Need advise on the Join Cluster

[cocobanana]

HI,

I have confusion and questions here.

I have 5 Nodes that runs under production that already join cluster to Node-01 and IP is 10.0.0.1

- Node-01 - 10.0.0.1
- Node-02 - 10.0.0.2
- Node-03 - 10.0.0.3
- Node-05 - 10.0.0.5
- Node-06 - 10.0.0.6

Now I am in a midst, I have another server and the name is Node-04 and IP is 10.0.0.4 that join to a cluster, My questions and my situation is:-
1) Can I join Cluster by to Node-02 ( 10.0.0.2 ) or other Node and IP as above?
2) Node-01 ( 10.0.0.1 ) need to be replace to a server that is on the way to our office, can I use that new server and rename it as same Name and the same IP address as Node-01 ?
3) If I want to add a new server and join cluster ( example Node-07 - 10.0.0.7 and Node-08 - 10.0.0.8) by using other IP( as above ) that in a same cluster, is it possible?

Please assist.

Thanks

There is no dedicated master in Proxmox cluster - all nodes are equally capable to serve as end-point for new members to join.

2) Node-01 ( 10.0.0.1 ) need to be replace to a server that is on the way to our office, can I use that new server and rename it as same Name and the same IP address as Node-01 ?

You can - you should read this thread https://forum.proxmox.com/threads/how-to-replace-a-failed-node-in-a-two-node-ve-6-cluster.67917/
there are also many others on this topic. Make sure you read the entire thing before you do anything.

of course, you are just expanding cluster https://pve.proxmox.com/pve-docs/pve-admin-guide.html#pvecm_join_node_to_cluster
