[solved] Udisks won't unmount devices

Lockheed · 2012-05-19 09:44:03

I am using spaceFM to mount/unmount devices. I created
/etc/udev/rules.d/10-my-media-automount.rules
/etc/udev/rules.d/11-mnt-auto-mount.rules

according to this: https://wiki.archlinux.org/index.php/Ud … if_present

but I am not able unmnount. Here is the error I am getting:

Error creating textual authentication agent: Error opening current controlling terminal for the process (`/dev/tty'): No such device or address (polkit-error-quark, 0)
Error unmounting /dev/sdb1: GDBus.Error:org.freedesktop.UDisks2.Error.NotAuthorizedCanObtain: Not authorized to perform operation

Use udev rules OR udisks - not both.

I only added /etc/udev/rules.d/11-mnt-auto-mount.rules trying to solve this issue. It changed nothing.

Was it working at any stage?

No. If it worked, there would be no point in trying to fix it by making changes.

The issue might be related to recent upgrade od udisks to udisks2, but I am not sure about it as it might have started before the upgrade.

OK, firstly remove the irrelevant udev rules.

Now, your devices automount correctly, but fail to umount - right? How are you trying to umount them?

Lockheed · 2012-05-19 18:05:58

in spaceFM, I rightclick on the device, and then UNMOUNT.

Also, now I am getting 'Error: Read-only file system' when I try to copy something on it.

/etc/udev/rules.d/10-my-media-automount.rules

Why do you still have udev rules? I have just installed spacefm, I have no udev rules for removable media, but I do have udisks, and I start my X session correctly i.e. with consolekit. Spacefm calls udisks to automount my devices when I plug them in, and I can unmount them successfully as you describe above i.e. right click -> unmount. This works with both udisks and udisks2.

Lockheed · 2012-05-20 09:26:19

I have this rule because if I remove it, the write speed of USB drives drips by a factor of 10. And I also have consolekit starting my X session.

tomk · 2012-05-20 10:02:29

OK - so udev is mounting the devices with the 'mount' command, and then you're trying to umount them with udisks, via spacefm. That's why it's not working.

That udev article has a set of rules using pmount - spacefm can also use pmount, so that might work better for you.

Lockheed · 2012-05-20 10:18:38

It looks like pmount doesn't support mount parameters, like noatime, which would make it just as slow as udisks.

Do I need to change something in spaceFM to make it use pmount?

I have the same problem with Thunar + Udisks. Udisk mount automaticly the devices but I am not able to umount them through Thunar GUI. I have to umount them by shell.
I don't have any udev rules in /etc/udev/rules.d/
