Hello,

 

Trying to use Veeam to do ProxMox backups, I was able to add 1 host from the cluster, and deploy a worker to it, but when I go to add the second host, it tells me that its already added, but its not in the list and VMs from the other hosts are not showing up.

I tried via IP or DNS name and results are same, it says:

“Failed to register cluster. The Proxmox VE node 192.168.1.226 has already been added to the backup infrastructure”

but its not there, see below (the 192.168.1.225 is the first host in cluster and there are 2 more .226, .227.

 

What am I doing wrong here ?

 

The documentation said to add each host individually from the cluster:

 

Important

If you want to add a Proxmox VE cluster to the backup infrastructure, consider the following:

  • Each node of the cluster must be added to the backup infrastructure separately.
  • The name of the cluster must not be changed in the Proxmox VE administration portal after you add it to the backup infrastructure.

In general you're doing nothing wrong and have to add all hosts from the cluster. Is it possible that the hosts all have the same BIOS UUID?

They do in fact have same UUID, based on the output of dmidecode -t system. 

So I guess UUID is the issue ? I`m not able to change that in BIOS on this boxes. So I guess I`m out of luck using veeam ? There is no workaround ?

The hosts are identified by the UUID that's why you're seeing this issue. I don't know any workaround unfortunately but I would suggest to open a support case. Maybe there's a solution for this.

Im on community version, so I guess no support. Tried to figure out how to change in BIOS, but this boards dont support that or so it seems. I guess I`m out of luck, which is is sad. 

You can still open a case with community edition, but you will only get best effort support. Still worth a try anyways.

I will try, thanks. I thought Forums was the only support avenue for the CE
