Multicast in FOG 1.3.3 Not Starting

Description

Hey Guys! Recently upgraded to FOG 1.3.3 (SVN Revision: 6061) and it seems that my multicast functionality has stopped. When I was using 1.3 RC it was working properly.

I start the session through the Image Management page on the Fog web interface. I am able to join and the session and get Partclone to load but that’s when things stop, I know its supposed to start after either the timeout or client count is reached but that doesn’t happen.

I can see the multicast session on the fog web interface and see that there are machines in it and it says the session is “In Progress”

I’m wondering if this is a known issue or if its just happening to me.

Any advice?

Is the FOG Multicast Manager service running?

systemctl status FOGMulticastManager -l should give us any errors being thrown.
Can you give us a view of the Logs? (From GUI goto FOG Configuration Page->Log Viewer->Select Multicast Manager from the dropdown on the left top of the window)

@PBrow Can you stop the service:

systemctl stop FOGMulticastManager

And attempt starting the service manually?

php -f /opt/fog/service/FOGMulticastManager/FOGMulticastManager

@PBrow Also, based on what I’m seeing it appears the extensions FOG requires are not availabled (probably because ubuntu separates php processes of “apache” based and “cli” based.

Attempting to hit you up in chat.

Remoted in. Issue possibly appeared from an Ubuntu update.

Essentially, however, the services were not able to start because PHP was missing the mysqli extension. I suspect it was removed (or at least unlinked) during one of these OS updates.

Cleaned up/fixed this by editing the /opt/fog/.fogsettings file and removing the php_ver, php_verAdds, and packages lines. Reran the installer and everything needed installed properly and the services all appear to be working properly too now.
