Otherwise, the orphan OST-objects will be destroyed.</p> <p>Unfortunately, both the OST stored LAST_ID and MDT given one are 64 bits, but the @diff variable is only 32 bits, and if the OST side value is too larger than the MDT side, then the @diff will overflow. That will misguide the OST to destroy useful OST-objects by wrong.</p> LU-9753
