Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1726301 Title: Nova should list instances even if it can't connect to a cell DB Status in OpenStack Compute (nova): In Progress Status in OpenStack Compute (nova) pike series: Confirmed Status in OpenStack Compute (nova) queens series: Confirmed Bug description: Description =========== One of the goals of cells is to allow nova scale and to have cells as failure domains. However, if a cell DB goes down nova doesn't list any instance. Even if the project doesn't have any instance in the affected cell. This affects all users. The behavior that I would expect is nova to show what's available from the nova_api DB if a cell DB is not available. (UUIDs and can we look into the request_spec?) Steps to reproduce ================== Have at least 2 child cells. Stop the DB in one of them. "nova list" fails with "ERROR (ClientException): Unexpected API Error." Not given any more information to the user. Expected result =============== List the project instances. For the instances in the affect cell, list the available information in the nova_api. Actual result ============= $nova list fails without showing the project instances. Environment =========== nova master (commit: 8d21d711000fff80eb367692b157d09b6532923f) To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1726301/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
