So I come in to look at my freeNAS today and I see a bunch of error that Im not sure if theyre real errors or not.

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da1 [SAT], Read SMART Error Log Failed

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da1 [SAT], Read SMART Self-Test Log Failed

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da1 [SAT], failed to read SMART Attribute Data

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da1 [SAT], not capable of SMART self-check

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da2 [SAT], Read SMART Error Log Failed

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da2 [SAT], Read SMART Self-Test Log Failed

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da2 [SAT], failed to read SMART Attribute Data

  • CRITICAL: July 4, 2019, 2:41 p.m. - Device: /dev/da2 [SAT], not capable of SMART self-check

I run a smart check and pool status and everything seems fine. I ran smartctl -t short /dev/da1 and da2 and both are the results below.

Code:

Those are the disks, and no these are not boot devices. Just disks that have been inserted but are spares. I've since done a long test on this and got the following:
