Abstract: Embodiments are directed to creating global, aggregated namespaces for storage management and to providing consistent namespaces in a distributed storage system. In one scenario, a computer system defines data storage objects for each data storage node. The data storage objects uniquely identify storage elements of the data storage nodes, where each data storage object includes various associated attributes. The computer system replicates the defined data storage objects and any associated attributes from a first data storage node to a second, different data storage node among the data storage nodes. As such, the defined data storage objects are visible from any node in the data storage nodes. The computer system also aggregates the defined data storage objects for each of the data storage nodes and creates a global, aggregated namespace that includes the aggregated data storage objects for each of the data storage nodes.
