SYNOPSIS

#include <lustre/lustreapi.h>

int llapi_layout_stripe_size_get(const struct llapi_layout *layout,
                                 uint64_t *stripe_size);

int llapi_layout_stripe_size_set(struct llapi_layout *layout,
                                 uint64_t stripe_size);

DESCRIPTION

The stripe size indicates how much data to write to one OST before moving to the next OST.

llapi_layout_stripe_size_get() stores into stripe_size the stripe size of layout.

llapi_layout_stripe_size_set() sets the stripe size of layout to stripe_size.

A stripe_size value of LLAPI_LAYOUT_DEFAULT means that the default stripe size will be used.

RETURN VALUES

llapi_layout_stripe_size_get() and llapi_layout_stripe_size_set() return 0 on success, or -1 if an error occurred (in which case, errno is set appropriately).

ERRORS

EINVAL

An invalid argument was specified.
