摘要: The invention provides a method of improving the disk array data reconstruction efficiency. is characterized in that process treating same stripe carried out two threads, as for one thread, reading operation only, other writing out, and amount blocks buffer queue limited larger than so to asynchronously write without influencing operation; an original read checked, obtained by checking added into queue; thread used acquires from queue. With adoption method, position per time needs be marked recorded can updated super block information, thus preventing starting anew after restart due power off.
