Multicast not starting
-
@Tom-Elliott yes
Service FOGMulticastManager status is Ok -
@gerald.stachl Can you post the /opt/fog/log/multicast.log file?
-
I’ve added some code to more dynamically get the master interface so we don’t continue to have these issues (hopefully).
Basically, what my latest commit does, FOG will no longer need the Storage Node interface being set properly for our multicast tasks to operate. It will attempt to figure out which interface to use based on the host/ip of the storage node master. With any luck, this will mean no more of the lost udp sessions, though I can’t be 100% sure it won’t still cause issues. I’m relatively certain this change should help us with at least not losing the process that performs the tasking.

I did the update via git - still same situation.
Where are the main config files now? /opt/fog/services/etc/config.php has only a definition of WEBROOT
-
@gerald.stachl Just a basic question here, you know that when you do a
git pull
to update your fog installation files, you then need to re-run the installer correct? You can run it like this:./installfog.sh -y
-
@Wayne-Workman
Yes. After “git pull” i did
./bin/installfog.sh
passwd fog (i use a different PW for the fog user) -
Do you actually see the FOG services running on the server?

On this server, unicast imaging works fine. I had some problems with the FOG Client - i had to change back to the legacy client, because the domain join didn’t work with the new client (but it worked some weeks ago - but this might be a different problem)
-
@gerald.stachl is the OS this is installed using systemd or sysvinit? If systemctl can you get output of
systemctl -l status FOGMulticastManager
? If sysvinit can you get any information from the Apache error logs? -
Yes, there are a lot of error messages. 10.2.2.83 is the IP of the client i try to multicast. Seems that there are problems with DB connections? - (Correction: i saw, that these errors are from yesterday: maybe when i truncated the mysql multicast and tasks tables?)

@Tom-Elliott
i just found something in syslog:
- not sure if this is correct. The errors above come from samba, because SAMBA4 is also installed on this server.
-
@gerald.stachl rpc is nfs. tftp is well, tftp. Can you update to the latest, again, please.
-
@Tom-Elliott
Did the Update (7701)
At the moment there is an error in management interface -
@gerald.stachl Update again, but also do a hard refresh on the page.
-
@Tom-Elliott
Did both, the error on the task management page is gone, but still the same error when trying to start multicast. -
@gerald-stachl said:
same error when trying to start multicast
Which error? The ones you posted from the apache log don’t seem to be related to multicast!
-
@Sebastian-Roth
I mean, that multicast is not starting. In apache error log there are lines like “[client 10.2.2.83] PHP Warning: array_map(): An error occurred while invoking the map callback in /var/www/fog/lib/fog/fogcontroller.class.php on line 197”
There is another thread with similar error in logs:
https://forums.fogproject.org/topic/7412/problems-with-multicast-task/23 -
@gerald-stachl Ok, thanks for clarifying! I am calling @Tom-Elliott as I refuse to try to debug this kind of code (nested array_map calls). Sorry Tom, but this will be all yours…
-
@Sebastian-Roth Error throwing is due to array_map not being able to handle “throw new” from within. I’ve adjusted all functional programming within the fogcontroller.class.php file to array_walk in hopes to fix the issue. I don’t know if it will fix the “mutlicast not starting” issue.
-
@Tom-Elliott
The array_map() errors are gone now, but multicast is still not starting:
I can’t find any errors in apache logs now. I also wonder, why there is no multicast.log file? (i had a file, but this file was created during test with udp-sender on the console)
I cleared the folder /opt/fog/log and ran the installer again. After that the Service Master Logfile is created new, but all the other logfiles don’t exist:in the Service Master Log i can see:
[05-19-16 4:40:11 am] FOGPingHosts child process (27579) exited with code 255.
[05-19-16 4:40:09 am] FOGTaskScheduler child process (27578) exited with code 255.

[05-19-16 4:40:03 am] FOGMulticastManager child process (27575) exited with code 255.(is that OK?) - The timezone in the logfiles seems to be UTC, even if i correct the timezone settings in php.ini. The system time (date) also shows the correct time.
Any other debug options i could use?
