Last night, unraid was on without much going on. I put on a movie and noticed it was lagging so I checked unraid. Parity disk was throwing out errors then got disabled and the lag stopped. I got the diagnostic to see if you can spot anything causing the issue this time.

Since this has happened before, I did what support said and checked the cables and tried different once. I turned off the array and deselected the parity 2 disk then started the array. Then turned it off again and reassigned it. The parity build was working till another disk got disabled but parity 2 is still being built.

 

Since disk 4 got disabled during parity 2 rebuild, is the next step let it finish rebuilding parity 2 then troubleshoot the same again for disk 4? Attached the newest diag

Yes, these look more like a connection/power problem.

You can wait for parity2 to finish syncing before dealing with the other one, but also need to find out what's causing the problems, I would start with replacing the miniSAS cables and if that doesn't help try a different PSU if available, or another HBA.
