Hi.
I've had several crashes recently, which lead to things like these:
May 6 00:23:53 heisenberg kernel: [ 31.941036] EXT4-fs (dm-2):
ext4_orphan_cleanup: deleting unreferenced inode 2016253

... and some (at least to me) worrying questions during fsck.
However, I constantly get these errors:
[ 331.744025] EXT4-fs (dm-2): error count: 10
[ 331.744030] EXT4-fs (dm-2): initial error at 1304673122:
ext4_mb_generate_buddy:731
[ 331.744034] EXT4-fs (dm-2): last error at 1304673124: ext4_remount:4250
... (probably) when reading some files. I guess it's reading files, at
least it happens during a debsums run (checks the package sums of more or
less all Debian packages installed).
Also the numbers in the errors above, are (at least until know, and as far
as I looked after it) the same.
It also happens (as far as I can see) only once, i.e. if the error has
already occurred, and I do e.g. my debsums again, it's not printed again.
fsck runs through fine (but quite quick; yes - of course - I've used -f)
Any ideas? (Please CC me as I'm off list).
Cheers,
Chris.
btw:
This (occuring in the host's kernel log and not the VM's)
[ 325.655192] EXT4-fs (dm-2): Unaligned AIO/DIO on inode 1060986 by
VirtualBox; performance will be poor.
means that the blocks of the the guest are not aligned to the blocks of
the host, right?
But why is it only printed once?

Kernels 2.6.35 and newer will set superblock fields that will result
in those messages. They're not error messages per se; it's just a
notification that there was an file system error in the past that
hasn't been fixed yet. In your case, it *has* been fixed, but you
don't have a new enough version of e2fsprogs so that it clears the
relevant parts of the superblock.
The debian packages of e2fsprogs version 1.41.14-1 in experimental, or
1.41.12-4 in unstable, has the necessary new code in e2fsck. I'm
working on getting the patch pushed to Debian obsolete^H^H^H^H^H^H^H
stable; hopefully that will happen in the next week or two.

Thanks for that explanation.

Ah, I haven't tried it with the one that was uploaded to unstable
yet.... will give it a try later.
Another thing. Perhaps you've seen my post where I've unfortunately
overridden an (important ;) ) ext3 fs with mkfs, instead of doing fsck.
Of course this is my fault but do you see any chance to add checks to
mke2fs whether any known fs/partition type/other containter like
luks/mdadm/etc. is on the device? (And of course require a
--force=I-really-know-what-I-do™ parameter to the evil.)
Cheers,
Chris.

The problem at least persists in the 1.41.12-4 version.
Cheers,

Um, are you sure? Try forcing an fsck run on the file systems in question.
