Array has disc with 32 read errors - what should i do?

[desertfox_0815]

Hello,

 

over last night i've got a disc with 32 errors on it.

smart short test returned no errors.

disc is still healthy

diags are attached.

 

 

These are the errors found in disc log

 

its a toshiba n300 8tb disc running on a lsi 9205-8i hba on a sas-to-sata breakout cable.

disc is still running fine.

 

i've entered maintenance mode and did a filesystem check with -n and without option. no errors found and no errors corrected.

 

what should i do? is it safe to simply run the array? should i format the disc and rebuild it?

 

thanks alot

Fix Common Problems just noticed that disc3 has errors but says:

"If the disk has not been disabled, then Unraid has successfully rewritten the contents of the offending sectors back to the hard drive."

 

So i guess data should be valid?

SMART looks fine and errors occurred right after spin up, so you may try disabling spin down if it happens again.

Thanks Jorge for checking it. 

Currently im running a extended smart check. looks like all data is fine.
