Solved Fog: multicasting across subnets
-
@K.Hays is the
FOGMulticastManagerrunning? Any logs about it in the log viewer? -
@Wayne-Workman yeah i watched it but i didnt check the storage node itseld to see if it actually saved there. I cant see why it wouldnt have though unless its a problem some people have. I think it was set up correctly. We were able to image to and from it.
-
@K.Hays and you watched the image replicate? And it’s physically present on the new node?

-
@Wayne-Workman yes,yes,and yes. We made sure of all that.
-
@K.Hays is the stoage node in it’s own group, and set as a master? Is the image associated with the new group?
-
@K.Hays it will do the same thing as before, and it just stops at the partclone screen.
-
@Wayne-Workman We got the node setup but multicast still doesnt work. We can unicast no problem.
-
@K.Hays During the storage node installation, you choose
sfor storage node. It will ask for the main server’s IP, and it will ask for the main server’s mysql credentials to use - you find those inside the FOG Settings -> Storage Nodes area. At the end, it gives you a username and password at the end that you use to setup a new node in the web interface’s storage management area. -
How do I set up this storage node? Sorry for the dumb question but we loaded fog as a storage node and we think we put it on the fog server correctly but apparently not.

@K.Hays said in Fog: multicasting across subnets:
Does the storage node just act like a segway from the server to the Vlan then?
No. The image data will exist on the storage node, and the storage node will send out the data via multicast.
However multicast is only possible from master nodes - so you will need to setup your nodes in a way that enables this - most likely each storage node/server being in it’s own storage group and being a master of that group, then you can share one image from the main server’s group to other groups.

@Tom-Elliott We’re about to test setting up a storage node right now. How exactly does this make multicast able? Does the storage node just act like a segway from the server to the Vlan then?
-
Personally I’d set up multiple storage nodes, on per vlan. Otherwise you have to enable udp broadcast forwarding. The reason I’d opt for multiple nodes is the multicast traffic should already be able to reach the subnet its on leaving less configuration needed on your network architecture.
