I have a three node hyperconverged cluster running PVE 6.2-6 and CEPH. After recovering from network problems involving VLANs reverting to an older configuration and waiting overnight, only one of the three nodes shows that it's online. A Fencing message went out this morning about one of the...
Hi I would like to set up a cluster with 4, max. 5 Nodes.
The catch is that during most times only one or two nodes will be running.
In my attempts so far I had often had problems with not having quorum even when using a qdevice.
The reason for the cluster is that if I need the extra power I...
Hello Proxmox community ! :)
I inherited a Proxmox 2-nodes setup at my new workplace and since it's running the EOL 5.4.15, I thought I would take a look at how to upgrade it to 6.x which is supported.
So I started the procedure here https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0 and...
I have a proxmox cluster of 3 nodes, (node1, node2, node3) but 2 days ago I started to see a picture of how the cluster is losing node2. This node is active, it works, the VM continues to work on it, I have access via ssh and web. All nodes see it on the network. This problem prevents VM...
I have (had) a 3 node Proxmox VE 6.2-11 and Ceph cluster. I'm modifying my config after install and some light use. Ceph is now on its own 10Gx2 LAN. I decided to dedicate a 1Gb interface and create a VLAN for corosync and attempted to modify corosync.conf before understanding exactly what...
Please help me understand for be clear:
Example for sure, all works fine, Ceph health OK, VMs are stored in Ceph, by default only node1 running a VMs:
node1: 1000 GB OSD (1 HDD)
node2: 1000 GB OSD (1 HDD)
node3: 1000 GB OSD (1 HDD)
node4: 500 GB OSD (1 HDD)
node5: 500 GB + 500 GB OSD (2...
Hello, I currently run Proxmox 6.1-7 with a few virtual machines including pfsense. I noticed the cluster option and it seemed intriguing so I created a cluster to try to learn more about it. I have my main node with all my VMs (called pve) and a second node (called proxmox). I need to remove...
we have a 2-node cluster without HA, named pve1 and pve2. pve1 replicates VMs to pve2. Both System run well until last week.
Both Systems run with Proxmox VE 6.0-2, PVE-Manager 6.0-4, PVE-Kernel 6.0-5
Now we get the following error messages
pve1 is marked...

Hi all. I wanna ask a few questions:
1. if proxmox nodes in HA cluster must have the same specs (ram, cores). Ive read the documentation for HA but im not sure if it is implied that nodes must have the same specs. i will create a test cluster anyways this week, but would save me time if i have...
We are running a simple cluster of two nodes ( pve 5.4.13).
After last update ans reboot of the two nodes, cluster lost quorum after few minutes.
We made several tests and tried many solutions showed in this forum with no luck.
omping command ran on two nodes returned this ...
Today, I rebooted one node and every node of cluster rebooted...
Now, the details:
I have a cluster of 4 nodes, where 1 is constantly down, because it has a hardware failure and we are waiting for spare parts. So, the cluster has 4 nodes, where 3 of them are alive.
Now, I rebooted one...
I just want manage my all node from single screen, but on Proxmox I think ths is not possible without Cluster system. In this moment Cluster system use Quorum because of that if I will close my any node then Quorum not allow me create any guest, or activate any quest..
We can any way...
i need to move my server rack with 8 Proxmox servers to different location.
My network interfaces where the quorum is running on internal network /not the internet/. I can move all servers at once, or better i preffer to move one after another to reduce downtime
How to proceed, when i do...
The question may be stupid, however I need to update the switch where the nodes in a cluster are (not with shared storage).
It’s clear that doing this will make the quorum unavailable, does it make any problem right now ? I mean, let’s imagine the switch dies or whatever, should I be...
in meinem cluster ist ein client kaputt gegangen. eine wiederherstellung ist nicht möglich, die fragen nach backup etc. erübrigt sich also.
dazu 2 fragen:
kann ich das cluster entfernen?
wenn das cluster entfernt werden kann, sind die laufenden VMs dann noch funktionsfähig...
I have 2 nodes in a cluster (i know it is not recommend...) and need to set the expected value from 2 to 1:
"pvecm expected 1"
But after i get still this output:
Expected votes: 2
Highest expected: 2
Total votes: 2
I'm trying to add a node to a cluster, but it keeps getting stuck at "waiting for quorum..."
I can get past it by doing "pvecm expected 1" on the node, but it doesn't actually add it to the cluster.
journalctl -f shows this over and over again:

One of our swichs is currently the IGMP snooping querier.
We plan to remove this switch which is an old Cisco 2960. Few days ago I decided to turn this switch off. All my V5 clusters lost quorum and many nodes rebooted.
Is it possible to configure a second switch to be the IGMP...
I am having a hard time adding SOME nodes to an existing cluster. all nodes are freshly updated and running same version of proxmox-ve, as follows:
# pveversion -v
proxmox-ve: 5.1-42 (running kernel: 4.15.15-1-pve)
pve-manager: 5.1-51 (running version: 5.1-51/96be5354)
