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.

Adding Ceph nodes to Calamari


At this stage, we have a running Calamari master server. In order to monitor your Ceph cluster with Calamari, we need to add Ceph nodes to Calamari. Let's begin that.

Note

Since ceph-node1 plays the dual role of being a Calamari master server and Calamari Ceph node, we have already performed the first two steps on ceph-node1. Execute the steps on ceph-node2 and ceph-node3 until otherwise specified.

How to do it…

  1. On ceph-node2 and ceph-node3, enable the salt 2014 yum repositories:

    # wget https://copr.fedoraproject.org/coprs/saltstack/salt/repo/epel-7/saltstack-salt-epel-7.repo -O /etc/yum.repos.d/saltstack-salt-epel-7.repo
    
  2. Install the dependent packages manually:

    # yum install -y python-crypto PyYAML systemd-python yum-utils m2crypto pciutils python-msgpack systemd-python python-zmq
    

From now on, perform these steps on ceph-node1, ceph-node2, as well as ceph-node3:

  1. Install the salt-minion-2014 package:

    # yum --disablerepo="*" --enablerepo="salt*" install -y salt-minion...
