Hi all, upgradig from pike to queens I got a lot of errors in nova-api.log: upgrade pike to queens get `xxx DBConnectionError SELECT 1` My issue is the same reported at: https://bugs.launchpad.net/oslo.db/+bug/1774544 The difference is that I am using centos 7. I am also using haproxy to balancing galera cluster . Modifying nova.conf ans using end exluding haproxu specifying only a galera cluster member the problem disappears. Please, any help ?
