About Thin Reclamation

Some vendors support a reclamation capability on Thin Storage arrays, on which the administrator can initiate the process of reclaiming free storage from the file systems or disks in the LUN or array so that this storage is released to the free storage pool. Such arrays and LUNs are referred to as Thin Provisioning arrays and LUNs. The Storage Foundation Thin Reclamation feature reclaims free blocks through command line and programmatic interfaces.
