# The script does an accounting of all directories using command 'du' and
# using gluster. We can then compare the two to identify accounting mismatch
# THere can be minor mismatch because gluster only accounts for the size of
# files. Direcotries can take up upto 4kB space on FS per directory. THis
# size is accounted by du and not by gluster. However the difference would
# not be significant.
