https://bugs.launchpad.net/nova/+bug/1656276 - Error running nova-manage cell_v2 simple_cell_setup when configuring nova with puppet-nova
https://bugs.launchpad.net/nova/+bug/1649341 - Undercloud upgrade fails with "Cell mappings are not created, but required for Ocata"
- Fixed on master in Nova, backport proposed to stable/newton. However, this change caused issues for TripleO on master which is bug 1656276 above.
https://bugs.launchpad.net/nova/+bug/1656017 - nova-manage cell_v2 map_cell0 always returns a non-0 exit code

The deployment/upgrade process needs to be documented in more than just the release notes.
- dansmith was going to work on a blog post to start this.
- On a side note, we should also have man pages for the cell_v2 commands because there is confusion around the inputs and outputs and how return codes should be treated, i.e. is 1 an error or not?
- alaski's older docs patch (which is probably out of date now but might be useful) is here: https://review.openstack.org/#/c/267153/
Integrate the 'nova-status upgrade check' CLI into the CI/QA system (grenade).
Older tracking etherpads (these may be out of date):

- https://etherpad.openstack.org/p/nova-multiple-cells

Should the computes self-register with a cell when the compute_nodes record is created from the ResourceTracker? https://review.openstack.org/#/c/369634/
Why can't we create an empty cell, i.e. a cell mapping with no computes? This is a fresh-install scenario.
