Abstract
A computer program product, system, and computer implemented method for an approach to manage objects that tightly couple snapshots and clone management together. Specifically, the present disclosure provides for an approach where metadata for snapshots and clones of the extent can be managed using a single set of metadata that intermingles entries for any number of snapshots and clones together. This provides for a single place in which the storage system can access extent information for a given extent to determine what information corresponds to a request (e.g., create, read, update, delete requests). Additionally, the approaches provided herein further include support for variable sized allocation units and tombstones (that represent sparse data using metadata). In some embodiments, metadata and data referenced by corresponding metadata are stored on the same storage devices.
