Sorry, Gene -- I fear you have it backwards. The LVM stuff happens *below*
the file system: you first add physical volumes (PV) to a volume group
(think a "pool"). From that you "cut out" logical volumes (LV), which
are just bunches of blocks which show themselves to the OS as "block
devices" (/dev/mapper/foo, typically).
On top of that you can put a file system (as you can on any "bunch of blocks",
i.e. a block device or file).
Perhaps having a mental model the docs make more sense.
