nautilus cannot unmount encfs and sshfs disks

[Balau]

Binary package hint: nautilus

Appears on Ubuntu 9.04 Desktop x86.
nautilus 1:2.26.2-0ubuntu2

To reproduce the problem:

- Run the commands:
$ sudo apt-get install encfs
$ mkdir ~/d_enc
$ mkdir ~/d
$ encfs ~/d_enc ~/d
The last command creates the encfs disk in d_enc and mounts d.

- A disk called "d" appears on the desktop.
- Right-click on the disk "d" and select "Unmount Volume"
- A message window opens with title "Unable to unmount d" and text "umount: /home/username/d is not in the fstab (and you are not root)" and presents an OK button.

The same happens on disks mounted through sshfs.

Nautilus should understand that the disks can be unmounted with "fusermount -u $dir", or it should not display "Unmount Volume" or even show the disks on the desktop at all.

does it works fine if you mount them with gvfs-mount ?

[Balau (balau82)]

For ssh disks: Yes.
I can mount the remote disk using:
$ gvfs-mount sftp://${SERVER}/${PATH}
...or using "Connect to Server..." dialog and Service Type: SSH. The effect is the same. In these ways, it is not using sshfs. A folder appears on the desktop, instead of a disk. If I unmount this folder by right-clicking on it and selecting "Unmount Volume", it works just fine and the folder disappears. This functionality can easily replace sshfs.

For encfs disks:
I don't know how to mount an encfs folder with gvfs-mount, and the command gvfs-mount lacks its man page.

could you try if that's still an issue in karmic or lucid?

[Balau (balau82)]

Ubuntu Karmic behaves in the same way, both for encfs and for sshfs. I don't have Lucid installed.
At this point I don't know if it can be considered a bug or a feature request.
What I know is that these protocols (both based on FUSE) seem to be managed by the desktop environment because an icon appears on the desktop (and also in nautilus "Places") after mount, but trying to unmount the disk from that icon results in the error message.

does using "udisks --unmount <device>" on the device works?

[Balau (balau82)]

udisks is only available on Lucid, so I installed Lucid RC in QEMU.
I tried the following:

for encfs:
$ mkdir /home/francesco/d_enc
$ mkdir /home/francesco/d
$ encfs /home/francesco/d_enc /home/francesco/d # a new disk icon
called "d" appears on the desktop
$ udisks --unmount /home/francesco/d
Device file /home/francesco/d is not a block device: resource
temporarily unavailable
$ udisks --unmount /home/francesco/d_enc
Device file /home/francesco/d is not a block device: resource
temporarily unavailable
$ sudo udisks --unmount /home/francesco/d
Cannot stat device file /home/francesco/d: Permission denied

for sshfs
$ mkdir /home/francesco/s
$ sshfs user@host:/path /home/francesco/s # a new disk icon called "s"
appears on the desktop
$ udisks --unmount /home/francesco/s
Device file /home/francesco/s is not a block device: resource
temporarily unavailable
$ sudo udisks --unmount /home/francesco/d
Cannot stat device file /home/francesco/s: Permission denied
