vxfs_vol_encapsulate_bias

NAME

vxfs_vol_encapsulate_bias - encapsulate a volume within a multi-volume file system

SYNOPSIS

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

#include <sys/types.h>

#include <vxfsutil.h>

int vxfs_vol_encapsulate_bias(char *fname, char *volname, uint64_t size, uint64_t bias);

AVAILABILITY

VRTSvxfs

DESCRIPTION

vxfs_vol_encapsulate_bias() adds the volume specified by volname to the file system, making the existing data starting at byte offset bias in the volume available in the file fname. The size of the resulting file is size - bias bytes. size does not have to be the full size of the volume. bias must be smaller than size and must be a multiple of the file system block size in bytes. 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_bias() returns zero on success, non-zero on failure.

ERRORS

EEXIST

The specified policy name is reserved.

EFAULT

One or more of the specified pointer arguments points to an illegal address.

EFBIG

The calling function issued a request with a file offset off past the EOF mark.

EINVAL

The specified bias is not a multiple of the file system block size.

ENOENT

The specified volume does not exist.

ENOSPC

There was insufficient space to complete the operation.
