Abstract
A method for efficiently handling partial write requests in a storage system includes allocating a new block of data for the new partial data, and allocating a record in an extent map to record the location of the new partial data block, the location of the old partial data block and the offset length for each data block. Data blocks can be repackaged in the background when system resources are available. A full, but misaligned write request is also efficiently handled by writing the new data to a newly allocated data block and allocating new records in an extent map to record information corresponding to two partial write operations.
