Fuser on VXFS not reporting processes
I have a perl script like :
Code:
#! /usr/bin/perl
open FILE1,">/tmp/openfile.test.out";
open FILE2,"</tmp/openfile.test.in";
open FILE3,">/data/openfile.test.out";
open FILE4,"</data/openfile.test.in";
        <STDIN>;
close FILE1;
close FILE2;
close FILE3;
close FILE4;

  • /tmp is jfs2
  • /data is vxfs
Fuser does not report processes on /data/openfiles.test.in where it does report a processid on /tmp/openfiles.test.in

Code:
 # fuser /tmp/openfile.test.in /data/openfile.test.in
/tmp/openfile.test.in:  1507428
/data/openfile.test.in:

Are there known problems with fuser on vxfs?

The system is running AIX5.3 in a LPAR.
/data is a SAN disk that is offered by a VIO to the LPAR.

Addition: I found that procfiles does see the open file but cannot stat the file name.
Code:
procfiles -n 675910
675910 : perl openfile.pl
  Current rlimit: 2000 file descriptors
   0: S_IFCHR mode:00 dev:10,4 ino:1181 uid:0 gid:0 rdev:19,1
      O_RDWR  name://dev/pts/1
   1: S_IFCHR mode:00 dev:10,4 ino:1181 uid:0 gid:0 rdev:19,1
      O_RDWR  name://dev/pts/1
   2: S_IFCHR mode:00 dev:10,4 ino:1181 uid:0 gid:0 rdev:19,1
      O_RDWR  name://dev/pts/1
   3: S_IFREG mode:0444 dev:10,7 ino:446 uid:0 gid:0 rdev:0,0
      O_RDONLY size:0  name:/tmp/openfile.test
   4: S_IFREG mode:0444 dev:34,3000 ino:8 uid:0 gid:0 rdev:0,0
      O_RDONLY size:0  name:Cannot be retrieved
