WannabeMKII Posted December 1, 2020 Share Posted December 1, 2020 (edited) Fix common problems is reporting that my parity drive is reporting read errors - Drive log attached. I've been an UNRAID user for 4 years now and love it, but this is the first time I've had a potential disk error. Would someone be able to check the log file for the drive please? If more info is needed, please let me know. If it is a potential drive failure, what are the correct steps to take to resolve? Many thanks.

codearoni Posted December 1, 2020 Share Posted December 1, 2020 Hey! Another WD Red user! See my thread from a couple of weeks ago. The extended SMART results mean different things for different brands of drives. I'll let someone more knowledgeable than me confirm, but your drive might need replacement. Quote Link to comment
codearoni Posted December 1, 2020 Share Posted December 1, 2020 Also, traditionally it helps to attach general diagnostics in additional to the SMART results. Tools -> Diagnostics -> Download. Quote Link to comment
JorgeB Posted December 1, 2020 Share Posted December 1, 2020 Disk is showing some issue, run an extended SMART test. Quote Link to comment
WannabeMKII Posted December 1, 2020 Author Share Posted December 1, 2020 Thanks for the steer. I’ve started the extended test and will post the results when it’s finished. Assume it’s the same log file? Quote Link to comment
codearoni Posted December 1, 2020 Share Posted December 1, 2020 From the Disk's personal page: go to the section labeled "Self-Test" and click the "Download SMART report" button. If you've done a short SELF test, then yes, the same button. Quote Link to comment
WannabeMKII Posted December 2, 2020 Author Share Posted December 2, 2020 Extended test report attached. Does this help diagnose? WDC_WD40EFRX-68WT0N0_WD-WCC4E2ND35EL-20201202-1141.txt Quote Link to comment
JorgeB Posted December 2, 2020 Share Posted December 2, 2020 SMART test passed so the disk is OK for now, the but previous errors are logged as actual disk errors, so you want to keep an eye on it, especially this attribute: ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 1 Raw_Read_Error_Rate POSR-K 200 200 051 - 1528 If it continues to increase the disk will likely fail again soon.

WannabeMKII Posted December 2, 2020 Author Share Posted December 2, 2020 Many thanks for the info. I'll keep an eye on the raw value. Is there a way to set an alert if this number is to increase? Quote Link to comment
JorgeB Posted December 2, 2020 Share Posted December 2, 2020 You can add that attribute to SMART monitoring, I recommend monitoring that one plus attribute #200 for all WD drives. Quote Link to comment
WannabeMKII Posted December 2, 2020 Author Share Posted December 2, 2020 OK, I've added '1,200' under SMART attribute notifications. I assume I'll get a message if the numbers change? Is that how it works? Quote Link to comment
