Greetings

Sorry if this is way off this List:

Working on Storage for Databases,

The Goal is : how much space should we have to add to make %free 40% for a given Filesystem

This detail comes from df -k output and or from tablespace free output

I know the following values for a given FS either from df -k or from tablespace calcualtion:

Allocated GB
Used GB
Free GB
%USed
%Free

(even though %used and %free values never add for a df -k output)

I need a formula to come up with a new Allocation size if %free is at 40% (which means %used will be at 60%)

Brain is not thinking stright, appreciate your feedback (My math is not adding up to the xl I have been sent for the new storage required to set all FS at 40% Free)
