Nautilus can't properly unmount FUSE file systems

[Eivind Kjørstad]

Normal users can create and mount fuser-filesystems, such as encfs. By doing "encfs ~/somedir ~/some-other-dir", these filesystems correctly show up on the desktop as mounted filesystems.

However, if you right-click and select "unmount" you get a error-message saying you cannot unmount the filesystem, because it does not appear in fstab, and you are not root.

This is factually incorrect -- you *can* unmount the filesystem, assuming you're the user who mounted it in the first place, by using the command "fusermount -u directoryname"

Nautilus should recognize this kind of filesystem and call the apropriate command for unmounting, so that it would work, instead of falsely claiming that you cannot unount the filesystem.

Tested with encfs, likely to affect other similar filesystems like sshfs.

Affects both Hardy and Intrepid

Update: Tested with the latest jaunty-alpha, still present.

Confirmed as having this problem on Intrepid. Would seem to be simple to implement as the mount command sees the mount point and recognizes it as an fuse mounted folder.

[Andrew (andrew-rw-robinson)]

Work-around:

install nautilus-actions
Create a new action "Unmount fuse" with Path:
/bin/fusermount
And Parameters:
-u %M

Under conditions, select "Only folders"

Not as good as the unmount, but helpful if you want a UI approach

Thank you for helping with making Ubuntu better by reporting this bug. This is actually a bug in Nautilus itself and not in Nautilus Actions, which is an extra that isn't even installed on most systems. I'm reporting this upstream.

I've marked #417743 as a duplicate of this bug. It does have some helpful information, for example on reproducing this error.

Note that this bug still exists in Lucid.

Hey. Is this bug going to be fixed anytime soon?

Right now, when I mount something with sshfs (fuse), it shows up in the "Devices" section of nautilus. But when I try to unmount it by pressing the eject button, I get this error: "mount: ... is not in the fstab (and you are not root)".

This one would be great for another "one hundred papercuts". Long standing, annoying little bug.

[Danielle Foré (danrabbit)]

Marking as "invalid" for Files since it's been marked upstream as being a bug in GVFS itself

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Aravind R (araviaravi)]

This happenns with me too. When mounnt smbd / unmount smmbd.

[Andy Holmes (andyholmes)]

There's an upstream bug for this[1], but no activity since 2012-08-21.

According to https://github.com/karelzak/util-linux/pull/705, this issue seems to have been fixed natively in mount/libmount1 from util-linux (since version 2.34). So it should work with Ubuntu 20.04 LTS (focal fossal) and newer.
