[mythtv-users] I Added two 320 GB hard drives to my system, but I cant use them. LVM Problem.

Hello;

Just caught your post and thought I could help.

What your talking about doing is alot easier than you would think it is.
Its not that hard even for a novice. That is why we have LVM. 

What your going to do is GROW the LVM.

The basic steps are:

1. Install the drives and partition them.
2. Then your going to add them one at a time to the volume group.

Here is the LVM Howto. It has examples you can use. Might just head
right to them unless you want an indepth study of LVM.
