Comment 2 for bug 1663456

Hello,

I checked the issue but I'm not sure if this is a bug.
Indeed, when you use the CLI `openstack aggregate set --zone tztz --property foo=bar agg-sh` the updated_at field remains at 'None'.
The thing is that with this CLI, the metadata of the aggregate get updated and not the aggregate itself. Specifically the table nova_api.aggregate_metadata is getting updated.
On the other hand, if for example, you change the name of the aggregate, using the CLI `aggregate set --name agg-sh-new agg-sh`, the updated_at field gets a correct value since the table nova_api.aggregates is updated.

Best Regards,
Thodoris
