That comes as default with device-mapper - there's no option to turn it off.

Work is progressing on this - some limited mirror features are available 
in 2.01.12:
  Can create new volumes as mirrors, and remove them when not active.
  lvchange -an doesn't work properly yet and must be followed with some 
  dmsetup remove.  Device failure is not handled.  Power cut / reset button 
  is handled OK, keeping the mirror images in sync with each other.
