Is it right to see LVM as software to combine several HD's? Does it
have any use with respect to a single 1.5TB HD?
Yes. At some point, if you run out of space on that device, simple add
another disk to your existing single-disk LV (logical volume) and
presto, more space!!
Also, you can resize volumes dynamically very easily, thanks to the extra
abstraction layer provided by physical and logical extents.
I'd recommend only doing that on /home, /data, ... so that if something
goes wrong, you can still boot up and log in as root.
Traditionally, you would only put /boot out of the volume group, but now
that grub2 has fine support for LVM, I don't see any reason to exclude any
volume from the group.
