1. Executive Summary & Objective#

Due to hardware failures on Pool 1 (Slot 2 pulled, Slot 3 accumulating 75,000+ write failures), Pool 1 is operating with zero fault tolerance. To prevent data loss prior to receiving warranty replacement drives, all active shares on Pool 1 will be migrated to Pool 2.
