Ceph Cookbook

Overview of this book

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. This cutting-edge technology has been transforming the storage industry, and is evolving rapidly as a leader in software-defined storage space, extending full support to cloud platforms such as Openstack and Cloudstack, including virtualization platforms. It is the most popular storage backend for Openstack, public, and private clouds, so is the first choice for a storage solution. Ceph is backed by RedHat and is developed by a thriving open source community of individual developers as well as several companies across the globe. This book takes you from a basic knowledge of Ceph to an expert understanding of the most advanced features, walking you through building up a production-grade Ceph storage cluster and helping you develop all the skills you need to plan, deploy, and effectively manage your Ceph cluster. Beginning with the basics, you’ll create a Ceph cluster, followed by block, object, and file storage provisioning. Next, you’ll get a step-by-step tutorial on integrating it with OpenStack and building a Dropbox-like object storage solution. We’ll also take a look at federated architecture and CephFS, and you’ll dive into Calamari and VSM for monitoring the Ceph environment. You’ll develop expert knowledge on troubleshooting and benchmarking your Ceph storage cluster. Finally, you’ll get to grips with the best practices to operate Ceph in a production environment.

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…

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

  2. Select all the nodes by clicking on the checkbox next to the ID, and finally, click on the Create Cluster button:

  3. The Ceph cluster's creation will take a few minutes. VSM will display very briefly what it's doing in the background under the status field of the dashboard, as shown next:

    After cleaning, it will mount disks, as shown under the status field of the dashboard in the following screenshot:

  4. Once the Ceph cluster deployment is completed, VSM will display the node status as Active.

  5. Finally, check the cluster status from Dashboard | Cluster Status.
