Yes..I do have the space to do that one by one & that was exactly the
question I was asking.

Problem is that I have never used LVM before and the new systems where
I have installed WBEL4 have installed LVM automatically when
autopartition is used.

Can you/someone please give me pointers to some materials/web
resources which show step by step way of doing it. LVM howto takes a
bit time digesting and testing...wanted something that straight digs
into doing it command by command...testing it out on a spare system
and start on the machine I need ON....and then sink my teeth into the
howto to learn the insides.

With best regards.
Sanjay.
