This is part two of my article on getting Unraid 7 up and running on Proxmox on Terramaster F6-424 Max.

See first part here!

Getting Unraid 7 to work on Proxmox:

My Initial passthrough config:

/etc/kernel/cmdline:

  root=ZFS=rpool/ROOT/pve-1 boot=zfs intel_iommu=on iommu=pt pci=noaer

I could probably remove pci=noaer since the BIOS allowed me to turn off Advanced Error Reporting per PCIe channel.

/etc/modules:

  vfio

  vfio_iommu_type1

  vfio_pci

  vfio_virqfd

/etc/modprobe.d/i915.conf

  options i915 enable_fbc=1 enable_guc=3

/etc/modprobe.d/pve-blacklist.conf

  blacklist pcspkr

Unraid VM-config:
  General:

    Name, Id

    OS:

    Do not use CD-ROM

  System:

    Machine=q35, BIOS=OVMF, Qemu Agent=X

  Disks:

    Your own preferences, But Im going for 1T, Discard=X, SSD emulation=X

  CPU:

    8 cores, Type=Host

  Memory

    16384, balloon=0

Then add Unraid USB, iGPU and ASM1166 SATA controller to the VM.
After that...Hit Start.
...and nothing happens. Bummer!
Ok. Lets kill the vm

 

Drop to shell on your Proxmox-host and run

rm /var/lock/qemu-server/lock-<YOUR-VM-ID>.conf

qm stop <YOUR-VM-ID>

To get things going, we need to isolate the iGPU and SATA-controller.

lspci -nn

00:02.0 VGA compatible controller [0300]: Intel Corporation Alder Lake-UP3 GT2 [Iris Xe Graphics] [8086:46a8] (rev 0c)

04:00.0 SATA controller [0106]: ASMedia Technology Inc. ASM1166 Serial ATA Controller [1b21:1166] (rev 02)

OK, so its 8086:46a8 and 1b21:1166 we want
Run

echo "options vfio-pci ids=8086:46a8,1b21:1166" > /etc/modprobe.d/vfio.conf

echo "blacklist ahci" >> /etc/modprobe.d/pve-blacklist.conf

echo "blacklist i915" >> /etc/modprobe.d/pve-blacklist.conf

echo "blacklist xe" >> /etc/modprobe.d/pve-blacklist.conf

update-initramfs -u -k all

reboot

Now try to start Unraid VM...Success for you as well, I hope.

Well, not all went well...
Im getting errors in Unraid dmesg regarding the GPU, but everything (eg hw-transcoding in Plex and Emby, Frigate detection etc.) seems to work just fine.

And after shutting Unraid VM down and restart it, the SATA-disks does not show up in Unraid. The isolation of the SATA-controller works...I dont see any SATA-disks in Proxmox. Only after a powerdown/restart of the Proxmox host, disk are visible again. For now Im passing through the disks instead of the controller. This I cant solve.

Edit after 2w: So...the backup solution was to passthrough the disks instead. I know Unraid wants full control over the disks, but I have now been running with all my disks passed through, and so far no problems.

So, all in all, I'm very happy with the setup. It works very well, and I must say that for the price of the MAX, you got plenty of power to play with.
I really recommends this piece of hardware, even though I'm still disapointed with the SATA-passthrough debacle.

UPDATE:

 

It works perfectly to passthrough ASM1166 to Unraid or any other host. I have enabled all ASPM-stuff in BIOS.
The culprit is "powertop --auto-tune" settings. Again. See my post about this here.

If you really wants to run this(on the F6-424 Max however, it does not really make a difference in power consumption) you have two alternatives:
1. Isolate the ASM1166 on the host.

echo "options vfio-pci ids=1b21:1166" > /etc/modprobe.d/isolate-sata.conf
echo "blacklist ahci" >> /etc/modprobe.d/pve-blacklist.conf
update-initramfs -u

2. Skip the isolation steps, and run all commands produced by "powertop --auto-tune" instead, but excluding the ASM1166 part
Below is the commands --auto-tune would have runned on my system(with 1 nic disabled)
You can create a list for your own system with 

powertop -C powertop.csv && cat powertop.csv

echo '0' > '/proc/sys/kernel/nmi_watchdog'
echo '1500' > '/proc/sys/vm/dirty_writeback_centisecs'
echo 'auto' > '/sys/bus/usb/devices/1-3/power/control'
echo 'auto' > '/sys/bus/pci/devices/0000:00:14.2/power/control'
echo 'auto' > '/sys/bus/pci/devices/0000:03:00.0/power/control'
echo 'auto' > '/sys/block/sda/device/power/control'
echo 'auto' > '/sys/bus/pci/devices/0000:00:1f.0/power/control'
echo 'auto' > '/sys/bus/pci/devices/0000:02:00.0/power/control'
echo 'auto' > '/sys/bus/pci/devices/0000:00:04.0/power/control' < This is the ASM1166
echo 'auto' > '/sys/bus/pci/devices/0000:01:00.0/power/control'
echo 'auto' > '/sys/bus/pci/devices/0000:00:1f.5/power/control'
echo 'auto' > '/sys/bus/pci/devices/0000:00:00.0/power/control'

Run all commands above EXCEPT:

echo 'auto' > '/sys/bus/pci/devices/0000:00:04.0/power/control'
