Ceph and other types of distributed storage are generally not recommended due to performance and correctness/stability concerns. As far as I know this has not changed since the following threads were created. If there has been any official change in stance I am sure somebody will come in and correct me.

> Yes, latency is a big factor. Another is correctness: Elasticsearch expects the filesystem under the data path to act like a local filesystem, and uses some fairly advanced features that are typically not well supported by nonlocal storage. For instance it needs locking and atomic file creation to work right; it's notoriously tricky to get NFS to do these things correctly. Distributed storage like Ceph and GlusterFS is something I'd avoid. These technologies are still maturing IMO and have been…

> We are planning to create an Elasticsearch cluster over Kubernetes, and for this CEPH distributed file system would be used as Storage, I understand that elastic recommends using local storage, however are there any known performance issues or other issues in general using CEPH. Has anyone from elastic tested Elasticsearch 7 on CEPH storage?
