cluster configuration

Hi, Ive been evaluating Proxmox and XCP for a while now and are leaning towards PM for a project. I only have 2 nodes at the moment with local storage (mix of SAS & SATA SSD). Can I get clarification on following. - 2 node clusters are a bad idea due to quorum issues, but you can run a QDevice...

Hello, For various reasons, one may want to change the SSH port. No security debate: it may be enforced by company policies and there's no reason to fight it from my perspective. The cluster manager documentation mention the port 22 is expected for ssh, but how does it connect to the host? Is...

I'm facing a bit of a challenge with my current project and I'm hoping that someone here might have some wisdom to share. For context, my end goal is to have a self-hosted S3 service replicated across 3 data centers (1 West coast, 2 East coast). I have 6 storage servers (2 for each DC) that are...

I have a rather strange question, and a nice use case. Cluster of 3 nodes on PVE 6.4-13, being moved offsite but not together. CONTEXT: Because of reasons, they cannot move all three nodes at once, so instead they will move first only one (A), then the other two(B&C). Adding on top of this...

I have read through the documentation and I'm not sure I'm following it well because I'm not even sure if what I want to accomplish is possible with Proxmox or not so I thought I'd ask here. I have a Proxmox node setup and hosting several containers and VMs. This started as a hobby and chance...

Hi There!, I have two PVE nodes (P1 and P2), When I'm logged in on P1 node, and try to access a VM on P2 node with virt-viewer I get "Unable to connect to the graphic server C:\Users\user\Downloads\9_NoK9Fd.vv" error message, Nodes are on different networks, but they have a 10G Ethernet...

I am looking at 2-node and 3-node ha/cluster configuration, testing out different dr scenarios. When I purposely disconnect the master node, seems the cluster wont survive. Any tips how to overcome this?

Hi All, Trying to get a basic cluster setup working between 2 nodes... third will be added later. All the servers are connected to 10.250.10.0/24 network. The nodes joined the cluster without any issues. Am able to ping the nodes and the nodes able to ping each other with a constant RTT of...

Hello Everyone, So I have two PVE nodes I edited the hosts file on both machines so they look something like this: IP1 stage-ve-01 IP2 stage-ve-testing then I went to PVE1 and created my cluster then copied its information, after that I went to PVE2 to join it to the cluster. After...

I'm creating a system for work to automatically deploy servers with proxmox to then be provisioned and then later decommissioned. The entire point of this system is that I don't pay for server time I don't use, so a lot of my work is creating code to automatically deploy servers on demand. I now...

Hi all; I've run into an issue trying to add a new cluster node. The new cluster node, when added to the cluster, fails to populate /etc/pve correctly with the necessary information and ends up with pve-ssl.key errors (file not found, etc), and does not join the cluster successfully. The new...

Hi all, As I understands it, for a cluster to be accessible from the GUI, we need half of the servers running +1 I have a cluster of 10 servers and I find it pretty annoying to be forced to keep 6 servers On all the time. Is there a way to get only 3? Under low month workload I could keep...

From the documentation, it seems to suggest that using a separate network interface for the cluster is optional, but when I try to create a cluster, there are no available interfaces to use. The current deployment only has one interface which is slaved by the linux bridge. I can add another NIC...

Hello all. I wanted to cluster my 2 nodes. I accidentally clicked 'join cluster' on both nodes... Now, on both nodes I have only one possibility and that's : 'Join information'. Is there a possibility to undo this? My Proxmox versions are 7.1.8 and 7.1.12 Hope anyone can help me. Thanks!

Hello, So ive run into a bit of an issue. I am going to join nodes to a cluster but for some reason 2 nodes didnt join. They just show up with red x's in the summary and I cant sign into their web interfaces after refreshing the page. For the 2 nodes Im seeing errors for the pve-cluster.service...

Hi, I have installed proxmox on an OVH cloud, following a restart of the cluster I can no longer reach the VMs of one of my subnets. In practice I have a vm that has the wan in the subnet 192.168.3.x / 24 and from the cluster it is not reachable. below I am attaching the configurations set on...

Hey Everyone, I am slowly reaching the end of my Ceph Cluster project and the absolute last thing I need to accomplish is setting up my PVE so that I can create VM's for the different VLAN's in my existing environment. So far I can confirm I can create VM's and have them migrate successfully...

Hello! I accidentally created a cluster with the wrong IP. There are currently active and important virtual machines in the cluster. How can I delete or modify a cluster without deleting the virtual machines? Then I'll create it again. Thank you very much!

Hi everyone! Does someone use servers with ceph and blade-servers in the same cluster (blade-servers use ceph storage and additional datastores) PVE 7.1-8 Thanks a lot for answers.
