Multicast without registration starts OK, but hangs and disconnects clients due to timeout.
-
@george1421 The switch is a Nexus 9372TX, but my network guy is onsite now and he told me the switch (the Nexus) in the test lab is not our POR in the main rack space where this solution will ultimately be deployed so he’s going to swap it out (with a Catalyst we use in our prod lab) and we will retest and update this thread with our results.

Same issue as before… In the meantime is there anything else I can try from my end?
Ok, looks like it’s not the hosts/clients. You might want to try manual multicast deployment testing along these lines: https://wiki.fogproject.org/wiki/index.php/Multicasting#Something_else_to_try
I have to say that have not done this myself in a long time and I am not exactly sure if the commands are still used exactly like this in FOG. Give it a try with the second partition (that seems to be more problematic than the first one) and let us know if you need assistance with the commands.
-
@Sebastian-Roth I will add this to the list of testing after the switch is swapped out for the prod Catalyst if I am still having issues.
-
@jmvela2x Multicast appears to be working after swapping out the switch. I was successfully able to image two clients concurrently sans registration (this is important to the solution as host registration would cause us a lot of extra work) in our environment.
I did notice the task is still showing in active tasks and has not cleared out. Is that an issue you are aware of?

This is a known issue in FOG 1.5.8 and should be fixed in the latest development version. You are more than welcome to update to 1.5.9-RC1 or even the current developer version as we are reliant on people actually testing the release candidate version to find bugs we can fix before the next release.
Best way is to use git:
sudo -i git clone https://github.com/FOGProject/fogproject/ cd fogproject git checkout dev-branch cd bin ./installfog.sh -
@Sebastian-Roth I’ll give it a shot tomorrow and let you know. What the timeline one a new version making it from RC to an actual official release typically?

I have to say that we don’t have a strict release cycle established yet. The amount of people testing and reporting bugs is unpredictable and so it’s hard to predict how many bug reports we get and when. It also depends on how serious bugs are (hard to fix or easy going) as we are a small team of developers and how responsive bug reporters/testers are. I would hope we get the next release out by end of May.
-
@jmvela2x I updated to 1.5.9-RC1.4, changed line 662 per your earlier instructions and tried to kick off a multicast task. The log shows the task start, then completed, then killed, then completed again, and then removes itself from active tasks. This seems like step backwards. Am I missing something?
-
@jmvela2x Can you please post the relevant part of the log here?

@jmvela2x I didn’t even have the chance to join the clients to the session.
-
@jmvela2x I see something potentially relevant in the status output of the FOGMulticastManager service.
“PHP Warning: proc_get_status(): supplied resource is not a”(vailable) I presume is the ending, but it’s cut off in the terminal.
-
@Sebastian-Roth I may have an opportunity coming up soon to test this in our production environment, but without multicast working in 1.5.9-RC1.4 I will lose the chance. Barring some kind of fix in the very near future for this issue, can you advice on how to roll back to 1.5.8 so I can at least test functionality of multicast cross-subnet in terms of bandwidth usage, etc when the opportunity presents itself?
-

This can only happen if your subnet router supports igmp proxying or you have a mrouter in place to manage the multicast traffic. Multicasts will not normally traverse a normal router.
-
@george1421 I’m pretty sure we’re covered on this front, but I will run this by our network guy.
-
@jmvela2x I am sorry but today has been a very busy day und I could not find the time to look at this yet. I will do so first thing in the morning!! I don’t recommend you to roll back to 1.5.8 just now.
-
@jmvela2x Just a quick note on this. Now that I think more about it I am fairly sure I did test multicast once before pushing out the RC1 release. So I wonder if this could be a hickup on your FOG server? Did you try to clear all tasks, restart the FOG server and then schedule a fresh multicast task yet?
Is this multicast scheduled through a group in the FOG Web UI?
-
@Sebastian-Roth I did try several reboots and cleared all the tasks each time to make double sure. The multicast session is being scheduled from the Images tab with a defined client count as we are trying to avoid host registration as the hosts in our environment are not static per se. The amount of work required just makes FOG an nonviable solution for us if have to do host registration for all our clients.
-
@Sebastian-Roth I will hold off on changing anything until I hear from you tomorrow. Thanks for the follow up.
-
@jmvela2x Good news and bad news. I found the issue but I still need a bit more time to debug and fix it. It’s getting late and I need to rush to work now. Please stay tuned and I will update as soon as I can.
