The mapping table contains all of the possible options you should need.  The options are listed in linux/Documentation/device-mapper/dm-raid.txt.

I have thought that it might also be useful to notify the kernel of a drive failure (or a drive returning to life) without having to load a new mapping table.  This could be done through the DM message interface.  If you find that this is a necessary thing, we could talk about that too.
