2017-06-11 | Do not create VIP for pacemaker OVN OCF resource | 1 | -29/+7 | ||
The commit with change id [1], added the pacemaker HA support for OVN DB servers. That commit created a new VIP which is really not required. This patch removes the code to create a new ip resource. Instead it expects the pacemaker ip resource (with the ip address in the 'ovn_dbs_vip' parameter and with the name "ip-$ovn_dbs_vip") to be created before ovn_northd class is called, which is the case anyway if 'ovn_dbs_vip' is taken from the ServiceNetMapDefaults (in t-h-t).

2017-06-01 | Pacemaker support for OVN DB servers | 1 | -0/+121 | ||
This patch enables OVN DB servers to be started in master/slave mode in the pacemaker cluster. A virtual IP resource is created first and then the pacemaker OVN OCF resource - "ovn:ovndb-servers" is created. The OVN OCF resource is configured to be colocated with the vip resource. The ovn-controller and Neutron OVN ML2 mechanism driver which depends on OVN DB servers will always connect to the vip address on which the master OVN DB servers listen on. The OVN OCF resource itself takes care of (re)starting ovn-northd service on the master node and we don't have to manage it. When HA is enabled for OVN DB servers, haproxy does not configure the OVN DB servers in its configuration. This patch requires OVS 2.7 in the overcloud.
