I've have a TrueNAS 12.0 U3 build that I've been chipping on the last few weeks, SuperStorage 6028R-E1CR12, Xeon E5-2600's, 64gb RAM, Broadcom 3008 controller, 10gbe, and happen to have SAS drives to populate the server with.

But SAS isn't smart capable? Correct me if I'm wrong, I am not a server engineer. This is all pretty new to me.

I see a lot of SAS setups out on the internet with TrueNAS. They show up, I build my pool and vdev, everything is good.

But what are the best practices for health checks / maintenance?

I brought this up because running a manual test in the GUI kicks back an error. I can't view results. And the TrueNAS forums are littered with SAS conversations about how SMART isn't really supported. I am very confused as to why the GUI is just failing left and right for me when it comes to implementing a health check workflow.

Well TrueNAS in the GUI just gives me an error when I start a test, and I can't view any results at all. The test does continue to run in the background, even though I was given a vague error on start.

But if I run or view the test in terminal, here is the output.

You could open a ticket for this with iX?
If its actually working fine, just a gui issue then they might be able to do something about it...

I filed a bug report and logs, they actually market the ticket as resolved, so it should be fixed in a future update.

I'm in the same boat, doing anything SMART related from the GUI spits out a bunch of errors, but CLI works fine. Truenas 12.0 U3.1 here, and all of my drives happen to be SAS.

Are the bug reports and such publicly available? I'm very curious as to how/when this will be fixed.
