Parity Check Issue 7.0.1

By tknz

· 502 views
  • Solved
  • Minor

Running Unraid 7.0.1 I have been having parity check crashes around the 70% or higher mark after a couple of days. The system otherwise seems stable, and the array functions normally except during parity operations.

 

Once the bug / fault triggers unraid parity check slows down from 100MB/s to a few KB/s but I presume this is because the unraidd thread has crashed or had a panic. 

 

I completed a memtest last night with no issues. I do run the new ZFS plugin across 3 NVME cache drives, and I also (have for years) run SR-IOV to virtual GPU pass through to a windows VM running BlueIris CCTV.
