ext2 vs journaling.


Hi:
In one of the windows of setup, the program one runs when installing the slackware 14.0 OS, namely "Select filesystem for /dev/sdXN", where X is some letter and N is a number, Volkerdi says:

Ext2 is the traditional Linux file system and is fast and stable. [The "underlining" is mine]

If he himself is telling me this, why should I choose a journaling filesystem as ext3 or ext4?

Slackware 14.0

he? He's not a deity... maybe you'd do well do not feel that you're going against the lord almighty in cases like this.

Ext3 is just as fast as ext2 as it's the same thing with journalling added on the side. If you don't plan on ever crashing or having a powercut etc., then sure, ext2 is fine. I presume that the language used is really as a contrast to other filesystems outside of ext

Two things: how much more space does ext3 use over ext2? Double? 1.5 the space ext2 needs? The second: methinks its an illusion to anticipate no powercuts. I mean, they can come at any time and even your UPS can fail. But then there would nobody left using a non journaling fs like ext2! But probably that's the case.

The fact is that I am just at the point in the installtion where I have to choose one or the other and I expected some elements of decision.

double the space??? of course not, the journal is in the filesystem metadata and uses an utterly negligible amount of data.

There are other filesystems like JFS and XFS that are just as stable if not more so, and have good performance but less than ext4 or btrfs.
