cluster

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...

Hello, i am planning to move my one node Proxmox server with VMs to a new 3 node Cluster with Ceph Pool. Now are my questions: 1. Whats the best way to move the VMs to the according Ceph Pools on the Cluster, with minimal downtime. 2. Is there a way for testing to just copy a VM from the...

I have just finished up a full 3 node cluster/HA deployment in the lab, and I am finding it to be a time bomb for small/medium businesses due to too many single points of failure for the cluster. My concerns revolve around cluster corruption due to power failures outside of a data center...

Hello! I have bough 2 new servers and I have created cluster with those 2 nodes, now I wanna add old node which has al my VMs to new cluster and live migrate all VMs. Thing is when I try to join to cluster from old node I get this error: root@home-node-5500:~# pvecm add prox-02.domain.tld...

Hello, I work for multiple clients and one of them wanted us to create a Proxmox cluster to assure them fault tolerance and a good hypervisor that's cost-efficient. It's the first time we put a Proxmox cluster in Production environment for a client. We've only used single node proxmox. Client...

Hi everyone, I'm new here, basically this is my first post on this forum, and I do have an issue with my Proxmox. I do have two proxmox servers in cluster and, I try to add a Windows VM (from NODE1) to a domain, which is on NODE2. Unfortunately, there is no connection, the nodes have connection...

We have a cluster of 25 nodes, all machines are backed up on PBS. The last update to the latest version, on proxmox nodes on which we have VM and LXC, was carried out on 24.11. However, on 3.12 in the morning, a problem appeared with one node. CPU load on one node increased to 100%, it was...
