I had a nicely working 2 node cluster (vmhost1 and vmhost2)

I installed a 3rd node (vmhost3) and used the join information to add the node, but the cluster is broken:

vmhost2 syslog:

On vmhost3, the folder /etc/pve/nodes is completely missing.

vmhost3 hosts file:

Code: 
127.0.0.1 localhost.localdomain localhost
192.168.45.12 vmhost3.internal.mihailand.com vmhost3

# The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

vmhost3 hostname file:

Code: 
vmhost3

The network is a flat network on 192.168.45.0/24, as can be seen from the corosync.conf above.

The networks connections worked perfectly fine prior to this. As I mentioned I was able to log into vmhost3's GUI to join the cluster. SSH still works, so I don't know how it could be a network problem.

I have a dumb switch connecting all 3 nodes.

I can ping from each host to each other host.

All nodes are very close in versions:

vmhost3 network interface:

Code: 
auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
    address 192.168.45.12/24
    gateway 192.168.45.1
    bridge-ports eno1
    bridge-stp off
    bridge-fd 0

I tried to update vmhost1 but it's getting timeout when processing triggers for pve-manager, so I think I kind of messed up there:

Code: 
Processing triggers for pve-manager (7.2-4) ...
got timeout

Restarting vmhost3 did not help.

Is there a way to salvage this cluster? I would prefer not to have to re-create it.

Okay I was able to remove vmhost3 from the cluster using the following instructions:

Code: 
systemctl stop pve-cluster corosync
pmxcfs -l
rm /etc/corosync/*
rm /etc/pve/corosync.conf
killall pmxcfs
systemctl start pve-cluster

The original cluster is now working again... I will try and remove all traces of vmhost3 from the original cluster so that I can try to re-add it hopefully.
 
SOLVED: I did not choose the Cluster network when joining the cluster.

Probably should not allow one to continue to join the cluster without making the choice, but it's my fault.
