[Unable to open /dev/net/tun, is tun module loaded?: No such file or directory (solved)]

So I'm attaching a diagnostic, but in fact the problem went away with a reboot.

 

Thanks Squid.

 

I didn't realize just how huge and bloated my logs are...

[Unable to open /dev/net/tun, is tun module loaded?: No such file or directory (solved)]

I'm running into this all of a sudden... Was there ever a solution? I've found two specific references in the forums but no replies...

[Ability to clone VM's]

Even just the ability to clone the configuration and give it a new name... I do this routinely when I'm resurrecting a clients dead drive. I plug it into my USB or Drive Bay (Hot Swap) and boot the machine up with a standard configuration and attach the physical drive to the VM

[NVME Raid Pass Through to VM]

I currently have a Samsung 980 Pro that I pass directly through to my Gaming VM

 

I picked up a second 980 Pro (I haven't opened it yet) and wanted to add it to my system and use Intel Enhanced RST to run the two drives in a stripped raid passed through to the VM.

 

I tried it first using my 980 Pro and an Intel 600P. I don't expect good results from this mismatched pair, but I wasn't expecting what I got.

 

I created the Array in BIOS and it made a slightly larger drive than the 1TB drive, but when I boot into Unraid I don't see the drive at all... 

 

Has anyone tried this? got it to work at all?

 

Thanks

[Keep certain VM's running without array started]

I run pfsense in a VM and there are definitely times that I would find it usefull to take down the array without having to lose my router. Currently it's located on the cache but I would move it to the NVMe drive in an instant if this would work.

 

I don't do it often, but there are times I seem to have to do it many times over a few days.

[VM GUI Update]

I went looking for this request... I use a VM with a bootable CD/iso to perform disk task on client hard drive and would like to be able to more easily mount a unassigned drive and select the boot drive. Right now I have to go in and make changes to the xml Every Time.

 

I love that this workflow is even possible, but would really like to see it performed more cleanly.

[[Plugin] CoreFreq]

Having Done a little further experimentation... The behavior I'm seeing is EXACTLY right... I was thinking along the frequencies that intel lists for this chip, but not realizing those are SINGLE core boost frequencies.

 

I'm seeing ALL cores hit 4.8Ghz until the package temp hits 80 degrees and then they back off (4.6 or so) until it stays below 80. 

 

Thanks

[Dynamix - System Temp]

Is there any way to change the display at the bottom of the GUI to either ALWAYS diplay the decimal point or to NEVER display it? The constant shuffling of the line at the bottom back and forth is disconcerting.

 

[[Plugin] CoreFreq]

I assumed it would... I've built this system around an air cooled quiet solution.

 

I'm in the industry but I really haven't built a computer other than my servers (built and rebuilt really) since the AMD Athlon. I've been using Laptops for about 20 years.

 

Maybe I just watch too many Linus videos.

 

I'm really just screwing around with the new build on the principle that I have the skills and the equipment so lets lap the IHS and Heatsink to try to get a TINY gain and slow my cooling system down even more.

 

No real reason. Just practicing arcane skills. The whole rig is meticulously cable managed and there is not a window in sight.

 

Thanks

[[Plugin] CoreFreq]

For reasons of my own insanity, I want to get temperature readings on me server before and after I make soe risky and likely pointless modifications.

 

I looked and looked for some way to stress test the CPU and get a temperature reading. Eventually realizing I may have that already in this plugin.

 

Is there a way, or does it already, keep ap log of the results? Like running Temperature and frequency?

 

So far I've played with taking screen shots while running the atomic burn tool, but I'm not seeing the numbers I expected. My system is NOT overclocked, and my 10850K is maintaining 4800MHz on all cores at about 72 degrees... Surely I'm doing something wrong for i not to be running hotter.

[[Support] Data-Monkey - netdata]

Error 101: Cannot Load JQuery

 

I found the cause and a solution:

 

The version of jquery on the netdata docker is 3.6.0 and while it seams like a newer version should work....it doesn't.

 

So I created a path that adds 2.2.4 to the folder from another netdata install (installed on my pfsense box)

[My Servers Early Access Plugin]

I had copied just the key file... I had installed from the USB Creator onto a new USB drive and registered the trial... Then installed my most important VM's and such. Then rebooted and was the victim of my own "cleverness". 

 

Rebooting with the trial key (which needs an internet connection to verify its validity and then start the array), on a system that houses it's own router in a VM, (which requires the Array to be started to run even though it's not, itself on the Array) might have been a poor choice.

 

I wonder... Was it the existing Appdata, System, and Domain folders that made it look like it had recovered? 

 

I might have jumped the gun and made an assumption. My appologies if so.

 

My real goal here is to get rid of the Cruft, that I have created over the past year of customizations to the Go file etc. for my old system.

 

Of course mixed into all of this is troubleshooting a few little hardware conflicts on the new system.

