Below is the history from my monthly parity checks. Ever since I replaced my Parity Drive with a 14tb, this is a monthly issue whenever the scan runs.  Where do I start?

Adding diagnostics

Not quite sure what question you are asking?   

 

If it is the very large value in the Errors column then this might be due to the part of the parity drive beyond the size of the previous one not being correctly zeroed by Unraid when the new one was added (there have been reports of this happening).   These errors would keep being reported until you run a correcting check after which the count should return to zero for subsequent runs.

 

If you use the History button on the Main tab that data will be better formatted   

 

The entries with the extra fields are ones where you have had the Parity Check Tuning plugin active and it has added to the entry with information it has gathered.

More or less just trying to figure out why these errors would occur.  I have these errors corrected automatically while the Parity check is running but it keeps coming back.  Took a quick screenshot to help with the formatting.  

Are you sure it is a correcting check?  Without the extra information added by the Parity Check Tuning plugin one cannot tell from the history.

 

It might be possible to tell if you attach your systems diagnostics zip file (obtained via Tools->Diagnostics) to your NEXT post covering a period where this has happened.
