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

int vxfs_vol_encapsulate_bias(char *fname, char *volname, uint64_t size, uint64_t bias);
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.
vxfs_vol_encapsulate_bias() returns zero on success, non-zero on failure.
The specified policy name is reserved.
One or more of the specified pointer arguments points to an illegal address.
The calling function issued a request with a file offset off past the EOF mark.
The specified bias is not a multiple of the file system block size.
The specified volume does not exist.
There was insufficient space to complete the operation.
This operation is not supported by the disk layout version of the specified file system. Use vxupgrade(1m) to enable this operation.
An I/O error occurred during the operation.
The calling process does not have correct access privileges.
The specified file system is mounted read-only.
