Hey Chris thanks for the help, that is essentialy what i had done, the
directory was mounted, but i had mounted it on a new partition directory
named "/www" and then had changed my "/etc/httpd/conf/httpd.conf"  to
reflect the new document root settings, i ran the "restorecon -R -v
/www" and then reloaded the HTTPD server, the error i received was that
none of my new directory structure existed. I then tried as you posted, 
to mount my new MD0 device in its the position "/var/www" , "mount -t
ext3 /dev/md0 /var/www" and ran "restorecon -R -v /var/www"  this seems
to work as Apache loaded fine, where as me labeling  "/dev/md0" as
"/www" and running "restorecon -R -v /www" didn't seem work for
me. I
know by default of course Apache has its core directory stored in "/var/www"
