This update fixes the following bug among others:

• Previously, when the installation program checked to ensure the minimum 25GB disk space was available per node, the validation only checked the OpenStack flavor and not whether the separate root disk had been attached from dedicated storage. This caused clusters using a small flavor in combination with sufficient root disk space to be refused during installation. This has been fixed by considering the additional root disk space when validating the required disk space. Now you can successfully install a cluster with a combination of flavor disk space and root disk space. (BZ#1899161)
