Take a look at the mkfs.xfs man page:
-s sector_size
This option specifies the fundamental sector size of
the filesystem. The sector_size is specified either as
a value in bytes with size=value or as a base two loga-
rithm value with log=value. The default sector_size is
512 bytes. The minimum value for sector size is 512;
the maximum is 32768 (32 KiB). The sector_size must be
a power of 2 size and cannot be made larger than the
filesystem block size.
-Eric
