Error in du running on Linux for a mounted HP-UX filesystem

[Jens Liebehenschel]

Dear developers,

I want to report an error in the du (disk usage) program.

Configuration:
--------------
SuSE Linux 7.1, Kernel 2.2.18
Mounted filesystem from HP-UX 10.20
du Version: ?, but in the manpage I found:
--- cut ---
GNU fileutils 4.0.35, December 2000
--- cut ---

Error description:
------------------
du reports on HP-UX mounted filesystems (I tried the parameters h, b, c
and m) only about the half of the size of the file(s) in consideration. I
used du on the Linux box with a mounted filesystem from HP-UX. On local
filesystems, du reports the correct size.

Example:
--------
> ls -l file
-rw-------    1 jens     sads        20250 Jun 12 12:52 file
> du -h file
10k     file
>

Remark:
-------
On Suse Linux 6.2 (kernel 2.2.10) the error does not occur; in the manpage
of du on a Suse Linux 6.2 System I found the following text:
--- cut ---
On BSD systems, du reports sizes that are half the correct
values  for files that are NFS-mounted from HP-UX systems.
On HP-UX systems, it reports sizes that are twice the cor­
rect  values  for files that are NFS-mounted from BSD sys­
tems.  This is due to a flaw in HP-UX; it also affects the
HP-UX du program.
--- cut ---

So, perhaps the correction of this error implied a new error in the
version of du that I use !?

I hope the report is detailed enough. If you need some more information,
please feel free contact me !

Regards
   Jens
