EFFICIENT REPLICA CLEANUP DURING RESYNCHRONIZATION

摘要

Mechanisms are provided for efficient replica cleanup during resynchronization. According to various embodiments, a plurality of deleted data segment ranges on a first storage node may be identified. The first storage node may be configured to store a plurality of data segments. Each of the plurality of data segments may have associated therewith a respective identifier. Each of the data segment ranges may designate one or more data segments that have been deleted from the first storage node. The plurality of deleted data segment ranges may be transmitted to a second storage node configured to mirror the plurality of data segments stored on the first storage node. The plurality of deleted data segment ranges may be capable of being used to identify one or more data segments to delete from the second storage node.
