Creating an lvm table of groups and then adding the filesystems and OS is not a big job these days and can be done in a few hours. As you most prob already know.
The thing is I have a drive at /dev/sdb designated with a backup of my data.
How would I go about wiping everything and starting fresh from a rescuecd without touching /dev/sdb?
