Do you mean the master node of the ha-manager by "main node"? Because generally Proxmox VE clusters are multi-master clusters, where each node can do all management tasks.
Maybe the HA simulator would be intersting for you?
cross cluster features are on the roadmap, but there is no fixed release date yet.
Do you mean replication like in the existing storage replication in PVE or in a broader sense? In the latter case, backup & restore might be one way.
Some recommendations can be found in the Administration Guide:
Es gibt zusätzlich im GUI einen Dialog um einen Directory Storage zu erstellen: Node -> Disks -> Directory.
Falls da steht "no disk unused" muss die SD-Karte wahrscheinlich zuerst komplett gelöscht werden:
wipefs -a /dev/...
dd if=/dev/zero of=/dev/... bs=1M count=200
Da würde ich mir vorerst...
Does the boot log mention problems with any services?
But you said "I've Setup both with ZFS Raid 10"? Do you want to create an additional pool? What raid controller do you have exactly?
Do you have logs for the replication? Is there an error?
It might be easier to create backups, do a new installation with PVE 6 ISO and restore the backups as outlined in the upgrade guide https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0#New_installation
The journal entries look OK.
Please try ssh with multiple -v options, like
ssh -vv <destionation>
and also to get the Proxmox VE web interface via command line for an exact error
curl -k https://localhost:8006
It might not help for that specific problem. But generally upgrading to the latest version of Proxmox VE is recommended.
To avoid the GUI, you can use a tool like scp to upload your ISO image via command line interface. The path on your PVE host that corresponds to ISO images on your local...
Actually, I don't think that you're missing something.
This should be possible according to your screenshot.
Could you please execute the following command and copy&paste (using the code function of the forum, there is a button </>) the output of it?
