corosync

I currently have a 4 node HCI cluster that's working quite well. It will be expanding to 8 nodes total and be used for critical services. All of the testing was satisfactory and management was duly impressed. I am reinstalling the cluster from scratch in order to ensure none of the testing bits...

Hello. I recently installed Proxmox in 1 one physical server (node). I was browsing around the node's settings when I noticed that under System, it is saying that the status of the Corosync Cluster Engine is dead. I did some Googling and learned that the Corosync Cluster Engine is how physical...

Hey Guys, I'm sitting with an issue, we replaced some of our servers in our cluster... And somewhere we made a mistake..Can someone please help me. We would like the public IP range to be the 129.232.156.xx range, and the ceph data sync ip range 10.161.0.xx The reason obviously being that...

Ich möchte nun mein Corosync-Netzwerk auf eine andere Netzwerkschnittstelle legen mit folgendem Wikiartikel. Zurzeit befinden sich nur 2 Nodes im Cluster. Meine bedenken sind nun das wenn ich die Datei gemäß der Anleitung ändere zur neuen Netzwerkkarte, as ich dies nur auf dem einem Node über...

Hi to All, I'm writing here since i can't find enough information about the issue I'm facing. I have decided to test 4 nodes cluster with proxmox . Everything was running just fine for the last 4 weeks.Ceph running good.Vm's running well no issues. Yesterday I have decided to update /upgrade...

Hello everyone, I have two proxmox ve 6.2 servers, one in France and one in Germany. I have setup a layer 2 vpn between the two sites (germany site beeing the server by itself [dedicated server hosting solution]). The two servers can contact each other through the vpn lan on all ports. I...

Hi, I am about to manually change the corosync config on my PVE cluster to introduce a 2ng Ring-Interface. I have read up on how to do that and although I am pretty sure, I got the config right, I was wondering if I could somehow prevent my nodes to be fenced, should I have messed up the new...

A couple of daya ago, we experienced an issue with a switch, which carried the corosync traffic for two of the 6 PVE hosts in our cluster. I can understand that PVE fenced those two hosts, but why did the other 4 ones rebooted as well? How can I fin out, what caused all my nodes to reboot...

Last night we tried to add a new node to the cluster, it stuck on joining showing the below messages: can't create shared ssh key database '/etc/pve/priv/authorized_keys' (re)generate node files generate new node certificate unable to create directory '/etc/pve/priv' - Permission denied We...

Hi all ,joined a new node(4th) to my existing proxmox cluster(3- node cluster) and it joined after 15 min showing waiting for quorum, after that it joined but after restart it is not joining the cluster. after 30 in or so it is joining again . any suggestion on what is wrong or what the...

Hallo, i am trying to setup a qdevice in my 2 Node Cluster. I am running a Debian10 VM on a different Server outside the cluster. When i am trying to connect the qdevice I get the following Error Message. :pvecm qdevice setup <ip qdevice > /bin/ssh-copy-id: INFO: Source of key(s) to be...

Guten Abend zusammen, wir setzen bei uns grade ein neues PVE-Cluster mit 3 Nodes auf (mit ZFS und Storage Replication). Netzwerkkonfigurationsmäßig würden wir gerne folgendes machen: 1G-Port: Corosync (10.0.11.x) (damit das sich nicht mit anderen Paketen in die Quere kommt) 10G-Port: Storage...

Hello folks, I keep putting off posting this but I'm looking for some advise on upgrading from PVE5.4-13 to PVE6.x I'm running a 3-5 node cluster where 3 nodes are all flash CEPH backed machines and another two machines are non-ceph game server hosting machines. The CEPH machines communicate...

I have a (possibly unrelated) problem where one cluster member's TOTEM keep generateing retransmits from other nodes or local timeouts. When I checked nodeC kept joining and leaving the cluster, about 50 per seconds. Restarting corosync resulted the same. It turned out however that on other...

So, I was following the directions to separate the cluster network, and things started to seem like they were going alright with the first node. However, when I rebooted the node, Datacenter view\Cluster says, missing ':' after key 'interface' (500). I then check the /etc/pve/corosync.conf file...

Hi there, We have a proxmox cluster, with each node in the same subnet. The cluster contained 3 hosts and everything worked as it should in the last years. Recently we wanted to add a new host to the cluster. This host is also in the same subnet, nothing changed in the network confugration...

Hello together, we have a 2-node cluster without HA, named pve1 and pve2. pve1 replicates VMs to pve2. Both System run well until last week. Both Systems run with Proxmox VE 6.0-2, PVE-Manager 6.0-4, PVE-Kernel 6.0-5 Now we get the following error messages on pve1: on pve2: pve1 is marked...

I am running PVE cluster over WAN (different datacenters across the globe). It worked all the time flawlessly and best suited my needs (of course no shared storage, LM or HA but still central management, easy offline migrations etc). Some time ago I've upgraded to PVE 6.0 and was able to run the...

Hello, I currently have a cluster of 2 promox with "two_node : 1" in corosync quorum setting. This cluster will grow to 6 servers. However, for reasons of maintenance it is possible that only 1 node is active on the 6. Because of the qorum vote, it is impossible to make a 2 node cluster work...

hi everyone! We are migrating our server to a different cloud provider. While reading a documentation, i read this: "Storage communication should never be on the same network as corosync!". Our server must have HA and data redundancy/ data high availability (using ceph). The problem is, our...
