also, when using PCIe ssds, one sacrifices a PCIe slot. Slots that could be used for GPU pass through. What I failed to mention is that I would like to have a dedicated VM to pass GPU's to so that I can donate to the folding at home or other distributed science projects

I am not trying to be a d*&k but if the mentality remains that proxmox is not for non server workloads then perhaps installing a windows (yeah I know it's evil) machine and go from there with virtualbox? I'd rather prevent that route as I have spend more than a year getting to know proxmox and...

ok understood now. So ZFS, although I said it was not a requirement, then now it is. Never I intended to suggest that ZFS was off limits. Sorry for the confusion. That particular document I have read indeed. I also did not find much regarding NVMe's. I did see an Intel Optane on the top of the...

or with 256 GB of ECC memory. perhaps load an entire VM in ramfs? that would mean that loading a VM is no longer fast but for one or two specific VM's that would be no problem

for example do I use the AORUS Gen4 AIC Adaptor (1 PCI device for 4 x NVMe SSD) with 4 x WD black SSD's in raid0 mode? Or put them in the 4 xNVMe slots of the mobo and then see if I can raid 0 them?

understood. Important data on a VM goes to a TrueNas. The VM it self gets backed up to TrueNas. So I can always roll back to a previous snapshot if need be. wow, I am now considering your drives. Is there any benchmark I can see? All I found and use was something along the lines of...

I'd like to setup proxmox 7 to be as fast as it can possibly be with the hardware I have and that I am considering to get; EDIT: (this will be for non critical, non server related workloads) Edit 2: I would like to have a dedicated VM to pass GPU's to so that I can donate to the folding at home...

the keyboard was usb added using vendor id. so changing port does not matter it will always be passed through. Anyway I luily found a spare keyboard and got it sorted.

During a non scheduled network change I lost the ability to connect to the PVE GUI. But because one of my VM's, with keyboard and mouse passthrough, has autostart I can also no longer log into the host CLI. Yeah I know, rookie mistake this configureation :( How can I get into the CLI? It's ok...

can one please expand on smtp relay part of the first answer? how to do that?

i think it is dmesg. because when looking at; https://unix.stackexchange.com/questions/641021/identifying-physical-memory-slots-from-dmesg-ecc-error-outputs shows an output similar to the one I saw on the pve host monitor

Not entirely sure what log one sees when looking at the monitor connected to the pve host. That is one of the places one can confirm. Can you please have a look at; https://serverfault.com/questions/643542/how-do-i-get-notified-of-ecc-errors-in-linux ? one of the comments mentions 'Running...

I have a motherboard, CPU and memory on where single bit ECC detection, correction and reporting and multi bit detection and reporting is confirmed to be working. what would be the most straightforward way to recieve an email when ever the OS receives an ECC report?

Could you please elaborate on the tweaking you did? I am getting abysmal results on 2 x Samsung SSD 980 PRO zfs mirrored using default zfs settings during proxmox installation. Used PVE < 6.4 for installation and currently fully upgraded to most recent version. pve-manager/6.4-4/337d6701...

just found myself in a similar situation trying to passthrough a evga rtx 2080 TI to a win2k19 vm. I have done it before on a asus prima x570-p mobo so I know it can work but now on this gigabyte trx-40 mobo I am getting the 43 error in windows. Does anyone have an update on this please?

Thank you @gomu , @developers is there anything down the roadmap to level the functionality of @jeanlau his workflow between nodes?

But in theory having the uppermost part of a zfs pool referted should not be messy? What in practicse shouls i watch out for?

thank you for your more detailed analysis. Why can't one simply snapshot the root/rpool?

I am checking it out sooner or later

@wolfgang , I would very much would like to second @cserem 's request
