[SOLVED] Cluster Issue

[aPollO]

Hi Guys,

i tried to add a second node to my cluster. I created the cluster on node proxmox01 and then added the node proxmox02. I got some errors cause my hostnames. I corrected the issue and now all is resovable and correctly added to the /etc/pve/corosync.conf.

I rebootet both nodes. But on the proxmox01 i only see this single node in the tree with an ? and on the second node proxmox02 i see both nodes but can't make any change. Both nodes shown with an red x.

Here ist the output if pvecm status

}

I found out that un the .members file the wrong ip address is used. I have on both nodes the subnets 192.168.10.0/24 and 192.168.30.0/24. and the hostnames proxmox01 and proxmox02 resolv to the first subnet, proxmox01.giga and proxmox02.giga resolves to the second one.
I want to use the Subnet 192.168.30.0/24. Have i something to change?

Spoiler: .members node 1

root@proxmox01 ~ # cat /etc/pve/.members
{

"proxmox02.giga": { "id": 2, "online": 1, "ip": "192.168.10.8"}
}
}

Spoiler: .members node 2

root@proxmox02 ~ # cat /etc/pve/.members
{
"nodename": "proxmox02",
"version": 6,
"cluster": { "name": "cluster01", "version": 2, "nodes": 2, "quorate": 1 },
"nodelist": {
"proxmox01.giga": { "id": 1, "online": 1, "ip": "192.168.10.30"},
"proxmox02.giga": { "id": 2, "online": 1}
}
}

i attached screenshots from both servers. I think somethink does not work correctly i dont know. How can i debug this a bit more?

Okay i think i finally got it. I changed corosync.conf one more time and correted the "names" back zu proxmox01 and proxmox02 without the .giga and then added a ring1 with the second ip adresses. now all works fine.
