Hi Tim and Alex, I see congress recently added the HA functionality, and I was looking at the tempest test code to understand how to start a replica. I created a new congress.conf file with the different "bind_port" and set the "datasource_sync_period" value to 5. However, I got the errors below when I try to bring up the replica:
to start the replica: cd /opt/stack/congress && python /usr/local/bin/congress-server --config-file /tmp/congress.conf & echo $! >/tmp/congress.pid; fg || echo "congress failed to start" | tee "/tmp/congress.failure" 2015-07-27 14:56:33.592 TRACE congress.service Traceback (most recent call last): 2015-07-27 14:56:33.592 TRACE congress.service File "/opt/stack/congress/congress/service.py", line 32, in wrapper 2015-07-27 14:56:33.592 TRACE congress.service return f(*args, **kw) 2015-07-27 14:56:33.592 TRACE congress.service File "/opt/stack/congress/congress/service.py", line 50, in congress_app_factory 2015-07-27 14:56:33.592 TRACE congress.service cage = harness.create(root_path, data_path) 2015-07-27 14:56:33.592 TRACE congress.service File "/opt/stack/congress/congress/harness.py", line 151, in create 2015-07-27 14:56:33.592 TRACE congress.service for policy in db_policy_rules.get_policies(): 2015-07-27 14:56:33.592 TRACE congress.service File "/opt/stack/congress/congress/db/db_policy_rules.py", line 84, in get_policies 2015-07-27 14:56:33.592 TRACE congress.service session = session or db.get_session() 2015-07-27 14:56:33.592 TRACE congress.service File "/opt/stack/congress/congress/db/api.py", line 40, in get_session 2015-07-27 14:56:33.592 TRACE congress.service facade = _create_facade_lazily() 2015-07-27 14:56:33.592 TRACE congress.service File "/opt/stack/congress/congress/db/api.py", line 27, in _create_facade_lazily 2015-07-27 14:56:33.592 TRACE congress.service _FACADE = session.EngineFacade.from_config(cfg.CONF, sqlite_fk=True) 2015-07-27 14:56:33.592 TRACE congress.service File "/usr/local/lib/python2.7/dist-packages/oslo_db/sqlalchemy/enginefacade.py", lin ..... 2015-07-27 14:56:33.592 TRACE congress.service File "/usr/local/lib/python2.7/dist-packages/pymysql/err.py", line 112, in _check_mysql_exception 2015-07-27 14:56:33.592 TRACE congress.service raise errorclass(errno, errorvalue) 2015-07-27 14:56:33.592 TRACE congress.service OperationalError: (pymysql.err.OperationalError) (1040, u'Too many connections') I got the same error when running the tempest test as well. Any idea ? Thanks, Hong
