i asked a similar question a couple weeks ago but got no response.
this is how i did it

umount /dev/path/to/lv
e2fsadm -L 20G /dev/path/to/lv

additionally i wanted to remove a disk from the LV so:

pvmove /dev/hdx
vgreduce /dev/hdx

i am by no means an lvm expert.  i joined the list to get help with my
situation, and have been hanging out. maybe this will get you pointed in
the right direction.

good luck
