Re: udev lvm permisions

[Geert Geurts <begeert@gmail.com>]

Hello kay,
Thanks for your reply!
Indeed it's about a logical volume I want to mount as a normal user.

I've already had discussion with Michal Soltys,
he sugested to create a rule according to the following:
ACTION!="add|change", GOTO="dm_end"
KERNEL!="dm*", GOTO="dm_end"

PROGRAM="/sbin/dmsetup info -c --noheadings -o uuid -j%M -m%m", 
ENV{DM_UUID}="%c"

ENV{DM_UUID}="LVM-N28qi20mqjyPR150TYivmJzvkn8zzpi2VEhSFspDTiAxn2GLFC7xJ8Lfh12dmGH0", GROUP="users", MODEf0

LABEL="dm_end"


I've created this rule but it applies to the kernel device... /dev/dm-*.
What I need is a rule that changes the ownership
of /dev/mapper/HomeVolume.

Thats where I stand now,
so any suggestions are welcome!

Greetings,
Geert
