@Joe-Gill I believe I found the issue why your nodes weren’t continually running the service. This was completely unrelated to multicast in and of itself. This should be fixed for RC-2.
For multicast tasks, I believe I’ve found an even keel for things. The location plugin moves hosts to the node to be used. However, if the node was not the “master” node in the past, the host wouldn’t have been looking to the location’s node for its tasking. (This is not specific to you @Joe-Gill rather more to @Hanz and others using location plugin). I’ve created a hook for the FOGMulticastManager service to enable Storage Node Specific locations to start multicast tasks.
All of this should be available fog RC-2 when it get’s published.
Thanks for reporting, and sorry it took so long to respond.
Remember @Joe-Gill, the logs you need to view should be those of the “master” nodes. That doesn’t mean you shouldn’t see anything, but I found earlier today (23-JUL-2016) that the “halt” is because the node is not a master. I’ve fixed it in the RC-2 and all appears to be working properly now.
