PVE6 cluster creation procedure

[dendi]

I'm just trying PVE6 (just updated from pvetest) on three test vps
I added a network with private address for corosync
created the cluster on the private address in the first node
joining the second node using private address I got time outs but the node is in the cluster
same for the third node
the private address is not in the etc/hosts file, is this required?
Anyway it seem to work!

Sorry for writing again, the cluster is working but someone can confirm that there is no need to add the ring address in the /etc/hosts files with PVE6?

No normally not. We now try to resolve a hostname and thus the address should already be in corosync.conf, you could check yourself:

cat /etc/pve/corosync.conf

joining the second node using private address I got time outs but the node is in the cluster

If you did this over the Web GUI it is normally to see timeout's after a bit for, the reason for this is that the node which joins the cluster needs to regenerate it's node TLS certificate, so that it comes from the same cluster root CA the other existing cluster nodes use (and thus they all can trust each other).

Thank you! I see this:

  node {
    name: p6t1
    nodeid: 1
    quorum_votes: 1
    ring0_addr: 10.7.96.3
  }

If I ping p6t1 it resolves the public IP, not the private 10.7.96.3, correct?

It's fine but for not skilled user I think it's better to show a warning message before joining a cluster... I missed it?
