Chapter 1. Introduction
Using the Red Hat Ceph file system (CephFS) through the native CephFS protocol is available only as a Technology Preview, and therefore is not fully supported by Red Hat. The deployment scenario described in this document should only be used for testing and should not be deployed in a production environment.
For more information about Technology Preview features, see Scope of Coverage Details.
Red Hat supports using CephFS through NFS. For more information, see Deploying the Shared File Systems service with CephFS through NFS.
With the OpenStack Shared File Systems service (manila) you can provision shared file systems that can be consumed by multiple compute instances.
This release includes a technology preview of the necessary driver for Red Hat CephFS (namely,
manila.share.drivers.cephfs.cephfs_native.CephFSNativeDriver). This driver allows the Shared File System service to use CephFS as a back end.
The recommended method for configuring a Shared File System back end is through the director. Doing so involves writing a custom environment file.
With this release, the director can now deploy the Shared File System with a CephFS back end on the overcloud. This document explains how to do so.
