Why not use CephFS instead? It has been thoroughly tested in real-world scenarios and has demonstrated reliability even at petabyte scale. As an open-source solution, it can run on the fastest NVMe storage, achieving very high IOPS with 10 Gigabit or faster interconnect.

I think their "Other distributed filesystem" section does not answer this question.

We have a couple ceph clusters.

If my systems guys are telling me the truth is it a real time sink to run and can require an awful lot of babysitting at times.

IMO this is the problem with all storage clusters that you run yourself, not just Ceph. Ultimately, keeping data alive through instance failures is just a lot of maintenance that needs to happen (even with automation).
