All right, I applied your "[md PATCH 2/7] md/raid10: don't clear bitmap during recovery if array will still be degraded." patch, modified about 2% of my fully degraded raid10, synched the 3 missing devices, compared the mirrors and found no difference, so I guess I can confirm the patch works for me :) regards Mario -- The opposite of a correct statement is a false statement.
