cluster

Hello, I’m currently installing 3 pve hosts in cluster mode with an iSCSI EMC array, everything is redundant : 2 ToR switches for the servers , 2 switches for the iscsi traffic. We’ve chosen this solutions to migrate from ESX (too expensive). I’ve read a few articles / posts related to PVE...

Good day to all, The following scenario: A server with a PFSense, not virtualized, not part of the cluster. A cluster with various nodes. Some of them have only one NIC, some have multiple NICs. The complete As a goal I would like all cluster nodes to have access to a specific lan of the...

Hi, what is the recommended procedure to shutdown a complete PVE cluster including HA resources? The manual only talks about maintenance of single nodes, but sometimes it is necessary to shutdown everything. We have observed that a simple shutdown on all nodes is not sufficient as HA fencing...

Hi everyone, I'm having some performance issues with the Proxmox API on my cluster. As the number of users and virtual machines grows, the API becomes slower and slower to respond. I've already checked that the hardware is top-notch and the servers have enough resources, and I've also checked...

New Proxmox user here. I have a Proxmox Node (call it Node 1) that has numerous hard drive bays and just added another node from an older Optiplex 7010 SFF with 4 cores, 32GB RAM and is very limited on the number of drives I can install (call it Node 2). Currently I have TrueNAS installed on...

Hi! I'm implementing 3-node Proxmox cluster with CEPH storage. Each node has 4Gbit LACP interface (made of 4*1Gbit physical) as a public, and two 10Gbit interfaces for CEPH traffic. Is it a good idea to have Cluster and CEPH traffic both on 10Gbit interface? Or should I use public interface...

Hey yall, my 2 Node Cluster started to do weird things I cant explain - at least for now. All nodes run on the latest 7.3.4 release. Serv1 seems to be offline? It can be pinged, and I can open terminals (even from VMs), view stats etc. It is marked with a question mark from both...

Greetings Yesterday I installed my first Proxmox Backup Server ; I was able to easily add it as Storage to my cluster. However, I can access it only from the node I was connected to when adding the storage ; other nodes see it as "not online (500)". The storage was configured for "all nodes"...

After this forum could already greatly help me with a cluster issue, i now have more of a question than an issue. Ive recently tried to improve my cluster a little and one of the things i did was moving all vms to a shared storage, to make migrations way faster, which works great. Now as i...

Hey. Im running out of ideas on how to re-add a node to my existing cluster. This node was previously part of the cluster, but i had to temporarily use the server elsewhere. Ive reinstalled proxmox but i just cant add it to the cluster (with 2 other nodes) anymore. As far as i can tell the two...

I have 2 proxmox servers (proxmox-1, proxmox-3, both PVE 7.3). After creating a cluster on proxmox-1 and joining it on proxmox-3, I see additional disks on proxmox-3 host in the UI, with the same names as the disks on proxmox-1, but in status "unknown": /etc/pve/storage.cfg on both nodes (looks...

Hi all. I have 2 servers running Proxmox 7.3 standalone and I want to create a cluster with 2 nodes. I have the following schema: - server with hostname proxmox-1 at IP 192.168.88.70 - server with hostname proxmox-2 at IP 192.168.88.80 and they communicate to each other via router and can access...

Ich habe einen Cluster mit 15 Knoten laufen. Der Zugriff auf den Cluster erfolgt über einen HA-Proxy. Alles läuft tadellos. Außer ich will ein Backup oder ein einzelnen File aus dem Backup wieder restoren. Hier bekomme ich einen Fehler. Wenn ich mich ohne HA-Proxy direkt auf einen...

hello, i have a "cluster" of 2 nodes, after renew my certificates i cant access the second node in my webinterface (of proxmox) i see my cluster (two nodes) - but, a click on my second node shows me: tls_process_server_certificate: certificate verify failed (596) how can i "import" the (re)...

Hi Everyone, I have an unusual problem with the ZFS virtual machine block size (zvol). Proxmox version 7.3 I have a configured proxmox cluster consisting of two servers plus a qdevice device. I set up a datastore (ZFS) from the webgui of proxmox called SSD_ZPOOl_1 and set its block size to...

Hello, I'm experiencing a pretty strange connection issue when connected to the second vpn VM (wireguard). I got two proxmox nodes, each do have a VM with wireguard, a VM with a dns server, a VM with traefik proxy, both nodes have the same etc/network/interfaces files. Both wireguard VMs are...

Hello everyone, first time post, sorry if the formatting is wrong. So I started in a company and took over a proxmox cluster on Debian 11. After toying with proxmox for a few months, I decided to check the last thing on my predecessor's to-do list "keep the system up to date". Simple enough...

Regarding the large cluster I spoke about in my previous thread. I spent a solid day on site reinstalling every system and replumbing everything, and got it all running again along with separate individual networks for three clusters of 8-10 nodes each. Yesterday, I started setting up the...

Hi all, i have a 3 node cluster. In my HA section i created a group with all nodes and i added my VMs as resources (in this case VMID 200). If i shutdown the VMID 200 from console/ssh (using "shutdown -h now" or "poweroff") or using "shutdown" from PVE GUI, the VM goes down but after a second HA...

Hi What is the best way to manage two (or more) "independent" PVE servers in the same frontend? I don't need any high availability, automatic failover or shared/synced storage. If one server goes done, then it should have no influence on the others (I should still be able to start/stop VMs...
