The default striping is specified on a filesystem-wide basis when the LOV
is defined in the lmc configuration script. It is also possible to set
the default striping on a per-directory basis with "lfs setstripe
<dir> ..."
(all new files in that directory will inherit the parent''s stripe
pattern)
and on a per-file basis with "lfs setstripe <new_file> ...".
It is not currently possible to change the striping on an existing file,
you have to create a new file with "lfs setstripe <new_file>
..." and
then copy the data from the old file to the new file.
