-----------------------------------
Resolution: Fixed
> setquota should have a check on usedNamespace [NameSpacequota]
> --------------------------------------------------------------

> Key: HDDS-8367
> URL: https://issues.apache.org/jira/browse/HDDS-8367
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Arun Sarin
> Assignee: Sumit Agrawal
> Priority: Minor
> Labels: pull-request-available
>
> This is a negative scenario that was tested
> While modifying setquota NameSpacequota we should have a check on
> usedNamespace already consumed by the volume.
> For Example these are the two possible scenarios:
> # In a case when namespace quota is not defined on the volume and there are
> some n numbers of buckets already created in that volume. Then if we are
> trying to setquota on that volume, there should be a check that it should not
> allow us to set a namespacequota less than usedNamespace
> # Second similiar scenario is Create volume with namespace quota --> create
> buckets --> Clear namespace quota --> Assign namespace quota less than
> already created buckets
> PFB the steps to recreate Scenario 1 :
> Step 1 - Create volume without namespace quota
