I want to use Proxmox at two different locations. My question is how can I connect them to each other? We already have small PVE cluster at our office. This is ideal for development and testing but not suited to serve the public (internet connection to slow, not enough IPs, etc.). The plan is...

I am having some problems with one of my VMs. The dmesg is full of "Out of puff!" errors while the host never got close to running out of memory. Any idea why this happens? [Mi Mär 15 01:10:59 2023] kworker/2:0: page allocation failure: order:0...

I have been using PVE for some years and I want to also use PBS now. It seems like I don't quite get some of the concepts. My setup is: one PVE cluster and one PBS on a separate physical machine. The PBS has 1 SSD as boot drive (with zfs) and a raid-z2 array of 6 HDDs for storage (called...

I am using netdata to monitor my PVE hosts. On some of them I am getting inbound_packets_dropped_ratio warnings because 2 % of packets are dropped. Any idea why? Here is my setup: Each host has 2 NICs, first is mapped to vmbr0, second to vmbr1. vmbr1 is only used for PVE traffic. It is...

Hallo, ich setze in einem eher kleineren mittelständischen Unternehmen Proxmox für die in-house IT ein. Nun sollen ein paar IT Dienste/Funktionen auch für Kunden angeboten werden. Derzeit entwickeln/testen wir das in einem LXC Container mit Debian 11 auf unserem kleinen Proxmox-Cluster. Wenn es...

I have an Ubuntu 18.04 LTS VM running on PVE 7 which I assigned 32 GB of RAM and enabled ballooning. The VM does batch-processing and is using > 20 GB RAM for a few minutes, after which it goes back to use close to none (less then 500 MB); that's why ballooning is enabled. The strage part is...

I have a stupid question: Is rebooting a PVE node from console (i.e., typing reboot) the ideantical operation as clicking reboot in the GUI? Until now, I only ever restarted nodes from the GUI,. This does a clean ACPI/agent "shutdown" to all VMs, while obeying the shutdown-order and timeout...

I have installed apticron in order to be notified of available updates. While this works well, I get an e-mail for each node in the cluster. Only one mail would be better. The next question is: is there a good/recommended way to manage package updates in a cluster? I think it is quite risky to...

I have a single PVE node which has a few VMs and CT. I want to add it to an existing cluster. I know I could backup all VMs, remove them and reload from backup. But this is very time consumming. Is there another way to do it without moving so much data around? The IDs do NOT overlap between...

I have a proxmox cluster where each node has two tiers of storage: fast and small (=SSD or NVME) named "localSSD" and slow and large (=HDD) named "localHDD". Everything is ZFS. The VMs running are not HA configured. They can go down for some time, but preferably not hours/days. Each VM has a...

I want to set up a new Proxmox server which will be mainly used for a Windows VM. Proxmox will be installed on normal SSDs. These SSDs will also be used for other VMs. The main VM will be a Windows Database Server which should use NVMe drives. I have 2 PCIe x16 Slots and want to use them for 2...

What happens if I overcomit RAM? Lets assume a Server with 64 GB RAM. Let us "reserve" 32 GB for proxmox+ZFS. This leaves 32 GB for VMs. What will happen if I put 10 Windows 10 VMs, each with 2 GB min and 8 GB max RAM on it? With Guest Agent and Balooning installed. Obviously, this will use...

I am using Proxmox on typical servers with multiple drive bays. The disks show up on the GUI as sda, sdb, ... which is not very helpfull identifing a disk. I would like them to show up named after their respective drive bay, eg. bay-1, bay-3, ... . This woule make thins like replacing a broken...

Which filesystem shoud I choose for a Linux guest? I am running various Linux guests on Proxmox 6 with a ZFS Storage. The storage is usually configured as either mirror or raidz2, both with compression "on". The guest storage is usually set to SCSI on VirtIO SCSI controller with "discard"...

The NAS which is used by my proxmox as a backup datastorage had a problem. The problem led to the nas being very unresponsive/hanging. It looks like this behaviour also influenced pvestatd is such a way that it has became a zombie process. dmesg shows the following errors. I can say for sure...

I am a little confused about how to setup a small proxmox cluster. My goal is to have 3-4 nodes in a cluster. I do not want to use Ceph nor GlusterFS. Obviously, also no HA or live migration. I do want to use replication though. The goal is in case of failures to recover within hours (not days)...

I just installed a clean proxmox 6.0 on a machine and the network card does no longer function properly. It worked with Proxmox 5.4 Hardware: HP server with 2x gigabit on-board card + HP NC364T PCIe (4x gigabit card, with 2x Intel 82571EB chips). The problem is, that 2 of the 4 ports get...

I am new to proxmox and want to understand it better. A node shows me the "IO delay" value. What is IO delay? How is it calculated? Knowing this would make it easy to answer questions like: what IO delay is acceptable? Is 5% a high value or is 50% acceptable? etc. I tried searching the...
