UDP Does not start on Multicast

[Critchleyb]

Hi,

I’m attempting to test Multicast in a lab environment. I followed the steps on https://wiki.fogproject.org/wiki/index.php/Multicasting#Device_Configurations to test Multicast and they all transfer successfully.

However when I try to Start a Multicast Deployment from the GUI, the UDP service does not start and the PC’s just boot into partclone and don’t show a progress bar.

This is the command im using to check UDP

ps ax | grep udp
5386 pts/0 S+ 0:00 grep udp

In the multicast.log, nothing logs when i try to start a session, however “This is not the master node” is repeated every 10 seconds

The setup has only a single storage group which is checked as the master.

Advice appreciated!

@Critchleyb Take a look here. Guess you have the same issue: https://github.com/FOGProject/fogproject/issues/268

Thanks,

Reading your conversation through to understand a little more which services multicast uses was helpful. I was able to just restart the “FOGMulticastManager” service and the deployment started successfully.

@Sebastian-Roth I restarted the server and can confirm that I’m having the same issue as brnnrc.

I’m using Version 1.5.5 on Debian 9.

I’ll have a look at implementing the fix you suggested there so that I don’t need to restart the service on startup each time.

@Sebastian-Roth It seems to work. I do get a single line of “This is not the Master Node” on reboot but then it jumps back to no new tasks, see Below:

@Critchleyb Good to know you could work around the issue as suggest in the issue ticket on github. I will see what I can do to properly fix this. Will surely be fixed in the next release.
