Hi Sean,

Thanks for raising this.

Can I clarify one related point, whether grenade is intended
primarily to catch intrinsic or extrinsic upgrade issues?

Or both?

Intrinsic in this context would for example be service A failing
post-upgrade due to a bad DB schema migration.

Whereas extrinsic would for example be service A failing post-
upgrade because some dependency/assumption with respect to
service B is now broken.

I ask because ceilometer when used with a "schema free" storage
driver may be more likely to suffer from extrinsic issues on
upgrade as opposed to intrinsic (e.g. nova changes a notification
payload between versions, as opposed to a failed db-sync as that
wouldn't even arise).

But surely such integration issues should have been caught in
advance via the normal Tempest testing of master-versus-master,
and wouldn't necessarily require the big-bang stable-to-master
approach of grenade to smoke out?

Or am I missing something obvious here?

Thanks,
Eoghan
