To filter a device-mapper device you also have to filter out the
/dev/dm-N device nodes that udev manages. There's also a symlink from
/dev/$VG_NAME/$LV_NAME to the dm-N node (although I think that should be
handled by filtering /dev/dm-N).
I'd be using something like:
[ "r|/dev/dm.*|", "r|/dev/$VG_NAME|", "a|.*|"]
Alternately (and I prefer this for many configurations) you can accept
("a|..|") the device you need for the data VG and reject all other
devices ("r|.*|").

Tags but since you're not currently filtering dm-N nodes I would try
that first.

Bryn.
