摘要
A logical group of data blocks stored in a first node is migrated to a second node according to a method that includes determining a first metric for each logical group of data blocks stored in the first node, the first metric representing a total size of the data blocks in the logical group, determining a second metric for each logical group of data blocks stored in the first node, the second metric representing a total size of the data blocks in the logical group that are uniquely stored in the first node, and selecting a logical group of data blocks for migration from the first node to the second node based on the first metric and the second metric.
