Node joined the cluster with wrong IP address

[elsha500]

Hello All,

We have an 18 node Proxmox cluster of version 5.4.
We have added a another node to the cluster, but we have added it using the wrong ip address on a different vlan than it is supposed to be.

The cluster network is on network: 10.0.0.0/24 and we have added the node with address 192.168.1.19. ( The two VLans can talk to each other but multicast not )

I can not remove the node right now because pvecm nodes does not show the node in the output. The only thing I can think of is to modify /etc/pve/corosync.conf and increase the configuration number. But this would require a full reboot of the cluster as far as I know.

Is there a way to remove this node or change it's ip address without rebooting all of the cluster?

Thank you in advance for your help.

Note:
I have corrected the ip address on the new node and changed both /etc/network/interfaces and /etc/hosts
I did not however change corosync.conf because I know that this is a clustered file and it will affect the rest of the cluster.
