I have an ASRock J5040-ITX as homelab with PVE. Works fine, has only SSDs attached, it is therefore completely silent. At the moment I have one 16 GB RAM module, so I can upgrade later if necessary. This has 4x SATA: 2x are attached to CPU (SSD for Proxmox is here) and 2x with an own...

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 also try to understand the relationship between NUMA hosts and VMs. Let's have a practical example: Dual-CPU Server with 8 cores / 16 threads each, resulting in 32 cores shown in Proxmox. And let's assume 128 GB RAM divided in 64 GB for each CPU. What would be the best settings for different...

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...

Would you be so kind to elaborate on what kind of problems might occur. The problems if a quorum <=50% of votes is allowed are obvious (e.g. split brain) - I would not touch that. But what can go wrong when the votes per node are changed? I have a 4 node cluster, which by default would need 3...

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...

Thx for the reply. I will probably go with a traditional zfs raid1 and hope the performance is good enough. Having to do dd+config altering for a migration is way to painful.

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...

Makes sense to cause such a high CPU Load if its polled at that frequency. The question is: why on earth such a high polling rate? Even for gaming this is, most of the time, to much. Why not the very common 125 Hz? Also, can the polling rate be changed? Using the mouse without "tablet mode" is...

I experienced the same. A question out of curiosity: what exactly does this option do? Is there any Difference if its on or off if I only access the VM via SSH or RDP and never by using the proxmox VNC?

Seems to me like a job for the Agent. Would be really nice to have an option where qm suspend would flush the cache from within the guest. Obviously, this should not be the default.

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...

This would obviously be a great idea. As far as I know, smartmontools can not do this. There are specialized tools for that (check out this: https://serverfault.com/questions/64239/physically-identify-the-failed-hard-drive ). The overall problem seems to be, that the mechanisms used to control...

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...

I also updated the drive database, but I am still getting these errors. Any other ideas?

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"...

Oh sorry, I forgot to mention that I use CIFS/SMB to access the NAS. It was configured via the GUI, therefore it uses the default settings imposed by the GUI.

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...

Is there already a bug report for this which I could follow? I plan to set up the server in a way that if the UPS looses power the server waits for 5min for the power to come back and then it suspends all VMs and shuts down. Gracefully shutting down all VMs might take way to long, especially...

It would make sense in a home-server environment. There, the server does not need to run 24/7. I do the same with my backup NAS. It just WoL it, do Backups and it goes to sleep by itself 1 hour after the last connection was terminated.
