Hi, for once, well populated pools are rarely new. Second, Best Practises recommendations on scrubbing intervals are based on disk product line (Enterprise monthly vs. Consumer weekly), not on redundancy level or pool configuration. Obviously, the issue under discussion affects all imaginable configurations, though. It may only vary in the degree. Recommending to not using scrub doesn't even qualify as a workaround, in my regard.
