unRaid can do that.
The advantages of going unRaid are that you already know the OS, so the learning curve will be reduced. And you know how friendly and helpful the community can be, if you get stuck
Going with something else such as Proxmox or other will also work for you, and you have the opportunity/challenge to learn a new system.
If it were me, I'd go with unRaid, mostly because I'd be too lazy to learning something else, and it will just work, mostly. 'Better the devil you know'

Maybe a path in a docker or VM that is not correct ?
Yes, I'll need to trudge through all my settings. I'd find it odd though, that a docker could actually create a share like that.

Bah! Fix common problems to the rescue.
it seems I now have both a ‘media’ share and a ‘Media’ share, and that’s the root cause. I have zero idea how that happened though. Will need to conduct some further investigations as I have not created any new shares in quite some time.

Hi folks
Stumped by this one. I've seen several similar threads in search, but none of the solutions seem relevant.
Today, a significant quantity of files and folders have gone missing from my shares, in particular, my 'media' share (all my movies & music etc.).
The files still exist on the disks, just no longer showing in shares.
I have no apparent disk issues - all are present and green.
I have checked share and global share settings, and no disks are excluded.
I have run XFS check on all my array disks with no errors reported.
I cannot be 100 percent certain, but I believe most/all of the missing files are located on Disk1.
Diagnostics attached. What am I missing???

Perhaps you can disable docker? This would allow you to either adjust your unRaid network settings so they don't conflict, or delete the docker image (and force a reinstall) which will give you a window to reconfigure or remove Shinobi.
There's a thread here that has info on how someone else did this (for a different reason;

Have you taken the time to edit your vm xml to ensure both the video and audio nodes of your gpu are set to the same virtual bus and slot? UnRAID borks this and can cause to problems like you are experiencing.
have a look at the link in my sig for details on this and other things to try.
-
The behaviour sounds like a situation where the GPUs have been reserved. In this scenario, the boot sequence shows up to a point, but appears to stall.
Have you a clean unraid install, or have you ever set any VFIO reservations for passthrough? (if you have, and the n shifted or added devices, the assignments can change and th wrong devices can become reserved).

Thanks!
Would it be okay when you give the OS 2-4 thread and would there be any negatives in the file transfer speed with going to low?That should be fine. I believe the recommendations are to give unRaid at least core 0, and alway include core 0 as there is some benefit in that (i'm not sure what).
Remember, the above guidance is specifically around isolating cores for high performance VMs such as gaming. If you have a few dokers that are not computationally intensive, you can pin non-isolated cores to them, leaving a bit of headroom for unRaid to take as needed.
Also, you don't need to isolate ALL the cores assigned to a VM. You can, say, assign 4x threads to a VM, but only isolate 2 of them. The VM then has two dedicated threads form its exclusive use and two others that may or may not have other tasks assigned.
There's also a TON of esoteric analysis on here about performance benefits of assigning specific threads / cores to VMs based on how the CPU is constructed etc. Its as bit over my head, but some peeps seem to have eeked out a bit more horsepower by paying close attention to how core assignment is managed. based on CPU architecture.

If you switch on the help in the GUI on the isolation page, you will find this;
QuoteCPU isolation allows the user to specify CPU cores that are to be explicitly reserved for assignment (to VMs or Docker containers).
This is incredibly important for gaming VMs to run smoothly because even if you manually pin your Docker containers to not overlap with your gaming VM, the host OS can still utilize those same cores as the guest VM needs for things like returning responses for the webGui, running a parity check, btrfs operations, etc.
So, when you pin a core to a VM or Docker, that core is allocated to the VM/Docker, but the unRAID OS may still access it and use it for various tasks.
When you isolate a core, it is no longer accessible even by unRaid for routine tasks and should therefore be 100% dedicated to wherever it's pinned.
You can pin cores without requiring a system restart. You must restart your unRaid server to effect any isolation changes.

Nice. Perfect!

As the multi-lingual aspects get more popular, the activity feed is filling up with incomprehensible posts.
Is there a way to add a filter to remove certain forums / languages from the feed?

So as someone who's just finishing up a trial, it looks like I missed all the pain. For me, it was a very straightforward initial setup ad the update was smoothness itself.
The 1.8 UI, on first impressions, looks like a vast improvement on what went before which was somewhat clunky and tricky to navigate (on desktop).
Now, my only decision is Qobuz or Tidal. (I'm leaning towards the former).

One step forward, I got the gpu to show up in device manager but it has the -43 code
I'll try to get rid of it later...
That’s progress. Section 8 in my blog post suggests a solution for -43 that’s worked well for me.
-
Check the link in my sig to see if there are any tips there that you might have missed.
one trick that works well for me is to install virt manager docker, and use that to add a VNC graphics device alongside your gpu passthrough. In the vm xml , double check to ensure that the vnc adapter is first (before the gpu).
then, when you boot the vm, you can observe the boot process via VNc to see what’s foing on.
ive had instances in the past where the vm was stalling or jumping into seabios, of where windows was loading into recovery or waiting at the login screen.
its always a good idea to use netplwiz on windows vms to set up auto-login, it eliminates on other potential trip hazard.

