[CentOS] CentOS 6, Raid 1, and LVM

I'm in the process of rebuilding one of my machines and I've been using 
Raid 1 with LVM on a CentOS 5 OS.  I'm trying to get my ducks in a row to 
move to CentOS 6.  However, I can't seem to locate and on the 
instructions/tutorials that show how to duplicate my Raid 1 LVM 
environment running CentOS 6.

I saw the 'Partionable Raid 1 on CentOS 5 and 6', but it stopped before 
the LVM was introduced.  Can I use those instructions, but add the LVM 
during the graphic installation?  Is it true about some of the warning 
I've been reading about issues with this environment?
 
TIA,
Gene Poole
