Abstract
An improved technique for managing data storage includes relocating allocated blocks within a range of a physical address space of a file system to free the allocated blocks. The range has a length equal to a length of one or more full stripes of a RAID group that stores content of the file system. In response to receiving data to be written to the file system, the file system arranges the data in the range of contiguous blocks and performs one or more full-stripe writes to write the data to the RAID group.
