[linux-lvm] I'm confused

Hopefully, the following "summary" will make sense.

I'm having trouble reconciling the 436MB   of the "df" with the VG Size 
of vgdisplay.  Obviously something is wrong somewhere.  I KNOW I'm no 
where near using up my 120G drive yet.

For the record, this is a Debian Woody system running a 2.4.19 kernel.

Help.

Thanks
