Most likely you built your LVM/dm userspace without proper udev support, or left support in there that creates device nodes on its own. Nowadays with devtmpfs device nodes are created exclusively by the kernel and userspace should never create a single device node. If your LVM/DM tools still do, then they have been built with incorrect build-time settings. Note that LVM/DM issues are probably better discussed at the LVM/DM mls than here...
