udisks: Trying to backup an usb flash memory require manual unmounting

[jlord87]

If you try to backup and usb pen drive with the (nice) preinstalled tool "udisk" the program fails with this error:

"Error opening /dev/sdb: Device or resource busy (udisks-error-quark, 0)"

HOW TO REPRODUCE
1) insert an usb pen drive
2) start udisk
3) select "create image disk" (not really shure about the english text string)
4) you will be prompted for the user password, than the program will exit with the error written above.

HOW TO FIX
1) insert the usb pen drive
2) manual umount it (for me "sudo umount /dev/sdb1")
3) launch udisks (you can obviously umount the drive after launching udisks)
4) start the "create image disk" process
5) it will work.

[Launchpad Janitor (janitor)]

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

[Lesser (j-brouwers)]

Thanks for the workaround!

jlord87, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc4

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

The bug is still here in the daily build.
The only difference is that now I'm not even prompted for the user password (but it may be related to the fact that I'm using a live-usb-pen...)

I'll try to understand how to test with the upstream kernel, but I don't think It's a kernel related problem.

cheers
