On ext3 and ext4 filesystems it's stored either in the journal inode (the default) or on a separate device, depending on the options passed to mke2fs.

Could you please explain me where the journal inode is? – Sen Nov 25 '10 at 9:32
Same place as all the other inodes: on your hard disk. – Ignacio Vazquez-Abrams Nov 25 '10 at 9:40
@Sen: data is stored on inodes. some inodes are made visible to the user via "names" (thats what you actually see). some inodes do not have a visible name. the journal inode is such an invisible one. – akira Nov 25 '10 at 9:48
