I am still trailing Unraid 6.9b35 and after I managed to get couple of container and shares up and running I created a Win10 VM which seems to kill my parity disk.

 

Symptoms: I spin up the VM and use it to browse the web, suddenly the parity disk turns red, disabled and the sys log is full of errors. I wonder if my cache disk setup could case the issues. The VM is stored on the cache disk.

When I stop the array, remove the disk, add in again I can start a parity sync which has run for 3hrs with turbo write (constantly 182Mb/sec) without issues. Starting the VM again ended in the same result as described above.

 

System setup:

 

3x4 TB WD Red

2x 512GB SSD + 1x 250GB as Cache Pool Raid 1

 

Any advise how I can troubleshoot this? Diagnostics attached.

 

Thanks all!

issue so far solved

Diags are after rebooting with parity already disabled, re-sync it then grab diags after it gets disable and post those.

I managed to copy parts of the sys log.

Moved the VM from Cache to HDD and so far no issues. Didn't test with a new VM on the SSD cache yet as I am afraid this will trouble the parity disk again.

 

Any further advise?

Not enough info, those errors are likely about the docker image, we'd need to see the beginning of the problem.

@doesntaffect What devices are you passing through to the VM? Any USB devices, controllers or disks? A complete diagnostic would be helpful

So far the system has been stable for a couple of days after I changed my Cache config from 3 NVMEs (2x512+1x250; the latter in a PCIe 1x converter card) to just 2x512GB. The single NVME has been turned into a separate cache, obviously without any Raid config.

The Win10 VM is behaving fine, even with heavy load on the host and the VM over a couple of days. I'll mark this as solved since I cannot provide a copy of the original diagnostics.

 

Thanks guys!
