Hi,
Very interested in unRAID, next to the storage part I want to run a VM on there that runs home-assistant. So I need to use my Zwave USB stick in that VM. Is it possible to forward a USB device to a VM?
Yes you can forward USB devices to a VM.
Some people forward a complete USB host controller for maximum functionality, but in most situatuations it will work well to just forward individual devices.

Well some of us do have some long memories...
Although, if you look at the past year, you guys are kicking butt and taking names! I have thought multiple times recently, “dang it, I just updated and there’s another update!!”Yes, the update speed have been way higher the last year. And lots of the changes have been very useful for a larger group of users.

Have you measured this yourself? I actually don't notice a difference when it comes to mouse/keyboard input speed between using USB assignment vs. USB controller pass through.
You should normally not be able to notice with keyboard/mouse. A traditional keyboard/mouse has a quite slow report rate - maybe 125 Hz report rate. It's only gaming keyboards/mouses that make use of 1kHz report rate. And we humans aren't fast enough to measure such short delays. But when the game responds to key presses or mouse clicks synchronized with the display frame rate, then one in x mouse clicks may result in the game responding one display redraw earlier which for 100 frames/second could scale a 1ms mouse lag into a 10ms slower game response.
Where it normally matters for non-gamers is when using USB sound cards, JTAG-interfaces, logic analyzers etc that streams synchronous data that may require hard real time (a bit depending on buffer capacity on each side). But for this type of devices, I have - in some situations - clearly seen a difference between having the VM own the USB host or just bridging the USB device. But it matters what other hardware shares the interrupts on the host machine and what load the host machine has (and quality of drivers), so it can work very well even with streaming devices. But a single slow critical section in the kernel can starve the USB processing enough to affect the transfer.

I've added the 250GB drives as UD drives in a RAID0 configuration
Did you need the extra transfer speed? RAID-0 means you lose all data if one drive fails.

As you have noted, I have seen more reports in these forums of Seagate drive failures than any other brand, yet, Backblaze rates them highly.
Backblaze also see failed Seagate drives. But they note that they buy the Seagate drives cheaper than WD Red drives. And since their infrastructure can handle broken disks, it's more profitable with the Seagate disks. If 5 disks in 100 fails, that still only represents 5% of the purchase cost - and if they buy the drives 15% cheaper than WD Red and the WD drives maybe have 3 disks in 100 fail then it's clearly an advantage to select Seagate drives.
For normal home users, it doesn't work well to consider amortized costs like that - we don't have the same routines to maintain redundancy even with multiple broken disks. And we don't have the same routines to restore data to new disks. And we have so few disks, that a single broken disk will represent a significant percentage of the total purchase price of the storage server disks.

You do have to be careful with screen grabs if they are in .jpg format. I know that with the previous BB that they were scaled down in size when inserted inline in the text portion of the message. (I was uploading 'Banner' headings for the GUI and they were being scaled about 50%.) IF this is still true, what you see may not be what the original poster saw...
But the poster of the bitmap can at least spot if the bitmap doesn't look the same as the text output. When I look at the bitmap from my monitor, it looks the same as the text above/below. But I intentionally cropped down the width to reduce the probability of the forum scaling it in the inline view.

@ars92 I noticed those speech bubbles that have replaced the bullet (thread that contains unread messages) and the star (thread to which you have contributed that contains unread messages). But which style of speech bubble icon means which and how am I supposed to remember? I suppose they look prettier but they are less functional.
Bullet and star = easy
Two slightly different speech bubbles = difficult
Filled speech bubbles means you have been busy filling it.
Empty speech bubbles means the thread is waiting for you to fill it with good content.
Grayed speech bubbles means no new content.

