lsof output

[icecubegr]

Hi,

I want to find the opened files for a process. I type the command lsof -p pid but I have the following problems:
1. Instead of getting the real file name, I get the file system name.
2. The inode file for files in a specific file system is '0', but for other file system are displayed.

== Example ==============================
$lsof -p98778
lsof: WARNING: compiled for AIX version 5.1.0.0; this is 5.3.0.0.
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
jsh 98778 r07close cwd VDIR 42,4 0 0 /gl (/dev/fslv01)
jsh 98778 r07close 1w VREG 42,4 0 0 /gl (/dev/fslv01)
jsh 98778 r07close 3u VREG 42,2 21120 108577 /db5 (/dev/lv00)
jsh 98778 r07close 4u VREG 42,2 0 108579 /db5 (/dev/lv00)
jsh 98778 r07close 6u VREG 42,2 87 92161 /db5 (/dev/lv00)
jsh 98778 r07close 11u VREG 42,4 0 0 /gl (/dev/fslv01)
===========================

Can anyone help me on those problems?

Regards,
George

Hi George,

I just wanna say that i have the same output as yours as well! Never though of why to be honest!

I usually refer to this link for the lsof explaination! it seems that there are something missing!

http://www.ibm.com/developerworks/aix/library/au-lsof.html

I will be looking into this and will let you know once i find something related!

Thanks for bringing this out!

Regards,
Khalid

Could it be for this reason?

lsof: WARNING: compiled for AIX version 5.1.0.0; this is 5.3.0.0.

coz mine shows the same warning message! I guess we both have the same version of lsof!

Ok i just had a work around!

# lsof /usr | more
lsof: WARNING: compiled for AIX version 5.1.0.0; this is 5.2.0.0.
COMMAND     PID     USER   FD   TYPE DEVICE     SIZE/OFF NODE NAME
inetd     20538     root   19r  VREG   10,5   4295131556    0 /usr (/dev/hd2)
errdemon  21780     root    3r  VREG   10,5   4295131556    0 /usr (/dev/hd2)
cron      23954     root    3r  VDIR   10,5  17179951615    0 /usr (/dev/hd2)

So i took the first PID 20538 and used the ps command to get the file opened by this PID:

# ps -ef | grep 20538
    root 20538 23008   0   Sep 28      -  2:01 /usr/sbin/inetd 
    root 87140 20538   0 08:58:41      -  0:00 smbd 
    root 94752 20538   0 15:12:17      -  0:00 telnetd -a 
    root 96204 95256   0 09:59:26  pts/3  0:00 grep 20538

I think it is because of the old version of lsof as it shown here:

I just got the latest lsof version for aix5.3 from here:

http://www-aix-old.gsi.de/~bio/DOCS/AIX/aixpdslib.seas.ucla.edu/packages/lsof.html

and i still have the same output as yours!!! I'm not sure if this is how it should be! I just thought of updating this thread!

Hi,

I am not sure because I am just a programmer and not the admin in the server, but I have noticed something strange. The one displaying the inode is logical volume, but the other one is possibly file system under logical volume. Maybe this is lucky... maybe not.
