Method and device for executing batch failback on block object

The embodiment of the invention discloses a method and device for executing batch failback on a block object. The method comprises the following steps: executing batch failback on partial block objects of one or multiple file systems in an existing file system; based on quantity of recorded executed failback, determining delay time required for executing the next failback; and after the delay time passes, executing the next failback on the residual block objects. Compared with the prior art, the embodiment of the invention has the advantages that the quantity of the block objects treated in one failback process can be controlled, and the delay time between two failback processes is dynamically adjusted, so that great pressure can not be applied to a storage processor in a starting state in the short term; and failback on all the block objects of the same file system can be completed in one failback process, so that basic consistency is guaranteed.
