I even switched the drives around, e.g. making primary master secondary slave and so on, and to my suprise it just worked as if I didn't do anything. So I don't understand why there are troubles moving from lvm1 with devfs to lvm without devfs. I even used KNOPPIX in one of the systems, which has devfs disabled AFAIK, and still had no problems getting access on my data besides doing manual "vgscan ; vgchange -a y" and mounting. Just my 0,02 Euro. Greetings Frank Benkstein.
