-h only display the superblock information and not any of the block group descriptor
-i display the filesystem data from an image file created by e2image, using device as
the pathname to the image file.
-x print the detailed group information block numbers in hexadecimal format
-V print the version number of dumpe2fs and exit.
You need to know the physical filesystem structure to understand the output.
