Red Hat has this:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/device_mapper.html


There is also the kernel documentation tree:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=tree;f=Documentation/device-mapper;hb=HEAD
<http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=tree;f=Documentation/device-mapper;hb=HEAD%20>

I'm curious about what others might suggest.
