Hi all, Say If I have a RAID 5 array of 50GB of five disks of 10GB each. I have data of 5GB. When a disk fails and replaced with a spare disk. Will the reconstruction happen only for the 5GB allocated disk blocks or it will happen for the whole disk size. Is it possible to make reconstruction intelligent enough to keep it optimized ? Thanks. -- Regards, Sandeep. “To learn is to change.
