@amartinez Hello, I found this in this forum: “The storage nodes don’t have multicasting capabilities. So storage nodes are limited to unicast imaging.” It’s correct?

@amartinez Hello, one year later…: We have updated nodes (B,C) to fog version 1.5.9. Now, all is in version 1.5.9. But…we can’t do work multicast!!.
This is the server configuration:

This is the master log:

And this is the node log (where is the image):

Thanks for your help!!

@tom-elliott I’m sorry for the repetitions…
So, we need update nodes with 1.5.2 to 1.5.9.
Thanks for your help!!.

@tom-elliott
This is the multicast.log from Node where is the image:

And this is the multicast.log from Fog-server-Master:

when we send the multicast task.

With unicast works fine.

Thanks you!!

@tom-elliott
ok…but the multicast not start.
Node B IP: x.x.122.2
Node C IP: X.X.122.5
Master-Node IP: X.X.122.10
All in the same VLAN.
When we start unicast session all ok:

When we try multicast not start:

Thanks you for your patient!!!

@tom-elliott
I dont understand…Is all ok?

@tom-elliott

This is the output at the fog-server:

but the image is in the node not in the server:

I remember:
-We have a Fog Server: A

• And 2 nodes: B, C

The images are in nodes: B,C. Not at fog-server A

Thanks you in advance!!!

@tom-elliott Yes, the image path exist…and when we send under unicast this image all is ok. Dont works with multicast.
Thanks you!!

@sebastian-roth
This is the new log at the master node:

@sebastian-roth
