Hello, I tried to install packstack queens on CentOS 7.4:

packstack --answer-file ~/answers.txt --timeout=900

It fails in the controller.pp step with the following error:

ERROR : Error appeared during Puppet run:
Error: /Stage[main]/Nova::Db::Sync/Exec[nova-db-sync]: Failed to call refresh: Command exceeded timeout

Install on same server (with a fresh centos 7.4 build) of packstack Newton works fine;

Did anybody encounter this and knows the solution?

I increased the timeout as was suggested in some blogs. But this didn't help.

The mentioned logs don't give much more information other than the timeout message. The nova-manage-log ends with:

2018-04-18 14:46:14.669 11393 INFO migrate.versioning.api [req-7ca0238e-0580-4636-9830-efeead00906b - - - - -] 376 -> 377... 2018-04-18 14:46:14.907 11393 INFO migrate.versioning.api [req-7ca0238e-0580-4636-9830-efeead00906b - - - - -] done 2018-04-18 14:46:14.907 11393 INFO migrate.versioning.api [req-7ca0238e-0580-4636-9830-efeead00906b - - - - -] 377 -> 378... 2018-04-18 14:46:15.777 11393 INFO migrate.versioning.api [req-7ca0238e-0580-4636-9830-efeead00906b - - - - -] done 2018-04-18 14:46:16.106 11393 INFO migrate.versioning.api [req-7ca0238e-0580-4636-9830-efeead00906b - - - - -] 215 -> 216...

During the installation the nova-consoleauth service and nova-schedular service are started but throw a lot of mysql (mariadb) errors.

2018-04-18 16:40:34.296 11981 ERROR oslo_service.service ProgrammingError: (pymysql.err.ProgrammingError) (1146, u"Table '' doesn't exist") [SQL: u'SELECT services.created_at AS services_created_at, services.updated_at AS services_updated_at, services.deleted_at AS services_deleted_at, services.deleted AS services_deleted, AS services_id, services.uuid AS services_uuid, AS services_host, services.`binary` AS services_binary, services.topic AS services_topic, services.report_count AS services_report_count, services.disabled AS services_disabled, services.disabled_reason AS services_disabled_reason, services.last_seen_up AS services_last_seen_up, services.forced_down AS services_forced_down, services.version AS services_version \nFROM services \nWHERE services.deleted = %(deleted_1)s AND = %(host_1)s AND services.`binary` = %(binary_1)s \n LIMIT %(param_1)s'] [parameters: {u'host_1': 'hv28', u'param_1': 1, u'deleted_1': 0, u'binary_1': 'nova-consoleauth'}] (Background on this error at:
2018-04-18 16:40:34.296 11981 ERROR oslo_service.service

But I guess this is because the nova-db-sync didn't finish correctly.

Any help is much appreciated.

Thanks, Kees

I did some analyses: nova-manage.log indicated the timeout was after 5 minutes; So the setting on the packstack command line isn't used in the nova db sync puppet manifest.

I did a fresh install of CentOS 7.4 and openstack-packstack as instructed on (

I looked up the manifest, found it in: /usr/share/openstack-puppet/modules/nova/manifests/db/sync.pp in sync.pp I changed $db_sync_timeout = 300 to $db_sync_timeout = 900

and execute 'packstack' again. Now it hits the same issue with neutron db sync.. same solution timeout in the manifest put on 900 and now it is installed

conclusion: has to do with performance / load probably (I/O's?)
