What's proven very helpful to figure out these things is to run a test script against md, and just trying all the various possible actions via mdadm or raidtools randomly.
I've done that for m-p, and while it's not pretty, it is _really_ helpful and has found all sorts of weird accounting bugs in the md code (2.4 has many): ftp://ftp.suse.com/pub/people/lmb/md-mp/mp-test.sh - if anyone feels like extending it to include raid5/raid1 etc, that would be cool ;-)
