/**
 * Miscellaneous disk-related IOException occurred when handling a request.
 * Client should request metadata update and retry if the response shows KafkaStorageException
 *
 * Here are the guidelines on how to handle KafkaStorageException and IOException:
 *
 * 1) If the server has not finished loading logs, IOException does not need to be converted to KafkaStorageException
 * 2) After the server has finished loading logs, IOException should be caught and trigger LogDirFailureChannel.maybeAddOfflineLogDir()
 *    Then the IOException should either be swallowed and logged, or be converted and re-thrown as KafkaStorageException
 * 3) It is preferred for IOException to be caught in Log rather than in ReplicaManager or LogSegment.
