This is about version 7 ;) furthermore, which wiki article are you referring to? the search yields many results like: http://wiki.centos.org/HowTos/CentOS5ConvertToRAID?highlight=%28raid%29 which might be not what you want, depending on what you want. I'm no fan of copy and paste tutorials if they are not used just for very specific use cases. and just using a centos 5 tutorial on centos 7 seems not to be the best way to start things.
