I'd say you've stuffed it all. With a new install, you should need to do
anything except provide a mount pount in /etc/fstab. The lvcreate/pvcreate
etc is not necessary. Basically you've gone and repartitioned your drive
(not exactly, but close)
All that is needed something like
# LVM initialization, take 2 (it could be on top of RAID)
if [ -e /proc/lvm -a -x /sbin/vgchange -a -f /etc/lvmtab ]; then
action $"Setting up Logical Volume Management:" /sbin/vgscan &&
/sbin/vgchange -a y
This is from RH7.3 so it's definitely in FC3 (and FC4 since I use FC4).
