high availability

Good evening, Started my journey with Proxmox, networking,etc. I recently created a modded minecraft server on my main pc that I want to eventually run on Proxmox. I made my first node and the a second, from there I created a cluster because it seemed cool. Then I found out that "even" clusters...

Hallo Zusammen, Im Proxmox Cluster ist eingestellt dass VMs über HA migrieren sollen, wenn ein Knoten down ist. Dies hat allerdings bei einer Node mit vielen VMs zu einem unerwarteten Verhalten geführt. Die Migration ging sehr lange, und bei ca. 50-75% migrierten VMs ist der Knoten einfach...

I run a frigate CCTV system on my two node cluster with high availability enabled. Obviously a live migration cannot take place and it's not the main issue I have. Node Failure In the event of a node failure, everything works perfectly. The VM migrates from the first to the second node using...

Hi! found myself stuck on a weird situation. After a power failure during night, my nodes got affected. After restarting, a single virtual machine i was testing to learn about High Availability got separated from its disk. I'm using local storage on every node, so the environment is a 3 nodes...

I currently have two Mini PC with Proxmox in a cluster along with a raspberry Pi QDevice. Each server has a public 2.5gbe and a private 2.5gbe (interconnected between the servers on separate subnet). I am using ZFS on NVME on both servers. I am currently using HA w/ Replication. 1) Is...

When a VM is protected by HA and a poweroff runs inside the VM the VM is happily started again by the HA manager. Is it possible to tell the HA manager from within the VM (via qemu-guest-agent maybe) that the VM should stay powered off?

Hi, I'm trying to set up SAN storage using fiber cables. I have 5 servers running Proxmox, all of which are in a Proxmox Virtual Environment (PVE) cluster. Could you provide a detailed, step-by-step guide on how to set up SAN storage that will be accessible to all nodes in the cluster.

I'm currently managing a Proxmox cluster with three nodes configured for high availability (HA). I've observed some behaviors regarding LXC container management and failover mechanisms, and I'd appreciate any insights or clarifications you might offer. Preventing Duplicate LXC Instances: In our...

Hello, I would like to set up a Proxmox cluster at OVH. 3 Hosts with CEPH for HA. I was thinking of using the Advance 3 offer from OVH. I've mapped out a solution in my lab with 3 machines, each with a 1TB SSD. After configuring a 1TB CEPH datastore including the SSD for each host. Hot VM...

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...

I was wondering what would be the best course of action to setup HA for the Proxmox web portal? I am currently usin HAProxy but I noticed that when I go into a console of one of the VMs, it does not use the same server that I am on (connection is probably not sticky). I was thinking a better...

I have 2 networks in my server management and HA. I am creating a cluster which one should I use?

It's nowhere in the PVE official docs, but corosync does support last_man_standing and when used with HA it is suggested to also set wait_for_all. I found some previous threads, but not in relation to HA. Now I understand the official PVE endorsed way would be to just use a qdevice, but this...

Test scenario, 3 nodes - pve{3,4,5} - default PVE install (LVM, so no ZFS), 1 container set as HA, started on pve3. Figured out replication not possible without ZFS, alright, never mind, pve3 went down, HA attempted to restart CT on pve4, no volume available, still understood. Now when pve3...

Hello, I am working on setting up a cluster with where the VMs are on local storage but use/sync to the shared storage for HA and Cluster options. The hardware I have is as follows: 3 proxmox clustered machines (will be more but 3 for now) - Each has local nvme storage Each has access to a SAN...

I have a 28 node PVE cluster running PVE 7.4-16. All nodes are Dell R640/R650 servers with 1.5 or 2TB of RAM and Intel Xeon Gold CPU's. They all have 2 x 1GB NIC's and 4 x 25 GB NIC's. We are connected to an external CEPH cluster. Node network config: 1 x 1GB NIC is used for...

Hello, can someone help me? I wanted to test the Migration from one server to another. So I have done manual replication, that in both servers are the same last version of vm disks. So I turned off the network ports, so it started to migrate to another pve node, but it was not live, because HA...

Hi everyone, I was adding another node to my cluster today (node 4), and during the process, node 1 decided to crash. This triggered the HA, and it began spinning the VM up on node 2. The HA migration failed, and the hard disk was never moved. On node 2, I see the VM and the config; and on node...

Hi, We would like to use HA pair of Proxmox servers and data replication in Proxmox therefore shared storage is required (ZFS, BTRFS?). We also want to use Hardware RAID instead of ZFS erasure coding or RAID in BTRFS. Does proxmox define what commands/setitngs are required in order to setup...

Hello. I'm new to proxmox and I'm trying to configure a High Availability Cluster with two nodes. I have some VMs in one of the servers (node 1), and, in case it gets down, I wanted them to continue operating in node 2 without losing information. Currently, I am using an external vote to...
