Maybe there is a good reason for this, but I'm going to challenge it.
To cite man mdadm:
Specify chunk size of kibibytes. The default when
creating an array is 512KB. To ensure compatibility
with earlier versions, the default when Building and
array with no persistent metadata is 64KB. This is
only meaningful for RAID0, RAID4, RAID5, RAID6, and
So, actually there's a mismatch with the default of mdadm an mkfs.xfs.
Maybe it's worthwhile to think of raising the log stripe maximum size to
at least 512 kiB? I don't know what implications this could have,
