Public bug reported: While creating a new cell_v2 using command "nova-manage cell_v2 create_cell", if no parameter ie. "transport-url" and "database_connection" are given then the values of "transport-url" and "database_connection" of default cell are picked from nova.conf which are already mapped to the default cell and it result into error for duplicate combination of "transport_url" and "database_connection".
Command Output: [root@openstackq ~(keystone_admin)]# nova-manage cell_v2 create_cell /usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported exception.NotSupportedWarning The specified transport_url and/or database_connection combination already exists for another cell with uuid 75c8bcda-6a34-468f-ba85-b3c7b977fd4b. Both the arguments must be positional. Code changes required and both the parameters "transport-url" and "database_connection" are to be treated positional. As a workaround, user is providing both the arguments along with command. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
