Hello! I'm going to add a few servers to my PVE 6.4-14 cluster, can i install 8.1-2 and add it to cluster to move some VMs to 8.1-2 and then upgrade 6.4-14 .. thanks

I found myself in a dead lock situation: At first I deleted my cluster, in other words, I separated my node from the cluster. Then I realised that one CT is down and locked. I wanted to start it, but that wasn't possible because of the locked status. So I tried to unlock the CT via qm unlock...

Hi Everyone, I have a proxmox cluster and today I added a new node to it. However once it was added I'm now getting an error on the new node: no such logical volume pre/data (500). Not sure what I can do to fix it? Is there an easy way to remove the node and re-add it?

So I have removed all the nodes from a cluster except the last one. This last one is still hosting VM's. Can I remove the cluster without taking down the environment or any of the VM's? This is not a Ceph cluster.

Hello, guys, I have created a cluster with 2 nodes (planning to expand to 3 nodes in the future). However, I'm facing an issue. I have two dedicated servers, each equipped with RAID 1 consisting of three SSDs, and on both servers, this volume is identified as /dev/md4, boasting a capacity of...

I have a cluster of around 20 nodes, Proxmox 8.0.4 +ceph (on 4 of them) all have the same configuration of chronyd. and most of the time everything works. recently (in the past month) i started to have issues with time sync. usually it comes after a power failure, some servers are out of...

Hello all, I am fairly new to Proxmox so forgive me if I am on a completely wrong path. I have three nodes into a cluster and a shared NFS storage (truenas). I have made a template VM on host1 and have successfully moved the disk on the NFS share. But, when I want to clone the template with...

Hello, I am running a couple 20+ node cluster today and we are deploying VMs using terraform (bgp/proxmox) Since as far as we know in the API you have to specify which one of the nodes you want to deploy the VM to we have created a javascript in between Proxmox and terraform that translates...

I've set up a cluster of 3 machines, and have added 5 LXC's for a Minecraft server that I plan to initially expose limited number of users online, those in school Minecraft club. Proxmox has the Firewall at the datacenter level, server level and VM, LXC level. For Minecraft the servers are set...

I'm interested in configuring high availability but I couldn't find information about how it works with different hardware configurations. I have a really beefy main server, and my other servers that would be in the 3 HA node aren't as powerful. 128 Cores 4 TB of RAM 44 Cores 1 TB of RAM 88...

Dear Forum I would like to upgrade an existing PMG7 cluster with two nodes (1 master and another) to PMG8 without an in-place upgrade. Is there a step by step guide for this?

Hello, I am running a 2 node cluster with an external QDevice. So I am looking for a solution to force start a VM even just 1 node is online and the QDevice is not reachable. That VM is not running on a shared storage so I don't care about split brain. I don't want to set expected votes or...

Hi, I've seen few threads about cloning the boot disks to another disk/SSD, some used clonezilla (which, as of this moment, still having problems cloning the Proxmox boot SSD), some use dd. My problem is a bit different: I have a cluster of 3 nodes (prox,prox2,prox3, I've created the cluster...

I especially want to know what protection mechanism the PVE cluster has to allow the host to automatically restart. Environment: There are 13 hosts in the cluster: node1-13 Version: pve-manager/6.4-4/337d6701 (running kernel: 5.4.106-1-pve) Web environment: There are two switches A and B...

Hello, since yesterday nothing works anymore on my Proxmox server, I have already reinstalled both servers, with the official iso file, but on my first server "Proxmox" the cluster does not work, there is always the one with the question mark shown, and when I go to the server in...

Hello, I would like to set up a Proxmox HA cluster with 2 nodes. I can't use Ceph with only 2 nodes, so I wanted to try replication. With replication, you can set the container to be replicated every 15 minutes, for example. But then I asked myself a question: If my container is running on...

Hi. I'm really new to proxmox. I will try to back up my "proxmox" node's vms to "dl380" node. They are in cluster. I have a directory type storage on "dl380" node with the following settings. When I try to run a backup job I received the following error message. I checked the systemctl...

Hello. Does anyone know why proxmox cluster uses Link 1 instead of Link 0 to migrate VMs? My Link 0 is 10G network card and Link 1 uses 1G card. I was wondering why migration is so slow so I checked NIC traffic with vnstat and I noticed proxmox cluster data goes thru backup link. Is there...

Help, has anyone encountered a similar problem, a cluster of 3 nodes, one random node freezes, with a VM backup task, restarting networking.service helps and the node comes to life, the VM comes to life after unlocking qm, but the network on the VM does not work if you migrate VM to another...
