Hello Community,

I have followed this video tutorial (http://www.youtube.com/watch?v=tTy9axM1jT0) to create a proxmox cluster.
My question is: Is it necessary that both proxmox-machines contain the same virtual machines? My first proxmox machine
contains two ubuntu servers and the second one contains nothing and was just added to the created cluster at the first proxmox machine.

Hope, you can help.

Btw: Is there another instruction for creating a proxmox cluster for 2 nodes?

no,
join only empty nodes to (empty or not) existing cluster (even to first cluster node)

see this post, there's a link to the wiki article

Hi Louis,
no! VMs/CTs are only on one node at the same time. Without shared storage the data is also on one node - for migration pve copy the whole content to the other node (offline).

The config of the VMs/CTs are on the cluster-filesystem (below /etc/pve) which is the same on all nodes.

There are a lot of threads about 2-node-cluster (but with three you will have less trouble ;-) )

Hi guys,

thank you for your fast responds, so I guess I did it right. But if i do a "ping" on one ubuntu server and I disconnect the first node, I never get a reply from this VM. Do I have to copy the VM's from the first node to the second node after joining the empty second node?

(I've read the article from m.ardito's link but how can i get it work that my vm's which were on node1 before, are working)
