Feature #57333
Quota support at the rbd namespace level
0%
Description
RBD images can now be segregated within isolated namespaces within the same pool.
When combined with CephX capabilities, users can be restricted to specific pool namespaces to restrict access to RBD images.
However, a user can create an rbd image of any size within its namespace as there is no such quota or restrictions on a user basis or on a namespace basis to keep each user in check.

+1 for this feature. This feature was also discussed at Cephalocon 2023 dev summit, and everyone involved agreed this would be very useful. For Ceph CSI (Kubernetes) deployments only a single pool would be needed to serve multiple independent clusters. For block storage / VM setups a single pool would be all you need to serve multiple different cloud instances / iSCSI / NVMeOF setups.
