Releasing space on secondary storage device for resynchronization
Methods and systems for releasing space on a secondary storage device for resynchronization are provided. A system for releasing space on a secondary storage device for resynchronization includes a suspension detection module that determines that the relationship between a primary computing device and a secondary computing device is suspended. The system also includes a relationship resumption module that determines that the relationship between the primary computing device and a secondary computing device is resumed. The system further includes an extent release module that directs the secondary computing device to release extents in a secondary storage device of the secondary computing device that correspond to free extents in a primary storage device of the primary computing device. Additionally, the system includes a synchronization module that synchronizes data stored on the secondary storage device and the primary storage device.
