Crash / unresponsive every 2-3 weeks
Hi,
I have installed proxmox on a mini PC to run Home Assistant (VM) and other servers in LXC (MariadB, InfluxDB, Grafana, Nore-red) and learning a bit more every day. All is working fine except for three system crashes that it happened about 17 days after last reboot.
Any guidance to help me identify the cause(s) would be great.

Proxmox LXC: Extreme I/O Delays mit neueren WD SA500 SSD
Hi Leute, ich schreibe euch mal in der Hoffnung ein paar Lösungen und Ideen zu meinem merkwürdigen Problem zu finden. Kurz: ich habe 2 Server, auf dem einem Performancen die SSDs ohne Probleme, auf dem anderen Server habe ich mit wirklich hohem i/o Delay zu kämpfen, obwohl auf beiden, die selbe Anwendung läuft, und sie sonst auch identisch aufgesetzt sind.
Von vorne weg, mir ist klar, das Consumer SSDs wie die SA500 nicht unbedingt ideal für ZFS Systeme sind, jedoch geht es mir hier nicht...

It's released today and it brings with it a lot of good features:
- RAIDZ Expansion (#15022): Add new devices to an existing RAIDZ pool, increasing storage capacity without downtime.
- Fast Dedup (#15896): A major performance upgrade to the original OpenZFS deduplication functionality.
- Direct IO (#10018): Allows bypassing the ARC for reads/writes, improving performance in scenarios like NVMe devices where caching may hinder efficiency.

Einrichtung LSI/Avago/Broadcom Matrix Storage Manager
Guten Morgen zusammen,
ich hoffe auf Hilfe zur Einrichtung des Matrix Storage Managers auf einem Proxmox-Server zur Verwaltung von Broadcom-Raidcontrollern. Mein Ziel ist, von einem WIndows-Client, auf dem der MSM als Verwaltungskonsole installiert ist, auf die Controller des Servers zugreifen zu können. Zwischen unterschiedlichen Windows-Systemen funktioiniert das bei mir bereits.

NVME Drive Serial "unknown"

Can PBS backup Hyper-v vms?
Hi All
I was hoping that someone has tried this or has some sort of solution to backup hyper-v vms using PBS?
They VM's are hosted on a Hyper-v server.
We are primarily using Proxmox as our VE.
We are running our windows DC's and other windows services on hyper-v
And was hoping that there is a way for PBS to manage the backups cause the windows native one it terrible.
Then I can set this up for my PVE as well.

PCI Passthrough with RTX 4060 Ti: kvm: vfio: Unable to power on device, stuck in D3
Hey guys,
we do a PCI Passthrough of a TRX 4060 TI on a B650D4U-2L2T/BCM mainboard with an AMD Ryzen 9 7900X CPU.
I got the passthrough working yesterday once after a CMOS reset followed by reapplying these bios options (I verified working passthrough using nvidia-smi in the VM), but after powering off the server and putting it back into the rack, it doesn't work anymore. Every time I start the VM, it does show this error (rebooted ~5 times to test if it occurs every time):

Update & Risk Management Best Practices? How to ensure real HA between Clusters
Hey guys,
today in one of our standup meetings we thought about improving out update strategy. Currently we run multiple clusters running on different versions of Proxmox. So far, to ensure we have our HA services always running, we update one cluster at a time, let it run to ensure its stable and roughly a month later its counterpart.
We do have development clusters in place to test the most recent Proxmox changes but we can never assure the exact software version on each cluster we...

Disabling conntrack on VM interface (with nftables-based firewall enabled)
Hey everyone,
I've got a VM running a site to site VPN which is a backup to a physical connection handled by a hardware router. As a result of this, the traffic passing via the internal interface may be asymmetrical, or existing connections created over the physical backhaul connection may at any time need to shift to the VPN. As one might expect, conntrack is a major issue for these kinds of scenarios, and will happily destroy your connections as a result.
Previously, I've used a...

Truenas as VM question
Hello,
I have a truenas scale VM with harddisks (PCIE) passthrough shared via NFS on all proxmox cluster nodes.
I also have other VMs using that truenas shared NFS storage as their main harddisk storage, the issue is when or if the truenas VM restarts, all other VMs using that shared NFS storage will have IO errors, the only solution is to restart those VMs after the truenas VM has become healthy.
Is there any solution to restore those VMs back to normal state if the truenas VM is...

Ceph rbd mirror force promote
Hello everyone,
I’m currently setting up my first Ceph mirror configuration and have a few questions regarding its behavior.
For example, I’m uncertain about how to force-promote an image on my DR cluster (site-b) during the synchronization process.
From what I’ve read in the documentation, in a disaster scenario occurring during synchronization, a force-promote operation promotes the last snapshot received by the DR cluster. However, as noted:

I added own certificate to my PVE. as I did some times before.
But this time I can not start the GUI again.
The PVE is still running, the VNs are still runing. I can log in the VMs via ssl and I can login to PVE host as root via SSL.

What to do?
