set gap

set gap — Set the gap parameter - the size of free space below which it will be assumed that the pool is full within the cost calculations.

Synopsis

set gap <gapPara>

gapPara

The size of free space below which it will be assumed that the pool is full. Default is 4GB.

Description

The gap parameter is used within the space cost calculation scheme described in the section called “The Space Cost”. It specifies the size of free space below which it will be assumed that the pool is full and consequently the least recently used file has to be removed if a new file has to be stored on the pool. If, on the other hand, the free space is greater than gapPara, it will be expensive to store a file on the pool which exceeds the free space.
