Nope :-(

I removed all the files /etc/lvm/archive backup etc and the ones
referring to the last LVM setup get recreated on boot.   I'm pretty
sure the LVM info must be on the drive itself somewhere, like software
RAID info.  Then a vgscan etc can pick it up and configure it
automagically on boot etc.

I could just remove LVM, but that's kinda like closing my eyes and
plugging my ears and saying " I Don't See Any LVM - Do You? " :-)

I guess the next step is the LVM users list unless anybody else has ideas?
