New Hard Drive

I decided today that I would buy a new HDD for my Mythtv box. Now the transcode issues won't be so bad, at least not space wise (for a while). Right now I'm setting up LVM so that the new HDD and the old one look like one disk. So part of the process is to copy the 150 gigs of data from my old HDD to the new one, then I can get to merging the partitions.
