Hey all, Currently testing CEPH and Proxmox HA on a multi datacenter configuration (with black fiber, so sub ms latency.) I tried to recreate the worst scenario possible : what if all nodes lose the corosync layer? This should never happen, but that's what the lab is for. I'm using Proxmox...

I have a 3 node cluster. I had to make some changes since one of the hosts had a drive fail, I reinstalled proxmox and killed the node using: pvecm delnode <node-id>, then readded the node, I then had some issues with the digital fingerprint, ran the command proxmox gave me on all remaining...

I had to migrate one of the nodes of my four node cluster to another data centre. The IP address had to change. Now I've googled how to change the IP address of the node that is currently down but I'm struggling to find a HOWTO or concrete information that doesn't overlap or contradict. Are...

I have a 3 node cluster, two have been evicted from the cluster leaving one with live VM's. What will happen to the live VM's if I remove the cluster altogether from the last node? Ceph is not being used.

Hi everybody, preparing for a production use of proxmox I'm testing it in a virtual environment with the configuration that I'll use after. I've virtualize two PVE and one PBS, create a cluster and used the PBS for the third vote for quorum using the guide found on the proxmox site. Everything...

Hi, I have a small cluster with 3 nodes, configured for HA. Most of my data is on the same network as the cluster, on a Drobo connected with thunderbolt to a Mac, running Catalina. (Yeah, ewwww I know) I was planning on moving my services off the Mac to begin with, over to the cluster, and I...

Hello Proxmox Community, I'm a long-time lurker, and today I'm the one posting :) I'm trying to set up an SDN (Software-Defined Networking) on a cluster of 2 Proxmox servers to create a high-availability (HA) datastore using OpenMediaVault (OMV) and DRBD (one OMV instance on each Proxmox...

Hello! I'm going to add a few servers to my PVE 6.4-14 cluster, can i install 8.1-2 and add it to cluster to move some VMs to 8.1-2 and then upgrade 6.4-14 .. thanks

I found myself in a dead lock situation: At first I deleted my cluster, in other words, I separated my node from the cluster. Then I realised that one CT is down and locked. I wanted to start it, but that wasn't possible because of the locked status. So I tried to unlock the CT via qm unlock...

Hi Everyone, I have a proxmox cluster and today I added a new node to it. However once it was added I'm now getting an error on the new node: no such logical volume pre/data (500). Not sure what I can do to fix it? Is there an easy way to remove the node and re-add it?

So I have removed all the nodes from a cluster except the last one. This last one is still hosting VM's. Can I remove the cluster without taking down the environment or any of the VM's? This is not a Ceph cluster.

Hello, guys, I have created a cluster with 2 nodes (planning to expand to 3 nodes in the future). However, I'm facing an issue. I have two dedicated servers, each equipped with RAID 1 consisting of three SSDs, and on both servers, this volume is identified as /dev/md4, boasting a capacity of...

I have a cluster of around 20 nodes, Proxmox 8.0.4 +ceph (on 4 of them) all have the same configuration of chronyd. and most of the time everything works. recently (in the past month) i started to have issues with time sync. usually it comes after a power failure, some servers are out of...

Hello all, I am fairly new to Proxmox so forgive me if I am on a completely wrong path. I have three nodes into a cluster and a shared NFS storage (truenas). I have made a template VM on host1 and have successfully moved the disk on the NFS share. But, when I want to clone the template with...

Hello, I am running a couple 20+ node cluster today and we are deploying VMs using terraform (bgp/proxmox) Since as far as we know in the API you have to specify which one of the nodes you want to deploy the VM to we have created a javascript in between Proxmox and terraform that translates...

I've set up a cluster of 3 machines, and have added 5 LXC's for a Minecraft server that I plan to initially expose limited number of users online, those in school Minecraft club. Proxmox has the Firewall at the datacenter level, server level and VM, LXC level. For Minecraft the servers are set...
