Hi!, 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...

Hallo zusammen, ich weiß, unter diesem Begriff findet man 1Mio. Treffer unter Google... Leider hilft mir keiner davon weiter. Ich habe eine bestehende Cluster-Umgebung mit drei nodes. Diese läuft noch unter pve 4.4 Jetzt möchte ich beginnen die Hardware zu tauschen und die Umgebung upzudaten...

Hi all! 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...

Hi, 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...

Hi, 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) Node 1 Interface 1 : 192.168.0.10/24 GW 192.168.0.1 Interface 2 : 10.0.0.1/24 no GW Node 2 Interface 1 : 192.168.0.11/24 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 ) root@urd:~# systemctl --stat=failed...

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). parse error - uncexpected '}' (500) I am sure this is my own fault - I modified corosync.conf to add a separate corosync network as backup as per the...

Hi everyone, 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: Jun 29 01:33:40 waifu-pve...

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...

Greetings! 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...

Hi! I have 4 nodes cluster. I want to have a quorum when two of them are offline. I tried setting auto_tie_breaker in corosync.conf and corosync-quorumtool -e 2 but both methods didin't work. How to configure that? And another question, why changing corosync.conf after creating cluster with...

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...
