@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:

Thanks you!!

@sebastian-roth
This is the multicast.log from the master node:
fog@fog:/opt/fog/log$ cat multicast.log

[07-05-21 8:11:49 am] | Unable to find image path

Thanks.

@sebastian-roth We had an old master node with version 1.5.2 and multicast works fine. We have updated this “old master node” to version 1.5.9. and dont works multicast, unicast works ok.
So, we need also update nodes B, C to version 1.5.9 (as the server)?.
Thanks you!!

Hello, we have in our school: 1 server A, with 2 nodes: B, C

The server A has fog 1.5.9, and the nodes have fog 1.5.2
Whe we try to send unicast from any node (B,C) this works fine.
But when we try to send multicast from any node this no start.
In /opt/fog/log/multicast.log at the server we have this message:
“Unable tu find image path”.

Thanks in advance.

Hi, we have a network with a Fog Server (main server) and 2 nodes (A,B), all at the same VLAN . When we try send a image stored in node A, the Fog Server search this image in both nodes A and B.
We would like some help on this problem.
