Re: [rdo-list] Upgrading from Newton to Ocata

Hello RDO Team, I'm still fairly new to OpenStack so this may be because I didn't read the documentation closely enough before the upgrade, but I ran into an issue that I was hoping to get some clarification on. I used this page to perform the upgrade [1]. Everything went smoothly until setting up cells for the first time. I had not done this in Newton. I got to step 14: "List registered cells to get their UUIDs:" which worked great. I had cell0 and cell1 created from previous steps, everything seemed to be in place. The next step says: "Pass the UUIDs to the map_instances command to map instances to cells:" with the following command example: "# su -s /bin/sh -c "nova-manage cell_v2 map_instances --cell_uuid <cell UUID>" nova" I took this to mean run that command for both cell0 and cell1. So I did. That mapped all my instances to cell0. I then started seeing errors like this in the logs: ERROR nova.api.openstack.extensions DriverLoadFailure: Failed to load transport driver "none": No 'oslo.messaging.drivers' driver found, looking for u'none' After much searching, I found the transport_url for cell0 in the database was set to "none:///" which is what was causing the error. I was able to create new instances, but not run any commands at all on current instances and all new instances were brought up in cell1. So I moved all current instances to cell1 by manually updating the database and all the errors went away and everything is running correctly. So my question is, did I do something else wrong that would cause this not to work properly or should those instructions be clarified a bit to say map instances to cell1, not cell0?

In my searching I did find other guides that did all these same things, but specifically said map instances to cell1.
