Public bug reported: When we destroy a flavor from the api database we send a notification:
https://github.com/openstack/nova/blob/5a363a0d72e7dd8d79d7e950effc1d8a5fdc801b/nova/objects/flavor.py#L608 However if flavor.projects isn't loaded we try to lazy-load it: https://github.com/openstack/nova/blob/5a363a0d72e7dd8d79d7e950effc1d8a5fdc801b/nova/objects/flavor.py#L617 Which is going to result in a FlavorNotFound error because we just deleted the flavor from the API database: https://github.com/openstack/nova/blob/5a363a0d72e7dd8d79d7e950effc1d8a5fdc801b/nova/objects/flavor.py#L65 This doesn't blow everything up because we fallback to the main cell database to get the flavor projects: https://github.com/openstack/nova/blob/5a363a0d72e7dd8d79d7e950effc1d8a5fdc801b/nova/db/sqlalchemy/api.py#L5194 Which just returns an empty list. I noticed this when removing the main db fallback paths in this change and had to workaround it: https://review.openstack.org/#/c/460377/ But it's really a separate bug fix. ** Affects: nova Importance: Medium Assignee: Matt Riedemann (mriedem) Status: Triaged ** Tags: notifications ** Changed in: nova Status: New => Triaged ** Changed in: nova Importance: Undecided => Medium ** Changed in: nova Assignee: (unassigned) => Matt Riedemann (mriedem) ** Tags added: notifications -- You received this bug notification because you are a member of Yahoo!
