Smart errors in GUI

[KentShades]

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:

So Im wondering should these be replaced? Im not so sure.

 

[dlavigne]

Are da1 and da2 SMART capable?

 

[SweetAndLow]

Are da1 and da2 SMART capable?

yeah this, are they your boot devices or something?

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:
