  1. leave drive spun down

    Quite right. Unmounting the file system does indeed require a write to the disk. And part of unmounting is flushing any write buffers to the disk. The disk has to be spinning to do these activities. It is possible that by spinning up the drives serially before the stop array request is made, the intensity of the power spike could be reduced. (When a drive is spinning up it will pull more power than keeping one spinning.) You could do the spinups manually or with a simple script. But it could also be that the way the array stop works, the disks are spun up serially anyway. Not 100% sure. What is the concern? Power usage? Or stress on the PSU? I don't think either should be of much concern.
  2. Thanks @stewartwb! Gotta love this Windows 10 world where beta code can land our your hard disk with no warning. I just looking in my Credentials Manager and don't see what I would need to delete if I was hit with this problem. See screenshot below. Can you indicate what you saw and what you did. (BTW - no idea what that generic credential is, but did a search and evidently it is normal).
  3. Value motherboard w/ IPMI?

    I had an ASRock Server MB (E3C224-4L for Haswell Xeon) with IPMI and VGA. Worked great. Traded it in on a ASRock Workstation MB (C226M WS) with an extra x4 slot which i really needed, but lacking the IPMI and onboard Video. Good trade for me. Had slight issue with the C226M and USB passthrough, and resolved it by disabling USB 3.0. Not a big deal for me, and probably should reach out to tech support to report the issue and maybe get a BIOS fix. Its an old board and not sure they would. I really don't miss the IPMI. The ability to do a remote reboot was certainly a nice convenience, but only used it once or twice, as rebooting my server remotely is not a common need. Most of the time when I am powering up the server, it is after doing some work on the machine. And I want to be standing there switching it on in case of any clicking or fireworks! TBH, I prefer very basic VGA video on the MB to IPMI. But both are nice. I think its harder to find boards with the right number of slots and lanes and memory expansion. In today's world, I'd want 8 memory slots, ability to handle 2 PCIe 3.0 x8+ (double wide for video cards), 1 x8 PCIe 3.0 (single wide for HBA), 1 x4 PCIe 2.0+ (RAID card I need), and 1+ x1+ card (USB card / other if needed) - none blocked by the video cards. I'd also want 3 USB 2.0 controllers (one for unRAID and 2 to passthrough for keyboard/mouse). If it had all that, I'd be fine with no video or IPMI. My prior MB was a SuperMicro - got super deal on it but limited on memory. I don't generally like the way the way SM boards are outfitted - lanes and memory expansion often limited or not meeting my requirements. For whatever reason, the ASRocks usually are a better fit. I would not hesitate to buy either if it met my needs.
  4. I am running 1703. Not sure when 1709 is coming. I have had similar problems with DNS name being recognized, and added my unRAID server and IP to my "hosts" file a while back. That cleared up my problems at the time. Might try that. If the IP address has changed, there is caching that occurs (separately for browser and Windows). I've had cases where the browser would not open my unRAID server by IP, but that I was able to open a putty session in Windows. Google can help you with methods of clearing these two DNS caches. And also time will take care of it. Watching this with interest. Please keep us updated!
  5. I am doing parity checks every 2-3 months. Always do one before and after any disk / hardware activity. Between parity checks, I do md5 verification runs, which serve a similar purpose to parity check, but they check for file corruption instead of parity corruption.
  6. storage transfer question

    Issue I was asking about was he appears to have a 1T vdisk on each of his spinners that would need to be reduced in size to fit on a 256G SSD. I remember one of your videos explained how to reorg the data and truncate the disk size, just don't remember which one. I agree no parity on a disk holding VM images.
  7. Can you be more specific on the issue you are seeing? What do you mean "until Windows loads the GPU drivers"? Are you saying that the passthrough doesn't seem to start as soon as it should, but that once Windows drivers load, it works fine?
  8. @gridrunner may have other ideas. Reduction in gaming performance from >60 to 26 FPS is not typical.
  9. Setting up VM for remote workstation

    You might look at NoMachine and SplashTop as alternatives for RDP.
  10. Actually unRaid "array" requirement can be met with 1 hard disk - or even 1 USB thumbdrive. 20G would give 8G to each VM, and 4G to unRAID. I can't say that is enough. Depends on games. If you know Windows with 8G is sufficient for games, I'd suggest 8G from unRAID to be sure. So 24G. One SSD should be enough. So long as enough space for both Windows images. I'd suggest probably 250G or 500G. Or duals is fine too.
  11. I am not a gamer, but this is not typical of VM slowdowns I have read about. I'd expect reductions of maybe 20% or so. So there might still be something not quite right in your config. If this is the sole video card, you might try the ROM file in the XML. Could also be that you are not giving enough cores or memory. Or not allocating matching cores and matching hyper-thread cores properly. Review carefully and experiment and you might find something that could pump up the video performance.
  12. You would need two video cards which I'm not thinking your micro ATX is going to support. 8G RAM is not enough, probably need 20G minimum (8G each for VMs + 4 for unRaid). Although I'd recommend 32G+. 4 cores (only 3 available for VMs) is not optimal. I'm far from a gaming rig expert, but think if you want a serous 2 in 1 gaming rig, you're unfortunately going to be doing major upgrades. 6 or 8 cores, bigger motherboard able to support 2 x8 PCIe 3.0 video cards, good cooling, beefy PSU. If the goal is much more modest, you might squeeze a video card into an x1 slot and run games in lower res settings and get something running. I still think 8G would not be enough.
  13. Any issues in this SMART report?

    The smart report looks ok. Only thing that is a little concerning is the multi zone error attribute with a raw value of 22. I've seen multi zone errors cause strange symptoms on the past, but usually see them in combination with other issues. Part on hours are on the high side.
  14. Help me choose. . .

    I'd suggest getting the 3 8T. Replace parity and parity2. With other 8T, replace 2T+2T+3T=7T. So you'd have 1T free. You now have 2 empty slots. Buy 8T drives to fill those as needed. Use the 4T drives as backups or spares. This should keep you a while. If any of your 4T are showing their age (near 5 years power-on hours) or have SMART issues, I'd look to swap them out 2 for 1 with 8T. Recommend the best buy easystore 8T externals, which are easy to open and extract WD Red inside. Cheap and good option. HGST 8Ts are more expensive, but are an even better quality option IMO. But with a big price difference, I'd probably be leaning towards the harvested Reds.
  15. Intel Coffee Lake (8.gen)

    Interesting the Coffee Lakes do NOT come with HSF.
