Multi-Task Problem
-
FOG Version – 1.5.6.3
FOG Server OS – Debian 9.9Hi all,
I ran into a problem Multi-Casting machines. I get the following message on my HOST.
Here is /opt/fog/log/multicast.log

It appears that FOG doesn’t recognize that an event has started. I have tried killing all multitask sessions, killing the multicast session PID, stopping and restarting multicast, restarting the server, running an update on the FOG server, clearing any flags in the SQL database, nothing has worked.
Any help is greatly appreciated!
Thanks!
Cheers,
Joe

@Sebastian-Roth Any ideas here?
-
@Joe-Gill Do you actually see the multicast task in the web UI? How do you schedule the multicast task? Please tell us the exact steps you do scheduling the task so we might be able to understand and reproduce your issue.
-
Yes. It shows up there like normal. Just nothing in the log.
-
And the log of the multicast tasks?
/opt/fog/log/multicast.log.udpcastxxxx
Where xxxx is the ID of the multicast tasks. -
What shows up in the UDP log is from over a year ago when I messed with multi-cast last. I am working on building a new server.
Thanks!

@Fernando-Gietz
@Sebastian-RothWell the problem persists on the new server… Multicast.log shows no new tasks and zero multicast.log.udpcstxxxx files in the /opt/fog/log directory. I’m betting the database issues persist on. I’ll be in first thing tomorrow morning. (7AM MST)
Cheers!

And from the web interface…

And in the database appears?
See the multicastSessions and MulticastSessionAssocIf you go to the Active Tasks page, the multicast tasks appears?
-
MariaDB [fog]> SELECT * FROM multicastSessions; Empty set (0.00 sec) MariaDB [fog]> SELECT * FROM multicastAssoc; ERROR 1146 (42S02): Table 'fog.multicastAssoc' doesn't exist MariaDB [fog]> -

@Joe-Gill First make sure the multicast service is actually running:
systemctl status FOGMulticastManagerYou are on the right track here. Try this:
SELECT * FROM multicastSessionsAssoc; -

The problem is that the multicastSession is not created ( I am very clever boy XD) but we dont know the reason of this behaviour.
Any errors in the php log?
-
Which files would you like me to pull for you?
-
- /var/log/httpd/ssl_error_log
- /var/log/httpd/error_log
Try to see if when tou create a multicast tasks appears any error.
-
Will do. I’ll tail those files and see what happens when I create a new task. I’ll report back! Thanks!
-
OK. So now it’s saying:
“Invalid MultiCast Session” on the hosts. Nothing new in the log. I have the /etc/httpd/logs/error_log pulled tail -f and nothing new is showing up there.
-
@Joe-Gill Unfortunately don’t have enough time to do another debug session with you. But maybe I can give you enough hints so you can dig it up yourself.
Remember that I enabled mysql query logging yesterday?! First you login to the web UI, clear all the old tasks there and select the group you want to schedule a multicast task for. Prepare this as far as possible but don’t hit the button to create it yet but enable database query logging (and clear the log we created yesterday):
shell> echo -n "" >/var/log/mariadb/query.log shell> mysql -u root -p Password: ... mysql> SET GLOBAL general_log_file='/var/log/mariadb/query.log'; ... mysql> SET GLOBAL general_log=1;Now click create multicast task and then stop query logging again:
mysql> SET GLOBAL general_log=0;Now take a look at the query.log file. What you are looking for is probably something like
INSERT INTO multicastSessions .... Just use search function of the text editor to find that part. Now when you find this you just copy the whole SQL command and try to execute that in the mysql shell manually. Most probably you’ll get an error from that and we might find out why.
