• This documents expects that your cloud is deployed with the latest newton tag(vN.1.0) of the ntnuopenstack repository.
• Your cloud is designed with one of the two architecturesarchitecture:
  • Each openstack project have their own VM(s) for their services
  • All openstack services is deployed on 3 physical controllers
• You have a recent mysql backup in case things go south.

1. Run puppet with the ocata modules/tags
2. Run apt-get dist-upgrade
   1. If it fails, verify that /etc/mysql/my.cnf.fallback exists. If it doesnt, create it with the content "!includedir /etc/mysql/conf.d/"
   2. Keystone often have to be reinstalled; so "apt-get purge keystone" followed by a puppet-run fixes a lot
3. Run puppet again
4. Perform the DB sync
   1. keystone-manage db_sync
5. Restart keystone services

Nova

Create nova cells database on a mysql host:

create database nova_cell0;
grant all privileges on nova_cell0.* TO 'nova'@'<mgmt-nett>' IDENTIFIED BY 'NOVA DB PASSORD';
grant all privileges on nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA DB PASSORD';

On the services-node:

# nova-manage cell_v2 simple_cell_setup --transport-url rabbit://rabbit:<KANINPASSORD>@<KANIN-IP>/

On the API node:

1. Run puppet with the ocata modules/tags
2. Run apt-get dist-upgrade
3. Run puppet again
4. Perform the DB sync
   1. nova-manage db sync
   2. nova-manage api_db sync
5. Restart nova services

Controller based architecture

On the controller-based architecture there is a lot less control of order etc. We are thus recommending the following approach:

1. Stop puppet on all controllers, and stop all openstack services
2. Select one controller to be the first one to go:
   
3. Run puppet with the ocata modules/tags
Perform a dist-upgradeSync databases
4. keystone-manage db_sync
5. cinder-manage db sync
glance-manage db syncneutron-db-manage upgrade head
6. nova-manage db sync
7. nova-manage api_db sync
8. Run puppet again
9. Restart all services.
10. Verify successful upgrade
Upgrade the next two controllers, without step c: sync databases.

Compute-nodes

When controllers etc. are upgraded, it is time to do the same on the comute-nodes. Compute nodes are simple to upgrade:
