[OpenIndiana-discuss] statfs() problem with HP-UX 11.23, 11.31 client and oi_151a server

[Albert Chin]

We're running oi_151a and using it to serve up file systems to HP-UX
11.23 and 11.31 hosts. Unfortunately, we're seeing statfs() problems
on this NFS server. We don't see this issue on any other client
(Solaris 2.6-10, AIX 5.1-7, HP-UX 10.20, 11.00, 11.11, Tru64 UNIX,
IRIX, RHEL 4-6).

With the following program:
  $ cat st.c
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>

#include <sys/types.h>

/* Tru64 UNIX */
/* #include <sys/mount.h> */

/* AIX, HP-UX, RHEL */
#include <sys/vfs.h>

/* IRIX, Solaris */
/* #include <sys/statfs.h> */

int
main (void) {
  struct statfs stbuf;
  int err;

  err = statfs ("/opt/dist", &stbuf);
  if (err != 0) {
    printf ("errno: %d\n", err);
    printf ("errno: %d\n", errno);
    perror ("error");
    exit (1);
  }

  exit (0);
}

$ uname -a
HP-UX yukio B.11.31 U ia64 1117140128 unlimited-user license
$ mount | grep /opt/dist
/opt/dist on sanji:/opt/dist/yukio rsize=32768,wsize=32768,NFSv3,dev=100042e on Sun Nov 27 06:39:33 2011
$ cc st.c
errno: -1
errno: 72
error: Value too large to be stored in data type

errno 72 is EOVERFLOW.

Trying to mount with NFS v2 gives the same result. Any ideas?
