I have a cluster running, and I am trying to add a new node but receive the following error

root@vhost05:/etc/pve# pvecm add vhost13
detected the following error(s):
* authentication key '/etc/corosync/authkey' already exists
* cluster config '/etc/pve/corosync.conf' already exists
* this host already contains virtual guests
* corosync is already running, is this node already in a cluster?!
root@vhost05:/etc/pve#
​
So then I tried pvecm add vhost13 -force and got the following:

root@vhost05:/etc/pve# pvecm add vhost13 -force
invalid corosync config - unable to read version
unable to add node: command failed (ssh vhost13 -o BatchMode=yes pvecm addnode vhost05 --force 1)
root@vhost05:/etc/pve#
​
vhost13, which is the new server I am trying to add to the cluster is a fresh install of proxmox, which has been updated. It does NOT have any guests running on it. I presume at some point there has been a vhost13 in the cluster, but I would like to keep that hostname to keep naming consistent with rack location.
 
Hello all. I have this same problem, I triyed to add in both server but I keep the same problem.

this most likely means that the node is already in a cluster, and thus you can't join it to another cluster. To set up a cluster, you create it on one node and have other nodes join it. See also: https://pve.proxmox.com/pve-docs/chapter-pvecm.html

Thank you Fiona, but I deleted the old cluster in that server and removed the old keys, removed old vm but I still having the same problem.

root@vs1:~# pvecm add 10.4.12.99

Check if node may join a cluster failed!
 
The error says that /etc/corosync/authkey exists on the node 10.4.12.99. Are you sure you cleaned up everything from the old cluster? The supported way is to re-install the node before joining to a new cluster.

Thank you I just cleaned at the master server and it's working.
