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 escalate into bigger problems. Furthermore, you also 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 now in a much better place to handle Ceph-related issues whenever they appear.
