Hello! My goal is to have HA configured in a way where when a node goes down, the VM's get migrated to any other node that is available. When I set all nodes as the same priority the VM's go into a frozen state and do not get migrated to another node. When I have a node with a higher priority...

I love Proxmox's ability to make it super easy to set up a three-node HA cluster with Ceph. I like to use it for my VMs and SQL databases that require a lot of IOPS. This way, if one of the nodes goes down, my SQL DB VM can be quickly redeployed to another node. That way, if one of the nodes...

Heey I am a newbie to the community, so sorry if it sounds stupid, I have set up an HA proxmox cluster with three zimaboards on my local network that run a couple of VM's in failover mode. Now, the problem is this. When my house lits fire the whole system will collapse. Or when my router or...

Hello, Recently I created my first 3 node proxmox cluster. And I started experimenting. I have two questions that bother me: I've created replication jobs every 2 hours for one VM. Now if I shutdown proxmox node manually on which VM is running let's say 15 minutes before next sync, will the...

Hey everyone, after reading a lot and coming to the conclusion... Running a 2 node cluster productively with replicated storage (sync) is not feasible. I have the possibility to build a hardware setup with 3 nodes as follows, whereby these are really the *maximum* possible hardware capacities...

Hello everybody, I woul'd like to design an Hyperconverged infrastructure with 3 proxmox linked by DELL Fibre Switch S4112F in one hand and one DELL SAN ME4024 in other hand We have configure LVM on the the cluster's datastore. We have problème, only HA is available but, we have to have a...

Currently, I have 3 server setups and each server has 1 SDD for Ceph storage. If 2 out of 3 servers do not work the system is not operational for write. What will happen if I add one more server with 1SSD in the pool? Will my system can handle 2 server failure?

Hello, We're preparing to move to Proxmox from VMWare. As part of our high availability testing, I thought it would be a good idea to install and check out the HA Simulator. I've reviewed and followed he instructions in section 15.5 but am getting GTK errors. I had assumed the Proxmox PVE had...

Currently, I have 1 disk in each server(total 3) used for Ceph shared storage. I noticed that if 2 out of 3 disks are not working then complete ceph will also stop working. I am not sure if the same (n/2 +1) formula works here as well. Why It is concerning is because we are using CephFS as...

Hi, I have a small cluster with 3 nodes, configured for HA. Most of my data is on the same network as the cluster, on a Drobo connected with thunderbolt to a Mac, running Catalina. (Yeah, ewwww I know) I was planning on moving my services off the Mac to begin with, over to the cluster, and I...

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've configured HA and replication, but when I actually reboot a server, the failover fails stating that the volume already exists at the target node. Some helpful info: I have 8x nodes my goal is to have replications every 15m when there's an event that causes a failover, either a quick...

Hi all, I’m a little confused on how I would achieve this goal..... I’ve been tasked with migrating over our existing PFSense VSrv & setting up HA in the event a server fails or VM fails. I have setup a Proxmox cluster [ 2xDell R630 as PMS & 1xDell 3040Wyse running debian as a QDevice to...

I was going through the HA shutdown policy. Can you explain the difference between Conditional and Failover? Is failover a subset of Conditional?

I have 3 servers in the cluster, each server has- 1. 2 HDD hard drive and hardware Raid 1 for local storage and os storage 2. 1 SSD for Ceph use for HA. I have 2 VMs in local-lvm(ext4) and 2 in Ceph storage. My Ceph HA is working fine, it only fails when 2 out of 3 servers die. However I...

Indeed, Proxmox will not work when 2 out of 3 disks die in shared storage. My question is what happens when 2 disks in servers are RAID 1(shared storage) and one of the disks from two servers die? Will the Proxmox server use the raided disks or will it die?

I am already using HA, Ceph, 10G network, and shared storage. I noticed my VMs are restarting.

I have built 3 Proxmox server HA-Ceph with separate management and HA network using a 10GB switch. While testing I found that it takes around 30-40 seconds for a VM to migrate from 1 server to another. How can I increase the migration/fencing speed also how to setup live migration I notices...

I have read the docs on HA top to bottom and back to top: https://pve.proxmox.com/wiki/High_Availability I can't get my head around the resource scheduling, because: "The cluster resource scheduler (CRS) mode controls how HA selects nodes for the recovery of a service as well as for migrations...

Hi guys i am using proxmox already for some while, but since i had only one physically node available for some time, i have always relied on the automated backup snapshotting. In case a container failed, i have recreated a backup. backups are stored in the cloud for extra security. Now i have...
