<BR><BR>The actual total storage used across all the children of stripe will

though ls -lh <file> on each backend reports size approximately equal to
file size (which will make total storage to be equal to n * file-size, n being
number of children of stripe).<BR><BR>sorry for the
confusion.<BR><BR>regards,<BR><BR>

the backend, striped files have holes in those regions data is not present.
Hence size of the files on all nodes is the same. Advantage of stripe is the
speed gained during reads and storage is not saved by striping.<BR><BR>
