Error starting up serviced 1.1.1

Hi everyone,

I've run into an issue installing resource manager 5.1.1. Wewere running 5.0 but ran out of space, when trying to get the service back up and running after adding space, we ran into the issue of docker complaining about UUID of the data stores being out. In the end I opted to just do a fresh install of 5.1.1 instead of going through the hassle of trying to get the 5.0 machine upgraded.

Now On a fresh isntall of 5.1.1 I'm getting the following when I attempt to start serviced:

Unable to validate server options: Use of devicemapper loop back device is not allowed unless --allow-loop-back=true

Here's the output of docker info:

Any one have any ideas

rm -rf /opt/serviced/var/volumes/.devicemapper
rm -rf /var/lib/docker/*

systemctl restart docker
systemctl restart serviced
