The following errors are popping up in the FreeNAS UI:
CRITICAL: Dec. 30, 2017, 10:18 p.m. - Device: /dev/da2 [SAT], 1 Currently unreadable (pending) sectors
CRITICAL: Dec. 31, 2017, 5:21 a.m. - Device: /dev/da2 [SAT], ATA error count increased from 16 to 17
But after running a long SMART test (smartctl -t long /dev/da2), it passes, there's no bad blocks listed under LBA_of_first_error (nor Current_Pending_Sector) despite the results indicating 17 ATA errors like the UI did. I'd like to try resolving this and extend the life of this drive/pool by zeroing out the bad sector(s) - I'm experimenting here, the data isn't important. But is there really a critical error here? If so, how do I find the true bad sector(s) to zero out (or fix the true issue)??
Below is the output/results of the long SMART test.
