Abstract
Processing data in a distributed data storage system generates a sparse check matrix correlating data elements to data syndromes. The system receives notification of a failed node in the distributed data storage system, accesses the sparse check matrix, and determines from the sparse check matrix a correlation between a data element and a syndrome. The system processes a logical operation on the data element and the syndrome and recovers the failed node.
