How to consume all available space on partition?
Hi
I'm doing some resilience testing and need to write a script to consume all of the available disk space on a partition and then to free it up again.
This would need to be -
Safe
Dynamic, in that it calculates the free space prior to consuming it.
I might want to go on to consume a configurable percentage of it instead...
This would be on a Centos Linux box
Anyone have any experience in this area?

NAME
disktab - disk description file
SYNOPSIS
#include <disktab.h>
DESCRIPTION
Disktab is a simple date base which describes disk geometries and disk partition characteristics. The format is patterned after the term-
cap(5) terminal data base. Entries in disktab consist of a number of `:' separated fields. The first entry for each disk gives the names
which are known for the disk, separated by `|' characters. The last name given should be a long name fully identifying the disk.
The following list indicates the normal values stored for each disk entry.
Name Type Description
ns num Number of sectors per track
nt num Number of tracks per cylinder
nc num Total number of cylinders on the disk
b0 str Filename of block zero primary bootstrap for device
ba num Block size for partition `a' (bytes)
bd num Block size for partition `d' (bytes)
be num Block size for partition `e' (bytes)
bf num Block size for partition `f' (bytes)
bg num Block size for partition `g' (bytes)
bh num Block size for partition `h' (bytes)
fa num Fragment size for partition `a' (bytes)
fd num Fragment size for partition `d' (bytes)
fe num Fragment size for partition `e' (bytes)
ff num Fragment size for partition `f' (bytes)

so bool partition offsets in sectors

Disktab entries may be automatically generated with the diskpart program.
