Problem Mounting 2nd Hard Disk

[Carl Lucas]

Just did a clean install of Fedora Core 3.

The "Hardware Browser" shows /dev/hdb....hdb1 Start-1, End-2491; Size: 
19540; Type-LVM Physical Volume.

My problem is I can't get the second hard drive to be mounted.

I create a mount point (/home/carl/drive2).

/sbin/fdisk -l gives:
Disk /dev/hda: 80.0 GB, 80054059008 bytes
255 heads, 63 sectors/track, 9732 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

When I run "mount /dev/hdb1 /home/carl/drive2" I get:
mount: /dev/hdb1 already mounted or /home/carl/drive2 busy

I also tried "mount -t auto /dev/hdb1 /home/carl/drive2" with the same 
message.

Output of lvdisplay:

What am I doing wrong?
