Have you looked at enabling write-intent bitmaps on your raid-1 arrays?
With all the grief I have been having with RAID-1 recently, bitmaps have saved
me very very serious amounts of time resyncing the array.
Typically after my raid array has had devices/partitions kicked out (such as
when loading -mm5) it takes only 2-3 seconds to bring each non-fresh
device/partition back into the array and back up to sync (as opposed to 18
hours...).
Neil wrote a good posting at http://lkml.org/lkml/2005/12/4/118 about it (which
should be a FAQ entry in itself).
