Hello Everyone, Has anyone tried using the below method to achieve HA on TrueNas with Proxmox. Create a virtual machine with 2 identical disks Each disk is on a different storage ( NFS mapped to dataset on Truenas ) Set both disks as bootable. Install operating system inside virtual machine...

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...

Hello forum members, I plan to test HA feature in my 3 hosts cluster environment. Read up to achieve HA, i need a central storage as VMs / containers repository. For a test, i wanted to use my small Qnap storage and share the LUNs via iSCSI. Hope some experts here can guide me and/or share...

I have an installation with 4 nodes. It´s possible connect a USB device to a VM in other node. I suppose that this is specially important in an HA environment. Thanks

Hi, what is the recommended procedure to shutdown a complete PVE cluster including HA resources? The manual only talks about maintenance of single nodes, but sometimes it is necessary to shutdown everything. We have observed that a simple shutdown on all nodes is not sufficient as HA fencing...

We have a Proxmox cluster comprising two identical large machines, with 120 cores and 370+ gig of memory, and with each machine having two ZFS disk pools, Tank1 of 50TB HDD, and Tank2 of 2TB of SSD, and a third less powerful machine with just one ZFS pool, a mirrored paid of 10TB disks...

I have read through the documentation and I'm not sure I'm following it well because I'm not even sure if what I want to accomplish is possible with Proxmox or not so I thought I'd ask here. I have a Proxmox node setup and hosting several containers and VMs. This started as a hobby and chance...

Hey how’s it going all, I’m doing a bit of experimenting and wondering if it’s possible to have several Proxmox nodes each with their own local storage, and the VMs on that storage mirrored/synced onto a shared store; then HA setup so if any Proxmox node goes down, the VM is read/run/hosted...

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...
