How To Configure Single-Node Ceph Cluster To Run Properly
Ceph is designed to be a fault-tolerant, scalable storage system. This means that in a production environment, it is expected that at a minimum, there will be three Ceph nodes in a cluster. If you can only afford a single node for now, or if you need only a single Ceph node for testing purposes, You will run into some problems. A single-node Ceph cluster will consider itself to be in a degraded state, since by default, it will be looking for another node to replicate data to. You will not be able to use it. This How-To will show you how to reconfigure a single Ceph Node so that it will be usable. This will work if your Ceph Node has at least two OSDs available. We have added an introduction to ceph in our previous article to get started.
