Well, for example, suppose you run out of disk space. With LVM you can just
add another disk, set it up as an LVM physical volume and then extend your
existing volume group to include the new disk. You can then extend the size of
your existing logical volumes to use the additional space. In effect, your
original disk becomes the sum of the two disks. Much easier than all the
shuffling around of data into different partitions that you'd need to do to
add an additional disk without using LVM.
