cluster

Hi, I'm new to proxmox cluster setup. I've setup a 3 nodes on a cluster with a dedicated network. Recently, one of our nodes crashed and unable to recover (basically it's dead). I want to remove the dead node from the cluster but I'm afraid that it might also broke my other 2 nodes. From the...

Hallo zusammen, bisher haben wir nur Docker Swarm verwendet, wollen nun zwecks erhöhter Sicherheit auch noch eine Ebene mit VMs einziehen, Proxmox sieht dafür sehr geeignet aus. Wir wollen 3+ Bare Metal Server bei Hetzner nutzen, VSwitch steht nicht zur Verfügung (mehrere Verträge), wir wollen...

Aloha, I have setup Proxmox 8.1.3 with an Ubuntu 22.04 mail server VM (zimbra) that has a static WAN Ip at site 1 I want to setup a replicated Mail server at Site 2 with a different static wan ip, So that if Mail server 1 goes down, Mail server 2 picks up and starts. Problem - The Static Ip is...

Hallo zusammen, ich migriere derzeit meinen ESXI zu Proxmox - mittlerweile habe ich einen temporären Proxmox 8.1 installiert und auch schon alle VMs von ESXI zu Proxmox migriert - mittels scp und vm importdisk. Alle VMs laufen nun auf dem temporären Proxmox Server und meinen alten ESXI habe...

Hi there. I have 3 nodes and I would like to set up a cluster, using a Dell M5024 SAN as a storage, accessibile via iSCSI. I know that this setup have drawbacks (no thin provisioning, no snapshots) but I already have the hardware, so I have to deal with it. Each server has: 8 10Gb ports 2...

Hello Proxmox Community, I hope this post finds you well. I'm currently facing an issue with my Proxmox setup, and I'm seeking advice on how to gracefully remove a node from a Proxmox cluster. Issue Summary: I accidentally created a Proxmox cluster with only one node, and now I'd like to...

I have a 6 node hyper-converged cluster where 3 nodes handle compute with SSD OSDs and other 3 nodes with HDD OSDs (they handle no compute). In the years since the first deployment a few patterns emerged: HDD pool is used exclusively for CephFS SSD pool is used exclusively for RDB (HA VM...

Hi, I just want to know how do you guys manage the networking for big proxmox clusters ? In my case I need to have multiple external networks for my VMs. For that, I create a dedicated vlan on my network switches and then configure a linux vlan interface on top of my linux bond and then add a...

Hi there, A quick question about Postfix configuration: how do you guys manage this effectively within your cluster? Do you have a dedicated container that does SMTP relay and "collect" emails from the rest of the cluster? Do you do it by node? What about CTs and VMs? I'm running a 9x nodes...

Hi! I am planning to do a new fun project! I want to try to create a Raspberry Pi cluster which I can host my own Virtual Machines on. And I got some recomendations to use proxmox as hypervisor. But I have some questions. 1. Do I need a sperate computer/device as the main hypervisor outside...

Hello, My company wants to set up a proxmox infrastructure but we're hesitating between two choices (we can adjust the hardware configuration of each server). We want to have at least 5Tb of usable storage. Depending on the choice, we invest in a backup server (PBS or TrueNAS replication) a...

Hi, we have a 3-node Proxmox VE 5.2-9 cluster (with CEPH) that is having issues with one of its nodes synchronizing. Connecting to its GUI, the node is online but all VMs are Offline, and starting them results in the message: "Cluster not ready - no quorum". pvecm status (node 1) Quorum...

Hi I am trying to create a shared storage (nfs) to a Truenas machine in a 2 machine VE 8.x cluster. I have direct 25Gb connections between the VE hosts and the Truenas host I have updated the hosts file on the proxmox hosts and confirmed I can ping CIRRUS (truenas) from both hosts...

What is the best Open Source solution to create a SAN for a 13 node proxmox cluster? I wouldn't want to use a product that after a year I find the license cost doubled or the company going bankrupt ;-) In the past I tried with Ceph.. but the snaps were much much slower than ZFS and over time...

Hi, I have three nodes in a cluster and when I try to VNC in the other two nodes's VMs, it doesn't work. Only the host node works. From my understanding, it's something to do with ssh? Can someone give a few pointers on how and what to set to have this working properly? Thanks

I am trying all day to mount an NFS share inside my proxmox cluster. These NFS shares already contains data from a previous cluster I ran. But for some reason it won't mount correctly. I run a proxmox cluster with 2 nodes and a synology nas as fileshare. Both my proxmox servers have 2 network...

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...

I would like to virtualise my OPNSense router, but I can’t get my head around how the network and my 3 node Proxmox cluster would deal with this. For example to setup a Proxmox cluster you need the machines to already have IP addresses and a working DNS. In my case the servers are also dropped...

I have older server with sata ssd(intel s3510) and Epyc 3rd gen server with intel p4510. I have a budget for another server(4th gen epyc with nvme ssd). I'm planning to build 3 node with ceph. If I mix those 3, would they bottle-necked by sata ssd server? I will run database intensive...

Hello. I have 5 separate nodes running now and I'm planning to create 1 cluster for all of them. However, they each have VM/CT IDs starting at "100". Will this present a problem, as far as ID conflicts, or will pvecm resolve these automagically? If I have to change IDs on the 4 nodes I wish to...
