cluster configuration

Dear forum, I'm a bit lost about what might be the best way to set up a very small HA cluster: hardware: 2x identical nodes with i7, 16 GB RAM, 2 TB SSD, additional NIC with 2x 10 Gbe 1x Raspberry Pi as Qdevice UPS Is there a way to set up the cluster in a way that the two worker nodes are...

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...

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...

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...

Looking for some guidance on the how to correctly set the MTU for a cluster with a dedicated / separate network for Corosync traffic. I have a (rather) simple setup of 3 pve nodes, each having 2 physical interfaces: enp65s0: A mellanox fiber nic. Used by corosync in ring config (see below) for...

Hi all, I am running a 2-node cluster both on 8.3.2, After having a power outage, one of my nodes (Node 2) gets the "unable to resolve name ZYX" and Node 1 starts hitting the logs with "Totem retransmit" messages, I noticed that by adding on Node 1 in the /etc/hosts file the hostname and ip...

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...

I have a minsoforum ms-01 i9-13th gen and I plan to get another ms-01 but i9-12th gen as a secondary node. I use ZFS and I am trying to achieve extra head room along with zfs replicaton/HA. I know I need a third node to achieve quorum. So... I have another mini pc N5105 laying around but...

Hallo, ich würde gerne wissen, wie ich 2 Nodes aus verschiedenen Netzen zu einem Cluster verbinden kann. Ist dies nur über ein VPN möglich, oder gibt es andere einfachere Alternativen? Vielen Dank im Voraus für eure Antworten! ---- Hello, I would like to know how I can connect 2 nodes from...

Is there a way to force "cluster join" to provide IPv6 address rather than the default IPv4 address?

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...

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...

Hi guys, i was setup proxmox cluster just 2 node with standard subs, and wanted to achive HA so i used qdevice from my external cluster. And my question is, are these setup will be affected SLA license, or the qdevice just as voting quorum 2n+1. Thanks guys

Hello folks, totally new to proxmox clustering and just recently got 2 mini pcs for a home lab. As I was setting up the ceph cluster installation when I got to creating the osd, i couldn't target any disks as the single 1TB SSD I have is in use by proxmox. I followed the default configs for...

Proxmox cluster nodes losing all local and iscsi storage intermittently root@4tb-8tb-pve:~# iscsiadm --mode node --portal 192.168.12.17 --login iscsiadm: default: 1 session requested, but 1 already present. iscsiadm: default: 1 session requested, but 1 already present. iscsiadm: default: 1...

I'm trying to do what seems like the most simple thing, but am completely stuck trying to create a cluster for 3 nodes: I have a clean install of the latest Proxmox on two identical Minisforum MS-01 pcs. I have: Ensured time on both machines are in sync Added each machine to the others host...

Hello Team I am testing Proxmox 8.2.4 Setup with 3 Nodes Cluster In India: Node 1 BLR-ESI.local : IP 192.168.10.10 Node 2 MAA-ESI.local : IP 192.168.10.11 Node 3 DXB-ESK.local : IP 10.80.10.10 for creating a cluster. should be IP and Subnet same? In my case Node 1 and Node 2 use 192.168.X.X...

Dears, I'm preparing to setup 3 node Proxmox Cluster using Dell R740 for our production systems. I am trying to decide between using CEPH storage for the Cluster / Shared storage using iSCSI. Which is the best option for Shared Storage in case of 3 node Proxmox cluster? I need a reliable...

Hi All, I have a 2 node cluster I have added a second 1g nic to each and created a bond, i have also created a separate vlan for High availability traffic. When trying to migrate a container i get the following error: # /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=TEST-NODE01' -o...

Hi, I had two Nodes running for some time in Standalone. I now added a third node and made a cluster out of them. My Problem is that the Console of VM's is not working across nodes "Failed to connect to server". For LXC Console and node shell it is working fine. After some digging in the Forum...
