Cluster creation

[citlex]

Hello everyone,
I have one server with Proxmox 7.1.4 installed and another one with Proxmox 7.2 and I would like to create a cluster.
I know it is not the best to create a cluster with only two nodes but it is convenient for me.
Could there be any problems creating a cluster between different versions of Proxmox?

Hi,

Since they, both PVE servers are under version 7.X it should work without any issue. However, we recommend upgrading both servers to the latest version of Proxmox VE 7.3 [0]

Thank you for your response Moayad.
One last thing: how can you do the update via GUI? I read that it is possible but I didn't understand how.
If I do an update/upgrade the version always stays the same.
Thank you

Hi,

By going to PVE Web UI (Datacenter->{NodeName}->Updates) then Refresh and Upgrade.

I always do as you say but never get a version upgrade.
I point out that I do not have any enterprise subscription

If you don't have an enterprise subscription, you have to use the no-subscription repository by going to the Repositories tab and disabling the enterprise repository, and enabling no-subscription. Then you can do upgrade.

I saw that there is no-subscription repository but my server (the first one with Proxmox 7.1.4) is in production.
In your opinion is this repository safe or do I risk a mess happening?

It's recommended to use a subscription for the production server [0]. The packages in the non-subscription and enterprise repositories are the same, but they are first tested in the non-subscription repository before being made available in the enterprise repository.
