This came up in the operators mailing list back in June [1] but given the subject probably didn't get much attention. Basically there is a really old bug [2] from Grizzly that is still a problem and affects multiple projects. A tenant can be deleted in Keystone even though other resources in other projects are under that project, and those resources aren't cleaned up. Keystone implemented event notifications back in Havana [3] but the other projects aren't listening on them to know when a project has been deleted and act accordingly. The bug has several people saying "we should talk about this at the summit" for several summits, but I can't find any discussion or summit sessions related back to the bug. Given this is an operations and cross-project issue, I'd like to bring it up again for the Vancouver summit if there is still interest (which I'm assuming there is from operators). There is a blueprint specifically for the tenant deletion case but it's targeted at only Horizon [4]. Is anyone still working on this? Is there sufficient interest in a cross-project session at the L summit? Thinking out loud, even if nova doesn't listen to events from keystone, we could at least have a periodic task that looks for instances where the tenant no longer exists in keystone and then take some action (log a warning, shutdown/archive/, reap, etc). There is also a spec for L to transfer instance ownership [5] which could maybe come into play, but I wouldn't depend on it.

I will apologize ahead of time for saying 'projects' for services like nova, glance, cinder, etc, while also talking about projects/tenants in keystone, I realize this is confusing. :)
