Description of problem (please be detailed as possible and provide log snippests): Red Hat provided script "ceph-external-cluster-details-exporter.py" does not support "--rados-namespace" parameter in downstream, only upstream. We have customer requesting this in downstream. The customer can use separate pools instead today, but would like to use namespace separation later on, mostly due to performance. The idea is to have a few pools with a high PG num to increase performance and spreading of data, one of the pools being used for RBD. Then they can logically separate that pool into several namespaces and limit access to them with ceph auth (pool + namespace). Then they dont have to make a new pool everytime someone wants RBDs, which potentially could be a lot, they'd just create a new namespace. Version of all relevant components (if applicable): OpenShift version 4.10 Ceph 16.2.8-85 Does this issue impact your ability to continue to work with the product (please explain in detail what is the user impact)? They can use separate pools today Is there any workaround available to the best of your knowledge? They can use separate pools today
