TrueNAS failed to read SMART values and Self-Test Log Failed

TrueNAS General

System is as follows:
Dell Poweredge R740 16x2.5" chassis
Xeon Gold 6150 x2
128g DDR4
Dell HBA330 12g Non-RAID controller
600gb 10k 12gbps SAS x 12
Dell 200g SATA SSD boot drive

In truenas I am getting smart value errors on 4 of the drives looks like and self-test log failed. After a clean installation I believe I got them on all drives, however I did a sg_format --size=512 on several of them that were showing 0gb from running lsblk.

Here is one output from smartctl -a /dev/sdl

I have looked over several posts here and other places, but it appears since I am not too experienced in this type of troubleshooting I need assistance :slight_smile:

Thanks!

When there are multiple drives with issues, its worth considering whether the SAS/SATA expander is the issue.

The puzzling part of report was:

Non-medium error count: 405759

Hey Captain_Morgan,
What does that error count usually point toward? Also, since I have formatted them with a 512 block size there have been 0 warnings or errors and it has been 4 or 5 days.

Thanks!

No idea, but I just thought it was an indicator of underlying issue across multiiple drives. It looks like the 512B block size format has solved the issue. (may have been drive firmware).

Well done! I’ll mark this as solved.

Ahh, ok! Yes, it does appear that has fixed the issue. I did have to format all the drives, not just those 4 :slight_smile:
Ty!

You may never know, but the HBA could have caused the issue and needed the drives to be 512B formatted.
