I think the multiple namespace feature would be more appropriate for your use case. So that would be multiple file systems within the same pools rather than multiple pools in a single filesystem.
With that said, that might be overkill for your requirement. You might be able to achieve what you need with path restriction: http://docs.ceph.com/docs/master/cephfs/client-auth/ On Thu, Jul 20, 2017 at 10:23 AM, <c.mo...@web.de> wrote: > 19.
