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...

detected the following error(s):

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...
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...
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...
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:
proxmox01 - 10.2.4.1
proxmox02 - 10.2.4.2
NEW IP should...
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...
Got a non-std corosync config here with a static nodelist and 2x rings across each their redundant switch networks:
This imposes some issues when wanting to use the firewall, as PVEFW-HOST-IN/OUT chains says:
Could I modify these standard created chains to allow for both our corosync rings...
TL;DR: What's the correct way to specify a multicast address in v4.1 in a way that proxmox is aware of it and won't overwrite it in the future?
Just installing 4.1. My network admin has specified a multicast address which I must use.
In a one-node config, I figured out...
I have two servers running PVE 4.1 and I just made them into a cluster. Everything seems to work fine, but I see in syslog on both systems corosync-related error messages every second or so:
