Exporting kernel client mounts with the kernel NFS server is tested as part of the regular testing we do on CephFS, so you should find it pretty stable. This is definitely a legitimate way of putting a layer of security between your application servers and your storage cluster. NFS Ganesha is also an option, that is not as well tested (yet) but it has the advantage that you can get nice up to date Ceph client code without worrying about upgrading the kernel. I'm not sure if there are recent ganesha packages with the ceph FSAL enabled available online, so you may need to compile your own. When you say you tried using the server as an NFS gateway, was that with kernel NFS + kernel CephFS? What kind of activities did you find were running slowly (big files, small files, etc...)?
