How about going to:

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/

I guess it's obvious it's using different metadata format - since it's based 
on PV/VG/LV.

Internally dmraid shares same kernel code with mdraid.
(unlike mirror which is internal to dm)

There is no detailed doc about everything :) - you can read the open-source.
