Abstract
A system is employed to maintain persistent operation information for implementation on persistent data. Bitmaps are created to track outstanding persistent operations. Should a volume of information became inaccessible, the bitmaps are evaluated to determine if outstanding persistent operations exist and, if so, these outstanding operations are performed before the volume is integrated into the logical memory space. Additionally, operation-in-progress bitmaps are utilized to indicate that persistent data within a volume is being modified.
