cluster configuration

I'm currently managing a Proxmox cluster with three nodes configured for high availability (HA). I've observed some behaviors regarding LXC container management and failover mechanisms, and I'd appreciate any insights or clarifications you might offer. Preventing Duplicate LXC Instances: In our...

Hi there. I have a PX cluster built on 4 nodes, they have pretty much the same hardware spec which is 2xCPU sockets, 256GB of RAM and 3 network cards: 1x 2-ports 40Gb 1x 2-ports 10Gb 1x 4-ports 1Gb 1x 2,4TB SSD hardware RAID5 1x 2TB NVMe m.2 Because some configs are difficult to change and I...

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

I have 3 hosts (HP EliteDesk Mini i7-9700 each has 2 x nVME slots or can have 1 x nVME and 1 x SSD) which I have placed in Cluster. These machines were Windows 11 previously and I had to change some bios settings to boot and cancel some windows specific security. The attached image shows the...

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...

Hi guys. i have recently switched to proxmox after years of working with vmware products... so when it comes specifically to proxmox - i'm a noob. i have a 2 node cluster in my home lab. the "primary" node has been failing a lot and i am going to replace it how should i approach this? to first...

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...

Hello, I do have 3 identical Hetzner servers that I configured with their Installimage script - Hetzner-Installimage - and configured Network Bridged setup accordingly to their documentation - Hetzner-Proxmox-Network - configuration of network is similar on each host. Hosts are fresh, no VMs...

Hello, I am working on setting up a cluster with where the VMs are on local storage but use/sync to the shared storage for HA and Cluster options. The hardware I have is as follows: 3 proxmox clustered machines (will be more but 3 for now) - Each has local nvme storage Each has access to a SAN...

Hi, As some of you have already noticed in other threads, I have huge problems with the cluster and more precisely with adding a node and qdevice for quorum. Without writing too much, I'll describe my issues. I migrated from VMware to Proxmox, and that part was successful. I have two separate...

Hi there, I am try to add a second node (pve2) to a already existing cluster to replicate the container using zfs features. The actual problem is to setup the zfs correctly to the cluster without loosing all data from pce1. Here is what I have done: I had an Proxmox VE 8 Node using all my...

Hi, A possible stupid question but I would ask anyway... I have one proxmox node running Tesla P40 GPU. I recently bought a Tiny PC that I am planning to run Proxmox on and join as a cluster. Can I pass Node 1's GPU to any VM's that I build on Node 2 (Mini PC)? I do have Nvidia's Grid license...

I'm not very used to Proxmox... But meeting the demands of my customers stating to undestanding it a bit. And I'm facing a problem that is almost like a chiken or egg matter. I will mention a hypothetical scenario here, but this is one that is very close to what I'm frequently seen on...

Physical Hardware: 3 nodes with same Hardware 1 -1GB nic 2 - 2.5GB nic 1 - 10GB nic Network hardware: 1 - 8 port 10GBe switch 1 - 24 port 1GBe switch 1 - 8 port 1GBe Switch All LACP LAG capable I am trying to figure out what would be the best configuration for a clustered, HA, and CEPH...

Hello as the title states, I would like some insight on configuring my very vanilla proxmox cluster that is presently on my main network. Of Course, after the cluster creation I read (I know, I know, next time read 1st) that the cluster should be on its own network with intentions to configure...
