Indeed, the question is on server-side encryption with keys managed by ceph on a per-user basis

As far as I'm aware, client-side encryption doesn't require any specific server support - it's a function of the client SDK used which provides the convenience of encrypting your data before upload and decryptiing it after download - https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingClientSideEncryption.html But you can always encrypt your data and then upload it via RGW, there is nothing anywhere that prevents that since uploaded objects are just a sequence of bytes, meta data won't be encrypted then You can also do server-side encryption by bringing your own keys - https://docs.ceph.com/en/quincy/radosgw/encryption/#customer-provided-keys I suspect you're asking for server-side encryption with keys managed by ceph on a per-user basis?

It seems that client-side encryption (or per use) is still on the way and not ready yet for today. Are there practical methods to implement encryption for CephFS with today' technique? e.g using LUKS or other tools?

For a couple of years already, work is being done to have fscrypt support for CephFS [1]. When that work ends up in mainline kernel (and distro kernels at some point) this will be possible. Gr.
