Cloning an LVM, Booting It Over USB

[Robert L Cochran]

Here I go again trying to work sideways with my friend LVM. Last night I 
spent several hours cloning my Fedora Core 5 system (residing on a 400 
Gb hard drive) to a Western Digital MyBook Premium Edition ES 500 Gb 
external hard drive. I cloned this drive using the g4u software product 
over USB. There were some rather weird messages on netBSD bootup when it 
tried reading the MyBook drive, but g4u did seem to clone the source 
drive to the MyBook sucessfully. This process took several hours.

Now I would like to test whether I really did clone it successfully. The 
LVM I cloned is

/dev/VolGroup00/LogVol00

I should be able to plug the MyBook into a USB slot on my other machine 
which is running CentOS  4.5. The CentOS installation has this LVM:

/dev/VolGroup25/LogVol24

My theory is I should now be able to boot FC5 over USB from the MyBook 
with no corruption of the LVMs, right? They will be seen as totally 
separate from each other? Is this correct or am I misunderstanding LVM 
in yet another way?

Thanks
