7.25 2017 I've installed the newest devstack on Ubuntu17.04. The version of Openstack is Ocata. After rebooting the Ubuntu, I find it unable to start the OpenStack service.
After searching lots of pages, most of them are outdated. In my devstack direcionary, no rejoin-stack.sh, no screen-stackrc.
So, how can I restart the devstack without ./unstack.sh and then ./stack?
