[wellylug] problem mounting debian partition under ubuntu

[Colin Lewis]

having just had Ubuntu installed on Sunday's installfest, I am now 
wanting to access my existing documents from my 2nd HDD that my previous 
Debain install was on.  I was given a set of instructions for using LVM2 
to identify the Debian partition details in order to then mount it for 
access from Ubuntu.  These have not worked however, so any assistance in 
being able to access my second HDD would be appreciated.
The following are the instructions and the results I obtained using them:

1. Install lvm2 using command "$ sudo apt-get install lvm2"
    appeared to be successful

2. Load necessary modules using "$ sudo modprobe dm-mod"
    got result "FATAL: module mod_dm not found"

Persevered to step 3 anyway to scan system for LVM volumes to identify 
the volume group name using "$ sudo vgscan"
    received result "Found volume group "Debian" using metadata type lvm2"

4. Activate the volume using "$ sudo vgchange -ay <volume name>"
    gave result "3 logical volume(s) in volume group "Debian" now active"

5. Find the logical volume that has the root file system using "$ sudo lvs"
    received result:
     LV   VG     Attr   LSize   Origin Snap%  Move Log Copy%  Convert
  home Debian -wi-a- 122.45G                                     
  root Debian -wi-a-  15.00G                                     
  var  Debian -wi-a-  10.00G
    This is where I don't think I got sufficient detail back to proceed 
further

Step 6 was to create a mount point using "$sudo mkdir /mnt/debianhd"
    this appeared to work

last step which I also haven't done was to mount the Debian volume using 
"$ sudo mount /dev/<volume name>/<logical volume> /mnt/debianhd -o ro,user"

Any ideas on how I proceed from here appreciated.
