"A journaling file system is a file system that keeps track of changes
not yet committed to the file system's main part by recording the
intentions of such changes in a data structure known as a "journal",
which is usually a circular log. In the event of a system crash or
power failure, such file systems can be brought back online more
quickly with a lower likelihood of becoming corrupted." -

ext2 isn't a journaling file system, while ext3 and ext4 are journaling
file systems.
