Ussuri Series Release Notes

13.0.0

New Features

  • A new field named service_status_updated is added to the instance API response which e.g. could be used to validate if the instance ‘HEALTHY’ status is stale or not

  • A new database service status HEALTHY is introduced to indicate that the service is responsive. HEALTHY is the final status after ACTIVE.

  • Admin user can delete datastore if there are no instances or backups associated.

  • Add XFS disk format for database data volume, cloud admin can config ‘ext3’, ‘ext4’ or ‘xfs’ in volume_fstype option.

Upgrade Notes

  • Python 2.7 support has been dropped. The last release of Trove to support Python 2.7 was OpenStack Train. The minimum version of Python now supported by Trove is Python 3.6.

  • Trove is now using admin clients by default to communicate with Nova, Cinder, Neutron and Glance. Deployers want to stick to the old clients need to explicitly config the following options:

    • remote_nova_client

    • remote_cinder_client

    • remote_neutron_client

    • remote_glance_client

  • Any existing scripts that rely on the database instance ACTIVE status should now rely on HEALTHY status.

Deprecation Notes

  • The following config options are deprecated in favour of a separate configuration section service_credentials introduced to define the Trove service user credentials for communication with other OpenStack services.

    [DEFAULT]
trove_auth_url
os_region_name
nova_proxy_admin_user
nova_proxy_admin_pass
nova_proxy_admin_tenant_id
nova_proxy_admin_tenant_name
nova_proxy_admin_user_domain_name
nova_proxy_admin_project_domain_name

Bug Fixes

  • Fixed the issue that the datastore version cannot be deleted because of dependency of deleted instances. When an instance or backup is deleted, the datastore version attribute is set to NULL in the database. When the datastore configuration parameter is deleted, the record is deleted from the database rather than only set the ‘deleted’ field to 1.
