpi.: /home/user/pi
安装信息：
user@azimuth:~$ mount | grep osmc
osmc@rpi.: on /home/user/pi type fuse.sshfs (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000)
为什么我无法卸载？
user@azimuth:~$ sudo umount /home/user/pi
[sudo] password for user:
umount: /home/user/pi: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)
如何卸载 sshfs 共享？
更新：
user@azimuth:~$ sudo lsof | grep /home/user/pi
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
Output information may be incomplete.
lsof: WARNING: can't stat() fuse.sshfs file system /home/user/nas
Output information may be incomplete.
由于 sshfs 使用
fuse，您需要使用fusermount -u来卸载它：
