Chapter 8. Upgrading the overcloud
Upgrade Red Hat OpenStack Platform content across the whole overcloud on each stack in your environment.
8.1. Upgrading RHOSP on all nodes in each stack
Upgrade all overcloud nodes to Red Hat OpenStack Platform (RHOSP) 17.1 for each stack, starting with the main stack.
You must ensure that the pacemaker is running on all controllers before you upgrade the overcloud nodes.
For information about the duration and impact of this upgrade procedure, see Upgrade duration and impact.
Procedure
-
Log in to the undercloud host as the
stackuser. Source the
stackrcundercloud credentials file:$ source ~/stackrc
Upgrade RHOSP on all nodes in your main stack:
$ openstack overcloud upgrade run --yes --stack <stack> --debug --limit allovercloud,undercloud --playbook all
Replace <stack> with the name of the overcloud stack that you want to upgrade the nodes on.
Repeat this step for each stack in your RHOSP deployment.
If you have a multi-cell environment, you must upgrade RHOSP on the cell stacks before you upgrade RHOSP on the overcloud stack.
