You can define quotas per directory but there are a number of caveats with quotas: http://docs.ceph.com/docs/master/cephfs/quota/ > And do I need to define the OSD Restriction? > I think you would still need to do this if you have other pools > "To prevent clients from writing or reading data to pools other than those > in use for CephFS, set an OSD authentication capability that restricts > access to the CephFS data pool(s)." > > THX > > > > 20.
