Ceph is a unified distributed storage system designed for reliability and scalability. This technology has been transforming the software-defined storage industry and is evolving rapidly as a leader with its wide range of support for popular cloud platforms such as OpenStack, and CloudStack, and also for virtualized platforms. Ceph is backed by Red Hat and has been developed by community of developers which has gained immense traction in recent years. This book will guide you right from the basics of Ceph , such as creating blocks, object storage, and filesystem access, to advanced concepts such as cloud integration solutions. The book will also cover practical and easy to implement recipes on CephFS, RGW, and RBD with respect to the major stable release of Ceph Jewel. Towards the end of the book, recipes based on troubleshooting and best practices will help you get to grips with managing Ceph storage in a production environment. By the end of this book, you will have practical, hands-on experience of using Ceph efficiently for your storage requirements.

Creating a Ceph cluster using VSM

In the last recipe, we just installed VSM; we do not yet have a Ceph cluster. In this recipe, we will create the Ceph cluster using VSM so that VSM can manage this cluster later. You will find that deploying the Ceph cluster is extremely easy with VSM.

How to do it...

To create the Ceph cluster from the VSM dashboard, navigate to Cluster Management | Create Cluster, and then click on the Create Cluster button.

VSM Dashboard create cluster section

If you check preceding screenshot, version 2.2.0 has the Import Cluster tab. As 2.20 is still in beta, we need to use a couple of hacks:

  1. Disable MDSs and RGWs and restart vsm-api.