Since you precleared them before shucking, are they still recognised as precleared when you connect them directly to SATA ports? The reason I ask is because WD used to use encryption on some of their external drives (around the time when 4 TB was considered high capacity). The encryption was performed by the USB to SATA bridge chip so shucking the drive made its contents unreadable. Not a problem for Unraid purposes - just clear it again after shucking. I wondered if that was still the case.
I still haven't found the time to shuck and, more to the point, disassemble the server to drop in the drives. I'm waiting on another part to arrive (caught up in Christmas/Brexit shipping fiasco) so once that's here, I'll do so and report back.
The pre-celaring was not so much to preclear as to run the drives at some degree of intensity while still in their cases to see if there would be any issues that would merit a warranty return. (none showed up). Also, these will be parity, and I can't recall if parity disks actually need a pre-clear
Anyway, will report back once I get a chance to do the installation.

Hi
I cannot help with the specific issue, but I have a few pointers that might be of general assistance....
First, try to ascertain if it's the bonding, the dockers or a combination of both that's causing your problem. Run with one and not the other for a while, then swap. This will help a lot with narrowing down where the issue is.
Second to help with retrieving logs on reboot......;
Saving log files is not on by default.
Go to Settings -> Syslog Server and switch the 'mirror syslog to flash' setting to 'Yes'
You'll then be able to see the previous syslog when you reboot. A few notes from the help;
This setting is NO by default and must be used with care to avoid unnecessary wear and tear of the USB device.
Change this setting to YES when troubleshooting is required and it is not possible to get the regular diagnostics information. A mirror of the syslog file is stored in the logs folder of the flash device.
-
3 days to preclear in their cases. I'll be shucking in the next few days
-
Well, they are presently preclearing. I've kept them in their cases and connected via USB 3.0 but it's a slow process. Averaging 160MB/s and getting slower as the pre-read reaches the edge;
If they keep going at this pace, and no problems arise, I'll have them ready for shucking by the new year!
-
From what I've read, I don't believe these particular units even need those workarounds. Mine arrived on Saturday, but I'm running it through some stress tests and will do a preclear or two before shucking to ensure they are OK OOB. So i wont be able to tell what drives or power config they have for a few more days.
@juan11perez, here's a decent video on how to get the drives out, you can see its fairly straight forward, and they are just regular 3.5"drives inside;

Just bought a pair of these to replace dual parity
Good value when when compared to smaller sizes on offer for higher prices.

Has anyone ever tried using anything like this https://www.walmart.com/ip/PCI-E-Express-3-Port-1X-Multiplier-Riser-Card-Mining-Cable/269154426
PCI-E Express 3 Port 1X Multiplier Riser Card?
My computer only has one port free (besides the GPU port) for MacOS and I would like to put in a fenvi T919 for macOS PC PCI Wifi Card Continuity Handoff BCM94360CD Native Airport WiFi BT 4.0 1750Mbps 5GHz/2.4GHz MIMO 802.11ac Beamforming+ WLAN PCI-E Card in addition to the USB controller card I'm already passing through.
How do these multiplier cards pull off sharing just one PCIe lane?
All of the expansion cards in the entire machine I want to use are just are 1x
My system should be in the signature (Dell Optiplex 9020)
Hi @Jagadguru
Yes. I use these with great success. See here;

and here;

You can even assign cards in each slot to different VMs as they can show up in different IOMMU groups.
They work using a technology known as PLX. Essentially, theres a traffic cop chip on them that assigns each slot on the expander board a slice of time on the motherboard slot. In effect, this is transparent and the system sees cards populated in the expander as discrete and additional devices. I've encountered no problems using up to 4x USB 3.0 cards in these expansion devices, all assigned to different VMs simultaneously.

I came to the same conclusion on this as you did. The price and availability of working 4 port cards is kind of wonky so rolling your own has some advantages.
I use a 4 port mining riser which I bought for ~$15, they're pretty easy to find all over. I seem to have better luck with ones using the asmedia chipset which is what most of them use.
Advantages are easier to find and flexibility. You can mix and match devices (including SATA controllers and different types of USB controllers, even video cards). Also you can install 4 port cards instead of needing to use USB hubs, most 4 controller cards only give you one port per controller.
Disadvantages are if you're buying all the controller cards from scratch its not much cheaper than the all in one card and it takes up a lot of space and creates a wiring mess. So you'll need a custom case or a case with a lot of expansion slots in many cases. And when using USB 3.0 you have a bandwidth bottleneck. I've never seen an (affordable) mining riser that doees 4x pcie to 4qty 1x pcie splits, they're all 1x to 4qty 1x pcie split. The bottleneck doesn't really matter to me since I really only use USB 2.0 and 1.1 devices.
Yes, a 4x -> 4 1x would be useful, however given the way the PLX chips work, it just slices the time each card gets in the slot so it would likely be a different hardware solution in that case.
This is the one I'm currently using. It's really compact and I can mount it anywhere in my case, running I/O brackets to the back panel if necessary. That way, you only take up the number of precious expansion slots you actually need, rather than all 4 (or 8 in the case of the lorger expanders designed for dual width GPUs).

Well I fail to see any use case for a desktop OS without a video card..
I have a windows vm running blue iris for Security camera duties. No video card.
i also use this as a whole house audio server with multiple legacy m-audio delta multi-channel sound cards. No Linux drivers, but works fine on windows or Mac OS. No video card required.
this also runs windows-only tv tuner software for whole house DVR, no video card required.
i also have this connected to an old alarm system for which I wrote some drivers. The vm manages the connectivity and interfaces with a node red docker where all the logic is implemented. No video card required on desktop os for this job either.
there are loads of use cases for desktop vms with no gpu. Of course, a lot can be handled in other ways on Linux, for example, but for those not comfortable in the black arts of bash and the command line, a headless windows or Mac vm can be a great tool.
