摘要
The disclosure provides an approach for zeroing allocated storage blocks of a file. The blocks are zeroed in the background, during a normal operation of a storage system, thus lowering the chance that the latency of a storage operation would be increased by the zeroing process. The approach also precludes a delay in being able to use the file, the delay caused by pre-zeroing the storage blocks prior to use of the file.
