Thanks.
(Yes, I looked at the manual but did not /see/ aka understand what I really needed).
My page is a little bit different:
-s sector_size_options
This option specifies the fundamental sector size of
the filesystem. The valid sector_size_option is:
size=value
The sector size is specified with a value
in bytes. 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.
To specify any options on the command line
in units of sectors, this option must be
specified first so that the sector size is
applied consistently to all options.
Thus the final command line was:
# mkfs.xfs -L ANameUnseen -s size=2048 /dev/mapper/cr_nombre
meta-data=/dev/mapper/cr_nombre isize=512 agcount=4, agsize=3054592 blks
