You can use cpufreq-info to see which driver is currently used.

You might be missing something here. You have to distinguish between the intel_cpufreq driver and the intel_pstate driver. As seen below, you seem to use intel_cpufreq. For this driver, your claim is valid. This governor actually sets the CPU to the lowest frequency. I was talking about the...

Ich habe ein ähnliches Problem. Einer der Server im Cluster ist tot (Hardware-Fehler). Ich will den jetzt ersetzen, dabei würde ich gerne die IP und den Hostname des alten Servers verwenden. Wie gehe ich da am besten vor? Es müssen keine Daten, außer der IP, vom alten Server übernommen werden...

I think the package is called linux-cpupower in debian. Also the solution posted by H4R0 is quite easy and works well. For servers I want to be able to script the settings, which works well with cpufrequtils. I do not see the advantage of using cpupower apart from having nice dialogs...

Stimmt, da habe ich vielleicht zu kompliziert gedacht. Ein Vzdump Backup reicht natürlich völlig. Aber gibt es Anbieter bei denen ich sowas leicht machen kann? Ich will ja nicht jedes mal aus einem Disk-Backup (wie es quasi jeder Hoster anbietet) mir eine VM erstellen müssen.

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...

Thanks for your answer. I finally came around to try this and in the end it worked. It saved me several hours compared to the "traditional" approach of backup, delete, join cluster and restore. It took a while because I was still testing the new cluster. Then Proxmox 7 came along and I upgraded...

I believe I had the same or a similar error. Server with two NICs, the "I219-V" (eno1) is used for VMs with VLANs. When the VMs started the connection to proxmox was lost. Accessing via the other nic worked fine. The network of the VMs worked fine. Just the proxmox host could no longer use this...

Do I understad you correctly that you have - 2 Servers which are mostly turned off - 1 big/important server - 1 normal server In this situation you could add a QDevice as aaron suggested. This is probably the best solution. You could also change the voting power. For example you could give...

Funny, I wanted to ask nearly the same question. I am planning on replacing an SSD from a healthy zfs-mirror, since it is getting close to be worn out. I am planning on adding the new SSD ... resilvering ... at that point it would be a 3-way mirror ... and then removing the old SSD.

This will only work for identical nodes. Having nodes with different hardware causes different packages to be installed and therefore different updates. Thanks, I did not know about "forks 1". Apart from that, I would still prefer if PVE supported updates somehow better. Especially for kernel...

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...

Sorry, I have no AMD servers with Proxmox/Linux right now. But PVE is based on Ubuntu. Most things that work for ubuntu also work for PVE. Do a search for amd power-management in ubuntu or amd cpu scaling in ubuntu or amd battery life ubuntu. Usually you will find something where people talk...

The % display of CPU load might be wrong when the CPU is scaling its frequency down. When running on anything other than "performance" you should look at the temperature and power-consumption (~ voltage). I use netdata for this, but you can choose any tool since netdata might be a litte overkill.

Yes, for automated tasks spinning down might cause timeouts. My old NAS (without PVE) is also used for backups. I have a pre-backup script which tries to access a certain file (therefore spinning the disks up) and only after it can access it, the normal backup continues. This is also a nice...

There are also Boards like the ASRock J4125M which has 3x PCIe 2.0 x1. While I agree that PCIe x1 is rather slow, it is fast enough for a RAID/HBA controller or a dual channel GBit NIC. Yes, the disks would benefit from a faster connection, but PCIe x1 is fast enough to saturate my 1 GBit home...

I had the same "issue" that the hardware changed. But the MAC stayed the same, therefore DHCP worked as expected.

You can attach the NVMe drives with a PCIe to NVME Adapter. Some BIOS might have a problem to boot of these, but most do boot. The save way is: one PCIe slot for one NVME; used this many times without problems. There are also adapters which fit two NVMEs to one PCIe slot. This might not work...

I am not sure if the "replace the intel-pstate CPU power management driver with the acpi-cpufreq one" part is still valid for recent CPUs. What I have done is simply set the powersave state and let the CPU do the rest. echo "powersave" | tee...
