Parity Drive received errors during Parity-Check that had 0 errors??

[FQs19]

I'm a bit confused on what happened to my parity drive during a non-correcting parity-check. 

 

My parity drive has 513 errors on it from doing a parity-check which finished with 0 errors. 

I see an i/o error in the logs, but not sure what happened. 

I haven't touched the hardware inside my server for months, so none of the cables, drives, memory sticks were touched. 

I also don't see any errors in S.M.A.R.T. attributes, but there are four ATA Errors in the S.M.A.R.T error log.  

I did a short S.M.A.R.T. test and it passed.  

 

Anyone have a clue what happened here?

Thanks for looking.

It's logged as a disk problem, but it can be an intermittent issue, run an extended SMART test.

Running it now. 

Will post logs when finished. 

Thanks.

The extended smart test just finished with zero errors. 

Attached are the logs for your review. 

I have not restarted the server yet or changed anything in unraid. 

 

Thanks again for looking at this.

Since the test passed disk is OK for now, reboot to clear the errors and keep monitoring, swapping cables/slot would also be a good idea to rule that out if it happens again to the same disk.

I re-seated all cables and hba card. 

I didn't notice anything out of the ordinary. 

Drive errors cleared after restarting. No more issues detected so far. 

I'll keep an eye on the drive and will replace it under warranty if it happens again. 

Thanks for the help.
