Description
Fresh install of Version 1.3.0-RC-15, upgraded to Version 1.3.0-RC-16. I was having the issues
https://forums.fogproject.org/topic/8833/can-image-individual-host-but-not-group-location-plugin/4Upgraded to 1.3.0-RC-16, and it does resolve the image issue. However a new multi-cast task issues is seen.
I click the multi-cast button on a group of 5. I confirm my selection. On the Active Task screen I see the multi-cast deploy task for all 5 of the hosts. If I click the “Active Multicast Task” link, there are no multi-cast task.
When I boot these host, they complain:
Invalid Multicast session -
-
I guess I’m not understanding.
You’re trying to do what I call a “Named” session for multicast?
-
This post is deleted! -
No, just an ordinary multi-cast to a group. At least I don’t think so, it never prompts me for a name for the task.
I click Group Management, then I click click “List all Groups” then I click the Multi-cast button in the “Tasking” column.I can image the host individually with the Deploy button in the Tasking column, but Multi-cast fails.
-
Well I’m testing a named session right now.
I’ll follow right up with a group deploy session.
I’m only using a single host to manage it at this point though (as it’s all I have readily available to test with at the moment).
-
I’m not seeing a problem in all three situations so far.
Three being:
- single host multicast from list/search deploy multicast
- group multicast
- Named session multicast.
Can you provide the multicast logs for say the last 500 lines?

@rbaldwin Do you have more than one node?
-
no, this is a single server installation.
Here is some information that you might find handy:
When I create a multi-cast task. I see a new entry added to multicastSessionsAssoc table in the DB
For example the below is me trying to create a single host multicast session(as a test)
select * from multicastSessionsAssoc;

±------±-----±----+
| 43 | 0 | 70 |
±------±-----±----+
1 row in set (0.00 sec)I see an entry added to tasks table in the DB
mysql> select * from tasks where taskid=70;

1 row in set (0.00 sec)Nothing is added to the multicastSessions table
select * from multicastSessions;
Empty set (0.00 sec) -
Can you try:
rm -rf /var/www/{html/},fog
Rerun the installer.
From within mysql run:
truncate table multicastSessions; truncate table multicastSessionsAssoc; delete from tasks where taskTypeID=8;
Then retry?
-
@Tom-Elliott I’d suggest doing the MySQL commands before deleting the web directory and reinstalling. That way when the multicast service restarts there’s literally nothing in the db about multicast from the git-go.
Also, there is this:

@Wayne-Workman
Thanks, I’ve looked at that, that’s what got me looking at the DB and what changes when I create a task. I assume when I create a multicast task, it should be added to the multicastSessions table and the task should show up in the WEB interface under Task Manager > “Active Multicast Tasks”@Tom-Elliott
Okay, I did that. Same result.So next I dropped the fog database entirly in mysql with “drop database fog;”
Removed the /var/www/html/fog folder with “rm -rf /var/www/{html/},fog”
and re-ran the installer.
Same result… When I create any multicast task, no multicast task is shown in Task Manager > Active Multicast task and if I boot the host it complains “Invalid Multicast session”
mysql> select * from multicastSessions
-> ;
Empty set (0.00 sec)mysql> select * from multicastSessionsAssoc

@rbaldwin is the multicast task actually being started? From what it sounds like no
-
I don’t think it is starting a multicast session. That the issue I’m attempting to resolve.
-
@rbaldwin WHat I mean, the log is refreshed showing a current timestamp?
-
yes, if I put a tail on the log file I see new entries for “* No tasks found!”
-
I uninstalled FOG as described here:
https://wiki.fogproject.org/wiki/?title=Uninstall_FOGReinstalled a Fresh install of:
Running Version 1.3.0-RC-16
SVN Revision: 5983Still not Multicast task is created when I create a multicast task and when the host boot they complain: “Invalid Multicast session”
I can multicast in troubleshooting with udp-sender/udp-receiver as described in the “Testing Multicast” section of https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_Downloading_-_Multicast
-
@rbaldwin Do the hosts in question have an image assigned to them?
-
@Tom-Elliott said in Invalid Multicast session:
@rbaldwin Do the hosts in question have an image assigned to them?
I can test this at home tonight.
-
yes, as I said earlier. I can image just fine if I use the deploy button. The issue is FOG isn’t starting udp-sender.
#grep udp-sender * -R
lib/fog/config.class.php: define(‘UDPSENDERPATH’, ‘/usr/local/sbin/udp-sender’);#ls -lah /usr/local/sbin/udp-sender
