Function Documentation

kmr_fefs_get_stripe()

int kmr_fefs_get_stripe	(	const char *	dir,
		const char *	file,
		struct kmr_fefs_stripe *	stripe,
		int *	err,
		_Bool	debug_and_dump
	)

Gets the OBDIDX information on the file or directory.

FILE be null for directory. It fills STRIPE, which contains stripe size, count, offset, and an obdidx array. It returns non-zero on error: 1 for unsupported OS, 2 malloc failure, 3 open failure, 4 ioctl failure (not Lustre FS), 5 bad magic, 6 bad version (V3), and 7 bad pattern. Note the structure and the _IOWR definitions are changed to match the arguments of the Fujitsu FEFS. See the source "cb_getstripe()", near "ioctl(_,LL_IOC_LOV_GETSTRIPE,...)" in "liblustreapi.c".
