It exits second superblock at the end of NILFS volume. But it can be not in fully synchronous state with primary ones (as I guess). Theoretically, it is possible to copy secondary superblock on the place of primary. But I am afraid that the NILFS volume can be in inconsistent state anyway. Do you sure that this volume doesn't contain another damaged sectors?
