Abstract
Techniques for selecting a storage node of a storage system to store data include applying a first function to at least some data chunks of an extent to provide respective first values for each of the at least some data chunks. A storage node, included within multiple storage nodes of a storage system, is selected to store the extent based on a majority vote derived from the respective first values.
