  1. I am searching for thunderbolt 3 support recently in the forums and found most of the answers are "No", except this case: The poster used a thunderbolt 2 enclosure for the drives and it is working properly with unraid release before (except the booting issue he addressed). Wondering if anybody tried any thunderbolt 3 external drive enclosure with TB3 device (e.g. intel NUC) actually? I found the following information in egpu.io: since in unraid 6.5.2 we are already at Linux Kernel 4.14, and should include the following patch for TB3 security control: https://lkml.org/lkml/2017/5/26/432 does it mean unraid support eGPU already by: $sudo sh -c 'echo 1 > /sys/bus/thunderbolt/devices/0-1/authorized' like this topic: https://egpu.io/forums/pc-setup/egpu-in-linux-has-anyone-here-gotten-it-to-work/ does anyone ever test it?

    Thunderbolt 3 eGPU support

    since in unraid 6.5.2 we are already at Linux Kernel 4.14, and should include the following patch for TB3 security control: https://lkml.org/lkml/2017/5/26/432 does it mean unraid support eGPU already by: $sudo sh -c 'echo 1 > /sys/bus/thunderbolt/devices/0-1/authorized' like this topic: https://egpu.io/forums/pc-setup/egpu-in-linux-has-anyone-here-gotten-it-to-work/ does anyone ever test it?
  3. When I switch from Windows VM to another Windows VM, it could happen, let's say once in ten times or 15 times. When the issue happening, usually you just cannot boot the VM and of course you didn't see any output in the monitor as well. (if I use the vbios I might be able to see the UEFI BIOS logo, haven't tried it yet). The worst case, is that the fan of the graphic card is running to its max speed all the time, even after restart the unraid machine. I couldn't boot any VM as the card is not in the system device even. The only way to recover is to shutdown the tower and boot it up again. This occurs, not seldom, but also not often as well. When I switch from Windows VM to macOS, just like switch from Windows to Windows above, usually it is fine. But there is no way to switch back to Windows VM anymore. With vbios I could see the UEFI BIOS logo then, the monitor starts to display some color blocks, very similar like if you overclocked too much for the GPU memory. Then the boot is stuck. However, it is totally not a problem, if I switch from macOS VM to another macOS VM or I start up the same macOS VM again.
  4. tried vbios file, which helps me to get the boot order screen before booting macOS, quite nice, but it doesn't resolve the problem for switching back to Windows. uses the vbios file for Windows VM as well. Once used macOS then switch back to Windows VM. I can see the UEFI bios logo, then the screen output become a mess afterwards. still have to reboot the machine to let the graphic card works again.
  5. Yesterday I made little progress with it. I added AppleALC and Lilu kext files into clover EFI partition, which fixed my RX480/580 recognition problem (previously R9 xxx, now RX580 4GB) and also the performance benchmark is back to normal. Now if I shut down the macOS and start up a Windows VM, there is no more one CPU looping 100% but looks more normal start up behavior, however, GPU still doesn't send the display any output yet. I am feeling this is a kind of hackintosh problem instead of KVM itself...
  6. Hello I see others have issue in old release (6.2.4) that macOS is only able to boot once: But this is not my case. I can boot other macOS VMs after shutting down macOS VM. The only issue is that I cannot boot any Windows VM anymore (with the same graphic card), unless I reboot the unRAID server... This should be related to the graphic cards, because it is totally not a problem if I don't passthru the GPU but use VNC to access macOS.

    HW transcoding

    Thanks! I also found out if I choose AUTO in the BIOS, then iGPU is not loaded at all by unRAID, it seems just ignore it. I have to choose CPU GPU option to let it recognized by unRAID.

    HW transcoding

    I have an AMD RX480/580 gpu (passthru-ed) and 4790K iGPU. If I want to use hardware transcode in plex docker, does it mean I have to enable iGPU and leave it to unRAID itself and not pass it thru to any VM, right?
  9. Hello, I am on unRAID 6.5.0 and use it for sometime without any big issue. Last week I followed @gridrunner's spaceinvader guide and set up the macOS high sierra virtual machines which work perfectly with my RX480/580 passthrough as well . After a couple of days I found out one problem, which is a bit annoying: I am using the single GPU (Sapphire RX480/580 4GB) to passthru to all my VMs since I am not using them together. The cards works well both on Windows 10 VMs and macOS VMs. However I do notice that as soon as the card has been passed thru to the macOS virtual machines once, I am not able to boot Windows virtual machines with the same card anymore (after shutting down macOS VM). The Windows VM just couldn't boot, and one CPU is looping with 100% usage all the time. Instead, it is not a problem to boot another macOS VM (after shutting down macOS VM) with the same graphic card. It seems like the macOS VM did something to the graphic card and it doesn't like Windows anymore... The workaround is simple, I just need to reboot the unRAID. As I am the only user for the server so it is not a problem for me at this moment, just annoying. Does anybody has the similar issue? I am thinking to get another dedicate graphic card to macOS to resolve the issue if your guys have the same problem as well... supplement: macOS version: 10.13.3 Best Regards, Alex
  10. hello there, i am using the unraid server (6.4rc-15e, 4790K/Z97/32GB) and passing through my amd rx480/580 gpu, use it for about 2 months now. recently just notice that my rx480/580 memory clocks often locks at lowest state, which is 300MHz all the time since the windows starts. of course it impacts the performance, especially for gaming. it's easy to find it out. just run gpu-z and start rendering test and check if memory clock jumps up. i have a workaround, to use cru-1.3.1 to soft reset the display driver then the memory clock is back to normal, that means when gpu has workload, its memory clock up to 1750MHz. but it seems i didn't have the issue before. yes, of course I updated the graphic driver to the latest recently but I never get the issue in the physical machine running on the windows 10. does anybody have the same issue? Best Regards, alex

    Use of the cache disk

    I think you can assign 128GB NVMe SSD to cache disk too, just change the Btrfs to single mode. So this leverage the different size of SSDs.

    Parity Check Errors

    ok. I think I will stop here. A couple of errors sound still okay for me. As seen the NPT issue has been resolved on Ryzen build, next year maybe try AMD platform. Thanks a lot anyway!

    Parity Check Errors

    Hello, I ran memtest for more than 35 hours and got no error a couple of days ago. Today I re-run the parity check still found 40 errors. Any other clue? BTW, I am thinking if still needed to have parity drive if I always got errors? If now I have a drive got failed, is it possible to recover the data by the parity drive? Best Regards, Alex

    Parity Check Errors

    ok. thanks. I will double check the memory to see if any finding.

    Parity Check Errors

    Thanks for the quick reply. However I am a bit lost that why I have to run memtest? BTW, in the boot menu of unRAID I have run memtest before, it may take about 40mins and over without any error. How could I let it run for 24 hours? Best Regards, Alex
