cluster

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...

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...
