Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A journaling file system is a file system that keeps track of the changes that will be made in a journal before committing them to the main file system. In the event of a system crash or power failure, such file systems are quicker to bring back online and less likely to become corrupted. Updating file systems to reflect changes to files and directories usually requires many separate write operations. This makes it possible for an interruption between writes to leave data structures in an invalid intermediate state. If a crash occurs between steps 1 and 2, there will be an orphaned inode and hence a storage leak. On the other hand, if only step 2 is performed first before the crash, the not-yet-deleted file will be marked free and possibly be overwritten by something else.
