Resolve minute openstack error

Hi , I'm getting minute openstack error while running openstack-ansible [login to view URL] from following doc : [login to view URL] -- error was : fatal: [node1_galera_container-1175afe4]: FAILED! => {"changed": false, "msg": "The galera_cluster_name variable does not match what is set in mysql. Check your galera_cluster_name setting in your user_*.yml files in \"/etc/openstack_deploy\" and compare to the current value in \"/etc/mysql/conf.d/[login to view URL]\" on the host, and the \"wsrep_cluster_name\" value set in your running galera cluster. To ignore the cluster state set '-e galera_ignore_cluster_state=true'.\n"} --- You need to resolve this error and until completion you need to work on this openstack installation .
