Abstract: In order to construct the effective and high reliable fault detection mechanism in distributed storage system, a piggyback adaptive fault detection algorithm based on mixed status is presented, named MSP-AFD. A new fault detection framework for the distributed storage system is presented. It computes the detection delay based on the method of load prediction, and tunes the timeout parameters adaptively. Experimental results show that the fault detection performance of MSP-AFD is good.

Key words: fault detection, distributed storage system, load prediction, piggyback mode
