I have a raidz2 pool with 8 drives.
I got an alert from a smartctl test:
The drive model is a WDC WD40EFRX-68WT0N0
Error is:
There appears to be 17 errors if I run
I thought about following this procedure: https://www.truenas.com/community/t...guide-basic-common-failures.41026/post-323590
However the guide clearly states that this is a destructive procedure.
What will happen to my raidz2 pool after I run this? If the procedure fixes the problematic sectors in this drive, can I salvage the pool by running a scrub? If the drive is failing then I'll need to replace it anyway, just wondering if this process impacts the pool itself or if a scrub will fix the random data written into those blocks.
Thank you for the assistance.
I got an alert from a smartctl test:
* Device: /dev/ada3, Self-Test Log error count increased from 1 to 2.
The drive model is a WDC WD40EFRX-68WT0N0
Error is:
* Self-test execution status: ( 121) The previous self-test completed having the read element of the test failed.
There appears to be 17 errors if I run
smartctl -x /dev/ada3
(log is attached), however I only get detailed list about 7 of them. I'm not that fluent in understanding the smartctl report so perhaps it only lists the last errors.I thought about following this procedure: https://www.truenas.com/community/t...guide-basic-common-failures.41026/post-323590
