Is there a separate document for Train->Ussuri? Maybe the "Ussuri & later (CentOS 8)" text could be a link. -----Original Message----- From: Mark Goddard <mark@stackhpc.com> Sent: Wednesday, March 17, 2021 4:52 AM To: Braden, Albert <C-Albert.Braden@charter.com> Cc: openstack-discuss@lists.openstack.org Subject: [EXTERNAL] Re: [kolla] Upgrading from Centos7 Train to Centos8 Ussuri CAUTION: The e-mail below is from an external source.

I’m testing the Train7->Ussuri8 upgrade on a heat stack, following this document:
Hi Albert, The procedure takes you from Train on CentOS 7 to Train on CentOS 8. A Ussuri upgrade would be a separate step. I'll try to make that clearer in the docs. Mark
OpenStack Docs: CentOS 8
I used the instructions here to successfully remove a controller from the cluster:
https://docs.openstack.org/kolla-ansible/train/user/adding-and-removing-host...
Now I’m ready to add one, using the instructions here:
https://docs.openstack.org/kolla-ansible/train/user/adding-and-removing-host...
They say to run bootstrap-servers:
kolla-ansible -i <inventory> bootstrap-servers [ --limit <limit> ]
The question is, how to run it? My build server is running Centos 7 and has Python 2.7.5. Should I just download Ussuri to my existing build server, or do I need to build a new Centos 8 build server with Python 3?
I read the “potential issues” text but it’s not obvious whether it is safe to run Ussuri bootstrap-servers on Train hosts. If I don’t run bootstrap-servers on the Train controllers, then how does the new Ussuri controller get integrated (RMQ, MariaDB, etc.)?
I apologize for the nonsense below. I have not been able to stop it from being attached to my external emails.
