Troubleshooting

Ceph is largely autonomous in taking care of itself and recovering from failure scenarios, but in some cases human intervention is required. This chapter will look at common errors and failure scenarios and how to bring Ceph back to working order by troubleshooting them.

In this chapter we will cover the following topics:

How to correctly repair inconsistent objects
How to solve problems with the help of peering
How to deal with near_full and too_full OSDs
How to investigate errors via Ceph logging
How to investigate poor performance
How to investigate PGs in a down state

Fisk

Nick Fisk is an IT specialist with a strong history in enterprise storage. Having worked in a variety of roles throughout his career, he has encountered a wide variety of technologies. In 2012, Nick was given the opportunity to focus more on open source technologies, and this is where he got his first exposure to Ceph. Having seen the potential of Ceph as a storage platform and the benefits of moving away from the traditional closed stack storage platforms, Nick pursued Ceph with keen interest. Throughout the following years, his experience with Ceph increased with the deployment of several clusters and enabled him to spend time in the Ceph community, helping others and improving certain areas of Ceph.
