cluster

Hi all, We are currently running an outdated PVE cluster (version 6.4) consisting of 5 nodes. All VMs and containers are using an external NFS share for both disk storage and backups, mounted at /mnt/pve/NFS. We’ve recently acquired 2 new nodes, and instead of adding them to the existing...

Hello :) Since 24h I'v been banging my head on a problem that appeared by itself yesterday around 12pm according to the logs. Since yesterday, I can't get my cluster to work properly: I have 3 nodes A, B, C. If I turn on nodes A and B or B and C, everything works fine. As soon as I turn on A and...

Homelab-Umgebung. Ich habe ein Proxmox-Cluster mit 2 Proxmox-Servern aufgezogen, kein dritter Quorum-Client mit dazugehängt. Das Cluster war recht einfach einzurichten: cluster/pm1 (alle Vserver zuerst hier) cluster/pm2 (noch kein Vserver hier) Danach habe ich alle Vserver von pm1 nach pm2...

Hi. Bonehead move #126 of the week. Problem: While playing around with joining clusters (using 2 different pve nodes on different IP), I decided to just 'unjoin' the cluster. It wasn't working right, so I deleted the cluster.conf file in the /etc/pve/ folder. When I did this on node #2 (a test...

I am having an issue getting a pfsense DHCP relay to work across my proxmox cluster. My network is as follows: vmbr0 -> 192.168.12.0/24 - home internet (this is where my proxmox clusters are connected to vmbr1 -> 192.168.2.0/24 - virtual interface connected to a smart switch for VLAN 4...

I am curious about linux-kernel native TCP Multipath (not the proxmox iSCSI multipath-tools approach).Anyone here using MPTCP forcing all PVE nodes to open MPTCP sockets instead of TCP? Tentatively, my homelab with PVE cluster nodes with dual SFP+ 10gb uplinks on the same network could in...

Hi, I have a two node cluster configured, home setup. I have a primary node with all the needed services running. The secondary node is actually empty at the moment and not really needed. I plan on building it up, maybe, and have it available to migrate things as needed. For the time being...

Hi everyone, I'm pretty new to Proxmox, and so far, I really like it. Today, I attempted to connect my two OVH servers to run as a cluster over the private NIC. Everything seemed to work fine until I started experiencing timeouts on the second server through the UI. After some troubleshooting, I...

Hi All! Perhaps I am just missing something here but as a cluster do the smtp certificates not sync between nodes or should I be requesting certs for both nodes? ... or is there something else entirely? Thanks! Kris

Hello all! is it possible to create API token which can be used for access only to one/two node in PVE cluster ? thank you

Hello, I'm a bit of a noob in the proxmox world, I've dived into it quite recently, I'm trying to wrap my head (and having a hard time with everything new) about the optimal architecture for my selfhosted home setup. My (foolish?) objective would be to have a proxmox cluster that would allow me...

Hello, I have a two-node cluster and am setting up a separate PVE datacenter. Since Cluster 1 serves different groups, I want to keep the new datacenter completely separate. I need to migrate a VM from Cluster 1 to the new datacenter. Is this possible? Initially, I considered adding the new...

What are the best storage configurations in Proxmox to access a SAN with multiple nodes while ensuring high performance, redundancy, and simultaneous access? How do options like ZFS over iSCSI, ZFS over NVMe/TCP, Ceph compare in terms of latency, scalability, and complexity? The goal is to...

Hi all! I have a pve cluster and a cef storage of 3 nodes. On one node, both OSDs are in the down and out status. I need to replace this node with another node. I added a new node to the proxmox cluster, installed cef. Tell me what are my next steps? Do I need to delete the OSD on the node I...

Hi, I have three PVE servers running at two separate locations, connected via VPN (two in Germany, one in the UK). They are set up as one cluster - mainly because of the common VM id number space and occasional non-time-critical machine migrations between the sites. We do not want to use HA...

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...
