So then perhaps you could do something if umount's exit status isn't
0... It'll still fail when the device is busy, but won't be stuck in
an infinite loop.
eg.
CODE
while true; do
if [[ -d /media/nameofdongle ]]; then
rsync -switches /media/nameofdongle /some/other/path
error=$(umount -switches /media/nameofdongle 21)
if [ $? != 0 ]; then
echo $(date): Error when un-mounting: $error
/var/log/usb_rsync_errors.log
exit 1
fi
else
sleep 1
fi
done
/CODE
Also, you could use dbus-send to unmount it, it *may* be a bit
cleaner. The command's in the format of dbus-send --system
--print-reply --dest=org.freedesktop.Hal
/org/freedesktop/Hal/devices/volume_uuid_UUIDGOESHERE
org.freedesktop.Hal.Device.Volume.UnMount

The umount would do the trick, assuming nothing else makes the device busy,
THEN you'd get the infinite loop I was worried about. ;)
Hi Jackson, Hi Frode,
as I am not really familiar with this I wanted to try something I already
figured out (with lots of forum reading :-) )
so I created a udev rule: sudo gedit
/etc/udev/rules.d/85-usb_legend.rules
it reads
SUBSYSTEMS==“scsi”,DRIVERS==“sd”,KERNEL==”[0-9]*”,ATTRS{model}==“USB
Flash Disk ”,ATTRS{vendor}==“General
”,RUN+=”/home/seb/bin/legend_sync_mount.sh %k”
in the shell script I then call rsync
#!/bin/sh
rsync -avS -P /media/LEGEND/Documents/sync/TaskCoach/*
/home/seb/sync/TaskCoach
somehow this is 99% similar to another script I set up to fix my external hdd
the only difference is the command called by the script, the scripts location
(not in my home) and the ATTRS attributes
I am puzzled... why it is not working?
As for your solution it seemed to me that it fits not my usage scenario:
- home after work
- plug in and synch
- do something with the files on local hdd
- before unmount sync new/changed filed back to USB
When I get your idea right it will unmount right away!?
Still I would like to test you idea but I am not sure where to place your code.
in a shell script I assume. I have no idea
about the daemon though.
RE umount of busy drive I could use the lazy option.
Cheers,
Sebastian

RE umount of busy drive I could use the lazy option. A couple of things to consider here (if i'm understanding your goals correctly): - Unison is a utility that uses the rsync algorithm to do bi-directional sync. This means that you don't have to manage the bidirectional rsync options yourself, but just run Unison every time either side changes. - You can get GNOME to run a custom command on insertion of different media types using System-Preferences-Removable Drives and Media. I use this to sync my digital camera cards by getting it to run a script which syncs the files (unidirectionally, in this case), then umount the SD card. Then there's no need to run a daemon or poll a driver. A possible down side to this is that you need to be logged in.

Re: script on unmount
That would seem to repeatedly call rsync as long as the folder is there. Probably not what you wanted. Anyone have a better way? :) On Sat, Apr 12, 2008 at 10:57 AM, Jackson Cooper [EMAIL PROTECTED] wrote: Sebastian, The way I'd do it is create a daemon with an infinite loop (I don't know much about udev though) that looks for the folder /media/nameofusbdongle, and if it exists execute the rsync line, then an umount line.
