mounted raspberry pi device via sshfs:
sshfs osmc@rpi.: /home/user/pi
user@azimuth:~$ mount | grep osmc osmc@rpi.: on /home/user/pi type fuse.sshfs (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000)
Why am I unable to umount?
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).)
How to unmount the sshfs share?
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.
