Preface

Red Hat OpenStack Platform (Red Hat OpenStack Platform) provides the foundation to build a private or public Infrastructure-as-a-Service (IaaS) cloud on top of Red Hat Enterprise Linux. It offers a massively scalable, fault-tolerant platform for the development of cloud-enabled workloads.

This guide discusses procedures for creating and managing persistent storage. Within OpenStack, this storage is provided by three main services:

  • Block Storage (openstack-cinder)
  • Object Storage (openstack-swift)
  • Shared File System Storage (openstack-manila)

These services provide different types of persistent storage, each with its own set of advantages in different use cases. This guide discusses the suitability of each for general enterprise storage requirements.

You can manage cloud storage using either the OpenStack dashboard or the command-line clients. Most procedures can be carried out using either method; some of the more advanced procedures can only be executed on the command line. This guide provides procedures for the dashboard where possible.

This guide documents the use of crudini to apply some custom service settings. As such, you need to install the crudini package first:
