After reading the docs and searching the archives I'm still a bit confusied on the issue of how to mount the logical volume I've created, upon bootup.
I can use the mount command and that seems to work fine. vgscan detects it on boot.
Currently (and I've just really set up the system) is to issue
mount -t ext3 /dev/video_stor/logvol1 /mnt
then I can cd to /dev/video_stor
while I'm posting here in the dev/video_stor directory I see group and logvol1
