Unraid ver 6.9.2 - Unstable - Assistance please

[Vetteman]

Presently having stability issues with my Unraid install. I am a newbie when it comes to Unraid. However I worked 30+ years as a sytem admin (now retired) first with Novell Netware 3 - Netware 6, Citrix Winframe, Windows Servers, Novell SUSE servers. All were file & print servers. At home I've been using Samba services & mdadm raid on a Zorin-Os (Ubuntu based) computer shared with Windows computers for close to 15 years.

 

I was attracted to Unraid by the wonderful SpaceInvaderOne fantastic videos on youtube and thought it would be a good solution to the growing web of USB external drives I use to backup my raw DSLR photo files and processed PSDs and JPGs. Also for my 3D rendered illustrations and growing collection of 3D models and assets. My goal is to replace my USB drives backup solution with a NAS solution. Getting rid of the spider web of USB cables and electrical connections.

 

I used the trail version of Unraid for over two weeks and was quite impressed with it's stability and ease of use. However since purchasing Unraid and installing it on the same hardware I was running the demo (I7-4770S, Gigabyte GA-H97-D3H, 32 gigs of DDR3, using onboard intel graphics). Previously I used this setup for 3D rendering on Windows 7 Home 64 bit. The only exception was I used a Nvidia GTX 1060 card. I removed the card when I ran the demo of Unraid and have not put it back into the computer. The computer was rock stable when doing 3D renders and sometimes running for a couple of days at high utilization. I use e-onsoftware's Vue which is a hybrid renderer using both gpu and cpu. I also use DAZ3D's Iray renderer.

 

Since purchasing Unraid, it has been very unstable. Crashing sometimes overnight for no reason that I can discern. Not sure if it maybe my KVM (keyboard, monitor, mouse USB switch) or the macinabox docker which I installed. I have a APC UPS connected to my Unraid server.

 

I did run a memtest for over 30 hours and no errors were reported. Refer to attached screen shot. Also enabled the syslog server option and  the syslog saved to one of my Unraid shares.

 

Presently I am very reluctant to backup my photo files and 3D assets to a very unstable Unraid environment. I would like to resolve this issue as I find Unraid's instability very concerning. Never have I encountered a situation like this with the various operating systems I've supported both at work and at home.

 

I eagerly await a response on this matter.

 

Thanks kindly and Merry Christmas to All of You...

Try getting rid of the KVM.  It's having constant reconnections spamming the logs

Thanks kindly for the reply. By doing a check disk you mean this option below?

 

I certainly can remove the Unraid server from my usb KVM switch but I do not have enough desk space to place another keyboard and monitor.

 

I have 4 computers on my desk. The Unraid server, Ubuntu Samba server and a Windows 10 running Storage Pools connected to the KVM and a monitor, mouse & keyboard.

 

I have my photo editing/3D modeling computer Ryzen 7 computer with two dedicated monitors, keyboard and mouse. Not on the KVM.

 

I would have to run the Unraid without a monitor, keyboard or mouse. And when I start exploring VMs that maybe an issue as I dislike VNC and Nomachine solutions.

But I may try this once the parity check stops running from last nights/morning crash (Dec 25 just after the midnight of Dec 24).

Cheers & many thanks

I deleted that comment, as it was actually your unassigned disk that you then began to preclear

And the KVM suggestion was to simplify things as it's causing issues (I seem to recall when I had a KVM on my system it did the same thing -> poor design of the KVM when it's not switched)

[Vetteman]

I wonder if there is a KVM which Unraid users use that does not cause this issue.

Thanks kindly Squid for your suggestion. I will give it a try.

I connected an usb mouse & keyboard directly to my Unraid server. And Unraid seems to be a lot more happy as the syslog is a lot less chattier.

The server stayed up for 4 days. However I decided today to launch one of my vms - Windows 11,  which I am passing thru the Intel onboard video to the vm. I read that the i915 onboard video plays havoc with the new linux 5.x kernel. So not sure if this is my problem or not.

 

About 10 minutes after launching the vm, graphics on the monitor went strange, displaying about of streaks on the screen. Unraid did not respond to a ping from a Windows client nor could I connect via the web interface.

 

So I did a hard reset.

 

Please see attached syslog

My vms seem to be stable when I switched my graphics from passthrough to vnc.

 

I do have a GTX 1060 with 6gb of ram sitting on a shelf, but I was hoping to use the free PCIe slot for a SATA controller card.

[Vetteman]

Since I removed my Unraid box from the KVM switch and removed the Intel onboard graphics from my vms, using vnc instead, everything seems quite stable. No crashes or freezing. Damn Intel graphics and a flakey TrendNet kvm switch seemed to be the culprit.

 

Thanks to those that commented.
