Issue

After initial deployment using OpenStack Director we still see one controller use a different --wsrep-cluster-address=gcomm address than the others, is this expected?

  • on overcloud-controller-2 we see --wsrep-cluster-address=gcomm:// :
[heat-admin@overcloud-controller-2 ~]$ ps -ef |grep mysql

  • while the other controllers show --wsrep-cluster-address=gcomm://overcloud-controller-0,overcloud-controller-1,overcloud-controller-2 :
