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

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.
