Why would you mirror a single disk? You need to get another 500Gb hard drive
to mirror with.

Once you get the second drive, you need to make sure LVM is installed. I
think you then need to add your partitions as physical drives and partition
the new drive to match your existing one. Add the new drive partitions as
physical drives and pair them up.

How difficult it is depends on your current set up.
