I have a Proxmox V8 cluster with two nodes. I built the cluster 6 month ago. I am planning to add one more node to my cluster. Can I download the latest installation USB key and install the new node or there is a version compatibility requirement between a PVE cluster nodes? Thank you

Hallo zusammen, ich habe ein Cluster konfiguriert, wo nicht alle Nodes die gleiche Anzahl an Votes haben soll. Grund dafür ist deren Standort. Soweit so gut. Allerdings werden nach aktueller Konfiguration 17 Votes benötigt um Quorum zu erreichen. Aufgrund der Konstellation reichen allerdings...

I currently have two proxmox hosts running in a cluster for my homelab. I am concerned about what will happen if one of the hosts goes offline. Whether due to temporary reboot or possible hardware failure. What is the best way to ensure that the remaining host works properly if one of the nodes...

Hi everyone, I have an NFSv4 share setup on Synology I'm trying to add to 2 nodes Proxmox v8 (pve1 & pve2). I've used the Proxmox Cluster admin UI to add the share. pve1 connects no problem, however pve2 times out. Detailed setup info can be reviewed here ->...

I am putting together a 3x node cluster for my own education (before doing this for real at work!) and I have the following plan for subnets for the cluster. This setup is based on all the tutorials I've been able to find online, but I wanted to make sure I'm doing this right. I have enough...

Hi Everyone, I've had cluster of 3 nodes and I recently added a 4th that is on a separate subnet. Unfortunately, I forgot a firewall rule for corosync and RPCBind so joining node4 to the cluster has only partially completed it seems. I have subsequently fixed the firewall issue and made sure...

Outline: I'm wondering if there's any detailed documentation anywhere about exactly how the various SSH key files are used within a Proxmox cluster? In particular, what is the relationship between /root/.ssh/known_hosts, /etc/ssh/ssh_known_hosts, and /etc/pve/priv/known_hosts, and if replacing...

Hey Community, I have been working with Proxmox for some time now and want to make the next step towards Cluster. We are hosting our 3 Server at Hetzner. Every Server has it own dedicated IP from different Subnets. The ones Hetzner gives you when you order a server. I also understand that I...
