Hello everybody,

I followed the installation guide for newton on Ubuntu 16.04.1 and got everything working as described except from cinder.

After following the steps described at [1] and starting the services with


> root at storage0:~# service tgt restart
> root at storage0:~# service cinder-volume restart


the cinder-volume.log gets filled with errors and "cinder service-list" on the controller node shows the service of storage0 as "down".


> root at storage0:~# tail -f /var/log/cinder/cinder-volume.log

The second block, starting at 15:45:16.822 repeats all over again and again until the cinder-volume service gets stopped by me.

Can anybody point me into the right direction?

Thank you very much!
