cluster

Hello. So I've gone through what I think are the docs regarding PROXMOX and fibre channel presented LUN's. I'm using an older 3PAR 7200 in my lab, attempting to get shared storage between a PROXMOX cluster. So far, I have a fully operational cluster with a shared NFS volume, which performs...

Hi all, I’m a little confused on how I would achieve this goal..... I’ve been tasked with migrating over our existing PFSense VSrv & setting up HA in the event a server fails or VM fails. I have setup a Proxmox cluster [ 2xDell R630 as PMS & 1xDell 3040Wyse running debian as a QDevice to...

We are planning to add a new hypervisor to our cluster. Three existing nodes have an AMD EPYC 7352 CPU and now we are unsure if we should go with the latest EPYC 9XXX processor or if we should stick with EPYC 7352 for the new server. I have already tested the migration from EPYC 7352 to Ryzen 9...

Hi there, On our PMG Cluster, we have 1 node that rejects all mail for one of our users. Here is a NDR: node1 said reject: RCPT from smtp2.e.amses.net[213.161.89.103]: 550 5.1.1 <nigel@example.co.uk>: Recipient address rejected: undeliverable address: unknown user: "nigel"...

Hello Support, I have a cluster made up of two nodes and I would need to migrate the cluster nodes to a new VLAN (changing the IP addressing) How can I do? Do you have a guided/recommended procedure to follow? Is there a service interruption? Thanks

Hi everyone! I currently have a 3 node cluster in which node 1-2 is physical servers and the 3rd one is a vm running on unRAID. (proxmox: v8.1.4 [16GB of RAM, 2 HDDs in RAID1 using ZFS, i3-4150 in both node1-2], unRAID: 6.12.4 [16GB of 48GB, 4 cores of a 6 core i5-8400, 2 vm disks on different...

Dears, I run 2 PVE nodes in a cluster for hobby/learning. I login with PVE auth, root user on PAM is disabled for login. Now when I log into the shell of one of the nodes (as root), I'm immediately logged out if I leave the shell (for example: clicking on another item of the datacenter GUI)...

Hi, to set the context, I want to connect my ceph cluster to my proxmox cluster, I did the same thing as leihnix Post reference: the https://forum.proxmox.com/threads/using-external-ceph-cluster.93453/ I also see that my pool is visible with a question mark but the size is not available, do you...

I have just set up a three node cluster, extending my single host setup. pve1 = 172.x.x.10 pve2 = 172.x.x.20 pve3 = 172.x.x.30 Each node can ping the others fine. From pve2 and pve3 I can ssh to pve2 pve3 and pve1 fine. Nmap also shows all ports open. All nodes use a vlan ID of 5. My issue...

I recently set up a cluster between two small PVE nodes in my homelab to provide failover on critical VMs. I was doing this in a bit of a sandbox for testing, and today I learned that if the failover node isn't turned on when you restart the primary node, none of the VMs on the primary node will...

I have 2 networks in my server management and HA. I am creating a cluster which one should I use?

I have a server (HPE Proliant ML350 Gen 9) with 2x E5-2667 v3 and 128GB ram. I want to build a cluster and see a HPE Proliant ML350 Gen 9 with 2x E5-2687W v3 and 256GB ram Can this be clustered together (i know i still need a 3d one). My current server has 2x Samsung PM893 2.5" 1920 GB SATA...

I have started to use SDN network and it's work with VMs. I have created a cluster and I've added a new node. In this node SDN network is pending "local sdn network configuration is not yet generated, please reload" and /etc/network/interfaces.d/ is empty. Do I need copy files manually? All...

Hi there. I'm having problems with online migration of VMs between two hosts in a cluster. Both have local storages (lvm thin). If I try to start the migration via the GUI or without options from the command line, I consistently get the following error: 2024-01-24 12:35:10 starting migration...

Hi Forum, i have setup a 2 node cluster configuration to keep the configuration in sync. As it seems, the added acme account from node1 was copied to node2. I was able to request a certificate for node1 without a problem, but on node2 i experience this behaviour: i can only select the...

Good afternoon! I am facing a challenge with a cluster hosted on OVH consisting of 5 servers, each with a public IP. The cluster is working fine with IPv6, but I have identified some vulnerabilities, such as public communication between servers, the absence of a private network, and direct...

There's a great deal of misleading piece of argument to be found in currently official PVE docs on QDevices [1] and then some conscious effort to take it even further. Under "Supported setups" [1] the following is advised (emphasis mine): It continues to provide an absurd piece of reasoning...

I will preface this by saying I am a total ProxMox/CEHP noob... I am good with Linux and I have been a VMware Admin/Engineer for the better part of 2 decades... I have looked through dozens of walk-thoughts and videos but I am still struggling with CEPH and I need some help. Goal: HA...

Hello I would like to share an information for other sysadmins who may face the same problem. I was unable to add a new node (pmox5) to my cluster from CLI, I always get error "500 Can't connect to <cluster_master_ip>:8006 (hostname verification failed)" : root@pmox5:/var/log# pvecm add...

Hello guys I just got a 2U 4 node box and I want to use this for my proxmox. In VMware there is no issue to have more than 3. I just wonder if this is the same here. I notice many YT all demo that into 3 nodes cluster. Thanks.
