Good info Eric. Thanks. What if you have already installed Ubuntu
WITHOUT LVM, and later want it. Is is possible to change things after
an install?

I installed ubuntu recently and didn't choose the LVM option. But I
want to add another big harddive soon and would prefer to have the new
drive and the big partition from the existing drive to be seen as a
single disc. A bit of investigation and I found out I probably should
have set it up with LVM originally. Whoops. Is it possible to redo
things now?
