corosync

Apologies if this isn't the forum for this. I'm testing things out with corosync and I'm confused by "bindnetaddr". I've posted a similar question here: https://serverfault.com/questions/1126948/a-more-detailed-explanation-of-what-bindnetaddr-is Though there's probably not going to be an...

Hallo, bei einem 3-Node-Cluster (A,B,C) und corosync mit jeweils link0 und link1. In der Doku steht, dass bei gleicher Priorität Corosync-Traffic priorisiert nach der link-Reihenfolge geht (niedrigste zuerst), also link0, bei Ausfall dann erst link1. 1. Wenn beim Node A der link0 ausfällt, aber...

I'm looking at using a low powered QDEVICE as my third NODE in a 2 node cluster. I don't have a local connection between the nodes or the qdevice, so I'll be relying on the WAN. Is corosync traffic encrypted, or should I consider protecting it in some way ie a VPN or other tunneling technique?

Hello Dear Proxmox Forum, We had two Proxmox VE nodes and one tie breaker nodes. We have added two additional proxmox VE nodes. When we checked the services, we realized some warnings. HA is looking fine in GUI. But in the CLI, it seems like there is something wrong. We really don't know what...

Greetings everyone, we needed to do some maintenance on a four node cluster. I moved the critical systems off of it but apparently the folks who were actually doing the removal and replacement of a node neglected to remove the noncritical VMs from it before using pvecm to remove it from the...

Hey everyone! Is there a way to display the latency among nodes, meaning from the node you currently are in (either console or WebGUI) to the rest of the nodes of the cluster? Like running the ping command to each node and displaying the end result together in a quick, useful and fashionably...

Hallo, ich habe heute gesehen, dass das Paket openvswitch-switch inzwischen aus den Proxmox Quellen ausgeliefert wird. Am 19.01. und 01.02. scheint das aber nicht der Fall gewesen zu sein. Das Paket aus den PVE Quellen triggert keinen Neustart der OVS Interfaces. Das Paket aus den Debian...

Dear Proxmox Forum I'am currently facing issues with my Proxmox Cluster. I have added SystemB to my cluster created on SystemA and since then I am getting the following error message: "Connection error 596: tls_process_server_certificate: certificate verify failed" I have tried unsuccessfully...

I removed a node from a two node cluster. I first had to set quorum_votes: 2 inside /etc/pve/corosync.conf on the remaining node. pvecm delnode pvec1n2 worked perfectly. The removed node is offline and not connected to the network. However the deleted node is still visible as a red entry on the...

I have been having a consistent and incredibly frustrating issue where a single node in my datacenter being rebooted causes the entire datacenter to fail and the web GUI to malfunction and become useless. I then need to log into the node(s) over SSH and either restart cluster related services...

Hi everyone, I'm having some performance issues with the Proxmox API on my cluster. As the number of users and virtual machines grows, the API becomes slower and slower to respond. I've already checked that the hardware is top-notch and the servers have enough resources, and I've also checked...

Hey yall, my 2 Node Cluster started to do weird things I cant explain - at least for now. All nodes run on the latest 7.3.4 release. Serv1 seems to be offline? It can be pinged, and I can open terminals (even from VMs), view stats etc. It is marked with a question mark from both...

Hello everyone, first time post, sorry if the formatting is wrong. So I started in a company and took over a proxmox cluster on Debian 11. After toying with proxmox for a few months, I decided to check the last thing on my predecessor's to-do list "keep the system up to date". Simple enough...

Related to this other thread, tagging @fabian as requested. I currently have a cluster with 13 nodes running. Everything is updated to the latest versions (except for the kernel which is pinned to 5.13.19-6-pve on all nodes because of some issues with live-migration on different CPUs). All the...

Hey there I'm experiencing a very weird issue with my Proxmox cluster (version 7.2-7). Everything is working just fine with 2 nodes, but when the third one is up then corosync stops working. This caused me a lot of troubles to have the third node join the cluster, until I restarted corosync on...

Hi guys! I stucked and need help. I have cluster (8 nodes) and tried add vLAN for corosync. When I modified corosync.conf file on non-master node, new file not modified on another nodes, but when I modified corosync.conf on master node, and restarted corosync service system rewrite file (delete...

Hi all, We have 12 node cluster with 6x ceph nodes and 6x compute nodes.(ceph nodes not running any vms). corosync connected via two links. one dedicated link and one shared (mgmt) link. Ceph configured with dedicated backend sync network as well We are changing some of the switch config and...

We need to replace a 10Gbe switch that is responsible for Link 0 in our cluster. The switch is failing lately with several unscheduled reboots. Every time the switch rebooted, our whole cluster went down and the individual nodes rebooted even though we have another two rings in the cluster...

Updated a Ceph cluster to PVE 7.2 without any issues. I've just noticed I'm using the wrong network/subnet for the Ceph public, private and Corosync networks. It seems my searching skills are failing me on how to re-IP Ceph & Corosync networks. Any URLs to research this issue? Thanks for...

Hey all. There seems to be two bugs regarding clustering setup and IPv6 addresses... 1. If you decide to use custom fe80:: addresses on a vlan/other interface, it may default to the primary network interface regardless (i.e. vmbr0 vs vlan###). 2. If you use a routed address, and it has a :: in...
