umounting detatchable media in FC5

Hi,

A  USB issue with FC5 (fresh install on a 64 bit AMD). Logged in as a 
regular user, using the KDE desktop. Connect a USB drive. It automounts 
and I get the nice icon on the desktop. From the icon I can "safely 
remove" or (after "safely removing") "mount" the drive.

Can't do either from the command line. umount tells me I'm not root, and 
mount fails because the device isn't listed anywhere I know of.

Yes, I could probably spend 4 hours reading 
http://www.reactivated.net/writing_udev_rules.html, and then another 
hour reading up on sysf, but geez, it shouldn't take all day and mastery 
of two subsystems to learn how to (u)mount a drive from the command 
line, especially when the disto includes GUI commands for the same action!

Can you kindly give the ½ hour tutorial version? Here's my very vauge 
and probably wrong outline, posed as questions:

do I add a line for each detatchable media to my fstab file? Could you 
give me an example line for a thumbdrive that automounts as 
"/media/CORSAIR"?

Could you give me an example udev rule that would put this drive where 
fstab says it should go?

Where do I put this udev rule? Does it go in its own file, or is there a 
system-wide file?

It looks like I have to run udevstart after changing the rules. Correct?

Thanks,

+glenn

Try using gnome-umount.  There's no manpage.  Use gnome-mount -? for
options.

Hello, Glenn
I can't give you an example of a udev rule.  But I can tell you that I
use the KDE desktop as well, and that I had the same problem that you
are having now when I installed FC5.  What I have done is to add the
following lines to my /etc/fstab:
   /dev/scd0	/media/cdrecorder	udf,iso9660	auto,user,kudzu,exec,ro 0 0
#/dev/scd1	/media/cdrecorder	udf,iso9660	auto,user,kudzu,exec,ro 0 0
   /dev/hdd	/media/cdrom		udf,iso9660 	auto,user,kudzu,exec,ro 0 0
#/dev/sdb1	/media/usbdisk	auto			auto,user 0 0
   /dev/sda1	/media/usbdisk	auto			auto,user 0 0

You can ignore the lines that are commented out.  For some reason, I
have an additional issue where /dev/scd0 will become /dev/scd1,
and /dev/sda1 will become /dev/sdb1 (but this hasn't happened for a
while :))  (My cdrecorder of the external USB2.0 variety.)

In response to your problem, I just made it even more user-friendly for
myself.  Do as follows:
1. Put lines in /etc/fstab for any devices that you may want to mount
as a regular user, using the examples from my own /etc/fstab
2. In your "~/.kde/Autostart" directory, create a symlink to
"/usr/bin/autorun"
3. In your "~/.bashrc" put a line like this:
alias autorun="/usr/bin/autorun -d"
This will force "autorun" to run as a daemon after you login to KDE.
4. Log out, and then log back in.

I just tried logging out and then logging back in WITH a data CDROM in
my cdrecorder.  When I logged in, that CDROM mounted with no
interference from me :)  I then opened up a terminal and ran
"umount /media/cdrecorder" as a regular user.  Worked perfectly.  Word
of caution, though: I left the CDROM in the drive as I continued typing
this, and it remounted itself :)

For whatever reason, my flash drive does not automount on login.  Not a
huge deal, since I can now run "mount /media/usbdisk" as a regular
user.  Also, using the MountMan feature on the Krusader file manager:
http://krusader.sourceforge.net/
That works great as well (again, as a regular user)

If this does not work as seamlessly for you as it does for me, let me
know and maybe I can help you further.
