To create a file with specified striping/composite layout, or
create/replace the default layout on an existing directory:
usage: setstripe [--component-end|-E COMP_END]
                 [--copy=LUSTRE_SRC]
                 [--extension-size|--ext-size|-z SIZE]

 or
To add component(s) to an existing composite file:
usage: setstripe --component-add [--component-end|-E COMP_END]
                 [--copy=LUSTRE_SRC]
                 [--extension-size|--ext-size|-z SIZE]

To totally delete the default striping from an existing directory:
usage: setstripe [--delete|-d] <directory>
 or
To create a mirrored file or set s default mirror layout on a directory:
usage: setstripe {--mirror-count|-N}[MIRROR_COUNT] [SETSTRIPE_OPTIONS] <directory|filename>
 or
To delete the last component(s) from an existing composite file
(note that this will also delete any data in those components):

	COMP_FLAGS:  'init' indicating all instantiated components
	             '^init' indicating all uninstantiated components
	-I and -F cannot be specified at the same time
 or
To set or clear flags on a specific component
(note that this command can only be applied to mirrored files:
usage: setstripe --comp-set {-I COMP_ID|--comp-flags=COMP_FLAGS}
                            <filename>
 or
To create a file with a foreign (free format) layout:
usage: setstripe --foreign[=FOREIGN_TYPE]
                 --xattr|-x LAYOUT_STRING [--flags HEX]
                 [--mode MODE] <filename>
