Abstract
A distributed storage system includes a plurality of nodes comprising a first node, wherein a total number of nodes in the distributed storage system is represented by n, wherein a file stored in the distributed storage system is recovered from a subset of a number of nodes represented by k upon a file failure on a node in the distributed storage system, and wherein a failed node in the plurality of nodes is recovered from a number of helper nodes of the plurality of nodes represented by d. Upon detecting a failure in the first node, each helper node of the number of helper nodes is configured to determine a repair-encoder matrix, multiply a content matrix by the repair-encoder matrix to obtain a repair matrix, extract each linearly independent column of the repair matrix, and send the linearly independent columns of the repair matrix to the first node.
