See these three commits:
d1b652143abc tests: add new test for lvm on md devices
e7bb50880901 scan: enable full md filter when md 1.0 devices are present
de2863739f2e scan: use full md filter when md 1.0 devices are present

(I was wrong earlier; allow_changes_with_duplicate_pvs is not correct in
this case.)
