cluster

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, new Korean newbie is here. It's just a question, could I add physical storage as 1 node in cluster? I think, as far as I know, it's impossible because clustering requires pve os. It's a shame, but I've been working as a hardware engineer for less than a year. I hope anyone tell me truth. Thx.

Hi, I have set up a 2-node cluster, but I am unable to add a qDevice and while trying to fix it, I also broke container migration: Header Proxmox Virtual Environment 8.3.3 Container 127 (DietPi) on node 'pve2' template Logs 2025-02-11 21:27:55 # /usr/bin/ssh -e none -o 'BatchMode=yes' -o...

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...

Hello everyone, I am kinda new into all this so be patient with me. I am having a particular container with the name CT213 in my organization and I have the task to bring it back up. From the HA cluster pve trick we have , its the only container that doesnt want to start up. When i try to start...

Creating a cluster via GUI gets the wrong IP for the cluster. I have a node I'm already using and now I want to add a second one and form a cluster. The second one is freshly set up and has 0 guests. First node has 2 NICs, one in a 192.168 net and the other one in 10.x and is running opnsense...

Hello, I setup new cluster, with new hardware. I have 2 nodes, each nodes have 2 interfaces, 1 with public IP and one with private IP. When I setup cluster on node 1, I setup with vmbr which have private network. When I join cluster, I use cli to specify link0 with internal IP So, when I...

Good afternoon I'll explain my problem to see if I can solve it. I have a Proxmox with 3 nodes. In this one I have created a Windows domain and then with 2 nodes I have created a failover cluster with a file server role. In this file server I have created and shared some directories where I keep...

I’m looking for some guidance on expanding my Proxmox setup. Here’s my current setup and what I’m trying to achieve: Current Setup I have a dedicated OVH server running Proxmox. On this server, I have a pfSense VM that handles VPN access for employees to connect to the internal network. The...

Hi, I have a node 1 that I want to back up in DRP every day (not enough performance/money for BCP) I created a Node 2 with the idea that if Node 1 fails, I manually "switch" to Node 2 (just changing DNS)... I first thought about a PBS, but from what I see, it requires at least, 3 machines...

Hello there, people! Is it possible to create a Proxmox cluster using VLANs when the servers are on different subnets? Here’s my setup: Main Server: - IP Subnet: 192.168.1.x - Runs behind a router (192.168.1.1) - Has 2 NICs available New Server: - IP Subnet: 192.168.101.x -...

I am building a cluster with 2 PVE hosts and a quorum host. Each PVE host is running local storage with hardware raid. I would like have it set up in such a way that in the event of a node failure, all VMs running on one host can be restarted on another. Ideally with clustering, but replication...

I have this single node Proxmox and recently it froze out of the blue. I could not access its web interface or SSH into it. I ended up having to hard reset it. After the reboot, I went to the logs to try to make some sense of it, and found a bunch of "pveproxy" messages. Jan 22 20:21:05...

Hi to all just want to write it down, because it took my lots of time.I am trying to create a cluster with iscsi disks and lvm to test the cluster capabilities. My environment is cascaded,i mean .I have a Hp server with 3tb of disk and lots of memory. I installed Proxmox as Operating system...

I have set up a QDevice on a Raspberry Pi; with a 2 node cluster. All seems to be working and all nodes and the QDevice can see each other - see "PVECM STATUS" output below.... However, when I go to add a VM to HA, I am still getting the warning message - "At least three quorum votes are...

i have this issue with a server loosing connection to the GUI under certain workloads. or, the connection getting unstable. the VM's will for the most part keep running, though some might hang after a long time. i'm guessing it could be some kind of driver issue. i tried journalctl | grep...

Hi, I have a 5 node cluster setup with PVE 8.2.7, the nodes are using a pair of direct attached disks as an OS mirror and a ZFS pool on a 12 disk HPE D3600 Disk Enclosure using direct SAS connections to each node One of the nodes has lost connection to the ZFS pool. I am about to flatten the...

I've been giving "remote migration" a try for the first time today, moving machines live from a single host running ZFS to a new cluster running CePH. It worked tremendously well—without issues and on the first try—for all VM's but one, which always fails with the following errors. I tried...

Hi everyone, Merry Xmas! I hope someone can help with the following basic problem: I have just created my first cluster by adding a single new node. I would now like to set up the internal SSD in order to transfer some VMs over to it. However, it's not working like the master node. fdisk -l...

Ceph is great, but it needs some resources above the theoretical minimum to work reliably. My assumptions for the following text: you want to use Ceph because... why not? you want to use High Availability - which requires Shared Storage (note that a complete solution needs more things like a...
