Abstract
Embodiments are directed to techniques for techniques for selecting a proper set of spare sections to use in a given failure scenario. These embodiments use a set of rules to define which spare sections are eligible to serve as spares for reconstruction of the RAID members on a disk that had failed. In addition, the set of rules may include weighted rules to allow optimization in the spare selection process.
