Adding external node to existing local cluster

[Rick L]

Sorry if this is repeated, I searched until I had to sign up and harass everyone.

I have an existing local cluster of two nodes , I would like to add an external, or colo node to the local cluster.
I assume this can be done in several ways but this should be done the correct way.

How is this accomplished - links or advice would all be appreciated.

Thanks, Rick

what "external" and "colo" means? A bit more detail please...

I have a local cluster ( local as in residential home office dynamic IP from ISP )
I also have a colocation server, or a racked server sitting in a datacenter with a fresh install of proxmox 3.1

With of course a static IP on the colocation server.

Since of course adding nodes to exiting clusters must be done from the [new] node, I am thinking either a VPN or ssh tunnel to reach the [local] cluster. Which is not public facing and has no direct or obvious means of connection from outside the local firewall appliance.

well would it work, open the vpn from home to remote, and then ssh into remote node, then add it to cluster?
but if the nodes local/remote are not permanently connected, the cluster will be always somewhat broken...? what's the purpose?
otherwise you could try dynamic dns solutions for home?

That is what I wanted to avoid - natting to the node itself publicly.

Purpose is to manage all nodes from one location, sorry if that sounded too obvious, maybe this is not what you meant ?
Since i am not sure 'exactly' how the nodes speak to one another, RPC ? I cannot be sure to come up with the best solution , to insure connection continuity as well as security.
