adding new proxmox server, move VM's/Create cluster?

[kitkat]

Hi,

not sure how to tackle this.

I just finished building a new 7.1 node install on a Dell R620.
I have a smaller 7.1 node with a few VM's on local storage.

I would like to create a cluster so I can easily move vm's from one node to another. Is creating a cluster the proper way of doing this? If so, do i create the cluster on the new Dell (more powerfull server) then add the second node? What will happen to the VM's on the node 2? the new node has no VM's and neither share the same storage, they both have their own.

Would like some directions on how to accomplish this please.

Thanks

Yes creating a cluster will allow you to migrate VMs between nodes in a cluster. Note that, if you use local storage, the migration will take a long time depending on your network bandwith and VM size.

If so, do i create the cluster on the new Dell (more powerfull server) then add the second node?

Note that you cannot join a cluster from a node that contains VMs. Thus, you would need to join the new node to node 2.

What will happen to the VM's on the node 2?

Since you do not have a cluster yet, the VMs on node 2 should remain. Unless you set up HA or migrate VMs manually.

You can read more about setting up a cluster in the manual [1]. Also note that it is recommended to have at least three nodes in a cluster, if you do not have a third node, you can set up a QDevice [2].

i ended up backing up the vm/s on NODE2 and restoring them on NODE1. Looks like it worked. now I'm gonna add NODE2 to the cluster.

Question now is about the local storage. I would like to use the NODE1 local storage on node 1 for ISO and backup since the drive on NODE1 is larger. How can I share the NODE1 local storage to NODE2?

You should configure some kind of shared storage on NODE1. You can use NFS or iSCSI to do that. AFAIK you cannot just share your LVM storage. You can take a look at the manual to see which storage types support sharing [1].

is there a howto on how to do this?
