Since the LVM metadata takes up room, and is stored at the beginning,
I don't see how a partition could be "converted" easily. You could
1) shrink the fs
2) use a special copy to move up the fs enough blocks to make room for
metadata (by starting at the end and working towards the beginning
of the partition).
3) create the PV metadata and allocate the LV without zeroing the
beginning.
However, by that time, you might as well have copied the data. The
only utility would be if there was no room - and it would be highly
dangerous.
