The journaled file system (JFS) maintains a log, or journal, of what activity has taken place in the main data areas of the disk; if a crash occurs, any lost data can be recreated because updates to the metadata in directories and bit maps have been written to a serial log.
Files written (created or modified), during a system crash, can be corrupted if not closed when the system shuts down. Using a journal allows data recovery of files and the data within it. What occurs during the journaling process is that a user submits a change to a file. The first thing the file system does is to mark the changes in a 'journal', or a separate file used specifically for journaling.
