Don't feel bad.  The abortion that is the RHEL/CentOS 7 graphical
install interface is far too dumbed-down to be easily usable by anyone
that understands what is going on under the covers.  Oh, the irony.

A quick google brought up the following link that (looking just at the
disk portion) appears to be mostly correct, and should give you the
magic incantation:

<http://www.ictdude.com/howto/install-centos-7-software-raid-lvm/>

The one thing I would point out regarding the above link is that despite
conventional UNIX wisdom, *don't* put /usr on a separate filesystem
in CentOS 7.  <sarcasm>Thank you RedHat</sarcasm>

Flames to /dev/null.
