Multicasting
-
I’ve got something else weird going on now. I’m on SVN 3275 and when I try to multicast to a group, I see these errors in apache:
[Mon Apr 20 10:48:27 2015] [error] [client 10.162.3.26] PHP Warning: in_array() expects parameter 2 to be array, null given in /var/www/fog/lib/pages/TaskManagementPage.class.php on line 344, referer: [url]http://10.162.1.212/fog/management/index.php?node=tasks&sub=listgroups[/url]
[Mon Apr 20 10:48:27 2015] [error] [client 10.162.3.26] PHP Warning: Invalid argument supplied for foreach() in /var/www/fog/lib/fog/Host.class.php on line 978, referer: [url]http://10.162.1.212/fog/management/index.php?node=tasks&sub=listgroups[/url]
This is an issue that seems to be related just to my installation of fog and our database, as it works correctly on a fresh install of the SVN. I’m not sure what I should be asking now: Is there a way to check for invalid data, or what would be a good troubleshooting step? At this point I don’t think multicasting itself is the issue (again, because it works on a fresh install)
-
Maybe try to re-create that group? Remove the computers from it, delete the group, then re-create and re-add computers?
-
Hmm, we’re getting closer. I only get the second error now:
[Mon Apr 20 11:11:44 2015] [error] [client 10.162.3.26] PHP Warning: Invalid argument supplied for foreach() in /var/www/fog/lib/fog/Host.class.php on line 978, referer: [url]http://10.162.1.212/fog/management/index.php?node=group&sub=deploy&id=84&type=8[/url]
Edit: Sorry, still getting both errors. I had my log scrolled down too far to see the first ones.
-
I guess I’m not understanding what the issue is. Is it not working, or you’re just worried about the errors?
-
Ahh sorry, I wasn’t quite clear.
It is not working. When I click multicast for a group, I see the tasks for the individual machines show up under active tasks. But nothing appears under Active Multicast Tasks.
-
Then I’d recommend trying to truncate the multicastSessions and multicastSessionsAssoc tables. Also clean up any left over taskings:
[code]truncate table multicastSessions;
truncate table multicastSessionsAssoc;
delete from tasks where taskTypeID=‘8’;[/code] -
Ahh it was the leftover tasking that was holding me back. It’s working now and I’m currently watching 4 machines being multicasted to. Thanks again everyone.

If the default TTL is maybe 24 hours, then this guy wouldn’t have had the multicast issues the next day… it’d just resolve itself because the old tasks would get deleted.

I like this idea. Usually when I’m imaging, I start the task and go PXE boot the machine(s) within a few minutes - maybe an hour or 2 at most. Maybe there could be a custom TTL for users who would want a longer timeframe?

why not let the fog server wake them up with wake on lan?
-
Ha. I’d love to. Long explanation there though, totally unrelated to fog. We have teachers who use netop vision to wake up their computer labs in the morning. They complained about the extra time the pxe boot added to startup. I know, all of 15 seconds at most, but that’s a battle I wasn’t willing to fight. So 90% of our labs are set to boot right to the hard disk when they get the magic packet.

You can turn off the FOG menu… that’ll cut down on the time.

Hmm, that’s a possibility. I’ll keep that in mind for the summer when we go touch every station.

we have snapins that we can run to change the boot order for most of our dells

Can you elaborate on this? I’m interested in it.
I’ve yet to even use snapins, going to have to sit down and mess with it eventually.
