[rdo-list] Overcloud pacemaker services restart behavior causes downtime

Hi all, I have an overcloud with 3 controller nodes, everything is working fine, the problem is when I reboot one of the controllers. When the node comes online, all the services (nova-api, neutron-server) on the other nodes are also restarted, causing a couple of minutes of downtime until everything is recovered. In the example below I restarted controller2 and I see these messages on controller0. My question is if this is the expected behavior, because in my opinion it shouldn't happen. *Authorization Failed: Service Unavailable (HTTP 503)* *== Glance images ==* *Service Unavailable (HTTP 503)* *== Nova managed services ==* *No handlers could be found for logger "keystoneauth.identity.generic.base"* *ERROR (ServiceUnavailable): Service Unavailable (HTTP 503)* *== Nova networks ==* *No handlers could be found for logger "keystoneauth.identity.generic.base"* *ERROR (ServiceUnavailable): Service Unavailable (HTTP 503)* *== Nova instance flavors ==* *No handlers could be found for logger "keystoneauth.identity.generic.base"* *ERROR (ServiceUnavailable): Service Unavailable (HTTP 503)* *== Nova instances ==* *No handlers could be found for logger "keystoneauth.identity.generic.base"* *ERROR (ServiceUnavailable): Service Unavailable (HTTP 503)* *[root@overcloud-controller-0 ~]# openstack-status * *Broadcast message from systemd-journald(a)overcloud-controller-0.localdomain (Thu 2016-08-04 09:22:31 UTC):* *haproxy[2816]: proxy neutron has no server available!* Thanks, Pedro Sousa
