Not at all, you can even add another disk and add only a portion of it the the VG before expanding the LV. That is one of the reasons for why it was invented back when disks where small and the need for space for a ever larger growing database was needed.
In fact you can add another physical disk to your VG0, do a PVmove (aka migrate) to move all the extents to the new drive, then lvremove them from the first drive so all the LVM is on the new drive, and then you can play with the partitioning of the old drive with all your data safely on the new drive. And of course you could move it back afterwards :-) But then it may make more sense to do do something like striping ... LVM is very flexible :-) -- A military operation involves deception.
