hi
i need to configure a cluster on unicast Infrastructure (hetzner datacenter).
i use this:
----------------------------------------------------------------------------------------------
Start by creating the cluster on one of the nodes

pve1# pvecm create YOUR-CLUSTER-NAME

If you’re using unicast instead of multicast, I found it easier to edit the file /etc/pve/corosync.conf and add each cluster node, plus add transport: udpu inside the totem block. Once that was done I rebooted the server. When it came back online, set the expected vote count to 1 using the command

pve1# pvecm e 1

Then on each additional node, you need to add it to the cluster

pve2# pvecm add IP-ADDRESS-CLUSTER
----------------------------------------------------------------------------------------------------
but after doing this the corosync has stoped and client wasnt add to the cluster.
do anyone knows a way for doing this?
and another question, can you guide me about this part:

add each cluster node, plus add transport: udpu inside the totem block.

maybe im doing this in a wrong way!can you tell me with an example?
 
you should simply add
transport: udpu in totem block

(and increase config_version +1).

don't change expected vote # pvecm e 1, don't add other nodes manually in corosync.conf.

reboot (or restart corosync && pve-cluster services)

and then simply add

pve2# pvecm add IP-ADDRESS-CLUSTER
 
thanks for reply.
but i did this and and when i try pvecm add IP-ADDRESS-CLUSTER an error occurred and the second server didnt add to cluster.
do you have any Experience in using Vswitch in hetzner?

do you have the error message ?
is the /etc/hosts ok ? (with correct ip address of the management ip of the node)

Never used vswitch from hetzner, but unicast should work out of the box.
