Ubuntu – Unmount sshfs from mount point

sshfsumount

mounted raspberry pi device via sshfs:

sshfs osmc@rpi.: /home/user/pi

mounting information:

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?

UPDATES:

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.

Best Answer

Since sshfs uses fuse, you need to use fusermount -u to unmount it:

fusermount -u /home/user/pi

Ubuntu – Automatically mount sshfs on startup

Does Upstart in Ubuntu work with network events? For sure you can place scripts in /etc/network/if-up.d and /etc/network/if-down.d. There is a guide on Ubuntu Forums.

Ubuntu – How to auto mount using sshfs

You could create a launcher and add it to your launcher bar by drag&dropping the .desktop-file there:

    #!/usr/bin/env xdg-open

    [Desktop Entry]
    Version=1.0
    Type=Application
    Terminal=false
    Icon[en_US]=nautilus
    Name[en_US]=Connect to xy
    Exec=shfs user@192.xx.xx.xx.xx:/dir/dir /home/username/mount/xxx
    #OR: to mount and than open in nautilus (note the '/dir' where ':dir' used to be)
    #Exec=nautilus sftp://user@192.xx.xx.xx.xx/dir/dir
    Comment[en_US]=Connect to xy via ssh
    Name=Connect to xy
    Comment=Connect to xy via ssh
    Icon=nautilus

Suggestion - even less work:

If you want even less work (=autoconnect) and a graphical user interface, you might want to check out Gigolo . It has the capability of auto-mounting a bookmark, whenever the bookmarked filesystem is present. You might want to check that out.

sudo apt-get install gigolo   # or use the install link above

Run gigolo. There is an option in the preferences that puts it into autostart and another to activate the tray icon. Check both. Then add your bookmark.

Shell way

Another solution would be to put the following line in your crontab (edit /etc/crontab with sudo privileges):

@reboot sshfs user@192.xx.xx.xx.xx:/dir/dir /home/username/mount/xxx

But since Ubuntu's password manager is not present when the command is run you need to use a password-less private/public key pair to authenticate with the ssh server in question (or a similar method of authentication). This would mount it on every reboot.

Yet another solution would be to edit your /etc/fstab (providing your Ubuntu-Version provides that option).
