Provided raid1 is where tha data lives, both the RAID and its components are 
quiet.

During which timeframe?

So you mostly get 549-byte write requests?
Could you manually double-check this? It sounds so weird that I'm afraid of an 
error in my script mis-interpreting your tcpdump's output format.

In any case, I'm afraid you are not facing the kind of problems I inadvertently 
became a sort-of-expert in.
Those 549-byte writes, should they prove real, may (others) give a hint what's 
going wrong, though.
