OK.

No, you can't. Use tar, cpio or rsync.

How do you create an LVM (Logical Volume Manager)? Or do you mean LV 
(Logical Volume)?

I guess 1 and 2 are / and /boot?

Why 3 partitions?

I'm not sure I get what your problem is. If you could tell more about what 
you have (i.e. how are the partitions on those two drives used currently) 
and what you want, it would be much easier to help.

Bye...
