The tools read and interpret metadata stored on the physical devices, or 
in the file system. They use this data to instruct the kernel 
device-mapper to create mapped devices that correspond to the volumes 
described in the metadata using the device-mapper ioctl interface (via 
libdevmapper).

See Alasdair's talks for more information on how all the pieces fit 
together:
