ext3 file system logs changes to a journal before actually writing them to the main file system. It use that log files to repair any inconsistencies that occur as the result of an improper shutdown of a server.

ext2 takes more time to repair file system as compare to ext3.

You can run dumpe2fs program to see more info. For example
Code:
dumpe2fs /dev/sda1
You can use tune2fs command to adjust and see journal file which is usually not available to naked eye. Be careful with these command. Wrong usage can result into data loss.
