high availability

Hi, A vps crashed in the middle of the backup and the HA-service tried to restart and migrate the vps to no avail. Because of the backup the vps was locked and could not be restarted or migrated by the HA-service. Is there a possibility that the HA-service can abort the backup to unlock the...

Hello all, I have been thinking of setting up Shared Storage for 3 Proxmox nodes. This will mean 4 systems (NAS, pve1, pve2, pve3). The NAS (for lack of a better name) will share to the 3 nodes using NFS or SMB and will hold all the VMs and CTs only; it will not be used as a multimedia server...

So I just joined a startup as their sysadmin, my role is to build the server from scratch both hardware and software. My experience is setting up a single node Proxmox homelab with things like OMV, Emby, nGinx Reverse Proxy, Guacamole, .... so I'm a noob but I'm learning. The use-case is...

Hello, Running PVE 7.1-8 (3 Node Cluster) I'm looking for the best method of getting pfSense failover for my situation. I've tried just about every configuration I could Google up and can't get it working. I'm hoping someone may have an idea of what I direction I could go. I only have one...

pve-manager/7.0-11/63d82f4e (running kernel: 5.11.22-5-pve) - (5) node cluster, full HA setup, CEPH filesystem How do I prevent HA from rebooting the entire cluster? 20:05:39 up 22 min, 2 users, load average: 6.58, 6.91, 5.18 20:05:39 up 22 min, 1 user, load average: 4.34, 6.79, 6.23...

Hi everyone, I have setup a 3 nodes Proxmox 7.0-11 cluster, each node has 3 HDD drives, the first drive is used for Proxmox and the others are OSDs. I wanted to test HA by removing the last disk of the first node (which doesn't contain Proxmox), but when I remove it the node reboot. Is this...

Hi We have been doing some testing on HA with PVE and Ceph, which has given very possitive results in terms of our goals with exploring the setup. From our testing, we have found two issues that we had not really expected 1. When a host has failed and comes back online, VMs are not migrated...

Hi We are looking into hardening our infrastructure to better handle outages due to network or hardware failtures. We use OVH dedicated physical servers for our infrastructure and currently have 3 node PVE cluster. This cluster is currently configured with 2x4TB nVME drives per node, with one of...

Hey all; I've made use of Proxmox for a while and I'm looking to take my first few steps into ceph -- I have 3x QCT QuantaGrid SD1Q-1ULH that I will be making use of. Each of these nodes have a Xeon D-1541 with an OCP Mezz 10Gb SFP+ (QCT Intel® 82599ES dual-port 10G SFP+ OCP mezzanine) and...

Hi, we are migrating from a VMware ESXi setup with a NetApp NFS based shared storage. We also did use NFS filesystems for mounts like /home or /root and application filesystems like a shared /var/www within our virtual machines and host-specific filesystems like /var/log. Most of our...

Hello, I have some doubts on how High Availability can work in ProxMox. I'd like to create an HA enviroment to host my personal websites and also to lear more about HA. I imagine I have 3 identical server and all of them are part of the same cluster. I read about HA with local storage, shared...

Hello. I've set up a cluster with physically separated cluster network but it is not doing what I expect it to do. Here is my lab: [node1 ~]# pvecm status Cluster information ------------------- Name: clustest Config Version: 3 Transport: knet Secure auth: on Quorum...

Hi, We are trying to deploy an HA storage environment on Proxmox using multipath, a Synology NAS (RS1619xs+) and an iSCSI SAN, and we cannot get the multipath driver to manage the iSCSI LUNs. We need a little help to go further or to interpret the errors we are commiting. This is what we are...

I've had this problem for a while here now, and I've turned the internet upside down trying to figure it out, but there is very, very little information out there about this specific warning. It is extremely consistent and reproducible in my PVE setup though, so I figured I'd ask here! May 28...

Is there a correct way to restart a node (mostly for applying kernel updates)? I have about 20 virtual machines and containers that should not go down ever unless planned. So I have set the all as HA. When I shutdown a node, the VM's / LXC's shut down instead of migrating to the node next in...

Hello I have read documentation and topics on forum about this subject but cannot find a clear answer (and the thread How does Replication work in a HA environment? is quite old , 2017) If I have a replicated VM betwen the 2 nodes I'll put this VM in HA configuration, Will HA process use the...

I had a server die this past week and I removed it from the infrastructure. I can confirm that the server is out of commission and is pulled from the rack. I removed the node and all is well, or so I thought. The cluster is giving me an issue with regards to it seeming not being able to find the...

Hello, We have a 8 servers Proxmox 6.1-5 cluster (last updated 2 days ago) that is configured for HA with "shutdown_policy=migrate". However we noticed that this sometimes works and sometimes doesn't, having a VM with HA enabled running on a host that is rebooted or powered off can result in...

I'm trying to figure out how I could install a pfSense VM and make it HA. I have a ceph cluster of 4 nodes (but there will be nodes added regularly), so I can give each node a public IP address on one of it's ethernet ports. Creating a bridge and adding that to the pfSense VM will give me a...

Hello Proxmox Community, I am interested in live migration. Recently I read posted accorss the fron the XCP-ng's website the phrase "Live migrate your VMs all around the world, without interruption" However I did not find any detailed sources which stipulate that live migration was actually...
