No worries. I'm taking this back on list as others have more experience
with this than me.

1. Can one create a RAID5 from bare (partition-less) AF drives and avoid
the read-modify-write problem?
2. Or is one required to assemble the array from properly aligned
partitions created on each drive?
Pol, *IF* the answer to #1 is yes, creating the array properly becomes
easier. Simply create the array with raw device names and no partition
numbers, for example, sd[a,b,c,d,e,f]. If you've already created
partitions on the drives, wipe everything off all drives, including the
partitions tables.
If the answer to #1 is 'no', and to #2 is 'yes', then you need to follow
the instructions posted by Erwan Leroux.
