2Gb file size limit on 2.4.24, LVM and ext3?

[Niccolo Rigacci <niccolo@rigacci.org>]

Hi to all!

I got a very strange problem: I can create files larger than 2
Gb (even 5 Gb), but I can't read them back.

- The simple "cat" command fails with:
  # ls -la pippo
  -rw-r--r--    1 root     root     2147483648 May  6 17:03 pippo
  # cat pippo
  cat: pippo: Operation not permitted

- A file just 2kb under 2Gb, reads fine.

- If I do an "strace cat pippo" it works fine! So how can
  I trace the problem further?

- The partition is an ext3 over LVM, kernel 2.4.24. Debian Woody
  (glibc-2.2.5-11.5). Pentium 4 2.80GHz.
  I tried both a quoted filesystem and a non quoted with same
  results.

- On a very similar system I have no problem, the main
  difference is using LVM here.

Is there a known issue? Can someone tell me how can trace down
the problem?


Many thanks!

Please CC to me if you can.
