Abstract
Techniques for reclaiming storage space are disclosed herein. According to one embodiment, a storage space reclamation method includes a storage host creating at least one temporary logical container of data in a storage volume managed by a file system of a host so that a predetermined portion of storage capacity of the storage volume is occupied. Access to the storage volume is provided by a network storage controller to the storage host. The storage host translates a host address range for the file system of each temporary logical container of data into a storage controller address range for the network storage controller. The storage host requests the network storage controller to deallocate blocks the locations of which are indicated by the storage controller address range, and then deletes the at least one temporary logical container of data.
