[Windows 10 VM execution Error when I try and passthrough a GPU]

So the past weeks, i managed to backup my data as mentioned above, but it seem it was just a display error because after i finally started my array yesterday to restore the data and after i started the drives were shown as normal and everything was still there. I still do recommend doing a full backup of your data/server.

 

i followed this video from spaceinvador one

 

after that i set my PCI ACS override to Downstream

and after a reboot all my IMMOU Groups are looking good and my VM is starting again.

 

Thank you harshl!

I managed to backup my data form the cache pool thanks to this guide

 

 

 

i just had to use nvme0n1p1 as drive letter

also whats not mentioned, you unassign the two cache drives and start the array so you can copy your data

to one of your disks/shares in /mnt/disks/...

hey thank you for the information. I must have overlooked that video from him as i researched.

 

i started with his first assumption

to add "vfio-pci.ids=10de:17c8,10de:0fb0,1d6a:d107"

 

after i rebooted my server i think i have now a much larger problem since

 

it shows my cache drives as new drives.

i tried to remove the line i added and reboot the system but it still says both of them are new drives.

 

and as dumb as i am i didnt do a backup of my cache files in the past month so

is there any possibility to access my files from them?

i didnt start the array yet.

it was btrfs raid1

 

edit i see them in Unassigned devices

 

i also still have the 2 old caches drives i swapped at the weekend.

[Windows 10 VM execution Error when I try and passthrough a GPU]

Hey i have a problem with my Windows 10 VM

 

system overview

unraid OS Version 6.8.3 2020-03-05

CPU Intel Xeon E-1246v3

MB ASRock Z97 Extreme v6

GPU Gainward Nvidia 980Ti GS

 

a situation summary:

i shutdown my server for a few hardware upgrades, two NVMe SSDs for the cache and a 10GbE Card.

I also used that to do a BIOS Upgrade.

After that i started unraid and my array and followed this guide to change my cache drives

this worked fine for me. then as i wanted to start my Windows 10 VM i noticed that the GPU i have installed didn't showed up in the VM settings

 

I searched and found out that i need to enable IOMMU pass-through or Intel VT-d (for me) in my BIOS

since the BIOS settings got reset after the upgrade i checked everything again and booted my system up again.

 

my error:

Now the GPU showed up in my VM again and everything looked good so far.

but when i start the VM the following error occurs

 

internal error: qemu unexpectedly closed the monitor: 2020-06-16T17:56:01.149672Z qemu-system-x86_64: -device vfio-pci,host=0000:01:00.0,id=hostdev0,x-vga=on,bus=pci.0,addr=0x5: vfio 0000:01:00.0: group 1 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver.

 

so i checked the IMMOU groups and i have no idea why it would group itself like that

 

 

VM settings

 

so i did some research and found this

 

but i didnt really get the solution so i wanted to ask what should i do.

enable PCIe ACS (also which one)

Or do that vfio-bind (and how)

[Array won't start anymore]

The Array works again!

It worked exactly as you said.

 

For Short:

Start the Array in maintenance mode

go in the corrupted disk menu and

start xfs_repair option:      <-blank for repair

if error occures follow the help and run

xfs_repair option: -L

and after that again

start xfs_repair option:      <-blank for repair

 

that worked for me.

 

Thank you very much everyone!

[Array won't start anymore]

I first started xfs_repair with -n as option after that i started to start the repair again with "blank" in th eoption field as described in the help.

This gave me the following error report:

Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed.  Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair.  If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.

So as i can't mount my disk I should run xfs_repair with the option -L am I right?

[Array won't start anymore]

Again the required zip file.

I tried to start the array in maintance mode so that works.

Should i try to start my array without my disk 2 and/or 7 to check if one of these disk are causing the error?

 

[Array won't start anymore]

Thank you for your help

 

Here is the required zip file.

 

[Array won't start anymore]

So first of all I'm from Germany I hope you can follow my english.

 

My Problem:

I can't start my Array anymore

I reboot the server and when I hit the Start Button in the webinterface it ends in an loading loop.

When the array isn't started unraid and webinterface works just fine.

The first time i was able to reboot the server with putty after that

I couldn't shutdown or reboot the server over the console in putty and needed to do an manual forced shutdown through press button method.

Only when it isn't in the loop.

 

I have now 2x forced the shutdown so unraid wants to start an parity check when i start the array.

 

What I did before the error occured:

I disabled disk 2 in my media share and enabled read& write for my user

I moved via Windows Explorer from Disk 2 (2TB HDD) to Disk 7 (4TB HDD) ~300GB Media Files mkv mp3 etc pp...

Then the copy process abortet due an "unexpected network error"

I don't know what occured it maybe that the windows backup started during the copy process. It also stopped due an "unexpected network error"

my media share contains disks (2),4,6&7

my backup share disks 3&5

so there should be no conflict due the disks.

 

What is functional.

I can login via putty as root

I can restart the Server and the webinterface starts

I can ping my unraid server 192.168.xxx.y

 

My Specs:

Unraid Server Plus v6.3.3

Intel Xeon 1246v3

32GB RAM

2x480 SanDisk Ultra II SSD as Cache

7 Different sized HDDs all Seagate only one WD

1 Seagate 4TB Parity

2x LAN setup as backup
