Ext4 question - 'EXTENT_FL set, not in extent format' msg.

[Pse]

So, I know I've seen this somewhere, probably a thread here, but I've run a couple of searches and found nothing. I'm running root (/) on ext4dev and e2fsprogs-1.39-r1 (yeah, I know it's broken) and forgot to disable the automatic check during boot. So, e2fsck was run on my root partition and a countless number of messages such as this one were shown:

Hi Pse,

I have the exact same problem since the day one I started using ext4dev but haven't found a solution to that yet. I have tried using different kernels & different sources of patched e2fsprogs but with no luck whatsoever. As long as I write smth to disk after I have format it an mount it with '-extends' option, all the fscks after that give me alike errors. Sometimes after using the fs for a period I might end up with some duplicate files as well after an fsck (in the form *~*) but haven;t lost any data yet. Anyway I have to admit it a bit annoying.

If you (or anyone else ) has any idea please share it !!

Hi again,

After some testing it turns out that the problem should have smth to do with the livecd used to format ext4 partition initially. I could think either of the kernel or the version of e2fsprogs. I used to have the same problem for some time know with both my / and /home partition. The live cd I had used to format them was small-gentoo x86-r9. I recently reformatted my /home partition again but this time from my running pc and it turns out that problem has gone. I am currently running klight sources2 (ext4-updates-2.6.21-2.patch) and using e2fsprogs from here http://kernel.org/pub/linux/kernel/people/tytso/e2fsprogs-interim/LATEST/.

Hope that helps a bit.

Hi, thanks for the heads up! I'll probably reformat my / partition in a couple of days with a new kernel and see what happens, thanks a lot
