quorum

Hi, I have setup 4x of my proxmox servers as a cluster so that I may hopefully move VMs around with ease. However, when I have only one server powered, the quorum mechanism blocks all operations. I understand that commercial IT does not have a concept "a server turned off on purpose" so this...

Hey All, I hope someone can assist. I have a 2 node cluster with PVE 8.2.2 running on both. I am trying to add a Raspberry Pi 2 Model B as a QDevice and I am running into the following problem. My 2 node cluster is fine but is obviously missing my QDevice. root@pve02:~# pvecm qdevice setup...

Recently, I've added multiple qdevices to several clusters running older versions of PVE without any issues, using command: pvecm qdevice setup 192.168.1.xxx -f and corosync-qdevice. Issue regarding certificate authentication. However, my latest 2-node cluster is running VE 8.2.2, where the...

Hello, From what I see, the corosync uses max number of cluster nodes+1 as a quorum for the cluster. So in 11 node cluster, 6 is the quorum. This is logically ok, but in real life scenarios, I need to have part or cluster to shutdown, and if shut down part is 5, then one more node and cluster...

Hi all, I had some network funkiness the other day and long story short, I lost quorum in my 5 node cluster. I got it back for all but one node, so I have a healthy 4 node (prox1-prox4) cluster right now. The one problem node, since there wasn't anything critical on it, I decided to reformat...

Hello, I have a 2+1 node setup (2 Proxmox nodes + 1 Qdevice on Raspberry Pi) and things were working quite well until one of the node went offline. Since that node is in repair, the cluster is running with 1 node and the Qdevice. I have not edited the cluster, the number of votes, etc. to...

Hello all, we are facing a strange issue. We have a two node Cluster plus QDevice on the latest PVE version with HA enabled on the VMs. We are currently in the process of testing the cluster. In order to test the fencing and HA recovery, we pulled the network from one of the two nodes (Node 1)...

Good morning, since setting up a cluster with 3 nodes (all running PVE 8.2.2), we've been experiencing an issue where they no longer communicate with each other after a maximum of 24 hours. The hosts are directly connected to each other via a switch. There is no load on the ports in the switch...

Hi Proxmox community, Still new to Proxmox but was wondering why it is that if I am adding multiple nodes into a cluster they start acting like a legitimate chain and that if one goes down the entire chain breaks. I am working on two nodes for testing different filesystems and virtual machine...

Hoping somebody can point me in the right direction. Today I upgraded the RAM in each of the 3 nodes of my cluster. I am using Proxmox 8.1.4 on 3 x HP mini PC's. All was working well until I noticed one of the LXC was not restarting. I realised my error, I beleive I had set it has HA but not...

I'm in the process of designing a new HA cluster across two locations. The two locations are connected together with multiple dark fibers and I would like to create an robust HA system that can migrate vm's between the locations. For storage I'm planning on using Ceph as I have experience with...

Hi there So I have two physical devices. Both are running Proxmox Virtual Environment Hypervisor. But only one node is up 99% of the time. I decided to have two installations of Proxmox VE and not Proxmox VE and Proxmox Backup Server, because I wanted to be able to do maintenance work or try...

Hello there, I'm pretty new here, but been playing with proxmox for 3 months now. I have 2 nodes and want to give my NAS a more respectable life purpose -- quorum device to achieve HA. Any directions on running a qdevice on my Synology? There's little documentation online on how to run it in a...

I currently have two proxmox hosts running in a cluster for my homelab. I am concerned about what will happen if one of the hosts goes offline. Whether due to temporary reboot or possible hardware failure. What is the best way to ensure that the remaining host works properly if one of the nodes...

So instead of ordering 1 expensive Dell/HP server I decided to buy 2 identical more consumer grade servers. Purpose is that if one fails the other takes over. Main components: MSI MPG X670E CARBON WIFI AMD Ryzen 9 7950X3D Processor (32 threads) 192 gig DDR5 RAM Crucial MX500 250GB SSD (boot) 2...

UPON LOST QUORUM (not indicated in the GUI), the attempt to access the node's OWN console ends up in generic: failed waiting for client: timed out TASK ERROR: command '/usr/bin/termproxy 5900 --path /nodes/pve7 --perm Sys.Console -- /bin/login -f root' failed: exit code 1 This is clearly...

Hello everyone, I currently manage a 19-node Proxmox cluster and I believe that during the weekend one of the nodes failed during the weekly VM backup job. Due to that event, the corosync service lost sync at cluster level and the nodes can't speak to each other (no quorum) and they have been...

Hello, we're planning to migrate our VMware infrastructure to a PROXMOX cluster in the next few weeks, and would like to take advantage of the zero licensing costs to create an HA cluster with shared, redundant storage on two sites. We have 2 datacenters on 2 different sites with a latency of...

Hi there I may have an unusual question. I have 4 proxmox nodes but one is in another location. In both location the proxmox running the router so the router is needed for the nodes to see eachother. How can I set them up so both location can run independently but I can manage them like if they...

I am trying to delete one of my nodes in my 2 node cluster. I have used the pvecm delnode [nodename] command and deleted the corresponding directory in /etc/pve/nodes, but the deleted node is still showing up in the WebUI. I saw in a separate post that some others have had to remove it from the...
