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)
Active: failed (Result: start-limit) since Thu 2016-10-06 10:24:19 BST; 1min 52s ago

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