Hi All,
I had my first degraded pool in my home box. One of the WD red Drives (Bestbuy 8tb pull) was generating cksum errors. I went out to get a new replacement drive from BB since they were down to 149 ea and i was able to get red label based on SN and model number. I replace the drive causing issues. Here is a snip of the resilvering process.
I ran a smartctl -t long on the drive reporting issues and here is the smart info, it still has 10% of the test left.
Few questions:
should i worry about this drives integrity?
Will smart test show if the drive is bad, if so what values should i be aware of?
Can anyone tell from the current smart results anything?
Anything else i can do to check for issues?
additional info:
Freenas is running as a vm on esxi 6.5 latest build. It has 64 GB ram. the HBA are pass through, the disks are in a SM hdd chassis that is brand new. no other issue reported with any other drive (many are WD Red 8tb from bestbuy). I also patched Freenas to latest version prior to resilver. The pool is fine now with replacement drive.

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.should i worry about this drives integrity?
Will smart test show if the drive is bad, if so what values should i be aware of?
Can anyone tell from the current smart results anything?
Anything else i can do to check for issues?
