Abstract
Embodiments of the present disclosure relate to data management in a multitier storage system (MSS), the MSS comprises a storage virtualization controller (SVC) having at least one storage pool, and the storage pool comprises at least one logic volume, and the at least one logic volume comprises at least one tier. In response to the completion of a data migration from a source physical space of a first tier to a destination physical space of a second tier in a logic volume of a first storage pool, it is determined there is a free physical space in the source physical space. In response to the result of the determination indicating there exists a free physical space and the source physical space being thin provisioned, the free physical space of the source physical space is released to the storage array by the SVC.
