Hi Proxmox community, Still new to Proxmox but was wondering why it is that if I am adding multiple nodes into a cluster they start acting like a legitimate chain and that if one goes down the entire chain breaks. I am working on two nodes for testing different filesystems and virtual machine...

Hello! I encountered a problem (in the attachment) when trying to create a cluster of two servers. Shows error 500 without additional information (in some threads there were similar problems, after the address there was still some description of the error), but mine is empty. I did everything...

I had some issues with my proxmox cluster and ended up starting from scratch. Im hoping you can help me with this dilemma. I have a 3 node cluster. One of them has Proxmox installed as a mirror on 2 SSD's the other two nodes only have single boot drives. I I installed proxmox on the server...

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...

Good afternoon dear, I have a problem with about 3 nodes of which all share a 10g fiber link for migration and vms backups. but even if the vms migration and restoration are slow some reason why so little speed 3 nodes config network nodes cluster config slow restoraution vm...

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...
