You can certainly resize a logical volume on line, but you also have to
resize the file system in the logical volume, and that depends on the
type of the file system. I recently expanded a reiserfs system in a
logical volume while it was mounted wit no problem. Shrinking is a
different matter.

And to be really picky, a logical volume is not a partition!
