How to restart a specific openstack-service installed using devstack?
Rejoin stack screen as
./rejoin-stack.sh
and move to the specified service page using ctrl+a+", then type the number of the screen you need to go.
Hit 9 and then ctrl+C. The service would be stopped now. Re-run the following devstack command to start the service: (e.g for nova-network) cd /opt/stack/nova && /usr/bin/nova-network --config /etc/nova/nova.conf || echo "n-net failed to start" | tee "/opt/stack/stack/n-net.failure"
Hit Ctrl+d to detach from the stack screen.
