Efficient reconstruction technology can improve the service performance and reduce reconstruction time effectively.A mechanism ofdata volume reconstructed firstand a method ofredirection of read for reconstructed dataare proposed to improve the service performance during data recovery.Based on the mechanism and method,two strategies that take advantage of characteristics of user load,such ashot and cached datato direct reconstruction process andaffixation of user requeststo speed up reconstruction process,are given to improve performance and efficiency during data recovery.
