I think we need to look at the contents of /etc/sysconfig/docker-storage-setup. What is in that file? Did you just install the latest? Did you do any upgrades since then? I just updated a node from 7.1711 to 7.1803 and I see an issue where docker won't come up because of a similar problem (i.e. issue with docker-storage-setup service), but I also see another problem. I documented the issues in https://pagure.io/atomic-wg/issue/498 Dusty