 

Thanks for the response

[My Servers Early Access Plugin]

I just performed a MAJOR update on my server hardware, new CPU, Mainboard, and smaller NIC. I spent HOURS getting it up and running to the point where it could serve the house as router (pfSense) and Media Streamer. Along with creating Users, Naming Shares, configuring Drive Mapping and installing some of my most used pluggins and creating my Hardware Centric Gaming VM. (You know, the important stuff)

And then I moved the key over to my new thumbdrive...

I assume it pulled my backup from "My Servers"?

Did I miss a warning?

It restore a backup of my flash drive destroying all my hard work and making the whole thing unusable...

Very frustrating.

[Notifications for failed fans & Fan Naming]

This would be interesting... I'm not sure how usefull it would be but it would definitely be interesting. The server I'm building has 7 fans in it, all pwm and all controlled in BIOS to set the speed based on CPU or mainboard temps... It would be interesting to see the dynamic responses to the work the server is doing... And if you paid attention you could adjust your fan curves to control cooling.

[Missing Fans]

In a previous build I had run through the installation of "Dynamix Auto Fan Control" and "Dynamix System Temperature" and run Sensors-detect and inserted the modprobe lines into the go file:

 

# modprobe for each sensor
modprobe coretemp
modprobe f71882fg
modprobe lm78
modprobe nct7802
modprobe i2c-i801

 

# Copy the sensor.conf file for use
cp boot/custom/scripts/sensors.conf /etc/sensors.d

 

In the end I had listings on the Dashboard for 9 fans with speeds for 5 of them... I have 5 fans in the system so all seemed right in the world.

 

* Please note I'm pulling the process from memory... So I could have missed a step.

 

I have since completely rebuilt the server, new build of the OS, but the fans are still plugged into the same spots and it's the same motherboard (EVGA Z170 Classified K).

 

Now I see only 3 fans, and when I run sensors-detect I see no mention of nct7802...

 

Does anyone have any insight as to where me other 2 fans went? Or why it's not reporting any empty slots? on the Dashboard?

 

I'm planning to use the final header on the mainboard for an additional set of fans, but would like to see the speeds they are actually running at.

 

Thanks

[My Servers Early Access Plugin]

Living out in the country, where I have 2 internet connections because they are either unreliable, or brutally restricted: I can't use the remote access, because both of my providers are double NAT'd and unable/unwilling to pass ports through.

 

If only there was some system in place like what is used by Teamviewer that connects my server to the Unraid system to allow me to follow it back in.

 

I don't know nearly enough to know if that is a huge deal, or if it is a huge security issue... Just thought I'd put it out there.

 

 

 

[NVMe Passthrough Problem (Samsung EVO 980 Pro)]

It's absolutely true that the file is not there... the trouble is I can't find any reference to virtio-win-0.1.160-1.iso.. Nothing should be asking for it. The VM's are all using 0.1.190.

 

I'm a little confused... You're right I had not bound it to the VFIO before... I believe that was prior to the newest unraid version, with its easier binding, and I was manually attaching it to the VM in the xml file... I notice the system reports unknown header type as soon Is I log into the gui as opposed to waiting until after I try to run the VM...

 

 

 

Not sure what else to try... 

 

Not sure what to do next to troubleshoot it.

[Uncast Episode 2]

Great podcast: I would not have guessed the topic of a server OS would make for such good listening, but it does the way you have done it.

 

I do have a question that arose from the discussion of VFIO allow unsafe interrupts:

 

I have a NVMe disk that looks to be misbehaving in the same way as you describe for video cards... I tried the VFIO allow unsafe interrupts switch but got no joy.

[NVMe Passthrough Problem (Samsung EVO 980 Pro)]

So I've tried with "VFIO allow unsafe interrupts:" set to yes but am getting the same results.

 

I swapped out the 660p for the 980 Pro - There is a Server 2019 Install on the 980 Pro... Checked that it was set to passthrough in the Unassigned Devices config Page and bound to VFIO in System Devices.

 

Same Error on startup of VM

 

If I edit the Windows VM it displays the drive as available and checked.

 

Here's the link to the Article about the same issue on a RedHat forum:

 

1542494 – VMs with NVMe devices passed through sometimes fail to be launched (redhat.com)

https://bugzilla.redhat.com/show_bug.cgi?id=1542494 

 

Any thoughts? I'm kind of stuck with this drive now.

[NVMe Passthrough Problem (Samsung EVO 980 Pro)]

Yes, I am and that could be contributing to the problem... I'll have another 980 Pro this weekend and will try it again.

[NVMe Passthrough Problem (Samsung EVO 980 Pro)]

Could this be related to the "VFIO allow unsafe interrupts:" setting?

 

I was listening to the Podcast today and it struck me... I was not restarting the VM... But just trying to launch it after boot... Could it have something to do with the host OS mounting the drive before restarting it for the VM?
