Yup,
I forgot to say: Never increase the size of the lv because the
filesystem will not grow, but increase the filesystem and the underlying
lv will grow automatically.
-> use 'chfs -a size=+<addtional blocks> <mount point>'
One nifty trick is to use +1 to increase the filesystem by one pp.
-> 'chfs -a size=+1 /usr' will increase /usr by a couple of megs
