Cluster GUI Problems [SOLVED]

[juliocbc]

Hello!

I were using a cluster with 2 nodes in the same subnet without any problems. Today I've joined a new node from another subnet to the cluster. The 3rd node showed up in the GUI and everything appeared to be OK.

Suddenly the Cluster in WebGUI stopped to work. in this mean time, our 3rd server, had a little disk issue and got the Proxmox reinstalled.

So, in WebGUI the 2 nodes became "Stand Alone" and the Cluster stop to work in WebGUI, even with access to both servers on it.

pvecm status output:

Where am I getting wrong?

So, in WebGUI the 2 nodes became "Stand Alone" and the Cluster stop to work in WebGUI, even with access to both servers on it.

How it stopped to work? Because the pvecm status and the screenshot show the to be expected things, one node is offline (the one which had disk issues, I'd guess) and the other twos are online and working, the output also shows:

So all is well from the cluster stack perspective, or do I miss something?

Hello!

In WebGUI Cluster Status, the Join information is not available anymore, the only enabled buttons are to Create Cluster and Join another cluster, both servers are stand alone.

The actions like migration or some another options that depends do specify the node, are unavailable too. (None node is available to pick in these options)

Appears to be the WebGUI is not “synced” with the cluster daemon or something like that.

Thanks!
