Recently was notified of a degraded volume ( a RAIDZ3 ) due to a faulted disk. Nothing out of the ordinary, disks will wear over time and this disk ( the whole server in fact ) are online basically 24/7 for about a year now.
It's a 4TB Seagate IronWolf NAS drive, didn't expect to see it go so soon, but again I get that these occur from time to time.
What's strange...and it's something I've observed ever since I've started using FreeNAS for years now...
Rebooting the system and letting it do a scrub/resilver, the state of the volume went from degraded back to fully healthy! ( did not swap the disk out )
I expected this behavior to happen, because I've seen this "smoke and mirrors" solution work for me for quite some time now. ( going back to some much older versions of FreeNAS too )
Basically...
When I encounter a faulted disk, just reboot, let it resilver and do scrub and everything is back to normal....but how? What happened to the fault? Is it still a faulty drive?
I understand this may just be an early sign of a more severe failure in the future, but I mean for now if FreeNAS reports everything is healthy and normal why should I bother? A dead and clicking drive on the other hand obviously needs immediate replacement.
I purchase IronWolf NAS and RED drives for the extended warranty ( among other reasons ) is a fault like the ones I describe above covered under this warranty? Because unlike other faults, like instance's where the drive clicks or other more fatal faults....I'm not sure if Seagate would recognize a fault and replace the drive? or do they replace a drive you send in to them regardless? Is the fault something they would be able to reproduce in their warranty evaluation?
I will send the drive back without hesitation if I know the drive is:
Looking for other's experience/advice on the matter.

I will send the drive back without hesitation if I know the drive is:
- Truly in a bad state that is bound to have immediate issues in the near future.
- Will be covered under the manufacturer warranty.
