cluster

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...

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...
