Hi dudes,
I was wondering about defragmentation under Linux. Probably it's a stupid thing... But how does it work with ext3 and xfs? Answer me if it simple or redirect me to the documentaion.
Thanks.

;-)

Linux file systems don't need to be defragmented because they're 'smarter' at laying out files than file systems used by other operating systems.

The FSs are smarter, but a small amount of fragmentation *does* occur. Fortunately, the filesystem drivers intelligently defragment fragmentation "on the fly" so your fragmentation rarely exceeds 0.7%

Hello,
I have been using linux for a short while now, and I have been wondering if there is such a thing as a defrag program for linux? I can't see why there wouldn't be something of this nature for linux...

Well, if there isn't such a program, could someone please explain how linux maintains the fragmentation that occurs on the harddrive...

Thank you,
Mike Rhodes

There is an old ext2/minix defrag utility, and I'm guessing it would work on ext3 also.

Would' that be a waste of time because most linuf filesystems get a low amount of fragmentation?

The filesystems are fine without manual defragmentation, and there's usually a negligible performance increase from running it, so it's probably just a waste of time.

I have never tried the application, but delta407 is correct IMO.
