In this chapter, you learned how to deal with problems that Ceph is not able to solve by itself. You now understand the necessary steps to troubleshoot a variety of issues that, if left unhandled, could become bigger problems. Furthermore, you have a good idea of the key areas to look at when your Ceph cluster is not performing as expected. You should feel confident that you are in a good place to handle Ceph-related issues whenever they appear.
In the next chapter, we will continue to look into troubleshooting processes and will explore the situations where data loss has already happened.
