Hi all I am getting some read errors on my parity drive with the notification ```
If the disk has not been disabled, then unRaid has successfully rewritten the contents of the offending sectors back to the hard drive. It would be a good idea to look at the S.M.A.R.T. Attributes for the drive in questionBegin Investigation Here```

 

I am not sure how to go about fixing this and have tried looking into logs and the SMART attributes but dont really know what to look for.

 

Here are my diagnostic logs.

SMART attributes for all disks looks fine, and none are disabled. If it happens again you might check the connections, and/or run an extended SMART test.

 

Do you have Notifications setup to alert you immediately by email or other agent when a problem is detected?

 

Your docker image is unnecessarily large. You are very unlikely to need even 20G unless you have something misconfigured, and making it larger than 20G will not fix that problem. Have you had a problem with filling it up in the past?

Looks like an actual disk problem, though these errors can be intermittent, run an extended SMART test on parity.

@Trurl No I havent had issues I just made it 20G so i wouldn't have to go back and change it if i needed more space.

 

@johnnie.black Thanks I'll give that a try.

Can I leave the array up to do that or do I need to bring it offline?

Up, though if possible do it when parity disk usage is expected to be low.

IOW, when not writing to the array

So the extended SMART test finished without errors but i still have that warning.

The drive error count displayed in Main - Array Devices won't reset until you reboot.
