SYNOPSIS

cc -I /opt/VRTS/include -L /opt/VRTS/lib
-l vxfsutil -ldl

#include <sys/types.h>

#include <vxfsutil.h>

int vxfs_vol_encapsulate(char *fname, char *volname, uint64_t size);

AVAILABILITY

VRTSvxfs

DESCRIPTION

vxfs_vol_encapsulate() adds the volume specified by volname to the file system, making the existing data in the volume available in the file fname. The size of the resulting file is size bytes, which does not have to be the full size of the volume. Any space in the volume past the portion being encapsulated can be added to the file system as free space by a subsequent vxfs_vol_resize() operation.

RETURN VALUES

vxfs_vol_encapsulate() returns zero on success, non-zero on failure.
