Jaunty Alpha 5: Usb stick (flash drive) does not pop up on the Gnome desktop

Here is mount for chroot when usb stick is in:

these are the currently used rules, installed as /lib/udev/rules.d/80-ltspfsd.rules by the ltspfsd package

# udev rules for ltspfs, usually installed into:
# /etc/udev/rules.d/ or /lib/udev/rules.d (for newer versions of udev)

# legacy floppy drives:
ACTION=="add", KERNEL=="fd[0-9]", RUN+="ltspfs_entry add %k auto"

# USB floppy drives:
ACTION=="add", SUBSYSTEM=="block", KERNEL!="fd[0-9]", ENV{ID_TYPE}=="floppy", ATTRS{removable}=="1", RUN+="ltspfs_entry add %k auto"

# other drives:
ACTION=="add", SUBSYSTEM=="block", ENV{ID_TYPE}!="floppy", RUN+="ltspfs_entry add %k"

# device removals:
ACTION=="remove", SUBSYSTEM=="block", RUN+="ltspfs_entry remove %k"

can you try running:

udevadm monitor -e

on a client tty while you plug in the usb key so we can see what exactly happens ?

also the output of running "udevadm test" would be intresting to see if there are probs with the rules file itself.

Here is a test - usb stick is in:

root@ltsp200:~# udevadm test
run_command: calling: test
udevadm_test: version 139
syspath parameter missing
root@ltsp200:~#

root@ltsp200:~# udevadm monitor -e

Then I put usb stick in.

Output is as attachment, much longer: udevadm_monitor-e.txt

Best Regards Asmo Koskinen.

oh, sorry that should have been:

udevadm test /dev

(it needs teh devicepath)

I believe this USB stick is /dev/sdb, but

root@ltsp200:~# udevadm test /dev/sdb
run_command: calling: test
udevadm_test: version 139

Then I found this:

So I try this one.
...

Best Regards Asmo Koskinen.

yes, your log shows that udev does the right thing here and calls ltspfs_entry addas it should, probably the environment of udev changed and it doesnt hand over the LOCALDEV variable to ltspfs_entry. (the rules are identical apart from teh comment line)

Here is one more.

root@ltsp200:~# udevadm test /dev/block/8:16

Output is as attachment: udevadm_test_dev-block-8:16.txt

Best Regards Asmo Koskinen.

hmm, lookin at the logs i dont see your partition being used in udev at all, how is that usb key fromatted ?

please attach the output of fdisk -l for the usb key you used for all your tests

it doesnt look like you used the partitioned usb key thats reported in dmesg for any of the testing (note that ltspfs doesnt support unpartitioned usb keys (and never did so))

OK. This is another one usb stick - no pop up icon.

That returns a line with several arguments separated by spaces making the export to fail.

Fixes the issue and the stick correctly gets detected and configured on the thin client.
The signal is then sent to the application server which mounts the stick correctly in /media/<user>/usbdisk-sdc

Though it doesn't display on the user's desktop probably because of something missing in gnome.

Oliver, do you have any idea what we're missing there ? ltspfs seems to work just fine and I can access the content of the usbkey but gnome doesn't seem to detect it ...

I'm having a similar problem in alpha six. I can't access the content (says it doesn't mount) and I can't get it on the desktop.

Something must be wrong with your USB stick or your setup.
I installed alpha-6 from the Alternate CD-Rom, then once installed
booted a thin client and then plugged an USB stick, this one correctly
showed up on the desktop, unplugging it made it disappear as expected.

Please retry with a clean installation of alpha-6 using the LTSP option of the alternate cd-rom.
As after 2 different installations (one i386 and one amd64) I haven't been able to reproduce the issue, I'm marking the bug as incomplete waiting further information or confirmation that the bug is now closed following the fix I uploaded in ltspfs short before alpha-6.

@Stéphane - Well done!!! It works now to me, too. Thank you.

This was fresh install (one nic) with NO updates. I just fixed /etc/ltsp/dhcpd.conf and added a user for a thin client. Nothing else.

Ubuntu Alternate Alpha 6 i386 + HP Mini 2133 as a thin client. I have screenshot here:
http://www.arkki.info/howto/Wiki/LTSP5/Jaunty-A6-i386.png

I think this bug is fixed.

Best Regards Asmo Koskinen.

Good to know it's now fixed.
Closing the bug as fix released.

Asmo, still having problems.

What lines did you add? Thx.

@Bobby - just nothing. It was fresh Alpha 6 installation. As Oliver says, usb stick have to be formatted.

Best Regards Asmo Koskinen.

I just fixed /etc/ltsp/dhcpd.conf and added a user for a thin client. Nothing else.

*googles format USB stick*

that a device you want to use needs to be formatted with any kind of filesystem should be clear indeed ...

the important part is that the device needs to be *partitioned* ...

some windows applications format usb keys directly without creating a partition table, if your device shows up as /dev/sda instead of /dev/sdaX (where X is a number) in the output of dmesg after plugging it in, then it has no partition table. i would recommend using something like gparted to partition and format such an usb key.
