There is no KERNEL=="device-mapper" for your volume, it's just a block device named "dm*". Also, we should not change kernel device names, if not needed, but create symlinks to it. And we should not overwrite /dev/mapper/ links as long as libdevmapper is not aware of udev poking in its "private" files. Changes to /dev need to be serialized and atomic in its operations, and two processes touching the same files just asks for trouble.
