can't mount usb pen drive with hotplug

dori · 06-26-2004, 11:34 AM

I used to be able to have my usb pen drive auto mount when inserted using hotplug and a small script in 9.1, but it's not working with 10. The script in question is located at /etc/hotplug/usb/usb-storage and it looks like:

Code:

dori@darkstar:~$ cat /etc/hotplug/usb/usb-storage
#!/bin/sh
if [ "${ACTION}" = "add" ]; then
    mount -t vfat -o uid=dori /dev/sda1 /mnt/usb128
    cp /var/run/usb/remover $REMOVER
fi

the copy command works, and if I run the mount command by hand after the message in /var/log/messages saying "creating device node sda1", the drive mounts fine and I can use it.

Is there a way to check if the mount error is quitting with some error? What else could be wrong?

thanks,
dori

Try changing the mount command to something like this:

Code:

mount -t vfat -o uid=dori /dev/sda1 /mnt/usb128 2> /tmp/mount.errors

That should dump any mount error messages to /tmp/mount.errors allowing you to see them.

Ah, thank you, yes there was an error: "mount: special device /dev/sda1 does not exist" it appears that the device is getting created after this script is called. I put a date command in the script and it printed Sat Jun 26 11:26:15 CDT 2004, meanwhile in /var/log/messages I see

Code:

Any help on how I might fix this?

One that *might* work, but might not is putting a sleep 5 command before the mount command. That should halt the script for 5 seconds and hopefully give udev enough time to create the device node.

thanks, but no such luck, I think they are called serially

read the man page for MAKDEV

then make the following devices:

brw-r----- 1 root disk 8, 0 1995-04-29 03:33 /dev/sda
brw-r----- 1 root disk 8, 1 1995-04-29 03:33 /dev/sda1
brw-r----- 1 root disk 8, 10 1995-04-29 03:33 /dev/sda10

brw-r----- 1 root disk 8, 12 1995-04-29 03:33 /dev/sda12

That doesn't work, HuMJohn. He's using a 2.6 kernel with udev.

Using the above combination, the /dev directory is created dynamically by the udev daemon as devices are added and removed from the system. Using that script might work temporarily, but probably won't work upon reboot.

dori, if you're interested, have a look at my thread on Project Utopia and Slackware 10. One of the uses of those packages is userland automounting.

HuMJohn · 06-26-2004, 01:45 PM

Thanks, I'll keep this in mind when I add another partition on this system and install 10.0 to use the 2.6.<current> kernel.
