Abstract: Systems, methods, and computer readable storage mediums for discovering volumes which are good candidates for space reclamation. A storage subsystem identifies the file system storage capacity for a given volume from the file system metadata of the given volume. Then, the storage subsystem compares the file system capacity of the given volume to the allocated capacity on the storage subsystem. If the allocated capacity is greater than the file system capacity by a given threshold, the storage subsystem marks the given volume as a candidate for space reclamation and generates an alert to the user to reclaim the space of the given volume.

Abstract: Policy based path management, including: identifying a plurality of data communications paths between a storage system and an entity that issues input/output (‘I/O’) operations to the storage system; selecting, in dependence upon a path selection policy, a subset of data communications paths from the plurality of data communications paths between the entity and the storage system; and issuing, from the entity to the storage system, I/O operations using only the subset of data communications paths.

Abstract: Maintaining identifier service consistency within a storage system, including, responsive to a write operation for a dataset: assigning an identifier for the write operation, wherein the identifier is equal to a current identifier from an allowable set of identifiers; storing, within a metadata header for the dataset, metadata indicating the assigned identifier; and incrementing the current identifier; and responsive to determining that the incremented current identifier has caused a reservation event: updating a range corresponding to the allowable set of identifiers.
