Bug Description

With versioned notifications, the instance payload tries to attach a flavor payload which it looks up from the instance. It uses the one which is attached in instance_extras however there seems to be a scenario where the disabled field is missing in the database, causing all operations to fail in the notification stage.

The JSON string for the flavor in the database is attached below (note this is a cloud with a long lifetime so it might be some weird conversion at some point in the life time of the cloud).

The temporary workaround as suggested by Matt was to switch to unversioned notification which did the trick.

I had the same thing happen in my environment.
The environment was upgraded to Pike all they way back from Juno (one by one, over time).
The flavor was created ~2014 on whatever was stable then.

This is also visible in tssurya's environment. I'm wondering if we can implement a nova-manage heal-instance-flavor command for these environment as I'm not sure I will be able to find the root cause why the disable field is missing from these flavors.

Looking at juno-eol code, I came across what I think might result in "ValueError: Field `disabled' cannot be None".

In the long long ago, we stored the flavor information in the instance.system_metadata field:

https://github.com/openstack/nova/blob/juno-eol/nova/compute/flavors.py#L327

Note that system_metadata_flavor_props does not include the "disabled" key, so we wouldn't have stored an instance_type_disabled key in the instance system_metadata.

Eventually we migrated how the embedded flavor in instance system_metadata was stored:

https://review.openstack.org/#/c/135700/56/nova/objects/instance.py@368

But we still pulled it out of the instance system_metadata to do that. Since that wouldn't have instance_type_disabled, we wouldn't store a serialized Flavor object with the disabled field set.

Then when we load up these old instance.flavor values from the serialized Flavor primitive in the instance_extra table, there is no 'disabled' key in the dict and we try to set Flavor.disabled=None which blows up since it's not a nullable field.

    Default embedded instance.flavor.disabled attribute

    Before we stored flavors in instance_extra, certain fields, defined
    in nova.compute.flavors.system_metadata_flavor_props, were stored
    in the instance.system_metadata for the embedded instance.flavor.
    The "disabled" field wasn't one of those keys, however, so really
    old instances that had their embedded flavor converted to the
    serialized instance_extra form won't have the disabled attribute
    set and we need to default those here so callers, like the
    versioned notfication FlavorPayload, don't explode trying to load
    instance.flavor.disabled.

Same issue, very old instances wouldn't have the embedded flavor.is_public field stored because of this whitelist:

http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/flavors.py#n52

So we'll need to default is_public=True when reading the embedded instance.flavor and is_public is not set.

    Default embedded instance.flavor.disabled attribute

    Before we stored flavors in instance_extra, certain fields, defined
    in nova.compute.flavors.system_metadata_flavor_props, were stored
    in the instance.system_metadata for the embedded instance.flavor.
    The "disabled" field wasn't one of those keys, however, so really
    old instances that had their embedded flavor converted to the
    serialized instance_extra form won't have the disabled attribute
    set and we need to default those here so callers, like the
    versioned notfication FlavorPayload, don't explode trying to load
    instance.flavor.disabled.
