[SOLVED] 2 Server Cluster /HA

[Dafoxx]

Hey all,
Im trying to set up a 2 server cluster with HA as well
I have 3 servers, PVE1, PVE2 , and TureNas Scale running an NFS VM Store
24 Port Swtich to manage the nodes
When i now Add the 2nd node to the network it instantly takes out the cluster?
I've tryed useing an onboard NIC when you join another node for some reason it instantly goes offline and im baffled why
172.25.0.50 - PVE02 NiC1
172.25.0.51 - PVE01 Cluster Master
172.25.0.52 PVE1-Sync NiC4
172.25.0.53 PVE2-Sync NiC4

Establishing API connection with host '172.25.0.51'
TASK ERROR: 500 Can't connect to 172.25.0.51:8006 (Connection timed out)
Am unable to ping the node during the join process
Any help would be useful.

Regards
Dafoxx

Resolved the issue, the Switch configuration was set to an incorrect Vlan.

Please keep in mind:

For two nodes to run in a stable setup you need a third node nevertheless. There are acceptable workarounds if you have only two "real" servers: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_corosync_external_vote_support

Again: this is for the cluster in itself, not only for "HA". Without Quorum and one node failing you can not administrate the remaining node without additional "tricks" like "pvecm expected x"...

Good luck
