FOG Multicast Problems / Partclone fails to finish
-
Remoted in. The .22 was correct. The 17 was the “central server” but .22 is where the images are stored.
The issue(s):
- DB was being connected to via the user fog and it’s associated password, but the user was not given privileges on the fog database.
- The Main server (.17) had bind-address enabled.
Once I updated the DB to allow the ‘fog’ user to access the fog database AND disabled the bind-address, the node (.22) was able to startup the FOG Services (which was failing as it couldn’t contact the database). I watched the multicast log in particular after setting up a multicast task and saw 3 of the 4 clients in that tasking link into the Multicast side. (Still waiting to hear if partclone will work and if the 4th client worked properly).
I suspect this issue will be resolved, but please keep us posted.

Hi guys,
Tom, thanks again for all the help! Everything is happy. The multi-cast we setup finished just fine. I’m making a new image today and imaging another lab. I doubt they’ll be any more issues with multicasting.
I’ll re-post if more issues arise.
Thanks!!
Cheers,
Joe Gill

I spoke too soon!! I had a batch fail on me again…

I’ll be around until 5:30 MST this evening if you’d like to try and remote in. Thanks!!

@Joe-Gill Seeing s FOGMulticastManager doesn’t appear to be running, what happens if you restart the service?
service FOGMulticastManager stop; sleep 5; service FOGMulticastManager start -
lcarr@Fog:~$ ps ax | grep udp 3686 pts/3 S+ 0:00 grep --color=auto udp -
lcarr@Fog:~$ service FOGMulticastManager stop; sleep 5; service FOGMulticastManager start * Stopping FOG Computer Imaging Solution: FOGMulticastManager start-stop-daemon: warning: failed to kill 1362: No such processAnd hangs.
-
That’s what I suspected. It should be running now. If you wanna check?
-
Thanks for checking things out Tom!
Looks like stopping and starting the service on both the Server and Fog Storage Node solved the problem. The hosts are happy and the task is going!
Cheers,

My problem is back again. I tried shutting down and re-starting service but I’m hanging up again at the Particlone screen.
Ran this on both Storage Node and Server…
root@Fog:/# ps ax | grep udp 12432 pts/1 S+ 0:00 grep --color=auto udp root@Fog:/# service FOGMulticastManager stop; sleep 5; service FOGMulticastManager start * Stopping FOG Computer Imaging Solution: FOGMulticastManager [ OK ] * Starting FOG Computer Imaging Solution: FOGMulticastManager [ OK ]Also…
Tailed the Multicast Log File on Storage Node below…

Any thoughts here? -
Re-update and see if it is working?

Running Version: 8140
SVN Revision: 5698Is that current? I don’t see any options under …
Fog Configuration > Kernel Update >> Published Kernel
-
@Joe-Gill not even close. We’re not trying to update kernels. You need to update FOG as a whole.
-
So what’s the easiest method to update FOG?
-
-
Well I updated via SVN. Still have the issue. I’m also experiencing an issue reading the Dashboard disk usage. I can send you a screenshot of that if you’d like.
You cannot delete members of existing groups…
Also cannot add members to new groups…
Any help is greatly appreciated.
Thanks!

Post that to this thread:
https://forums.fogproject.org/topic/7875/storage-group-activity-inconsistenciesAlso, try to clear out multicast stuff in your DB with commands found in here:
https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_Downloading_-_Multicast -
How about adding members to a group? I can’t add any members to new or existing groups.
-
@Joe-Gill That would be another seperate problem in the current fog trunk that probably doesn’t directly impact the multicast process I’m trying to help you with. Please create a bug report about adding hosts to groups, provide your version and the exact click-for-click steps you’re doing - also include apache error logs from Web Interface -> FOG Config -> Log Viewer -> Apache error logs.
