Should I be worried?

Two things, the scrub on the 1st, I dont have a scrub scheduled until the 3rd?

And the resilvering? I did have the machine appart at the time it lists to do some maintenance, this would be when it was powered back on and I had to rollback the OS and set things up again.
Didnt change any hardware but the disks may have been put back in a different order which shouldnt affect anything?

No, I don't think you should be worried.

Did the scrub happen because of how the threshold is set? i.e. if the 1st happened to be when the threshold was exceeded it would trigger a scrub. But I'm not sure about that. In any case, the pool is fine.

Not sure on the resilver though. All I can think of is, assuming usb sticks, is maybe one dropped out (which could be the stick itself, or the controller) and then came back.

I'm assuming USB drives for booting? Is there anything in /var/log/messages or dmesg? You could have a bad boot drive which needs replacing.

Meh. I wouldn't worry much about it. You have a two-device boot pool. The worst case scenario is that one of them is going to die (what kind are they? Please don't say Kingston microDT). If it does, you can simply replace it. If the whole boot pool dies, you can replace that too, without any ill effects. I would suggest making sure you have a backup of your FreeNAS configuration so you don't have to redo that whole thing in the GUI if you loose the boot pool.
