Re: Debian support on newer 4K Advanced format drives (rather than 512 bytes)

Not according to man on Stable:
mkfs.xfs [ -b block_size ] ... [ -s sector_size ] [ -L label ] [ -N ] device
-b block_size_options
This option specifies the fundamental block size of the filesystem. The
valid block_size_options are: log=value or size=value and only one can be
supplied. The block size is specified either as a base two logarithm value
with log=, or in bytes with size=. The default value is 4096 bytes (4 KiB),
the minimum is 512, and the maximum is 65536 (64 KiB). XFS on Linux currently
only supports pagesize or smaller blocks.
-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 logarithm 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.
