The naming I was talking about was sort of like a label.  I wanted to 
use test, where I might use say data in real use, but ended up with this:

root@fireball / # df
Filesystem           1K-blocks      Used Available Use% Mounted on
<< SNIP >>
/dev/mapper/sdb--vg-test
                       51606140    184268  48800432   1% /mnt/temp
root@fireball / #

I don't mind the sdb--vg part tho.  I guess that sort of points to what 
all is needed to get to that point.  Might come in handy if I needed to 
remove something tho.  Sort of tells me what is what.

I did try to mount it before putting a file system on it.  I sort of 
missed that part somewhere.  I knew it needed it, just forgot to do it.  
Mount sort of puked on my keyboard to remind me.  lol

Whew !!  Progress.  Oh, someone posted a link to a site that had 
pictures.  That helped a good bit.  It needed more detail tho.  I'm 
going to do some google image searches and see what I can find.

Thanks much.
