Node goes RED

[soporte]

Currently I have a cluster of two nodes. the Master has the IP address 172.17.1.2 and the slave has the address 172.17.1.3. By accessing via web the master, the slave appears red. There is nothing in the logs, I can make backups of virtual machines, but I can not access status.

this is pvecm status:

root@proxmox:/etc/pve# pvecm statusVersion: 6.2.0
Config Version: 4
Cluster Name: pmxcluster
Cluster Id: 48436
Cluster Member: Yes
Cluster Generation: 524
Membership state: Cluster-Member
Nodes: 2
Expected votes: 2
Total votes: 2
Node votes: 1
Quorum: 2  
Active subsystems: 5
Flags: 
Ports Bound: 0  
Node name: proxmox
Node ID: 1
Multicast addresses: 239.192.189.241 
Node addresses: 172.17.1.2

and this is /etc/pve/.members:

root@proxmox:/etc/pve# cat .members
{
"nodename": "proxmox",
"version": 3,
"cluster": { "name": "pmxcluster", "version": 4, "nodes": 2, "quorate": 1 },
"nodelist": {
  "proxmox": { "id": 1, "online": 1, "ip": "172.17.1.2"},
  "proxmox-slave": { "id": 2, "online": 0}
  }
}

any help?

Thanxs

edit: this was working quite well for over a year.

Hi,
there aren't a master and slave anymore in pve2/3! And a two node cluster is not optimal because of quorum - use three nodes to get less trouble.

Does it help, if you restart the pvedaemon on the "red-node"?
Or restart pve-cluster?

Did you by any chance recently do an apt-get upgrade on the machines in this cluster?

no, both nodes were restarted and still does the same.

I add more info, if I login in the second node (the "slave") I see exactly the opposite, the node that i logged in is green and the other one is in red. It seems to be a communication problem in the cluster ... any ideas?

hi, do you have test to readd the node?

no, I did not want to get to that level, but if I have no choice I will begin to read to learn how to do ...

I recommend to readd the node, its the fastest way to have a solution.
you must delete the node and than remove the files and folders with the name of the node, after you add the node again and show, if it works.
