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 Calamari master server


In the last recipe, we compiled the packages required for Calamari, which includes the calamari-server, calamari-client, and diamond. If you have not compiled these packages by yourself, you can download them from my GitHub repository at https://github.com/ksingh7/ceph-calamari-packages/tree/master/CentOS-el7.

How to do it…

In this demonstration, we will be configuring ceph-node1 as the Calamari master server, as well as the salt-minion node, ceph-node2, and ceph-node3 as salt-minion nodes only. At the time of writing this recipe, Calamari did not support salt version 2015, so I have intentionally used salt version 2014.

Let's now begin the installation of the Calamari server:

  1. On ceph-node1, install the dependency packages required by salt and the Calamari server:

    # yum install -y python-crypto PyYAML systemd-python yum-utils m2crypto pciutils python-msgpack systemd-python python-zmq
    
  2. By default, CentOS7 will install salt's latest version, so in order to install...
