Hi!
I have a problem with proxmox, I can't join the cluster, the message:

Are you sure you want to continue connecting (yes/no)? Login succeeded.
check cluster join API version
No cluster network links passed explicitly, fallback to local node IP ''
Request addition of this node
An error occurred on the cluster node: can't add existing node 'pve'
TASK ERROR: Cluster join aborted!
Click to expand...

When I change the hostname to another according to this instruction:
https://pve.proxmox.com/wiki/Renaming_a_PVE_node
/etc/hosts
/etc/hostname

Network or browser doesn't get up, I have to log in via monitor, restore the previous name and do a reboot
Any ideas?

Proxmox 8.0
 
Hi! What do you want to archieve? Please post?
  • /etc/pve/corosync.conf
  • /etc/hosts
  • /etc/hostname
No cluster network links passed explicitly, fallback to local node IP ''

This sounds like you did not define the link for the cluster-network? Could you try using the UI, it has the same features for the thing you want to archieve. Please also post the output of the files from above from all nodes that are part or will be part of a cluster. If you use cli, post the command you are using for cluster-join/cluster-create.
 
Hi
lets see if there is something in the journal why the renaming did not work. Can you give me the output of journalctl --since "2023-09-09" > $(hostname)-journal.txt
 
root@pve:~# journalctl --since "2023-09-11" > $(hostname)-journal.txt
root@pve:~# journalctl --since "2023-09-10" > $(hostname)-journal.txt
root@pve:~# journalctl --since "2023-09-09" > $(hostname)-journal.txt
root@pve:~# journalctl --since "2023-09-9" > $(hostname)-journal.txt

i try connect cluster to this:

1694447648012.png

From this:

1694447707145.png

both servers have promox in the same version, updated on the same day.

It looks like the wrong hostname (same in both).

After using proxmox wikipedia, the server does not get up (hostname change).

I want to make a cluster of two servers.

I actually mean the files that the output generates

On your example this host is still called pve. Have you rebooted after the rename?
 
After typing these commands, nothing happens - a empty log?

If I change the host data according to wikipedia and restart the server, proxmox does not get up. I only have a clean terminal available via iLO on the server (equivalent of idrac on dell). If I undo the changes to the files, reboot - then it gets up again. Really, I do not know what I am doing wrong. I'm doing it according to wikipedia, but this is an article from 2012 I think, then something may have changed by then.
 
can you show me the

no file has been created in the folder you executed this?

can you share the /etc/hostname and /etc/hosts file?

Glad to hear! If your problem is solved, please set this thread to "solved" so in the future people find the solution more easy :)
 
Yeah, it certainly isn't.. The rename didn't go through, to say certain one would need much more details, not just a short journalctl excerpt, and ideally know the full steps you've done. The name change could have either failed because some clustering was already half-configured or because some steps got simply left out.

Now that you formatted the node the logs are lost, so we cannot say for certain what the actual issue was, but if such things happen again (to you, or anybody else, reading this in the future) please also check the failed services:
systemctl --failed

Check for any leftovers of the old name, especially in /etc/hostname and /etc/hosts and /etc/corosync/corosync.conf (which jsterr request first but was never answered...)
