1st ever disk read errors, extended SMART OK?

[Capt.Insano]

I have been running an unRAID server for just shy of 7 years and last night for the first time I received an alert of some read errors on a disk.

 

disk 3 (WD Red 3TB) on my array shows 153 read errors.

 

I re-ran parity check as a precaution and no errors reported. I also ran an extended SMART test (attached) and the drive passed.

 

I would really appreciate advice on whether I restart the array to clear the errors or should I be looking at replacing the drive?

 

Thanks to all

It was reported on the log as an actual media error, and SMART suggests the disk has seen better days, still and since the SMART test passed it's OK for now, but keep an eye on these attributes, if they keep increasing it will likely fail again soon:

 

ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
  1 Raw_Read_Error_Rate     POSR-K   200   200   051    -    501
200 Multi_Zone_Error_Rate   ---R--   200   200   000    -    41

P.S. you also have an issue with on one of your cache devices (cache1)
