UNC Errors Reported on Parity Drive

During the weekly parity check, Unraid reported read errors on the parity drive. The message in FCP suggested that the data had been rewritten back to the drive successfully.

 

I checked the SMART reports and ran both a short and extended self test. Both came back "Completed without error", but both test reports show a set of UNC errors within the report, but also "SMART overall-health self-assessment test result: PASSED" (extended test report is attached).

 

The Main page of the server UI states parity is valid.

 

From all this I think the disk is not in need of immediate replacement, but I should keep an eye on it. 

 

I'm also thinking it might be wise to replace it, but maybe keep the current disk as a spare?

 

I welcome any suggestions and insights you care to share.
