[Message part 1 (text/plain, inline)]

(please CC)

Hello, I'd like to report a bug/regression in du's behavior, where it
returns Infinity (exit status 0) with the -s option.

Version:
$ yaourt -Qo /usr/bin/du
/usr/bin/du is owned by coreutils 8.21-2

Archlinux, [testing] repo.

Output:
$ du -s ~
Infinity        /home/marek

Thanks, Mark

What's the relevant output of 'strace du -s ~'?

Ok, I tracked it down a little.

The 'Infinity' is correctly inherited from subfolders all the way up, it
boils down to a single .xml file, which claims to be 16 exabytes, it
obviously isn't :)

$file .. on the file is correct and says 'data',
$vim can open it and shows some binary... (binary in .xml?)

The FS is btrfs (with lzo compression), no failures noticed, nothing
interesting in dmesg.

Follows the strace on the offending file,
Thanks, Mark

This is one of the key system calls, but it's lacking
crucial details.  What does strace -v say for that syscall?
strace -v should give info about st_blksize and st_blocks.

Maybe it's file system corruption?
What does fsck say about the file system?

Hi, thanks for advice and sorry for the delay, I went in wilderness off the
internet.

it reports lots of blocks (btw, i tried defrag in btrfs before).

Regarding running fsck, well, it's btrfs, so the fsck is not so matured
yet...what can i run for testing? Yet, no errors with the FS are
reported/observed.
..it must have been a FS corruption, a cp -a (to /tmp on tmpfs), rm, and cp
-a back cycle solved it.

$  strace -v du  ~/.kde4/share/apps/kopete/logs/JabberProtocol/....
