Main Screen 1 node but 4 are connected


(Dlink7) #1

I have 4 nodes in UCP but only 1 shows on the main screen. Do I need to something else?

Hi dlink7,

If I understand your problem correctly, the cluster controllers section on the main screen only shows HA replicas (add --replica when using the UCP tool “join” command). However the Nodes box should still show 4 in your deployment.

the main screen was stuck at 1, Is that only for the HA replica?

Can you put up a screenshot of the main page?

Are your hosts VMs? If so, did you clone the VMs? This could result in duplicate Docker Engine IDs which Swarm would read as the same exact host. Check out this post for details:

One more question: Are you running UCP 1.0 or an earlier version? I noticed your system is unlicensed, and UCP 1.0 does not allow joining of new nodes without a license…

Ok, sounds good. Be sure to follow the beta uninstall procedures either in the latest beta email or this post:

Otherwise, I’ve experienced my browser caching the web app and having to clear my cache before UCP gui changes were entirely effective.
