Cache pool errors after upgrade to Unraid 7 with two different servers

Featured Replies

Hi all,

 

I upgraded 2 servers to Uraid 7. Both servers had an error with the wrong pool state error. Dockers and VM didn’t run because of this.

On the first server removing the pool and adding it again as described in several topics solved it.  Dockers and VM are running again on that server.

 

On the second server I did the same, but I get an error that it’s “unmountable: unsupported or no file system” message. Also I see one of the drives in the unassigned disc section. See screenshot.

 

Dockers and VM’s don’t run because of this.

 

Any ideas how to solve this?

 

I attached the diagnostics file

One of the NVMe devices is being passed through to the VM, so when the VM started it dropped, correct that, reboot and post new diags after array start:

 

06:00.0 Non-Volatile memory controller [0108]: Sandisk Corp WD Black SN850X NVMe SSD [15b7:5030] (rev 01)
    Subsystem: Sandisk Corp WD Black SN850X NVMe SSD [15b7:5030]

 

-device '{"driver":"vfio-pci","host":"0000:06:00.0","id":"hostdev0","bus":"pci.0","addr":"0x6"}' \

Thanks for your response. I already checked that, but in the settings 'passed' is not turned on as you can see. Also it doesn't say 'passed' but 'array'. I can't get in the VM settings because Libvirt Servic failed to start.., so I can't check things there.

That's the UD plugin and completely unrelated, it's being passed through in the VM config, you need to edit that (VMs - Click the VM and edit)

That makes sense.. But I can't edit the VM because of this Libvirt Servic failed to start error because it's on those cache pool drives.

If the VM is not set to autostart, reboot and post new diags after array start.

Before doing anything else, edit the VM and removed the pool NVM device from being passedthrough, them post the output from

 

btrfs fi show

Can you help me where I can edit the VM when I can't see it? I'm a bit clueless..

There's no partition, type

sfdisk /dev/nvme0n1

then type 2048 and hit enter, don't do anything else after, just post the output

Hit CTRL + C to abort, and repeat the same, but with 64 instead of 2048

I will test that. Thanks.

I looked into it but it's too complicated for me. 

 

I think I will format both discs and set up a new cache pool and start over. That probably is faster.
