I tried searching around but couldn't find much on this. As long as I don't reboot Unraid, it won't have parity errors. Most recently, I ran the parity three times in a row without rebooting, and it reported 0 sync errors each time. I then rebooted (safely, stopping the array and then rebooting) and started another parity check, and now there are errors. I see a consistent 1025 errors on this particular Unraid box when errors do pop up, which is suspicious. Looking at the parity check history, there are only ever errors after a reboot.Â

Parity History, showing the last three runs had zero errors:
I then immediately rebooted and started another parity check, taking this screenshot:

This is a Supermicro motherboard with ECC RAM. Unraid is running as an ESXi 6.7 VM, with the Intel SATA controller passed through to the VM
I have a second Unraid server with the same setup (albeit newer hardware and newer ESXi), and it does something similar: 0 errors on repeated Parity Check operations, but the second I reboot and try to run a parity check, it'll start finding errors.Â
Both Unraid systems have been running as VMs for a few years, and did not always have this issue.
Â
I've tried running New Permissions just in case something wacky happened to some of the files, but that did not help.
Â
Diagnostics from both systems attached. The parity check errors can be seen in one of them. I can grab new/better diagnostics later if need be.Â
Â
I'm looking for help in troubleshooting next steps, as this leaves me less confident in restoring valid data should a drive fail.Â
I did find this blog post https://blog.insanegenius.com/2020/01/10/unraid-repeat-parity-errors-on-reboot/ which has the same errors I did, "Jan 3 10:03:07 Server-2 kernel: md: recovery thread: P corrected, sector=1962934168"Â
but I don't think it's relevant in this case as I'm just using the SATA ports directly on the motherboards, without using any LSI or SAS/HBA cards.Â
