Another method to see files and extent allocations for a selected volume is
FSCHECK'S extentdistrib ;file command.
An MPE/iX script is included to execute FSCHECK and total the number of files
and extents reported. While this is not 100% accurate, it is closer than the
80% or so, counting files method, and is a good method to see what is happening,
to answer the basic question at hand: Do I have too many files, or too many extents?
If I have too many extents then defragging would definitely be helpful. And, purging
or reallocating files would be a solution,if I have too many files.
