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. The target (MyBook) drive is brand new, right out 
of the shipping box. I cloned the source drive using the g4u software 
product over USB. The source drive is actually an LVM system. 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. Here is an edited list of 
the messages issued by g4u:

g4u>disks
wd0 at atabus4 drive 0 <WDC WD400KD-00NAB0>
sd0(umass0:0:0:0) check condition on CDB: 0x00 00 00 00 00 00

[above message repeats several times]
[at this point I turned off power to the MyBook drive]

sd0: drive offline
sd0 detached

[at this point I turned on power to the MyBook drive]

sd0: fabricating a geometry
sd0: 465 Gb, 476940 cyl, 64 head, 32 sec, 512 bytes/sect X 976773168 sectors
g4u> copydisk wd0 sd0

0 0.00 KB/s sd0: fabricating a geometry

[at this point, normal update messages are given e.g. "nnn Gb 20.14 MB/s"


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 both 
g4u and LVM in yet another way?

Thanks
