Is scrub (sync) needed on RAID10? I've noticed in mdadm monitor logs that it seems to re-allocate data destined for bad blocks on the fly anyway. Maybe I don't quite understand what the scrub does, though :) I ran it for the first time on my RAID last night anyway to make sure all way well since I am failing out a dying disk for replacement today. -- Mark Keisler "I have been here.
