One other question.

Last time, I created /dev/md0 on /dev/hde1 and /dev/hdg1.  I also created an 
LVM Physical Volume on /dev/md0, and a Volume Group on /dev/md0.  I was 
planning on starting over from scratch to make sure everything is done 
correctly.

Do I need to do anything special to get mdadm and LVM to forget about the 
previous configuration?  I figured that I'd remove /etc/mdadm/mdadm.conf.  I 
also see, for example, /etc/lvm/backup/localvg.  If I plan to call the volume 
group localvg, do I need to remove this file?  Or should I be running some 
sort of LVM command to make it forget about the previous physical and logical 
volumes?
