I have been trying to get my arms around the USB auto-mount function.
Sorry, no solutions here, just some data that I hope will be useful to
developers. If you spot something I could do better please comment.
I have done all of the configuration steps listed in the on-line
documentation. I would like that to be an install option, default yes.
The table below presents findings for four USB devices. The first three
are flash drives ("thumb" drives). Entries #4 and #5 are separate
partitions on the same external hard drive. Following the table are log
messages associated with device insertion; the numbers coincide with the
table rows. The ufs partition in #5 does not create a separate log entry
even though /dev/da0s1 is created.
Only #1 and #4 operate successfully; the drive mounts automatically and
can be unmounted from the desktop icon.
The documentation on the FreeBSD Gnome web site states that volume
labels must not contain spaces. All of my thumb drives had labels with
spaces or no label at all. I was unable to find a method for changing
the volume label on an msdosfs volume. The tunefs -L command only works
with ufs. I thought glabel might do it, but either it cannot or I did
not stumble upon the right command line. Of course my iMac had no
problem with any of these, and renaming a volume is a snap. Just open
the "get info" dialog. I left #2 with a space for comparison.
I expected my newly assigned volume labels to appear under the desktop
icon. In the table the LAB column shows the assigned volume label, and
DTL shows the label that appears under the desktop icon. I see that #2
and #3 failed to unmount and have desktop labels that are different than
the assigned volume label, and they contain spaces and dots. This could
be significant. Where do those labels come from?
When a device would not unmount by way of the desktop icon I could
unmount it manually (command line umount /media/aName) after doing a
shutdown now. Apparently something in Gnome is hanging onto a file
handle even when I did not have anything open; dropping into single user
mode killed whatever it was.
In addition to these drives I have a Nikon camera that auto-mounted
perfectly in Gnome 2.22 but will not unmount in 2.24. I also have a Sony
PCM-D50 digital recorder that should appear to be a USB drive, but umass
cannot understand it. It works perfectly with Vista and OS X ... :-(
When I plug it in the system freezes, and when I unplug it I get the
famous kernel panic even though the device was never mounted. I have
already been in contact with the author of umass about that.
Is there a reason why my ufs partition does not auto mount? I prefer to
use ufs over FAT32 so that ownership and permissions are not borked. I
should be able to plug it in, wait for the desktop icon, do my backup,
then unmount from the icon.
Why doesn't dropping a disk icon into the trash trigger an unmount
action the way it does in OS X?
I hope someone finds this helpful!
