Hi there,
I'm currently trying to setup a 3-host cluster in a datacenter where multicasting isn't possible (Hetzner) so after I read about UDPU in https://pve.proxmox.com/wiki/Multicast_notes and some tests locally I was fairly positive that this is going to work.
However I only was possible to...
Hello, we have a cluster of proxmox 5 with four nodes in unicast (IPv4) and the syslog of the four nodes is appreciating the following message:
... corosync[1491]: alert [TOTEM ] Invalid packet data
... corosync[1491]: [TOTEM ] Digest does not match
... corosync[1491]: [TOTEM ] Received message...
Hi all,
Playing with Proxmox, and it's been a blast.
Had a small question, is it normal for Corosync to log the following lines every 2 seconds, on all nodes ?
Jan 15 02:18:09 kvm4 corosync[24830]: notice [TOTEM ] A new membership (192.168.220.20:765924) was formed. Members

Howdy all,
So I'm trying to get an odd question answered here that I can't seem to find. I know that Proxmox uses Corosync to create and manage a cluster which will let you use a single interface to manage multiple physical nodes, as well as handling HA and live migrations, but from everything...
Hi guys,
Experiencing the same issue on 2 separate clusters of different sizes in two different locations with completely different hardware.
Issue is that after a week or two of regular cluster operation memory usage by corosync grows to crazy levels for instance currently on a node it's at...
Hi,
I have a cluster with 3 nodes, after a power outage two nodes restarted and are not joining the cluster, corosync is not running and when trying to restart the service the log shows the following error:
"[CMAP ] Received config version (4) is different than my config version (5)! Exiting"...
I needed to change the IP Address of a proxmox server. Which I did from the WebGUI.
However now I've rebooted the server the VM's will not start. Get an error message "cluster not ready - no quorum? (500)"
Doing a pvecm status I get "Cannot initialize CMAP service"
So I checked the...
I have a cluster running, and I am trying to add a new node but receive the following error

Hello everybody,
I'm writing this short article because I spend myself a lot of time by finding the right configuration to get this working.
First of all: A 2 Node Cluster is not a very good way to create High-Availability or even Fail-over scenarios because corosync is not able to create a...
Hoping someone would be able to assist,
I'm trying to configure a 3 node cluster, 2 nodes on the same physical network, and another node remotely.
this other node sits behind a Pfsense firewall that has a site-to-site vpn connection to my pfsense router.
i'm able to cluster the first two...
What is the preferred and safe method to prevent a node from rebooting due to (observed) loss of quorum? Or in other words: how to temporarily disable fencing on a node?
Hi,
I'm having a strange issue on my proxmox4.3 cluster: from time to time all nodes appears red in web GUI. Gui also sometimes is not reachable at all and I have to restart nodes..
I figured out that the logs always shows these lines, even if all is marked green:
Reading the forum have lead...
Hello everyone,
I corrected this issue but wanted to share my experience with setting up a cluster following the Proxmox Wiki after I had already changed the IP address of vmbr0 on both Proxmox hosts. I installed Proxmox on two platforms with hostnames: proxmox1 and proxmox2. Both of the...
Hi,
I have a cluster setup with 2 nodes (proxmox01 and proxmox02). Proxmox01 is my primary node, then Proxmox02 is my second.
What I noticed is everytime proxmox02 gets a bit loaded (system load reach around 2.0) because of the "kvm" process, it automatically get disconnected from the cluster...
Hi, I'm currently in a situation that I need to change the IPs for my proxmox nodes. For the reason that the current IP that we used is unfortunately conflicting on the weave network that we used as the bridge interface. So:
current IP:
proxmox01 - 10.2.4.1
proxmox02 - 10.2.4.2
NEW IP should...
Hi,
I have a fresh setup of Proxmox VE 4.2-15 cluster with two nodes running, Proxmox01 and Proxmox02.
Using Proxmox01's UI as my management UI, I'm able to deploy and setup a VM on Proxmox01 with no sweat. However, I'm having an issue deploying a VM in Proxmox02 (using Proxmox01's UI). I was...
