TrueCommand Reports disk failing SMART, FreeNas doesn't

Hi all

So I started playing with TrueCommand a while back, and have just left it to gather data. But I noticed after destroying a pool and rebuilding it, that TrueCommand reported 3 drives as failing SMART. I manually ran SMART short tests, and this cleared 2 of the alarms, but one won't clear, even though in FreeNas, to the best of my knowledge the disk is fine?

Not sure where to start on this? Possible bug? (screenshot from true command included)

The FreeNas server is my remote offsite backup, which is a 10 Core Xeon, 256Gb of Ram, Supermicro X10SRA-F, and 8x8Tb Reds, (previously as 2 Raidz1 vDevs, now as 1 Raidz1 pool) plus 2x256Gb SSD drives as boot media (in mirror)

All thoughts appreciated.

Interesting!

I’d consider filing it as a bug - the two systems (true command and FreeNAS) should be in violent agreement re: what is and what is not a failing disk. If there is a discrepancy by design, then Truecommand should document those differences to limit head scratching.

In the meantime, I’d replace that disk pre-emptively.

I'll log it, but the disk is only a few weeks old, and as i say, 3 disks had the same errors after I deleted the pool, which cleared after a SMART check. Am reluctant to swap out what i suspect is a perfectly healthy disk. Thanks for the put though :)
