Louis,

     First, Thank you for the reply. The second link you posted is the 
direction I believe I need to take. However It appears it tailored 
towards a HA web server (NGINX).

I want to make sure the direction I go in is approved to work with Samba 
and my DC's. I think this link is where I need to start

https://www.howtoforge.com/setting-up-an-active-active-samba-ctdb-cluster-using-gfs-and-drbd-centos-5.5

My main issue is if I should use CTDB or Pacemaker. I don't know how I 
missed this link as well.

https://wiki.samba.org/index.php/CTDB_and_Clustered_Samba

I'll setup a test environment and see what results I get.
