I looked at using CEPH and even trialed it for a while. It did “fine,” but there were a few reasons we chose not to use it.
Never tried GlusterFS, however, GlusterFS is not really being actively developed. It’s maintained but not really being actively developed. There is a difference.

Each option has its own features and drawbacks. As far as I know Ceph requires at least 3 identical storage nodes which may be somehow more expensive than other options. Choosing a clustered filesystem depends on several factors suchas whether you need replication or not and what level of HA do you want. I myself am curious about which option do most experts here choose. Regards.
