What method is used to share storage once a host is joined to a new cluster? I've been looking for some sort of config file but haven't been able to find any information about it. Does it use the Corosync network?
We have 2 nodes Dell M630 each node have Qlogic 57810-k dual port connected to Dell MXL stack. These two ports are configured as bond0 (LACP bond). On top of the bond with vlan 20 is configured vmbr interface for corosync/cluster
But it looks like multicast traffic is not passing.
Ich hab schon mehrere threads zu dem Thema gefunden aber wußte nicht wo ich meine seltsame Beobachtung einbringen könnte die vielleicht zur Erhellung der verschiedenen beschriebenen Probleme

Hi I was wondering if this network configuration is supported for corosync ?
The vmbr0.4093 is the corosync network and the vmbr0.60 is the managment network.

I'm trying to evaluate virtualization platform for my future project and proxmox seems interesting.
had installed in two node and works fine for few days. However after a switch failover one day , one of my node started giving issues. All processes are fine except for corosync . It shows...

I found next situation:
when link is unstable, (such as network card 10Gbps attached to switch by connectors RJ45 w/o gilding - contacts on network card and on connector can be oxidized), switch can up/down links and after which corosync goes "crazy" - starts loading one core of the...
I currently think about using sheepdog for my shared storage cluster. I have 4 Intel NUCs for this, but I also have some other machines where lot of storage space is wasted currently because not used.
So one idea would be to enhance the sheepdog cluster to these too.
There is the special...
Let's admit we have a 3 nodes cluster.
Each node have 2 interfaces, first one (vmbr0) for VMs + corosync and the second one for corosync (via RRP in passive mode)
Interface 1 : 192.168.0.10/24 GW 192.168.0.1
Interface 2 : 10.0.0.1/24 no GW

A question regarding upgrading a proxmox cluster and corosync: If I start with a simple setup, ie I don't have a separate NIC and network for the proxmox cluster and ceph, how can I upgrade that later by adding the hardware to the nodes of a cluster?
I mean, /etc/pve/corosync.conf can't be...
Hi, I wanted to create a Proxmox cluster and roughly followed this ( myatus.com/p/poor-mans-proxmox-cluster/) procedure.
But I fail because the second node can't join the cluster because Corosync complains.
Node 1 = skuld (10.8.0.1)
Node 2 = urd ( 10.8.0.2 )

On a 3 nodes cluster (with HA VMs), since few days, I have Totem retransmits everyday at 06:00 (during few seconds).

I have an issue where I get the following error when trying to create a new HA resource in my cluster (Datacenter -> HA -> Resources -> Add).

I am sure this is my own fault - I modified corosync.conf to add a separate corosync network as backup as per the...
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.

Hello and thank you for making such a great product.
I need a little bit strange configuration of Proxmox cluster:
1. I need three nodes cluster;
2. node 1 and node 2 have the same hardware configuration and are not used by now (no storage/vms).
3. node 3 is running in production with multiple...
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)
I have created a new cluster with 4 nodes, the problem is that when I reboot them all of them are working, but after some minutes some of them says that are disconnected.
When this happens I execute in the shell node:

After execute this command the node is online...
I recently had to add a host to an existing cluster. By some reason I did it using web interface, not command line. The host added, but its ring0 address is now named with its IP in contrast to the rest that have ring0 equal to the hostname. I have 2 questions so far:
1) Why it...
