What is the journal?
I shut down my computer the hard way and next startup there was message on boot for several seconds saying recovering journal. Four startups later and the message was not there - only the first time. Looks like there are no consequences or side effects. Thanks to this question I know why it happened but nowhere on the internet says what the journal is. There are no problems with it, I'm just interested in what it is.

Does someone knows what journal is?
Part of a modern day filesystem is a feature called "journaling". We use "ext4" as a filesystem. (ext3, ext2 are older versions. NTFS is a Microsoft equivalent.)
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
Source: Wikipedia - Journaling file system, cites: IBM - Anatomy of Linux journaling file systems
Basically the message means the system did an integrity check on this part of your filesystem. It is forced by the system, so generally there is nothing to worry about. When you have power cutoffs, the journal can get damaged and, unless your harddisk is really busted, tends to get repaired during this check.

Is it correct to say, that journaling is used to protect the filesystems integrity, but not necessarily the integrity of the files (their content)?
