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 _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
