[ale] Laptop HD Mounting to desktop solution...

[Brian J. Dowd]

This worked.... For the googled archives :-)
(The disk came from a laptop with Ubuntu and is attached to a desktop 
computer running Fedora Core 5)

/usr/sbin/lvmdiskscan shows that the attached laptop HD /dev/hdc5 is 
56GB on an LVM physical volume
(FWIW /sbin/fdisk shows that it starts at 1 and ends at 7296 for 5836081 
blocks)
    Importantly the filetype ID is 8e which stands for "Linux LVM"
You can't do a mount -t ext3 /dev/hdc5 for two reasons:
    1) It's an LVM not an ext3 filesystem and
    2) It's not referred to a /dev/hdc5
You must run /usr/sbin/lvdisplay which shows that LVName=/dev/Ubuntu/root
Therefore the correct way to mount this laptop disk onto the desktop 
system is
# mount /dev/Ubuntu/root  /mnt

Hope this helps the next person...