Agreed. That's why I specified 1:1 pixel mapping and a non-Retina display. When looking at the samples you also have to make sure that they are being viewed at 100%.
Viewing at 1:1 is obviously important. But the DPI decides how many 1:1 pixels that are used to render a 12point font, since the point system relates to an inch - there are 72 pica points in an inch and when rendering to printer or display, the computer needs to figure out how many pixels the output medium fits in an inch.
Viewing that bitmap at 1:1 on a different monitor with a different DPI will show the characters larger or smaller than on the original system, since the pixel sizes will differ. Apple have been using the term Retina for a rather large span of DPI - from about 220 DPI to 460 DPI. Lots of Windows installations are also using quite arbitrary DPI settings, i.e. Windows isn't configured to match the true DPI of the monitor - that's a common trick to force rendered information to be larger or smaller.

It definitely looks way better than all the screenshots shown here
Note that the look of the screenshots doesn't just depend on system and web browser, but also on what DPI the display is configured for. So a screen shot from a QHD or 4k monitor isn't likely to look similar to a screen shot from a monitor with lower DPI. And lots of mobile phones are configured to run with quite low DPI (to preserve the battery) even if the native display is high-resolution.

but you probably should use unraid.local instead
With the forum having moved to unraid.net, it's definitely best to stay away from own DNS entries of type x.unraid.net, since you can't know what subdomains Limes may introduce. so x.unraid.local would definitely be a better choice, given that .local is a reserved name for broadcast-local network trees.

I've also got an extended test running but that'll take a while.
Extended SMART tests aren't really good friends with disk rebuilds.
Both the rebuild and the extended SMART test requires access to all of the disk surface.

...huh. That worked. Why did that work? I don't remember having any issues in earlier versions of unRAID and I've been running uBlock Origin for forever.
Anyway, thanks so much for the quick reply.
A newer layout may have introduced some changes in the block structure or tag labels that trigs the ad blocker. Ad blockers hae manual white- and blacklist options just because they can never be 100% correct - they will sometimes misunderstand content.

better getting this clarified while you have a working system.
I would also be quite worried that the old flash drive might have been added to the blacklist, blocking any future updates.
And it's quite important that Limes checks the error codes to get the key management server aligned with any other changes introduced during the domain name move.

So what do you suppose my browsers are doing? The text I'm seeing is clearly Nudista - it just isn't being rendered properly. If it just substituted Helvetica that would be an improvement.
I'll try unchecking that box in Firefox.
I'm quite good with HTML but leaves the true CSS magic to professionals. I know what the CSS constructs does, but doesn't have the professional knowledge about what goofs different web browsers suffers from and what workarounds that are needed. My speciality is in systems-level coding, electronics and interfacing directly with the hardware. So quite far from web front-end work.

There are quite a lot of 404 links right now, especially if searching on Google.
But the bug reports subforum link should probably get some priority. -

I also just viewed the forum on Edge and I don't see a noticeable difference between it and Firefox or Chrome.
When the web designers knows what they are doing, then you shouldn't see much difference between browsers unless the user have decided to explicitly tweak their browser. I'm still curious why the typekit download doesn't work for some users.

There's no USB 3.0 port in the server, so hardly a point to getting anything 3.0 anyway. 🙂 I think I'll grab the 16 gig kingston and see how we do.
It's just that lots of stores are starting to focus on selling USB 3.0 devices since the cost difference is low. But besides giving more boot problems depending on motherboard etc, USB 3.0 devices tends to be very hot so they cook the flash memory. Every 10°C warmer flash memory means the retention time for the data is halved. So a 20°C warmer flash memory has only one fourth the retention time. And unRAID doesn't constantly write to the flash so the content isn't regularly getting refreshed.

I'm just trying to protect my data from the average (stupid) burglar.
Most people don't need to worry about more than a normal burglar - or about being able to send in a drive for warranty replacement even when the drive interface is dead so the content can't be overwritten.
But it's always good to notify people about potential limitations. Lots of uses have heard about AES-256 and thinks AES-128 is too unsafe to use - and then use a 20-30 bit password to unlock their 256-bit encryption key (assuming that each character of English text is worth about 3-4 bits of security).And lots of users wants "extra high" security so they use key files representing maybe a million bits of security (regarding the randomnes of the file contents) to unlock a 128-bit AES even when nothing they do can make the system safer than the 128-bit AES key. And then they follow up by forgetting that their server only has 100k files and an attacker can ignore the amount of noise in the "key" photo and just try the 100k files one-by-one. Or read the configuration file that names the key file and the host that stores the key file.
Hopefully the new web site can result in people stepping in and reworking the FAQ texts.

