Chapter 6. Pre-deployment validations for Ceph Storage

To help avoid overcloud deployment failures, validate that the required packages exist on your servers.

6.1. Verifying the ceph-ansible package version

The undercloud contains Ansible-based validations that you can run to identify potential problems before you deploy the overcloud. These validations can help you avoid overcloud deployment failures by identifying common problems before they happen.

Procedure

Verify that the correction version of the ceph-ansible package is installed:

$ ansible-playbook -i /usr/bin/tripleo-ansible-inventory /usr/share/openstack-tripleo-validations/validations/ceph-ansible-installed.yaml

6.2. Verifying packages for pre-provisioned nodes

When you use pre-provisioned nodes in your overcloud deployment, you can verify that the servers have the packages required to be overcloud nodes that host Ceph services.

For more information about pre-provisioned nodes, see Configuring a Basic Overcloud using Pre-Provisioned Nodes.

Procedure

Verify that the servers contained the required packages:

ansible-playbook -i /usr/bin/tripleo-ansible-inventory /usr/share/openstack-tripleo-validations/validations/ceph-dependencies-installed.yaml
