Hi all, jumping on this thread as we have requests for which per-client fs mount encryption makes a lot of sense:
> What kind of security to you want to achieve with encryption keys stored > on the server side? One of the use cases is if a user requests a share with encryption at rest. Since encryption has an unavoidable performance impact, it is impractical to make 100% of users pay for the requirements that only 1% of users really have. Instead of all-OSD back-end encryption hitting everyone for little reason, encrypting only some user-buckets/fs-shares on the front-end application level will ensure that the data is encrypted at rest. It may very well not serve any other purpose, but these are requests we get. If I could provide an encryption key to a ceph-fs kernel at mount time, this requirement could be solved very elegantly on a per-user (request) basis and only making users who want it pay with performance penalties.
