I think there's something very strange going on with fsck and ext4:
fsck -f /dev/sdb3
fsck 1.41.3 (12-Oct-2008)
e2fsck 1.41.3 (12-Oct-2008)

Lagring: 602/13238272 files (114.6% non-contiguous), 6442136/52934175 blocks
df -h /dev/sdb3
Filesystem Size Used Avail Use% Mounted on
/dev/sdb3 199G 22G 178G 11% /home/arch/Lagring
I'm running kernel 2.6.28-2. I created the filesystem with
mke2fs -T ext4 -m 0 /dev/sdb3
.
Does anyone else have the same problem? Or perhaps I have missed something when I created the filesystem, or perhaps the version of fsck can't handle ext4?

I created a new filesystem and ran fsck on it without any files, and it returned 0.0% non-contiguous as expected. I then copied over some files from a ext3 partition to it (100MB) and fsck gave over 100% again. I'm thinkin it have something to do with the use of extent perhaps?

It might be worth bringing this up on a relevant mailing list or googling for similar things.

I've planted 60 GBs of files onto a root ext4 partition and cannot reproduce this problem. I get about 1.3% non-con. I left it its 5% root reservation space though but I'm uncertain if that has anything to do with it.

Perhaps something I wrong with the version of my packages. Did you install kernel26 from extra (and also what other packages)?

Did some experimenting with my ext4 partition. It seems that the problem only occours with some of the files on my computer. I can't seem to find any pattern either (tried filetypes, sizes etc). Some files give 0% non-contiguous after transferingthem to ext4, while others gives over 100%.
