Hi,
I purchased the book Mastering Proxmox and tried to follow the explanation.


I wanted to create 2 notes in a cluster.


I created 1 cluster.


Follwoing the information in the link:


https://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster


To add a node, I entered the command :


pvecm add 192.168.104.27


and received the error message :

authentication key already exists




How can I add a second node to my cluster?


Thanks
 
are you issuing that command from the joining (EMPTY, no VMs) node?
ie: 192.168.104.27 is NOT the address of that node but the address of the first node where you created the cluster, right?

Thanks for the help.

Actually,I purchased a dedicated server: 151.80. xxx.xxx

I don’t have any VM ‘s yet.

192.168.104.27 was just a randon local ip address I selected to create the second node.



There is the result of the command pvecm status if that can help:

root@dublin:~# pvecm status

And there is the result for:

cat /etc/hosts:



root@dublin:~# cat /etc/hosts


# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
151.80.xxx.xxx dublin.com dublin
# The following lines are desirable for IPv6 capable hosts

ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
 
Thanks,

I never works with linux distributions before.

This is for tests purposes.

What would be then the best practice to create 2 nodes on the same cluster?

I only have 1 ipv4 nad 1 ipv6 on my dedicated server

I can erase and reinstall proxmox if required.

Thanks
 
how many servers do you have?
you need at least 2 servers to have a cluster...

1 is in hosting? and has 1 ipv4 nad 1 ipv6 address

the other?

What exactly are you going to cluster if you only have one server?

This isn't a Linux thing, it's a server thing. You can't cluster any OS with a single server....the entire meaning behind cluster is to utilize more than one computer to perform a task....
