Well, the block sizes are back to 32k now, but I still had no luck
mounting /dev/md0 once I created the array.

Ahem, I missed something.

Your array used layout : left-asymmetric, while the superblock you've
just created has layout: left-symmetric.

Try again, but add the option "--parity=left-asymmetric"
