How to apply docker devicemapper storage driver in ubuntu:14

The default docker storage driver(docker version:1.11.2) in ubuntu:14 is aufs. I want to change it to the devicemapper storage driver. I configure this following this page on Docker/doc: #Configure Docker with devicemapper#

https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/  

But the configure commands in the page is not based on ubuntu. There are some steps I can not configure. For example,when I try to create a thinpool, I can not find the “–wipesignatures” in the following line.

$ lvcreate --wipesignatures y -n thinpool docker -l 95%VG

I have tried this for days.If you ever configured this, that will help me a lot. Thank you.
