Dear forum members, I have encountered several questions regarding the operation of High Availability in Proxmox VE and would like to discuss them with you: Why does the pve-ha-crm failover process exceed a processing time of more than 60 seconds, with a significant increase in CPU usage...

Hallo allerseits, ich bin quasi neu hier :). Ich betreibe mein Homelab mit 5 Servern seit Jahren unter ESXi und nun ist endgültig die Zeit gekommen, alles auf Proxmox zu migrieren. Ich habe das Thema Proxmox schon lange auf dem Schirm und mich immer mal wieder informiert, aber so richtig...

Hello everyone, I would like to share some issues I’m facing with a distributed 7-node cluster on Hetzner, hoping to gather suggestions or ideas on how to resolve them. Cluster Configuration: • Nodes: 7, distributed across Germany and Finland. • Purpose: Simplify VM migration and...

TL ; DR - I don't care which host the High Availability VMs move to, as long as it doesn't exceed 4 VMs per host. Can this be done? Full Story - I am planning out a 4 host cluster (and 1 QDevice) of PVE with HA active using CEPH Storage and plan to run 8 Windows Server VMs across all hosts. I...

Hallo, ich würde gerne wissen, wie ich 2 Nodes aus verschiedenen Netzen zu einem Cluster verbinden kann. Ist dies nur über ein VPN möglich, oder gibt es andere einfachere Alternativen? Vielen Dank im Voraus für eure Antworten! ---- Hello, I would like to know how I can connect 2 nodes from...

BACKGROUND I work for a small business that provides a 24 hour service on our servers and requires as close to 100% uptime as possible. Our old IT company sold us 2 identical Dell R420 servers several years ago with a single 6 core processor, 4x 3.5" 600GB 10K SAS HDD in RAID10, and 16GB RAM and...

Hallo, wir haben nun seit einiger Zeit ein Proxmox Cluster am laufen. Wir betreiben 4 Server mit 128 x AMD EPYC 7543 32-Core Processor (2 Sockets), 512GB RAM und Ceph mit insgesamt 16 OSD´s. Bei der Performance von Linux Servern ist alles optimal. Hier haben wir keine Probleme mit...

I have been experiencing an issue with one of the nodes i just joined to my cluster. It was in an old cluster and worked perfectly fine. For some reason in this new cluster i keep getting this issue. I am able to get the error to explain itself when i'm migrating a vm so that's why in the...

Hello all: As I rebuilt my Proxmox cluster from scratch, I attempted to configure ACME certificates for the first time. I had no issues and got all (3) nodes working initially. The following day, I could not log into nodes 2 and 3 via the UI but could via SSH. The only change was that the ACME...

I have bought 3 identical servers, both have a 10gbe network adapter with dual ports. I want the cluster to communicate via the 10gbe network adapter but each individual server via 1gbe port to the router. If one of the nodes fails, i want it to fallback to the next server. So far, i have...

Hi, I'm trying to deploy DR form my lab where currently, I have 3 nodes in location1 with HA and ZFS replication, I would like to add 1 node in location2 which is used for DR incase location1 is down, the HA doesn't have to be automatic, I can turn on the VMs by myself if needed, so far i have...

Hello Proxmox Community, I'm working on a home lab and need to save power, so most of my nodes are powered off most of the time. My goal is to set up a Proxmox cluster that can dynamically scale as nodes are powered on and off without requiring high availability (HA) or strict quorum. I’m fine...

PVE Version 8.2.7 Hello I have been running a PVE cluster of 4 nodes for some time, and started using SDN (VXLan) since even before release. All worked rather stable, but recently one node started having problems. SDN spans between nodes via static IPs, and has a few VNets. Three nodes...

When things work, there are no problems. When things does not work at all, there are no big problems (at least, most of the time...) It is when things work half way that the worst problems happen! Here, I have a cluster made of 2 nodes (latest version) and a remote QDevice. Nodes are PMX-A and...

Hi People, Im having a bit of a weird issue where I have created a striped Logical Volume using the CLI but when I add it to the storage.cfg or use pvesm add lvm <STORAGE_ID> --vgname <VGNAME> to add it to the cluster it shows up as full. Im sure I am doing somthing really silly but I can't...

I have 2 nodes The hardware is the same but I got the second one later. They are both running 8.2.4 in a cluster. I was trying to migrate powered off VM's from the older server to the new. However, the volume groups aren't named the same. On the 2nd server do I need everything to be setup...

Hello, From what I see, the corosync uses max number of cluster nodes+1 as a quorum for the cluster. So in 11 node cluster, 6 is the quorum. This is logically ok, but in real life scenarios, I need to have part or cluster to shutdown, and if shut down part is 5, then one more node and cluster...
