What do you think cause this? I was doing a full scrub then is the only thing i can think of

A full scrub will indeed make your disks very busy. I'd be more concerned that only one of your disks threw this alert at you.

I have a 6 disk ZFS2 setup and 4 of the 6 disks reported same , also once the scrub finished it sent back that it recovered on all the disks that initially reported the warning
