Public bug reported: The celery cluster is started in upstream:src/provisioningserver/start_cluster_controller.py, called from the upstart script packaging:debian/maas-cluster-controller.maas- cluster-celery.upstart. When all the MAAS' services are stopped (for instance when all the MAAS packages are purged), the celery workers are not properly stopped.
How to recreate: - install the MAAS package - run `ps aux | grep celeryd` to get the list of all the celeryd services. After the synchronization phase, you should see the region workers and the cluster workers (http://paste.ubuntu.com/1253472/ the region workers listen to 'celery' and 'master' while the cluster workers listen to a queue named after a UUID) - remove all the packages with 'sudo apt-get purge maas*' - run `ps aux | grep celeryd`: the cluster workers are still running. ** Affects: maas Importance: Critical Status: Triaged ** Affects: maas (Ubuntu) Importance: Critical Status: Triaged ** Project changed: maas => maas (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to maas in Ubuntu. https://bugs.launchpad.net/bugs/1059453 Title: The celery cluster worker is not properly stopped To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1059453/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
