Abstract
Implementations claimed and described herein provide systems and methods for the efficient rebuilding of a failed storage device through sequential resilvering. In one implementation, blocks for resilvering are discovered. The blocks correspond to input/output requests not successfully completed for a failed storage device. A coarse grained sorting of the blocks is performed based on a block location of each of the blocks on the failed storage device. The block locations of the blocks are stored in memory according to the coarse grained sorting. A fine grained sorting of the blocks is performed based on the coarse grained sorting of the blocks. The blocks are sequentially resilvered based on the fine grained sorting.
