You do not mount a partition of type "Linux LVM" the same way you mount
a partition using a standard Linux file system (e.g. ext2, ext3).
# fdisk -l /dev/hda
Disk /dev/hda: 160.0 GB, 160041885696 bytes

# mount /dev/hda2 /tmp/mnt
mount: /dev/hda2 already mounted or /tmp/mnt busy
First, let's determine the volume group containing the physical volume /dev/hda2.
# pvs

VG Fmt Attr
PSize PFree
/dev/hda2 VolGroup01 lvm2 a- 148.94G 32.00M
/dev/hdb2 VolGroup00 lvm2 a- 114.94G 96.00M
Next, let's list the logical volumes in VolGroup01.
# lvdisplay /dev/VolGroup01
--- Logical volume ---
LV Name /dev/VolGroup01/LogVol00
VG Name VolGroup01
LV

zOQogm-G8I7-a4WC-T7KI-AhWe-Ex3Y-JVzFcR
LV Write Access read/write
LV Status available
# open 0
LV Size 146.97 GB
Current LE 4703

Block device 253:2

Read ahead sectors 0
Block device 253:3
The logical volume I would like to "mount" (in purely the computing-related sense) is /dev/VolGroup01/LogVol00. The other logical volume is a swap partition.
# mount /dev/VolGroup01/LogVol00 /tmp/mnt

I've not much experience with LVM, but I did have a similar problem to
you, so here's how I solved it (Ubuntu 7.04 server).
1. Install lvm2:
sudo apt-get install lvm2
sudo cp -r /lib/lvm-200/ /lib/lvm-0
2. Take note of the LV Name for the volume you want to mount from the
output of the following command (/dev/VolGroup00/LogVol00 in my case):
sudo lvdisplay
3. Run the following commands to mount the logical volume:
sudo modprobe dm-mod
sudo vgchange -ay
sudo mkdir /mnt/old_hd
sudo mount /dev/VolGroup00/LogVol00 /mnt/old_hd
Worked for me!
