Zusammenfassung:Systems, methods, and machine-readable media are disclosed for isolating and reporting a volume placement error for a request to place a volume on a storage platform. A volume placement service requests information from a database using an optimized database query to determine an optimal location to place a new volume. The database returns no results. The volume placement service deconstructs the optimized database query to extract a plurality of queries. The volume placement service iterates over the plurality queries, combining queries in each iteration, to determine a cause for the database to return no results. The volume placement service determines based on the results of each iterative database request a cause the database to return an empty result. The volume placement service provides an indication of the cause for returning an empty result.
