Abstract
Exemplary methods, apparatuses, and systems include a controller node receiving a request to perform a consistency check of a distributed file system. The controller node transmits, to each of a plurality of nodes, a request for the node to use logical metadata of the distributed file system owned by the node to construct an expected copy of physical metadata mapped to the logical metadata, determine which of the plurality of nodes own actual portions of the physical metadata, transmit corresponding portions of the expected copy of the physical metadata to each of the nodes determined to own actual portions of the physical metadata, and compare expected copies of the physical metadata received from other nodes to the actual physical metadata owned by the node. The controller node receives a result of the comparison from each of the nodes, aggregates the received results, and generates an error report.
