cluster changes - corosync

[Spiros Pap]

Hi all,

I tried to setup a cluster of 3 nodes and I run into problems. I want to setup two interfaces on each node for the cluster (primary/backup) and I tried to follow this:
https://pve.proxmox.com/wiki/Separate_Cluster_Network#Configure_corosync
* Note: the cluster right now is not in a working condition
I did a "pvecm expected 1" and I changed the config to this, to all the nodes (adapting the bindnetaddr IPs). All nodes say this:
=======================================

Corosync.conf:

}

totem {

}
interface {

}
ip_version: ipv4
secauth: on

}

Any ideas on what to do next?

Thanx,
Sp

PS: PVE version is the latest (5.1-3)

Hi,

is this configuration on all nodes the same?
can you resolve the node names from the ring_addr?
I personal like ip address more than names in the ring_address.

Hi Wolfgang,

Yes the config was the same and the IPs were resolvable via /etc/hosts.
I also tried to remove a node and readd it but this also didn't work.
Now, I have reinstalled proxmox and I will try again when I have my network config stabilized.

Anyway, It would be nice if someone could give instructions how to destruct a cluster and rebuild it again (the files involved etc).

Regards,
Sp
