Summary


In this chapter, we covered operations and maintenance tasks that need to be performed on a Ceph cluster. This chapter gives us an understanding of Ceph service management, scaling out, and scaling down a running Ceph cluster. The latter part of this chapter deals with failed disk drive replacement procedure for your Ceph cluster, which is something quite common for a medium to large cluster. Finally, you learned about powerful CRUSH maps and how to customize a CRUSH map. CRUSH map modification and tuning is quite an interesting and important part of Ceph; with it comes an enterprise-grade production storage solution. You can always get more information related to Ceph CRUSH maps at http://ceph.com/docs/master/rados/operations/crush-map/.

In the next chapter, we will learn about Ceph monitoring as well as logging and debugging your Ceph cluster with some troubleshooting tips.
