Ceph or LVM disk as ELK storage

[Christian_Dahlqvist]

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.

Why NFS is to be avoided for data directories

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…

CEPH Storage For Elasticsearch

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?