I was just going of the image on the guide page really. Kingston recommended? https://www.computersalg.dk/i/887769/kingston-datatraveler-se9-usb
Most USB 2 drives from Kingston and Sandisk should work well. Just with a slight warning for drives with tiny form factor. And a big warning for USB 3 devices.
I have one system with a datatraveler - I think it's a SE9. It has worked well for maybe 5 years. (But I have seen people have issues with SE9 G2 that is USB 3)
I also have a system with a Sandisk Cruzer Blade - also maybe 5 years of perfect function.

Would this be a viable option: https://www.computersalg.dk/i/610267/sandisk-cruzer-fit-usb-flashdrive ?
At least some Cruzer Fit drives runs quite hot because of the small size. But the USB 2 variantes are at least cooler than the USB 3 variants. Unless you are worried that someone will bump into the drive, it might be better to go for a full-size thumb drive.

I stand corrected, pwm.
You should go ahead and own the wikipedia entry; https://en.wikipedia.org/wiki/Remote_Desktop_Protocol
"Microsoft requires third-party implementations to license the relevant RDP patents.[40] As of February 2014, the extent to which open-source clients meet this requirement remains unknown."
Just note that Microsoft has a number of patents you can license for free. So even when patents are involved, you don't always need to pay anything. And this is possible for both commercial and open-source products. But Microsoft has managed to make the situation so complicated that they have to recommend users to contact them for formal answers:
https://msdn.microsoft.com/en-us/openspecifications/dn750984
"please contact the IP Licensing Team"
The problem comes from RDP involving multiple patents where an RDP client doesn't need coverage of all - and it isn't obvious which patents are needed.
You have one patent for handling of user state of remote desktops in a cloud.
And another patent for secure sessions.
A third for handling transparency in a remote desktop.
A fourth for double-buffering when doing remote desktop sharing.
...
Different RDP clients may have different patent needs, and Microsoft needs to help out with which patents are relating to the Patent Promises program and which patents are not. And that is probably also why the wikipedia page can't know the actual state for different clients.

It seems I hit UnRAID in the middle of a transition period.. I was using this guide; https://lime-technology.com/getting-started/ which contains a link to recommended USB devices, but it resolves to a 404 page on the new domain instead.
I'd really prefer migrating the config to a new USB device.. as the one I am using now is fairly ancient and - as I mentioned - of an unknown make/model. I'd rather shell out for a supported quality drive since this server is fairly important to me. Anyone got a short-list? Even the wiki reference 404's: https://wiki.unraid.net/UnRAID_6/Getting_Started (I did try searching for it on the main site.
)
Alas quite a lot of 404 links right now to unraid.net. Just hours since this forum moved from a limes technology domain name to unraid.net. So I bet the admins has lots of work to do to catch 404 requests and apply redirects.

I just assumed he was using RDP in Windows, not from unix. There are plenty of unix options, I doubt they're licensed by Microsoft most of the time though.
I don't think you need to pay for the use of RDP. It's part of the Open Specifications and I think any patents might also fall under the Patent Promises program. But anyone wanting to make a commercial RDP client should obviously contact Microsoft to make sure.
Here is a free RDP client for Windows:

And I think this one is also free:

Security Benefits of Gaming in a VM
in Unraid Blog and Uncast Show Discussion
Posted
Gamers really are worried about input lag for mouse/keyboard. And it can be shown that every x mouse clicks will be delayed another display redraw even for a single 1ms delay of the click. But since this requires statistical methods, it shouldn't matter much for most users who aren't using real-time-streaming devices.
Besides using statistical methods, the lag can't be seen. Standard keyboards/mice have 125 Hz poll rate just because we aren't fast enough to notice the delay even when the key presses are only polled every 8 ms. But with 100 fps, a 128 Hz poll rate means half the key presses will be delayed one additional display refresh and in some games that will be measurable in damage-per-second or similar.
