After watching endless threads about RAID5 arrays losing a disk, and then losing a second during the rebuild, I wonder if it would make sense to: - have MD automatically increase all disk timeouts when doing a rebuild. The idea being that we are more tolerant of a bad sector when rebuilding? The idea would be to NOT just evict disks when in potentially bad situations without trying really hard. - Automatically setup an automatic scrub of the array that happens weekly unless you explicitly turn it off. This would possibly require changes from the distros, but if it could be made a core part of MD so that all the blocks in the array get read each week, that would help with silent failures. We've got all these compute cycles kicking around that could be used to make things even more reliable, we should be using them in some smart way.
