[kolla][mariadb] failed to start a cluster

Hi, When running kolla-ansible to deploy 3 controller nodes (Ussuri), mariadb on node-1 started fine, but when start mariadb on node-2 and node-3 to join node-1, node-1 became nodor/desync and node-2 and node-3 complained "Member 2.0 (os-control-2) requested state transfer from '*any*', but it is impossible to select State Transfer donor: Resource temporarily unavailable". Ansible failed at "RUNNING HANDLER [mariadb : Wait for MariaDB service port liveness]" when timeout. What could be wrong here? Thanks! Tony
