== Comment: #0 - MANAS K. NAYAK <maknayak.com> - 2013-05-27 04:15:57 ==
Executing "dmeventd -d " from terminal on Fedora 19 P7 installed LPAR, noticed child gets exited with code 1.
Last command exit status also shows 1.

[root@miz12 ~]# dmeventd -d
Child exited with code 1
[root@miz12 ~]# echo $?
1
[root@miz12 ~]# dmeventd -ddd
Child exited with code 1
[root@miz12 ~]# echo $?
1

Even if for checking version , exit status shows 1.
[root@miz12 ~]# dmeventd -V
dmeventd version: 1.02.77 (2012-10-15)
[root@miz12 ~]# echo $?
1

Hi Manas,

# daemons/dmeventd/dmeventd -V
dmeventd version: 1.02.77 (2012-10-15)
# echo $?
0
# kill -9 28149

dmeventd version: 1.02.77 (2012-10-15)
# echo $?

I think - the 'dmeventd -d' o/p run the second time must exit with exit status 1. Please correct me here. 
Why would anyone like to run 'dmeventd -d' when there is already a 'dmeventd -d' running ? 

Now, I agree with you that  dmeventd -V must  *always* return exist status 0 - and it does so (see above results) irrespective of the fact that the dmeventd daemon is running/not running.  Please find the patch attached for these results.

Please let me know if these results are acceptable.

Regards, 
Onkar

Yes, that must return 1 to indicate failure here as only one instance should be running at a time.

Yes, that should be return 0. Thanks for spotting this! Committed upstream.
