Multi-Task Problem

Fernando Gietz

And the log of the multicast tasks?
/opt/fog/log/multicast.log.udpcastxxxx
Where xxxx is the ID of the multicast tasks.

Joe Gill

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!

Well 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!

Nothing is showing up in the logs at all.

And from the web interface…

And in the database appears?
See the multicastSessions and MulticastSessionAssoc

If you go to the Active Tasks page, the multicast tasks appears?

@Joe-Gill First make sure the multicast service is actually running: systemctl status FOGMulticastManager

You 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?

Joe Gill

@Fernando-Gietz

Which files would you like me to pull for you?

Fernando Gietz

/var/log/httpd/ssl_error_log
/var/log/httpd/error_log

Try to see if when tou create a multicast tasks appears any error.

Joe Gill

@Fernando-Gietz

Will do. I’ll tail those files and see what happens when I create a new task. I’ll report back! Thanks!

Joe Gill

@Fernando-Gietz

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.

Sebastian Roth

@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.

Joe Gill

@Sebastian-Roth

Awesome! That gives me a place to start. Thanks! I’ll do some digging. I’ll be tied up here in a couple hours for the rest of the day. I’ll post what I find out before I head out though. Thanks again!

Here’s an error!

Any ideas? I’ll be around all day today if you guys want to take a look at it.

Thanks!

Fernando Gietz

Hi @Joe-Gill
And the msAnon3 column, does exist in the database?

#desc multicastSessions;

Sebastian Roth

@Joe-Gill Sounds like your DB has more issues that what we have fixed last time. But this one sounds really strange! Please run DESC multicastSessions in the mysql command line and post output here.
