This test is quite sensitive to resync speed - if the resync happens to quickly it fails because it sees aan optimal array when it expects a degraded array. 1000 is often slow enough but now always, so slow it down even more. This requires reducing speed_limit_min also as kernel ignores 'max' when speed is below 'min'. Reported-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>
