Automount and umount of USB drives not working using udev

mgai7755 · 01-25-2012, 07:21 AM

Hi,

I'm trying to implement the automatic creation of a mount point defined by the volume name of an usb drive when inserted and also the removing of it once unplugged.

Autmounting works as expected. However, unmounting doesn't.

It looks like the lines linked to action:=remove aren't executed at all.

Any idea to help me ?

# uname -a
Linux server 2.6.26-2-amd64 #1 SMP Mon Jun 13 16:29:33 UTC 2011 x86_64 GNU/Linux

Thanks

Here is the contents of my file 76-local.rules

Code:

# /etc/udev/rules.d/local.rules
# /etc/udev/rules.d/76-local.rules

# ADD rule: if we have a valid ID_FS_LABEL_ENC, and it's USB, mkdir and mount

ENV{ID_FS_LABEL_ENC}=="?*",   ACTION=="add",      SUBSYSTEMS=="usb", \
         RUN+="/usr/local/sbin/udev-automounter.sh %k"

# REMOVE rule

ENV{ID_FS_LABEL_ENC}=="?*",   ACTION=="remove",      SUBSYSTEMS=="usb", \
         RUN+="/usr/local/sbin/udev-auto-umounter.sh $env{ID_FS_LABEL_ENC} %k"


# Other way tried, without calling external script. Doesn't work either :

#ACTION=="add", ENV{ID_FS_LABEL_ENC}=="?*", SUBSYSTEMS=="usb", RUN+="/bin/mkdir -p /Volumes/$env{ID_FS_LABEL_ENC}"
#ACTION=="add", ENV{ID_FS_LABEL_ENC}=="?*", SUBSYSTEMS=="usb", RUN+="/bin/mount /dev/$kernel /Volumes/$env{ID_FS_LABEL_ENC}"

#ACTION=="remove", ENV{ID_FS_LABEL_ENC}=="?*", SUBSYSTEMS=="usb", RUN+="/bin/umount /dev/$kernel"
#ACTION=="remove", ENV{ID_FS_LABEL_ENC}=="?*", SUBSYSTEMS=="usb", RUN+="/bin/rmdir  /Volumes/$env{ID_FS_LABEL_ENC}"

Are you using usbmount package?

Nope. Should I ? I'd prefer to fully understand how it works before applying a ready made solution.

No, keep trying?

Wish I could help, but will try a few myself and if I find a solution will let you know.

I personally do not use usb storage so have not thought about the auto mount. I believe some of the later-larger distros may come with it, I will check into that also.
