@zacadams so the session is starting. The clients can’t seem to get the traffic from the server. Are the client machines on a separate network from the fog server?

[zacadams]

@tom-elliott in this particular scenario the host is trying to communicate with the “remote” fog storage node, which is now a master node in it’s own storage group, and is on the same network as the host.

[zacadams]

I was able to resolve the issue:

One of the problems was that the multicast interface was set to the interface of the main fog sever (a vm running on ens192 interface) to the interface of what my storage nodes would be (physical machines on eno1 interfaces).

The other issue was the MySQL table on the main fog server being not accessible by remote storage nodes.
I could image from the remote storage nodes but the nodes themselves always had shown “A valid database connection could not be made” on the dashboard. The fix for this could be found here under the “Enable remote mysql access” section, granting remote users all privileges.

@zacadams what user where you using to talk with the dB? You should’ve been using fogstorage which is setup for you during installation.

[zacadams]

@tom-elliott That is the one I have been using, the passwords were correct on the fog storage node as well.

@zacadams Glad you got this figured out.
