[gentoo-user] Fwd: Set mount point of external drive with udev rules

[gentoo-user] Fwd: Set mount point of external drive with udev rules

[mikey]

Hi I have an external drive that I would like mounted with HAL, so
that it doesn't mount on boot (which takes ages for it to spin up) and
so that I can add and remove it easily.

As I understand it udev rules are the way of doing this.

I have spent quite a while reading about these and understand roughly
what i want but I can't get any response from the changes I have made
(and have had to guess about things I don't want to guess about) so
how do I set them:

My guess to see if I can select the right drive
/etc/udev/rules.d/10-local.rules:

SUBSYSTEMS=="block", ATTRS{serial}=="2HBEQTN2", KERNEL=="sd?",
NAME="%k", SYMLINK+="external", GROUP="storage"
SUBSYSTEMS=="scsi", ATTRS{serial}=="2HBEQTN2",KERNEL=="sd?1",
SYMLINK+="external", GROUP="storage"


Produces no /dev/external when I restart HALD

This is the info about my drive:

$ /sbin/udevadm info -a -p $(/sbin/udevadm info -q path -n /dev/sdb)

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

I recently did this with a bit more generic rule, this works for me:

#LaCie 2TB USB hard drive
SUBSYSTEMS=="usb", ATTRS{manufacturer}=="LaCie",
ATTRS{product}=="LaCie Hard Disk", NAME{all_partitions}="lacie",
SYMLINK="lacie"

It will create /dev/lacie1 for the first partition, /dev/lacie2 for second, etc.

You need the output for /dev/sdb1.

Re: [gentoo-user] Fwd: Set mount point of external drive with udev rules

[mikey]

I don't blame people for not wanting to touch this with a barge pole,
it's a complete nightmare. I have had success to a degree in that I
created a .fdi file which gives my device a pseudo label of music so
it now gets mounted as /media/music and I found a -rather basic -
script to mount devices via HAL and DBUS
(http://www.datapax.com.au/apps/halmount/), so if I run my script on
boot then my drive starts up mounted as a unique location. This is
however a hack.

I have still been unable to make any kind of match using UDEV rules on
my system and would like to know how or where I'm going wrong.

The {serial} in your rule does not contain the trailing spaces that
are in the actual udevadm output. Maybe that's the reason.

udev rules should match without trailing spaces,although things don't
always work as they should :(

From <http://www.reactivated.net/writing_udev_rules.html>:

  ... while it is legal to combine the attributes from the device in
  question and a single parent device, you cannot mix-and-match
  attributes from multiple parent devices - your rule will not work.

From the output of `udevadm info` you posted later, the parent device
with ATTRS{serial}=="2HBEQTN2" has SUBSYSTEMS=="usb", not "block"
or "scsi".  That's the only problem I noticed, but I didn't look too
hard after seeing that one.
