This is a little sparse on details, but you may have the problem I hit,
which was not having set up lvm.conf to exclude the underlying devices.
LVM2 (at least its current iteration) doesn't automagically exclude
devices that underly an MD set. 

You might try setting a filter in lvm.conf that excludes everything but
MD devices, e.g.:

filter = [ "a|^/dev/md|", "r|.*|" ]

Not sure if this works at all with LVM1, though.

Of course, I could be completely wrong here, and your problem is
something else entirely...
