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.

Setting up the VSM environment


In order to use VSM, you are required to build the Ceph cluster using VSM. VSM cannot control or manage the existing Ceph cluster. In this recipe, we will use Vagrant to launch four virtual machines named vsm-controller, vsm-node1, vsm-node2, and vsm-node3. The vsm-controller virtual machine will act as the VSM controller node and vsm-nodes {1,2,3} will act as VSM agent nodes running the Ceph cluster.

How to do it…

  1. The Vagrantfile for launching the VSM virtual machines is available on the ceph-cookbook GitHub repository. Clone this repository, if you have not already done so:

    $ git clone https://github.com/ksingh7/ceph-cookbook.git
    
  2. Vagrantfile for launching the VSM nodes is located on the vsm directory:

    $ cd vsm
    
  3. Launch the virtual machines:

    $ vagrant up vsm-controller vsm-node1 vsm-node2 vsm-node3
    
  4. Once the virtual machines are launched, you should have four virtual machines running with proper networking in place.

  5. To log in to these VMs, use cephuser as both the...
