you have to recreate the filesystem that you want to reduce the size

Is that the only way.. I don't think so. There should be some way out.

recomend you test this befor you do it

depending on the space in the fs you can use this command

df filesystem
dev 512block size free mount
/dev/bla 262144 84784 /bla

chfs -a size=252144 /bla

make sure you have free space to reduce the fs by

on the other on you use
chfs -a size=new_size / bla2

this will work if the filesystems are in the same volumegroupe

It can not work in AIX 5.2 and older than AIX 5.2.
do you have test in AIX 5.3 ???
