I currently have my hard drives set up like this:



I want to add two 500 GB hard drives to the setup so that it will look like this:



How would I go about doing this without losing any data on either and still allow it to be easily upgradeable? I haven't found a guide to doing this particular setup with LVM yet. Also, the 320 GB HD's are currently using xfs (if that matters). Thank for any help.

I followed this under Manual LVM setup and it worked perfectly.

I originally intsalled myth on a SATA 250GB drive, and then added three more 250GB drives using the above link.

It worked great.
