Abstract
Storage systems and methods are presented. In one embodiment, a storage reclamation method comprises performing a potential reclamation identification process, wherein the potential reclamation identification process includes determining if there is the potential for reclaiming storage resources; performing a reclamation process, wherein reclamation is performed on storage resources identified by the potential reclamation identification process as being eligible for reclamation, and wherein the storage resources correspond to free space associated with a data file; and performing a valid free space indication process, wherein a valid free space indication process includes forwarding a valid free space indication recognizable to an application as a valid free space indication when the application attempts to direct a read to the storage spaces reclaimed by the reclamation process.
