Fonzarelli Posted November 4, 2017 Share Posted November 4, 2017 I just noticed this today. Should I be concerned about this error and replace the drive, or is this not something to worry about? Link to comment
JorgeB Posted November 4, 2017 Share Posted November 4, 2017 It's never a good sign but check if it passes an extended SMART test. Link to comment
Fonzarelli Posted November 5, 2017 Author Share Posted November 5, 2017 Here is the result of the extended SMART test. It says the overall test passed but it also shows Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed: read failure 60% 4427 842782376 The parity that is failing is a 6TB where all the other drives in my array are 2 and 4TB. not sure if it is less concern for failing sectors considering there is lots of room to rewrite the data in another sector. Or am I wrong? I bought the drive only a couple months ago, but it was in an external enclosure that i broke open so no warranty. smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.9.30-unRAID] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Western Digital Blue Device Model: WDC WD60EZRZ-00RWYB1 Serial Number: WD-WX81D65CAT95 LU WWN Device Id: 5 0014ee 261dc6eca Firmware Version: 80.00A80 User Capacity: 6,001,175,126,016 bytes [6.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5700 rpm Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-2, ACS-3 T13/2161-D revision 3b SATA Version is: SATA 3.1, 6.0 Gb/s (current: 3.0 Gb/s) Local Time is: Sun Nov 5 07:46:49 2017 PST SMART support is: Available - device has SMART capability.

JorgeB Posted November 5, 2017 Share Posted November 5, 2017 17 minutes ago, Fonzarelli said: It says the overall test passed but it also shows That doesn't mean anything in this case, just that the SMART attributes are within limits. 17 minutes ago, Fonzarelli said: Completed: read failure This is the the result of the extended test, and it failed with a read error. 19 minutes ago, Fonzarelli said: The parity that is failing is a 6TB where all the other drives in my array are 2 and 4TB. not sure if it is less concern for failing sectors considering there is lots of room to rewrite the data in another sector. Or am I wrong? That's not how it works, that LBA is before the 4TB mark, so if another disk fails and you need to rebuild it there will read error(s) resulting in a corrupt rebuild. You could try preclearing the disk (or re-syncing parity) since sectors are only remapped on writes, and then run another extended test to confirm if it's now good, but I personally would just replace it.

Fonzarelli Posted November 6, 2017 Author Share Posted November 6, 2017 Thanks for the advice johnnie.black. I did a pre clear and am about to re-sync parity. but regardless I think im going to order up a new drive like you said just because its not worth the chance of failure. ############################################################################################################################ # # # unRAID Server Preclear of disk WD-WX81D65CAT95 # # Cycle 1 of 1, partition start on sector 64. # # # # # # Step 1 of 4 - Zeroing the disk: [12:12:29 @ 136 MB/s] SUCCESS # # Step 2 of 4 - Writing unRAID's Preclear signature: SUCCESS # # Step 3 of 4 - Verifying unRAID's Preclear signature: SUCCESS # # Step 4 of 4 - Post-Read verification: [12:23:11 @ 134 MB/s] SUCCESS # # # # # # # # # # # # # # # # # ############################################################################################################################ # Cycle elapsed time: 24:35:46 | Total elapsed time: 24:35:47 # ############################################################################################################################ ############################################################################################################################ # # # S.M.A.R.T.
