Description
It would be useful it we could enable the metadata_csum feature on the MDT/OST, so long as this is being properly handled by e2fsck. It would be a valuable addition to the "inode badness" metric that we currently have added to e2fsck. It isn't quite as useful by itself as the block checksums used by ZFS, since ZFS also has backup copies of all metadata blocks, but in some cases metadata_csum can still be valuable to detect corruption and avoid the use of corrupted metadata.
