grub question - migrate to raid lvm

view story

http://forums.fedoraforum.org – The current installed system is a single disk with / fc17 installed on sdg1 and /home on sdg2. This was installed from dvd and operates cleanly. The objective is to migrate this system to raid lvm. The raid pv structure has been built on devices sda - sdf. The vg' s have been created and 2 lv created. The first lv is the / partition and the second the /home. The current boot device is sdg, the new boot device will be sda The new boot partition will be sda1, it has the current /boot contents. The system copy has been restored to the first lv, / partition, and is clean. Assumin (HowTos)
