Hello,
I'd like to read superblock's information on Redhat 7.3,
but I don't know how to do it.
For example,
Input : "/dev/sdj2"
Output : ext2_super_block struct's s_wtime
(I saw it at "/usr/include/ext2fs/ext2_fs.h")
Input : "/dev/sdj1"
Output : ext3_super_block struct's s_wtime
(I saw it at "/usr/include/linux/ext3_fs.h")
Please give me an answer...

For example: # debugfs /dev/hda1 debugfs: show_super_stats -h Filesystem volume name: /boot Last mounted on: <not available> Filesystem UUID: bd9fc6d2-4102-4328-91af-g257964e513b Filesystem magic number: 0xEF53
