Your help is much appreciated! Thank you.
The cinder service is running on the controller node and it is using a disk partition not the loopback device, I did change the default configuration during install with PackStack.

I guess both packstack & tripleo will configure this by default if you don't change the configuration. At least tripleo won't configure this loopback device to be activated automatically on boot. An option would be to include lines like the following in /etc/rc.d/rc.local:
