You would start looking in mdadm.h at the "struct superswitch". This lists a both of inter points for the metadata module. The intent of some should be obvious from the name. Others come with a little bit of documentation. I'd be very happy to flesh this documentation out now that the interface has (hopefully) stablised. If you could help by asking focussed questions that I could answer by improving the comments, that would be a big help. > > Or is the only documentation the source code to mdadm? The final arbiter is certainly the source code, and I often have to check the actual call patterns myself to be sure. But I think it is time to start tidying this up.
