If udisks-daemon is started (say, by the GNOME desktop), any attempt to mount a file system on a floppy drive by any user with the 'mount' command is thwarted. According to strace, the mount itself succeeds, but then 'udisks-daemon' immediately unmounts it afterwards! This problem does not occur with sys-fs/udisks-1.0.1-r1 so I think the 'udisks-1.0.1-no-floppy.patch' applied by -r2 is to blame. A workaround is to use the udisks command to mount the floppy; e.g.: udisks --mount /dev/fd0 # assuming /dev/fd0 is in /etc/fstab Reproducible: Always Steps to Reproduce: 1. Make sure udisks-daemon from udisks-1.0.1-r2 is running - on my system it is started by GNOME or gdm (not sure which) 2. Try to mount a floppy with a file system - e.g. mount -t vfat /dev/fd0 /mnt/floppy 3. Run 'mount' and see that the floppy is no longer mounted! Actual Results: The floppy is automatically unmounted as soon as you mount it. Expected Results: Floppy should remain mounted.

Created attachment 248163 [details] Partial strace from running /usr/libexec/udisks-daemon There were two udisks-daemon processes running, one is a child of the other. This strace is from the parent (process 2306) showing what happens when the 'mount' command is used to mount the floppy. The interesting part is where it (falsely) decides there is no media in the drive and causes it to be forcibly unmounted (around line 108 of the trace). The reason it decided there was no media in the drive is because of the "no_floppy" patch applied to the sources.
I filed a bug report upstream: https://bugs.freedesktop.org/show_bug.cgi?id=30283
1.0.2 is tree now, and it includes the patch that caused the problem in the first place... upstream bug still open :/
Wait, you have floppy drive in /etc/fstab? It shouldn't be there if handled by udisks (udev). I guess this would be "INVALID" then...
well, it still isn't nice to crash, right ?

Trying to mount the floppy by opening the 'Floppy Drive' icon in the 'computer:///' (Computer) location in nautilus still fails with the error 'No medium in the drive', which I think is due to same bug, or at least a very similar bug.
I have the same problem. Also you'll get an error message trying to unmount floppy: # udisks --unmount /dev/fd0 Unmount failed: Cannot unmount because file system on device is busy You must kill udisks-daemon to unmount it.
http://bugs.freedesktop.org/show_bug.cgi?id=30283#c26 Solution: Use sys-fs/udisks:2 instead of sys-fs/udisks:0
(In reply to comment #8) > http://bugs.freedesktop.org/show_bug.cgi?id=30283#c26 > > Solution: Use sys-fs/udisks:2 instead of sys-fs/udisks:0 I suppose that means waiting for Gentoo to update Gnome or for a udisks2 patch to be developed for gnome-base/libgdu-3.0.2.

I currently have the 'gdu' local USE flag set for gnome-base/gvfs in my /etc/portage/package.use but it probably isn't needed any more as gvfs also has the 'udisks' local USE flag set in my system's make.profile cascade.
Use USE="udev udisks" instead of USE="udev gdu" for gnome-base/gvfs. The USE="udev udisks" is already the default for ~arch >=gnome-base/gvfs-1.12.3-r1. And will move to stable soon as we are ready to stabilize newer udev, messing with udev-171-r* is a waste of time as so so many fixes have landed to >=udev-192. So anyone suffering this problem: Change gvfs to use UDisks2 and drop any legacy programs still using UDisks1 as it's really going away...
*** Bug 453744 has been marked as a duplicate of this bug. ***
while sys-fs/udisks:2 is the real fix, I've now also added +*udisks-1.0.4-r5 (25 Jan 2013) + + 25 Jan 2013; Samuli Suominen <ssuominen@gentoo.org> +udisks-1.0.4-r5.ebuild, + +files/udisks-1.0.4-revert-floppy.patch: + Revert part of upstream commit that prevented UDisks1 from polling for floppy + drive so often but while at it broke the actual mounting of floppies wrt + #338185 by Ian Abbott and others luckily udisks:2 is in stable now too (at least for amd64, others pending)
Updated udisks and floppies now work. Thanks for all your efforts. It's not clear if the patch is the fix, since udiscs2 is now stable for x86, and the update brought in both: > equery list udisks * Searching for udisks ... [IP-] [ ] sys-fs/udisks-1.0.4-r5:0 [IP-] [ ] sys-fs/udisks-2.0.91:2
