What do I need to do to access my LVM partition under kernel2.6.13archck ?
I've followed the wiki at: http://wiki.archlinux.org/index.php/Udev but everytime I reboot using the 2.6.13 kernel, it complains about /dev/vg1 not being a valid block device.
I guess its something to do with udev rules?
yeah, I remember this. It was driving me nuts until I found one magical line in /etc/rc.conf. Open it up and search for lvm...
EDIT: Alright. After rereading your post, I noticed that this might not be your problem at all... but maybe it is...
