SVN 7088 Multicast not working...hanging at partclone. This did work before.

[Tom Elliott]

What’s in the Multicast Log file.

[Sebastian Roth]

@Hanz Maybe restart the FOG services? Unfortunately the clients won’t pick up the running multicast session, so you need to shut them all down and start over again.

[Hanz]

@Sebastian-Roth I repeat deleting tasks from mysql and taskID =8 and then systemctl restart FOGMutlicastManager after each failure and before trying again.

@Tom-Elliott Below is from multicast log

[04-05-16 1:41:23 pm] | Task (5) Multi-Cast Task is already running PID 6347

This is from Service Master log

[04-05-16 1:35:29 pm] FOGMulticastManager fork()ed child process (1573).
[04-05-16 1:35:29 pm] FOGMulticastManager child process (1573) is running.
[04-05-16 1:35:29 pm] FOGImageReplicator fork()ed child process (1569).
[04-05-16 1:35:29 pm] FOGTaskScheduler fork()ed child process (1572).

I also wanted to note that I have a multicast.log.udpcast.5 that is empty, along with the multicast.log

Tom has verified that regular multicast is working from server; however I have 4 additional (master nodes) at different locations seperated by vlans, but I got iphelper added to router, and have had this working at this location before.

@Hanz You probably have to kill the udpsender process as well?

[Hanz]

@Quazz That I didn’t do, but I 'll try it

[Tom Elliott]

@Hanz Any info on this?

[Hanz]

@Tom-Elliott I’ll try it out tomorrow, updating today

[Tom Elliott]

I know I keep nagging, but any information?

[Hanz]

@Tom-Elliott my apologies meetings all day today, probably tomorrow as well. I only have one school (15 miles away) with multicast enabled via router.

[Tom Elliott]

@Hanz Anything on this yet?

[Tom Elliott]

Buehler?

[sudburr]

@Tom-Elliott LOL … That made my Monday …

[Tom Elliott]

@Hanz Elvis?

@Hanz 2pac?

@Hanz Jimmy Hoffa

[sudburr]

Buehler is still the best.

[Hanz]

@Tom-Elliott I’m terribly sorry, my wife needed me more than this here. I have been staying with her and apparently my pushbullet isn’t working so I haven’t seen your latest comments. My apologies, I will be back at work this week and gone for another, but I will try again…Am I the only one that has this setup in such a large environment ?

No I am sure we have others with similar large setups! As this has been around for a months without much new information and we solved most of the latest multicast issues with other users I am going to move this to the problem section. Please don’t get me wrong. I am very interested in finding out where the problem is with this. But as we don’t have others reporting a general multicast issue from 7088 upwards I kind of doubt this being a bug in FOG - although I might as well be wrong. Feel free to move it back if you can give us more solid information. For example full multicast.log as well as ps ax | grep -e udp -e FOG when partclone is waiting.
