Hi user19.. Is the testlab near you? I would go there and have a look how (and whether) they are connected! Proxmox is "just Debian", which is "just Linux". There is no magic in Proxmox preventing any device being visible.

For reference, the term I could not recall just before I see on screen now: IOMMU group. There is a nice website that lets you look up your board when you don't have access to your Proxmox, or someone else's IOMMU groups ;-)

Hi Daze, Welcome to the forums! Yes, a vague idea :-P Which motherboard do you use? Not all motherboards support a lot of choice in "passthrough groups". I never used it, so the specific terms slip my mind. The point is: you can pass through a resource group all-or-nothing. Besedes that, I...

Is it a direct connection from one building to the other, or is it fiber optic via the Internet? I think @spirit means: a direct cable from one building to the other, only for Proxmox node communication (so not via the Internet, and not shared with other services). What are the ping response...

Hi Albert, Welcome to the forums! For the rest of the story it does not matter so much, but I wondered which HDD and which server, recalling that you already had HDD and server connected to begin with. This is what I understood from your plight: A server (A) crashed thoroughly enough not to...

Hi José, No need to apologize, most of us here are learning :-) The best way to learn may be education, but doing is a good second. Asking someone to solve the problem without having a look yourself takes away the chance to learn. Pay special attention to spirit's message: I think he solved...

Hi spirit, Thanks for chiming in! I wondered about that, but could not find it in the docs (and did not know what to search for). How could you recognize the problem, is it the retries on the messages or the sync/membership changes like the snippet below? Is the timeout configurable, or...

Hi nexi, Welcome to the forums! That is a strange problem you have there. But no question and very little info to go by ;-) Proxmox runs on Debian, which runs on Linux. The initial ramdisk is started before the actual Linux kernel runs, and is not Proxmox specific. I tell this, because you...

The forum is for help you, not to do your work! ;-) Did you have a look at the files yourself? What is your conclusion?

Hi José, That woul maked power difficulties extremely far fetched Yes, there is. Proxmox is built on Debian. Do you have experience troubleshooting Linux systems? It seems there are network problems, but I would learn something new if that turned out to be causing the synchronous reboot...

Hi user 19... But you can access them in Proxmox 7.4 or another OS? There is a way to find out of course... Is the testserver in a datacenter near you?

Hi generalproxyuser, Does the Proxmox-installer have a text mode? Does it suffer the same symptoms? It may not solve the problem with the graphical install, but at least you can get going. Another workaround would be of course to install 7.4 and then upgrade. As for the cause of the...

Hi José, What I notice: All three servers reboot at the same moment, Nov 01 10:39:33 There are many cpg_send_message retry's, which does not seem the way it should ] A processor failed, forming new configuration: token timed out (3650ms), waiting 4380ms for consensus. ; more than 4 seconds is...

That may be, but the 1x PNY Nvidia Quadro P200 is not there just as "smart heating", is it? :p

I got a 4-port Quadro in my workstation. The benefit I have of four screens hardly outweighs the amount X-restarts, Plasma freezes and kernel crashes. It's my first nVidia card in years, having stayed with manufacturers that do provide proper open source drivers. I had not imagined the state to...

The forum is full of knowledgeable people that like to help, but there is some learning curve. Your Proxmox comes with high grade (in my opinion) documentation, but the documentation does not start at "zero". The overview is on the first page of the administration guide at...

Hi José, Welcome to the forums! My first reaction would be: troubleshoot! What are the circumstances under which the servers reboot? Do they restart all three at the same time, or one time the one and then another day the other? Which causes have you checked and excluded? How long have the...

These two entries seem to match the first disk in your "Disks" screenshot, don't they? So, yes, there are contents in the "Storage" tab, but they are the new storage locations, on your new disk. You'll have to match the "Disks" info with what you remember of the contents, to create entries in...

Hi Dominik, Thank you once more for your patient and in-depth explanation, it makes total sense!

Thanks!
