Difference in output of 'dumpe2fs -h' versus 'tune2fs -l'
Below is a copy of descriptions of the two discussed operations from their manpages:
tune2fs -l:
List the contents of the file system superblock, including the current values of the parameters that can be set via this program.
dumpe2fs -h:
only display the superblock information and not any of the block group descriptor detail information.
The output of these two commands is equal, except that dumpe2fs -h prints additional 9 journal-related lines of information at the end, at least that is the case with ext4. I believe this information might also be useful in tune2fs -l, especially the first 3 lines:
Journal features
Total journal size
Total journal blocks
