Delete node - Node IP still in corosync.conf in totem section?

[dusty128]

Hi,
I have a little Proxmox 7.4 cluster I set up some time ago. Now my fist node died and I deleted it from the cluster. I plan to freshly install the node and add it to the cluster, but with the same name / IP address.

For that reason I checked every file in the /etc directory if there are any remains of the old hostname / ip address.

Interestingly, I still find the old IP address in corosync.conf (both in /etc/pve and /etc/corosync). The node is gone, but it is still in the totem section:

totem {
cluster_name: my_cluster
config_version: 11
interface {
bindnetaddr: 192.168.0.21
ringnumber: 0
}
ip_version: ipv4
secauth: on
version: 2
}

"192.168.0.21" is the IP address of the deleted node and is therefore unreachable.

Does anyone know why this (inexisten) IP address ist still in corosync.conf? Should I alter this IP address to some other Node IP?

Is there anything else to think about when I add the new node with the old hostname / IP Address? Maybe there are some other remains in /var/lib/pve-cluster/ I should be aware of?

Best Regards,
Hermann

What's the full /etc/pve/corosync.conf ?
Normally first remove any (lxc+vm) ha configs, then remove old node there, restart corosync (rewrites /etc/corosync/corosync.conf), then reconfig ha settings. Later reinstall your old pve node and rejoin it.
