Keeping the VDEVs small is one thing, but this is about resilvering spending far more time than reported. The same applies to scrubbing at times. Would it be hard to rewrite the reporting mechanisms in ZFS to report something more likely, than just a first guess? ZFS scrub reports tremendous times at start, but slows down after it's worked it's way through the metadata. What ZFS is doing when the system still scrubs after 100 hours at 100% is beyond my knowledge.
