Does the LVM part mean that the partition/disk used to store/run Docker images has to use LVM?

  No, docker sets up its own partition in a loop-mounted sparse file. There is a slight performance tradeoff, but in production you should assume the copy-on-write layer is too slow anyway and use volumes for your performance-critical directories: http://docs.docker.io/en/master/use/working_with_volumes/ http://docs.docker.io/en/master/use/working_with_volumes/ In the future the drivers should support using actual lvm-enabled devices if you have them.
