I have read some docs.  I've spent hours combing the Net for the 
answers, without success.

I *had* a working system.  But, I use the LVM commands so rarely, I can 
never repeat what I did (notes or not).

piano:/home/dcorbin# sh -x /etc/init.d/lvm start
+ modprobe lvm
+ modprobe lvm-mod
+ '[' -e /proc/lvm ']'
+ '[' -e /etc/lvmtab ']'
+ '[' -x /sbin/vgscan ']'
+ echo 'Setting up LVM Volume Groups...'
Setting up LVM Volume Groups...
+ /sbin/vgscan --verbose
+ /sbin/vgchange -a y --verbose

piano:/home/dcorbin# mount /data
mount: special device /dev/vg0/data does not exist

The reason you hear "panic" in my typing is the last line. :)

Fundamentally, I'm building a critical data file server.  LVM has caused 
me enough problems and delays, that I'm about ready to bypass it, saying 
it is putting my data at risk.  Feel free to convince me otherwise.

Thanks
