Fixed In Version:	openstack-tripleo-heat-templates-0.8.6-17.el7ost	Doc Type:	Bug Fix
Doc Text:	HAProxy did not use clustercheck to check MariaDB's backends status. This caused HAProxy to forward requests to MariaDB nodes responsive at the TCP check but not in synchronization with the Galera cluster. This fix now uses clustercheck to check MariaDB's backends status. HAProxy now forwards requests to MariaDB nodes correctly.	Story Points:	---
