    Hi all, I'm new to Proxmox, for many years I've worked with VMware, but I'm start to enjoying Proxmox very much and now I'm migrating all the solutions I manage to Proxmox. One of those solutions is a VMware cluster that I intend to replace with a Proxmox Cluster. So, I got 3 servers, with...

    Replication Failure

    I'm trying to setup replication between two nodes to have a copy on each node as well as backups in PBS and TrueNAS. I have setup PBS and will do TruNAS later. I currently have both nodes setup with ZFS pools though they do have vastly different configurations. Each node has it own local ZFS...

    Greetings all, I am new to Proxmox and currently investigating the possibility of setting up a scalable virtual infrastructure using Proxmox VE and have what is probably a very "noob" sort of question. Is there a requirement for the hardware nodes in a cluster to be matching (i.e. CPU, RAM...

    [SOLVED] Broke my cluster

    Hi, I have a 3-nodes cluster that was configured as follows: node1 with ip 192.168.1.120 node2 with ip 192.168.1.121 node3 with ip 192.168.1.122 So I wanted to change and make it coherent (node1 with ip 192.168.1.121, node2 with ip 192.168.1.122, and node3 with ip 192.168.1.123). I started...

    Should redundant corosync links be on seperate VLAN?

    After reading through PVE CM Redundancy, I am left wondering whether or not there is any reason not to use the same VLAN for the two separate physical corosync links? I see the example shows what presumably are separate subnets, but I see no explicit mention on whether or not such a logical...

    Any way to not include PBS storage from Total Storage in Cluster Calulation?

    I understand the way The Cluster Resources for Storage is summed up for all attached pools, but I do not consider the PBS as actual usable storage unlike a NFS mount for example. Is there anyway to allow PBS backups without including the Storage pool to each node and/or remove the PBS storage...

    Setting Up a Dynamic Proxmox Cluster with Normally-Off Nodes (Non-HA Setup)

    Hello Proxmox Community, I'm working on a home lab and need to save power, so most of my nodes are powered off most of the time. My goal is to set up a Proxmox cluster that can dynamically scale as nodes are powered on and off without requiring high availability (HA) or strict quorum. I’m fine...
