Hi everyone,

As the title says, I'm new to Proxmox and wanted to play with it as a weekend project.

First, this is the hardware I run:
Ryzen 3 3200
ASRock B450 Pro4 v2.0
16GB RAM
Proxmox (7.3.1 version) runs on a SATA enterprise SSD plugged directly to one of the sata port on the mobo
MSI RTX 3060TI
LSI SAS9211-8 in IT mode with a mini-sas to sata cable running 3 x 8TB Enterprise HGST hard disks

Proxmox installation went fine. I enabled IOMMU and VT-D (whatever is the AMD equivalent) in the motherboard BIOS and updated GRUB accordingly for AMD.
I installed a VM and it boots without problem but as soon as I try to boot the VM with my LSI card passed-through as a PCI device, the all system freezes and I have to hard reboot it.

This is what the shell output looks like when it happens:

[ 274.518805] Buffer I/D error on device dm-1, logical block 22480892
[ 275.186413] Buffer I/O error on device dm-1, logical block 13905

I also tried passing the LSI card without the 3 HDs but same issue.

Googled around but cannot find any solution.
Any help would be greatly appreciated.

Happy to provide any logs or any information needed.

Thank you

Your LSI-card is most likely in the big chipset IOMMU group, and you cannot share devices from the same group between VMs and/or the Proxmox host. Except for the X570 chipset, Ryzen system can only passthrough the first x16 PCIe slot (or two x8x8 in X470/X370) and the first M.2 slot (x4 PCIe) connected to the CPU. As soon as you start your VM with passthrough, all other devices in the same group (network, USB and SATA controllers) are no longer accessible by the Proxmox host and it crashes.

Thanks for your reply. Here's the output from that command. Looks like my LSI card shares group with other devices which cause the crash:

Thanks for your reply. That makes a lot of sense.
 
It looks like you're encountering a problem with your storage device. The error messages indicate that there are issues with the data being written to and read from the device, specifically "Buffer I/D error" and "Buffer I/O error". This could be caused by a faulty cable, a problem with the hard disks, or even an issue with the LSI SAS9211-8 itself.

It's worth noting that the LSI SAS9211-8 is a hardware-level RAID controller, which means it is designed to manage multiple hard disks as a single storage device. In order to pass it through to a VM, you will need to disable the RAID functionality on the controller, as this is not supported in a virtualized environment.

Based on the error messages you provided, it seems like there may be a problem with the hard disks or the controller itself. It's worth trying to update the firmware on the controller and also replacing the cable to see if that resolves the issue. Additionally, you can try connecting the hard disks directly to the motherboard to see if the issue persists without the LSI SAS9211-8 in the mix. This will help you narrow down the source of the problem.

You cannot share devices from the same IOMMU group between VMs and/or the Proxmox host.

Thanks for your reply.

The LSI is in IT mode so no longer a RAID card per se. The HDs and cable were tested right before I put together that setup so I know they're fine. The IOMMU group sharing seems to be the issue here. Thanks for the link you provided, will take a look at it.
 
So I went with the added pcie_acs_override=downstream,multifunction option and that made the trick.

Thank you all for the help. Much appreciated.
