you reminded me of what i did not recall and after running command, i recall
why i do not use it. :=(
[geo@localhost Documents]$ tune2fs -l /dev/sdb3
tune2fs 1.41.12 (17-May-2010)
tune2fs: Permission denied while trying to open /dev/sdb3
Notice the pound sign prompt in my example? Yes, you have to run tune2fs
as root (or use sudo).
