Docker-thinpool not mounted

Docker Engine General

Hello,

I followed the tutorial here:

By doing:

[root@master ~]# lsblk

sda                         8:0    0  100G  0 disk

    └─docker-thinpool     253:2    0   95G  0 lvm

lrwxrwxrwx 1 root root       7 Oct 25 18:03 docker-thinpool_tmeta -> ../dm-0

However when I do :

 mount |grep devicemapper

I get nothing. Do you know where it should be mounted?
