creating cluster and adding node to anexisting proxmox server

[Monteiro]

hi

we have a working proxmox server with vms in production.

Is it possible to create the cluster and add other node while we have vms in production on the fisrt node with no issues ?

the reason i am asking this is the following information on the wiki

https://pve.proxmox.com/wiki/Proxmox_VE_4.x_Cluster

Adding nodes to the Cluster
Login via ssh to the other Proxmox VE nodes. Please note, the nodes cannot hold any VM. (If yes you will get conflicts with identical VMID´s - to workaround, use vzdump to backup and to restore to a different VMID after the cluster configuration).

thanks in advance.

the joining node should be freshly installed or empty - the existing cluster nodes can of course have VMs, containers, ...

hi Fabian,

thanks for your confirmation

 

[orosmannaro]

the joining node should be freshly installed or empty

Even if there aren't VMID´s conflicts between the two hosts?


(the host that I want to set as primary it's an empty host. I would like to build the cluster and then migrate some VM)


Thanks

It would be nice if one could add a node to a cluster even if it contains vms/containers, as long as they are not in conflict.
