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

[Dave Oxley]

This is a bit off-topic, but it may be worth looking at a raid solution
as well. It took me weeks to copy my DVD collection and I started to
worry about a disk going down and having to do it all over again!
Backing up 1.5Tb is not an easy prospect. I got myself an areca raid 
controller and a hot-pluggable sata backplane. With 3 750Gb disks set up
as raid 5 I now have 1.5Tb of expandable storage and if a single disk
goes down, I'm still ok! Not as good as proper backups, but I feel a bit
happier.

Dave.
