Hi all,

I'm trying to install Arch with LVM. I've read the following page:
http://wiki.archlinux.org/index.php/Installing_with_Software_RAID_or_LVM
and tried the following commands:

# lvm pvcreate /dev/sda5
# lvm vgcreate VG /dev/sda5

If I check with "pvscan" and "vgscan" everything seems good. When I
try to create a LV with:
# lvm lvcreate -L 10G -n test VG

I get the following message:
/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?

There is also another error about /dev/mapper/control (don't remember
the correct displayed message). I got this error when booting from the
arch-0.7.1-base CD.

Are there some modules to load for this to work ? Is this a problem
with the 0.7.1 install CD ?

Last question: Is it possible to have the / filesystem resides on a LV ?


Thanks for your help.

Regards,
Gilles.
