摘要：Storage space is reclaimed by cleaning and compacting data objects where dataobjects are stored by immutable storage. A storage area of which space needs to bereclaimed is identified. Active and stale data objects stored in a storage area are
identified, and only active data objects are transferred to a shadow storage area from thestorage area when recovering storage space. I/O operations can be fulfilled from thestorage area and the shadow storage area. Compaction requests and I/O requests arethrottled according to QOS parameters. Recovery of storage space does not cause afailure to meet performance requirements for any storage volume.
