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.

I admin'd a cluster about 10 years back and it was 'ok' then, around bluestore. One issue was definitely my mistake but it wasn't all that bad.
