Docker daemon won't start in v0.3.3

I’m running Rancher OS 0.3.3

[rancher@rancher ~]$ docker ps
Cannot connect to the Docker daemon. Is 'docker -d' running on this host?
[rancher@rancher ~]$ sudo docker -d
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) 
INFO[0000] [graphdriver] using prior storage driver "overlay" 
WARN[0000] Your kernel does not support cgroup memory limit: mountpoint for memory not found 
WARN[0000] mountpoint for cpu not found                 
FATA[0000] Error mounting devices cgroup: mountpoint for devices not found

After being left alone for a while the user docker stopped running. I couldn’t find a reason why, but maybe I was looking in the wrong place. I am not familiar with the logging on RancherOS. I checked /var/log/messages but couldn’t find anything that looked useful. Please help me get docker starter again! Thanks

Did you check system-docker to make sure that the docker container is running?

sudo system-docker ps should list the docker container as running.
