Description of problem: When halting/rebooting the box I see multiple messages like: Could not delete dm /dev/dm-2: Device or resource busy and: Could not delete dm /dev/dm-0: Device or resource busy These refer to /usr lvm and the underlying Luks crypto device. Of course I fear data-loss. Version-Release number of selected component (if applicable): systemd-44-20.fc17.x86_64 How reproducible: Have PC with fs on lvm2 on crypto on raid; halt the system and see. Actual results: See above Expected results: No such messages, clean stop of MD devices. Additional info:

All other DM devices detach OK, as far as I can see. (home, var, etc) But why does it say '3 left' but prints only dm-0 and dm-2?
It might make sense to suppress these warnings for all block devices which are still referenced from any file system in /proc/self/mountinfo.
*** Bug 756767 has been marked as a duplicate of this bug. ***
Any updates? Any things I can test? Or how I could help?
Why is getting rid of the 'noise' a solution? Why aren't my filesystems in danger?
There's nothing to test yet. Not being able to dismantle a device from which systemd itself runs is the expected behaviour. The filesystem will be unmounted by the initramfs's shutdown script after changing the root pivot.
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17.

Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Loads of bugzilla emails won't help.
