Can't add a Node in a Cluster

[Leonardo Ramirez]

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

root@pve3:~# pvecm add 172.16.100.101
Please enter superuser (root) password for '172.16.100.101':

Are you sure you want to continue connecting (yes/no)? yes

Login succeeded.

If I try to add it direct from the cluster side, it send me this message:

root@pve2:~# pvecm add 172.16.100.102
detected the following error(s):
* authentication key '/etc/corosync/authkey' already exists

* this host already contains virtual guests
* corosync is already running, is this node already in a cluster?!

You cannot mix pve5 with pve6 nodes in a clusters. I suggest you update your nodes first.

 

[macleod]

So, this scenario is not possible ?
- update all pve5 to corosync 3
- foreach server in pve5:
- move all vms/ctx to another machine
- remove server from cluster (after shutdown)
- install pve6 (format disks, make local storage modifications)
- join freshly installed pve6 server in cluster
(until all pve5 are now pve6)

Hi Dietmar,

Thanks for your answerd. I will update it, and I'll tell you how to gone.

Tks.
