Docker daemon fails to start

Rancher 1.x

This is more a docker issue than Rancher but I thought I’d ask here. I have a bad host wherew the docker daemon fails to start. systemctl says:

● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)

I’ve restarted the whole host but even that didn’t fix it. Any suggestions where I should look?
