Does hexos run SMART/scrub tests?

[Jakor]

Doing some research last night, I noticed that most people running truenas will run daily or weekly scrub tests on their HDDs.

HexOS and the truenas dashboard have always said my drives are healthy, but I suspect that’s because there weren’t any logged smart tests. To be safe I ran a short smart test on all three drives - no errors popped up, but now I’m wondering - should I be running these tests on a schedule in the truenas interface, or were those features already included in the HexOS beta?

Hello,

No, currently you have to schedule the jobs in truenas, Hexos is not running them.

Thank you for confirming! Does that mean that HDDs could fail without warning in the HexOS beta if someone did not know to set this up? If so, shouldn’t this be added to the installation tutorial to warn new users that they should be setting this up to protect themselves from data loss?

Not necessarily, a drive can also die without showing any signs in SMART tests and Hexos/Truenas does check the passiv SMART values and does monitor and detect possible drive failures.

But SMART self tests go a step further and actively scans the disk surface and internals for issues not detectable without SMART test.

While SMART self tests are strongly recommended, it is not like there would be no monitoring without it.

Thank you - that is reassuring.

 

i also noticed this morning that there already are scrub tests scheduled every 3 days in the truenas UI - so i assume that was at least configured by HexOS. I’ll probably add my own scheduled SMART tests every week or so just to be safe.
