Changing Watermark Parameters
Watermarks help you determine disk space thresholds for your file
system. These thresholds determine the point at which StorNext applies
or stops applying a truncation policy. This function also allows you to
specify a minimum usage percentage, which is the percentage of
occupied disk space the nightly truncation policy attempts to achieve.
