ext4: How to account for the filesystem space?

The full 2 GB space doesn't get shown as free space even after fully formatting it with mkfs.ext4. Are these some system files which have occupied the space of 129 MB?

@Giles So this means that 129 MB are used for the file system storage? – Aquarius_Girl Jun 29 '11 at 07:30
Yes, 128 MB is for the journal, then usually there is a bit more for the resize inode. – psusi Jun 29 '11 at 13:03
@psusi The inodes take up more room than the journal. @Anisha You can see an example calculation in the post I've linked. Try running tune2fs -l /dev/sdb1 (or whatever the device is), and checking if the calculation works out. Also make sure you're interpreting the output of df correctly, if that's what you're looking at (see also What happened to my free space). – Gilles 'SO- stop being evil' Jun 29 '11 at 13:55
@Gilles yes, but the inode tables are not counted as "used space". – psusi Jun 29 '11 at 17:43
