disk has read errors

[wgstarks]

I recieved a warning that disk 4 has read errors. The disk is not disabled though. Still has a green dot. Not sure how to correct this?

It's logged as a disk problem, but the sectors were successfully re-written, hence the disk remaining enable, good idea to run a SMART extended test, and if it passes monitor this attribute, you can add it to the SMART attributes monitored by Unraid for any WD disk, if it continues to increase there will likely be more errors soon:

 

ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
  1 Raw_Read_Error_Rate     POSR-K   200   200   051    -    35

Started an extended test. 
 

How do I get the warnings from UnRAID to stop?

You can acknowledge SMART warnings by clicking on them on the Dashboard page. To get the error count reset go to Main - Array Operation and click on Clear Stats

No warnings are showing on Dashboard. Disk 4 shows healthy. The only place I’m getting the warnings is in the daily status report email as far as I can tell. Is it possible that the Status page reset when I started the extended smart test?

Have you stopped and restarted the array? It's possible a reboot may be needed, but I don't think so.

Haven’t performed any array operations. I’ve set the array health reports to hourly (rather than daily) just to see if it still shows a warning. Still waiting for the next report though.

If the disk is showing anything but zero in the Errors column on Main - Array Devices, then you will get the warning. Clear Stats should set that column to zero or you will have to reboot to clear it,

Clear Stats didn't reset the value-

I'll try a reboot later although I've never noticed that rebooting changes the SMART values.

Sorry, after I actually paid attention to what you posted I realized I was looking at the wrong item completely. Clear Stats cleared everything except the errors. Rebooting cleared the errors. Thanks for the help.

SMART is stored by each drive within the drive and can't be affected by reboots or anything Unraid does.
