Multicast won't start

Wayne Workman · Aug 11, 2016, 6:15 AM

@Towndrunk Well, that’s where it’s trying to send the multicast data to, and that will never, ever work.

Go here:
Web Interface -> FOG Configuration -> FOG Settings -> Multicast Settings -> FOG_MULTICAST_ADDRESS

And set that to 0 then restart the FOGMulticastManager and try again.

Towndrunk · Aug 11, 2016, 12:22 PM

@Wayne-Workman I believe that is where it was by default, and it wasn’t working. A co-worker made the change and it still wasn’t working, but he never put it back. I’ll put it back now and try again as soon as the update is done.

I went in to Image Management> Multicast Image and created a multicast with the following settings. I added one to the multicast and it was found and sat at the same screen, then added the second and it did the same. This is the same indication I have got in the past, however the log says that it is running.

Session: multi

Wayne Workman · Aug 11, 2016, 12:49 PM

@Towndrunk The multicast address is now completely missing from the command, did you set it to 0 or blank?

Tom Elliott · Aug 11, 2016, 12:50 PM

@Wayne-Workman Multicast address on the sender will only display IF the multicast address in the global settings is defined.

Towndrunk · Aug 11, 2016, 1:00 PM

@Wayne-Workman I set it to 0

FOG_UDPCAST_INTERFACE: eth0
FOG_UDPCAST_STARTINGPORT: 64148
FOG_MULTICAST_MAX_SESSIONS: 64
FOG_UDPCAST_MAXWAIT : 4
FOG_MULTICAST_ADDRESS: 0

Pascal Gazaille · Aug 11, 2016, 12:57 PM

@Wayne-Workman Hey sorry for the delay, I did what you wanted and tried to multicast 4 laptops this morning, it seems to work!

I’m gonna tried with more computer later today!

Wayne Workman · Aug 11, 2016, 1:00 PM

@Towndrunk Can you please try the below steps that I posted for the other guy now?

Pascal Gazaille · Aug 11, 2016, 1:03 PM

@Wayne-Workman Once the multicast job is done, is it supposed to disapear from the DB ‘multicastSessions’?

Wayne Workman · Aug 11, 2016, 1:04 PM

@Pascal-Gazaille It’s supposed to be marked as done, at least. There’s been work in this area, I’m going to defer to @Tom-Elliott on that question.

Tom Elliott · Aug 11, 2016, 1:05 PM

We’re at 1.3.0-RC-8, which I know addresses issues on multicast closing. This should be fixed now, so YES it should. NO need to defer, please update and see if all is well.

Towndrunk · Aug 11, 2016, 7:47 AM

@Wayne-Workman I went in and followed the steps listed below. I’m assuming that these are the steps that you were asking me to do?

mysql> DELETE FROM `multicastSessions` WHERE 1;
Query OK, 15 rows affected (0.00 sec)

mysql> DELETE FROM `multicastSessionsAssoc` WHERE 1;
Query OK, 2 rows affected (0.00 sec)

mysql> DELETE FROM `tasks` WHERE `taskTypeID` = 8;
Query OK, 42 rows affected (0.01 sec)

I then restarted the service, and tested again. I got the same results.

@Towndrunk Can you repeat the steps to clean the DB, then update to RC-8 (installing RC-8 will restart fog multicast manager as part of the upgrade), then try again?

Towndrunk · Aug 11, 2016, 7:57 AM

@Wayne-Workman I can do that. I am already running RC-8 though. I ran the upgrade this morning before doing the steps to clean the DB. If you want me to, I can repeat the process now.

@Towndrunk No, don’t bother then.

Is there a limit on how long you have to join the Multicast? I just tried another test and set it up for timeout of 10 minutes. I was able to get the first one added, however once I went to the second one it was not able to find the Session I created.

The odd thing is that if I send an image to any of these the individually I have no issues at all. I just assumed that the Multicast would be quicker if we were doing a group all at once. If I have to, I can just go back to doing them individually.

Multicast won't start
